Abstract

‘Making’ describes a process of iterative fabrication that draws on a DIY mindset, is collaborative, and allows for student expression through the creation of meaningful products. While making and its associated practices have made their way into many K-12 settings, teacher preparation programs are still working to integrate making and maker activities into their courses. This paper describes an end-of-semester maker project designed to introduce preservice science teachers to making as an educational movement. The project was implemented in two different higher education contexts, a public university secondary STEM introduction to teaching course and a private university elementary science methods course. The purpose of this article is to share this work by articulating the fundamental elements of the project, describing how it was enacted in each of the two settings, reviewing insights gained, and discussing possibilities for future iterations. The project’s instructional strategies, materials, and insights will be useful for those interested in bringing making into science teacher preparation.

Introduction

Over the past decade, there has been a surge of interest in how the field of education can benefit from the tools, processes, and practices of making (e.g., Clapp, Ross, Ryan, & Tishman, 2016; Fields, Kafai, Nakajima, Goode, & Margolis, 2018; Halverson & Sheridan, 2014; Stager & Martinez, 2013). Drawing from a “do it yourself” (DIY) mindset, classroom-based making can be defined as an iterative process of fabrication that allows students to express themselves through the creation of personally meaningful products that are publicly shared (Rodriguez, Harron, & DeGraff, 2018). Like traditional science and engineering practices, making involves the building of models, theories, and systems (NSTA, 2013). However, in contrast to these practices, making explicitly emphasizes the development of personal agency and student empowerment through creative, hands-on learning experiences that are both exciting and motivating (Clapp et al., 2016; Maker Education Initiative, n.d.). A shift towards maker-centered learning provides an opportunity to rethink how we prepare science educators with the aim of bringing more student-driven and personally meaningful experiences to their instructional practice.

Comparable to project-based learning (PBL) and other inquiry-based teaching practices, classroom making involves learning by doing. Maker-centered learning shares many elements found in High Quality Project Based Learning (HQPBL, 2018) which suggests that projects should include intellectual challenge and accomplishment, authenticity, collaboration, project management, the creation of a public product, and reflection. These elements overlap significantly with features of classroom-based making (Rodriguez, Harron, Fletcher, & Spock, 2018). However, maker-centered learning draws specifically on the theoretical underpinnings of constructionism (Papert, 1991), where learners gain knowledge as they actively design and build tangible digital or physical objects. Furthermore, maker-centered learning places emphasis on the originality and personal meaning of creations, the productive use of tools and materials in fabrication, the process of iterative design, and the development of a maker mindset that is growth-oriented and failure positive (Martin, 2015). Thus, in maker-centered learning, the skills of construction and design are acquired alongside the content.

There are several examples of the tools and materials associated with making being used as a way to help students explore the natural world (Bevan, 2017; Peppler, Halverson, & Kafai, 2016). For example, the use of copper tape, LEDs, and coin cell batteries have provided an avenue for science teachers to introduce circuits through the creation of interactive pop-up books and user-friendly paper circuit templates (Qi & Buechley, 2010, 2014). Sewable circuits, which use conductive thread, have been shown to improve student interest in science (Tofel-Grehl et al., 2017) and can be used in conjunction with embedded electronics, such as the Arduino-based Lilypad, to introduce computer science through the creation of e-textiles (Fields et al., 2018). However, not all making is digital. Making also includes traditional work such as welding, sewing, wood working, and other techniques that exist outside of the computational world.

The National Science Foundation (NSF) has acknowledged the potential of making to foster innovation, increase student retention, and broaden participation in science, technology, engineering, and mathematics (STEM) (National Science Foundation, 2017). However, more must be done to prepare future science educators to implement these practices in their classrooms. A national survey found that only half of undergraduate teacher preparation programs in the United States provided an opportunity to learn about maker-education and the associated technologies, and that only 17% had a makerspace available to their preservice teachers (Cohen, 2017). As such, many future educators are not exposed to formal training or professional development related to making. Since science teachers often uptake and implement the inquiry-based practices with which they have personal experience (Windschitl, 2003), a lack of exposure to maker-centered pedagogies may leave future educators unaware of the potential benefits of these innovations for their students.

This paper describes an end-of-semester project designed to introduce students to making as an educational movement. The project was implemented in two different settings. One was an introductory course offered as part of a secondary STEM teacher preparation program at a large public research university. The other was a science methods course designed for preservice elementary teachers offered at a private university. The purpose of this article is to share our work by articulating the fundamental elements of the project, describing the project as enacted in these two settings, reviewing insights gained, and discussing possibilities for future iterations.

The Maker Project

The maker project described in this paper was introduced four years ago in a secondary STEM teacher preparation course for a number of reasons. The first was to expose novice teachers to the practice of using open-ended projects with high levels of personal agency to uncover student ideas. The second was to spark creativity in the preservice teachers and engage them in the act of authentic problem solving. The final reason was to provide an opportunity for preservice teachers to interact with up-to-date educational tools that they may encounter in schools. Two years later, an elementary science methods course housed in a private university adopted this activity for similar reasons, with the additional hope of increasing preservice teacher self-efficacy around science content and tool use – a noted deficiency in the literature (Menon & Sadler, 2016; Rice & Roychoudhury, 2003; Yoon, et al., 2006).

The following section outlines strategies used to implement the project in the two different science teacher preparation settings. The fundamental elements of the project in both settings include: a) an introduction to making; b) a station activity to expose students to new technologies and materials; c) an open-ended construction task; d) extended out of class time to create a personally meaningful artifact; e) the public presentation of work to classmates, instructors, and guests; and f) reflections for the classroom. Table 1 provides description of each setting and an overview of how the project features were enacted.

Context Specific Implementation

Implementation in an introductory secondary STEM teacher preparation course

The introductory secondary STEM teacher preparation course is a 90-minute, one credit hour class in a large R1 university in central Texas. It meets once a week with approximately 25 students in each of five sections. The class is considered a recruitment course and is designed to give STEM majors the chance to try out teaching. In this class, students observe and teach a series of STEM lessons in local elementary schools. Those choosing to continue with the program will go on to teach in middle and high school settings and ultimately earn their teaching certification in a secondary STEM field. In the Fall of 2018, 53% of the students in the course were female and 47% male. 64% were underclassmen, 36% were either juniors, seniors, or post baccalaureate students, and 59% had either applied for or were receiving financial aid. 46% were science majors, 16% were math majors, 11% were computer science and engineering majors, 4% were degree holders, and the remaining students were assigned to other majors or undecided.

In class. The maker project in this course began with a project introduction day occurring approximately three weeks from the end of the semester. To start, students were introduced to the concept of making through a video created by Make: magazine and presented with a prompt, “What is making?”, to think about as they watch the video (Maker Media, 2016). The video describes making as a DIY human endeavor that involves creating things that tell a personal story. After the video screening, students engaged in a Think-Pair-Share activity where they discussed the initial prompt in small groups and shared ideas in a whole class discussion, often describing making as personal, innovative, open-ended, and challenging (See Figure 1).

Figure 1 (Click on image to enlarge). Student ideas about making.

Next, the criteria for the final maker project was provided. The specific prompt for this project asked students to reflect on their teaching experience and to make an artifact that illustrated the story of their growth over the semester. Students were shown examples of what others had created in previous semesters. Some past projects featured traditional construction and craft materials such as woodworking and papier-mâché while others included digital tools such as 3D printing, block-based coding, and Arduinos. Students were also shown examples of maker projects as enacted in STEM classrooms such as activities that have K-12 pupils creating museum exhibits to learn about properties of water, using paper circuits to create illuminated food webs, and creating interactive cell models using a Makey Makey.

After reviewing project examples, time was spent introducing the class to several digital technologies through a stations activity. Though digital technologies were not given preference for the project, this activity was an opportunity to have students explore some of the digital tools that encourage invention in the classroom. The class was broken into groups and each group was given ten minutes to explore various digital tools and resources including Scratch, Instructables, Makey Makey, and Circuit Playground (See Appendix A). Preservice teachers farther along in the teacher preparation program facilitated the stations and helped current students explore the new technologies. A handout of useful websites and a place to make notes at each station was also provided (See Appendix B). Students rotated stations such that by the end of the activity they had briefly explored each of the technologies. The final part of the project introduction day was a reflective table talk that occurred after the station activity. At this time, students talked with their classmates and discussed ideas for their final maker project. They were encouraged to connect their project to something they cared about or a specific interest.

Out of class. Students were given two weeks to independently complete their maker projects. Students were free to incorporate traditional skills such as crafts, sewing, knitting, wood working, or metal working in their creation. They were also free to use the digital tools explored in class, or to combine digital and traditional tools to make something new. There was no additional class time provided however, the instructor and TA were available to help students outside of class. Students were encouraged to upcycle, or creatively reuse materials they already had, in creating their projects. Additionally, students were provided with a list of campus locations where they had free access to fabrication tools such as 3D printers, laser cutters, and sewing machines. The students had access to a workroom with traditional school supplies and a suite of recycled materials. Students could also check out digital tools from the program inventory. All of these items were available to them at no cost.

Presentation and reflection. On the last day of class, students presented their creations via a gallery walk format with half of the class presenting at one time and the other half circulating and serving as the audience. Students in the course produced a wide array of personally significant artifacts each of which told a story about their specific experience. Other preservice teachers, staff, and instructors from the program were invited to the presentations giving each student the opportunity to exhibit their work to a large audience. At the end of the presentation session, students completed a short reflection on making, classroom applications, and the project experience.

Implementation in an elementary science methods course

Elementary Science Methods (ESM) is a required course for all students seeking EC-6 teacher certification at a private liberal arts institution in central Texas. ESM is a 75-minute class that meets twice each week on the university campus in a general science lab. It is offered in the fall semester only and typically enrolls 24 students.  Students are predominantly in their final year of the preparation program before student teaching and ESM is one of two science classes required for their graduation from the institution. In the Fall of 2018, there were 23 total students in the ESM course. Twenty-two (96%) of the students in the course were female and one (4%) was male. Two (8%) of the students were sophomores and twenty-one (92%) were either juniors or seniors. Fourteen students (61%) were elementary teaching majors, eight (35%) were special education teacher majors, and the remaining student (4%) was preparing to become a bilingual elementary teacher.

Inspired by the project described above, the ESM maker final project was added to the syllabus three years ago to address specific issues observed from previous semesters of work with elementary science teachers in this context. First, many of the students in prior iterations of ESM had low self-efficacy about their ability to learn and teach science. Thus, one goal for implementing a maker project was to boost student confidence by engaging in a creative activity with a concrete product related to a science concept. Two additional goals relate to the original project from the secondary program: To introduce students to current knowledge around emerging trends in technology and science and to stimulate discussion around the value and challenges of authentic inquiry as a means for student learning and engagement. Since the act of making requires a personal commitment to the production of a product, the instructor hoped that this activity would enliven student curiosity and demonstrate the value of open-ended projects for their own elementary classrooms.

In class. As with the secondary STEM maker project, this project was framed as a culminating experience introduced near the end of the semester. Similarly, the first day of the lesson began with a video introduction to making. The lesson also included a rotating station activity with a supporting handout. Due to resource availability and focus on elementary school outcomes, the instructor modified the content of the stations. For this iteration, a paper circuits station and a bristlebot station were substituted for the Circuit Playground and Scratch stations. Emphasis was placed on exploration and play at each station and developing a sense of wonder around the materials or ideas. At the end of the class, groups shared what they noticed about the various activities in small groups and the instructor introduced the project options to the class. Students were given a choice to either: a) create a product that documented learning to use a tool or product that would demonstrate its possible usefulness in elementary science, or b) investigate an aspect of making, write a summary of the research, and create a visual product highlighting what they learned.

The second day of the lesson began with a recap of the project criteria. The criteria for this project, while open-ended to allow for authentic, personally meaningful work, included specific elements that related to state standards for elementary science, attention to safety, a projected calendar and a pre-assessment of how project goals and outcomes related to available tools, equipment, and resources to complete the work (see Appendix C). Students were given time to consider potential project options and discuss their ideas with their peers and instructor.

Out of class. Students were provided three weeks to complete the project before the culminating presentation. This timeframe included the Thanksgiving holiday and many students worked on their product at home.  During the last week of classes, the students were given an additional class day to share their projects in an unfinished state for feedback, to revise and refine their ideas, and to borrow tools from the supply cabinet for completion.

Presentation and reflection. During the final exam period, student products were set up and shared with peers and instructor in a maker exhibition. As in the secondary setting, the project presentations took place science fair style with half of the students presenting and half serving as the audience at any one time. Students also completed a written reflection discussing challenges, reiterating connections to science standards, and reflecting on lessons learned from the experience.

Insights from Project Implementation

While there was no formal data collection included as part of this project, student products and reflections from each setting provide initial insights. Figure 2 provides an overview of general insights as well as those specific to each context.

General Insights

The two contexts for maker project implementation differed significantly. However, insights emerged that were common to both settings. First, in both contexts, the preservice teachers developed a wide range of products including both high- and low-tech creations (see Appendix D). Figure 3 shows: a) a DIY water filtration system; b) an interactive neuron model; c) a series of origami swans; d) soldered paper circuit holiday cards e); a fluidized air bed; and f) an interactive model of a new “teacher” with makey makey fruit controls and related story.

The work produced for this project was personally connected to the interests and motivations of the makers and rooted in the students’ own lives. Second, reflections from preservice teachers in both courses indicate that, through this project, many students experienced the importance of persistence and adaptability when encountering challenges. The open-ended nature of the project turned out to be one of its most important elements as it challenged students develop an original idea and then persist and adapt to bring their idea to life. Third, in both contexts, many preservice teachers described a sense of accomplishment and enjoyment stemming from the creation and presentation of their work. Finally, students in both courses made connections between their maker experience and the process of teaching and learning. Table 2 shows comments from student reflections related to these themes.

Student Comments From Both Maker Project Settings

Additionally, in both settings, the project encouraged some students to take making further. In the secondary setting, multiple students went on to join the maker micro-credentialing program offered by the teacher preparation program. In the elementary setting, several students completed independent projects in the area of making. For example, two students collected data, worked with university faculty and teachers at local makerspaces, and presented their findings on supporting special needs students in making at a local maker education conference.

Insights from an Introductory Secondary STEM Teacher Preparation Course

Written reflections indicate that many members of the secondary STEM teacher preparation course developed a deeper understanding of the nature of making. As an example, one student wrote that “I thought that making was all about electronics and coding but there is so much more…it generates your own creativity and interests.” Another student wrote, “Making is about putting one’s experiences and passions into a project. Making adds a sense of ownership and differentiation.” This was a first exposure to making for most students and their reflections indicate that the project helped them develop a personal conception of what it means to make.

Second, this project helped model the creation of a safe space for exploration and failure for these students. The class mantra during this project was “You can’t get it wrong” and student reflections illustrated their connection with this part of a maker mindset. For example, one student commented, “Making is about growing as an explorer. Making is not being afraid to fail! At the beginning I thought making was trivial but I now see the importance of hands on learning as a chance to really fail.”  Another student said, “During creating, I asked myself ‘Am I doing it right?’ ‘Is this fine?’ and when I was presenting I realized ‘this is totally fine, there is no right or wrong’.” This positive message about failure is not one that STEM undergraduates at large public universities often hear. Thus, for this group, the project provided an essential model for rewarding effort over the commonly prioritized final product.

Insights from an Elementary Science Methods Course

The elementary preservice teachers in the three-hour course showed increased confidence with a wide array of maker tools and equipment such as soldering irons, electronics, and woodworking equipment. The open-ended nature of the assignment allowed students in this course to make a range of high-level products, from a 2D model of a neural cell that used different colored LED’s to show how a neural impulse moves, to holiday cards, to a fluidized airbed. Reflections indicate that many students felt increased confidence with equipment related to their projects. One student commented, “I never thought I’d be able to solder, but after connecting the LED’s to the paper circuit holiday cards, I can do it!  Thanks for giving me the chance to learn this. I want to try making jewelry next.”

The students in the ESM course also made specific connections to teaching science in the elementary context. Student reflections show that they honed in on ideas of agency and engagement as central features of making that would motivate them to do projects of this kind with their future pupils. For example, one student said, “I am totally going to use making in my science classroom because it makes students take responsibility for their own learning and gives them ownership of their work.” Another student wrote, through making “you can make science fun and creative for students allowing them to take control of creating whatever they can dream of.” These reflections illustrate the potential of this project to influence the classroom instruction of these future teachers.

Finally, one unique outcome was that many members of the elementary group experienced making as an opportunity to create with friends and family. The project implementation in this setting coincided with the Thanksgiving holiday, giving many students the opportunity to work with parents or friends. For example, one student shared the specifics of her maker journey with permission.  When the project was introduced, she considered making something for her father as a holiday gift. She initially wanted to learn how to create fly-fishing flies based on her father’s love of fishing. However, the costs of buying materials were prohibitive. A chance visit to a website that showed a video demonstrating the non-Newtonian nature of a fluidized airbed then excited her to consider making her own model to demonstrate this fascinating phenomenon.  After checking that the proper equipment to make a small model was available in her family garage, she traveled home for Thanksgiving with initial instructions.  She worked with her father over the break to bring her creation to life. Like many maker projects, the initial results required refinement. Challenges included compressor issues as well as using the wrong substrate for the bed material. However, she persisted and was able to present her model at the maker exhibition with pride. The student’s build is documented in this video. It highlights her energy and enthusiasm for the work. She recently shared with Steve that she will be refining her initial attempt again, having secured a bigger compressor and better substrate.

While making is a journey that differs for each maker, many of the students in the ESM class included a significant other in their building process. This was an unexpected outcome and may have led to more collaborative and ambitious creations. This insight highlights the potential of making as a community-building endeavor.

Project Management

It should be noted that some students were challenged by the technical details and time required to produce a working product so it is important to provide extended time and to include out of class support. This might include additional office hours and partnering with more advanced students to provide technical support. Consider working with campus engineering, art, or instructional technology departments to find others willing to help with advice on construction and tool use. In addition, instructors should consult with appropriate university departments concerning risk management strategies to ensure student safety. Requiring students who plan to use equipment with potential risk in their projects (woodworking or metalworking equipment for example) to complete safety training is highly recommended. The Occupational Safety and Health Administration provides guidelines for safe hand and power tool use (OSHA, 2002).

Regular check-ins with students are also useful. Instructors implementing this type of activity might encourage students to complete weekly reflections and upload photos to document the evolution of their process. Including documentation practices of this kind models the use of electronic platforms, such as Blackboard or Canvas, now common in many school districts, as portfolio systems that can be used to capture and share the ongoing work of their K-12 pupils.

Discussion

The culminating maker project was an open-ended assignment where students were invited to: a) make an artifact related to STEM teaching; b) present their product publicly; c) reflect on their work; and d) consider classroom applications. In the process of creation and making, the students explored new digital, craft, and construction technologies and created a product of personal significance. Through making, students in the class experienced fundamental aspects of creativity, agency, persistence, and reflection.  These attributes are essential elements of 21st century learning and are traits that early-career K-12 science teachers are expected to model and train their own pupils to embody.  Furthermore, when students integrate scientific practices, disciplinary core ideas, and crosscutting concepts in the authentic products they create, then maker-centered instruction can facilitate NGSS three-dimensional learning principles in a personally meaningful way (National Research Council, n.d.).

This open-ended maker project is adaptable to varied contexts thus, the expertise and goals of the instructor or facilitator will likely shape the student experience. For example, in this project, students reflected on their growth as educators but with a different set of criteria in each setting. For the secondary students who were majoring in a STEM field, self-efficacy around science content was not an issue. Because the course was only one-credit hour, creativity and effort producing an open-ended product was emphasized. Additionally, the TA for this course was well-versed in maker-related electronics and provided extra support to students attempting novel projects with these tools. In the Elementary Science Methods course, the instructor focused on connections to science standards and building confidence in the use of basic tools, with which he had extensive experience. Thus, this project can be used to achieve a wide array of outcomes and instructors should be thoughtful about their project aims from the start, paying special attention to providing a wide range of practice, play, and examples from the maker world. Connecting to local makers, artisans, and craftsman can expand the project’s reach.

Furthermore, in both courses, equitable teaching and learning are addressed during other activities. However, because making is often situated in a privileged and gendered paradigm (Vossoughi, Hooper, & Escudé, 2016), future iterations of this activity could include an element that explicitly examines how students can negotiate the opportunities and challenges of the activity in diverse classroom settings. Explicit reflections on equity and readings on these issues as they relate to maker education would be productive additions for future iterations.

Conclusion

Tenacity in the face of adversity is a common trait among successful teachers who must evaluate and adapt their teaching to new situations on a daily basis, and who undoubtedly fail many times but use those failures to learn and grow. In the same way, this culminating maker project was scary, messy, exciting, and inspiring. While student projects rarely turned out as planned, student reflections suggest that the experience helped them to value and embrace this ill structured process. As future teachers, this maker experience may be critical in helping our newest practitioners envision a classroom space where students are personally connected to content, have ownership of their learning, are given the freedom to explore and create without fear, and are encouraged to persist in the face of challenges. In this way, including a project that addresses elements of making and fosters a maker mindset can be a valuable step toward preparing preservice teachers to bring innovative and inspirational practices to science education.

Abstract

There are many affordances of integrating classroom-based global collaboration (CBGC) experiences into the K-12 STEM classroom, yet few opportunities for STEM preservice teachers (PST) to participate in these strategies during their teacher preparation program (TPP). We describe the experiences of 12 STEM PSTs enrolled in a CBGC-enhanced course in a TPP. PSTs participated in one limited communication CBGC (using mathematics content to make origami for a global audience), two sustained engaged CBGCs (with STEM PSTs and in-service graduate students at universities in Belarus and South Korea), and an individual capstone CBGC-infused project-based learning (PBL) project. Participating STEM PSTs reported positive outcomes for themselves as teachers in their 21st century skills development and increased pedagogical content knowledge. Participants also discussed potential benefits for their students in cultural understanding and open-mindedness. Implementation of each of these CBGCs in the STEM PST course, as well as STEM PST instructors’ reactions and thoughts, are discussed.

Abstract

Preparing preservice early childhood teachers to teach about Nature of Science (NOS) in their science lessons can provide challenges to the methods course instructor. Early childhood science methods course instructors generally agree that early childhood preservice teachers enjoy using children’s literature in their instruction. Preservice teachers can write and design children’s books that can help them to not only refine their own understandings of NOS aspects, but also to consider how to introduce these ideas to young children through their stories. These stories can support the teaching of NOS through hands-on activities in the classroom. The authors tracked a class of early childhood preservice teachers over the course of a semester to determine their ideas about NOS and their depictions of NOS in a storybook they designed for young children. The authors determined whether these NOS ideas were depicted accurately and in a way that could be conceptualized by young children. It was found that nearly all of the preservice teachers were able to portray the NOS aspects accurately through their stories, and that not only did the stories hold promise of introducing these NOS ideas in an engaging manner for early childhood students, but the preservice early childhood teachers also refined their own understandings of NOS through the assignment.

Introduction

An appropriate understanding of nature of science (NOS) is considered important for reform efforts in the USA, and is highlighted in the Next Generation Science Standards (Achieve, 2013). Studies have shown that preservice and inservice early childhood teachers can develop strategies for emphasizing NOS that improve student understandings of NOS (e.g. Conley, Pintrich, Vekiri, & Harrison, 2009; Deng, Chen, Tsai, & Chai, 2011, Khishfe & Abd-El-Khalick, 2002). Teachers have called for support through different strategies they can use in their classrooms (Akerson , Pongsanon, Nargund, & Weiland, 2014). Akerson, et al (2011) has found that using children’s literature is one effective strategy for emphasizing NOS to elementary students. Additionally, preservice early childhood teachers are often more excited about children’s literature than science, and so using children’s books within science methods courses can help preservice early childhood teachers improve their experiences within science methods and see how their strengths and interests in literature can connect to science instruction (Akerson & Hanuscin, 2007).

It has been the first author’s experience in teaching early childhood science methods that early childhood teachers are excited about using children’s books to support their NOS and science teaching. However, these same preservice teachers have been frustrated that they were unable to find a children’s book that would introduce the NOS aspects they wish to teach at early grade levels. The instructor believed that a good way to support the preservice teachers in both their understandings of NOS, and their wishes to teach it to their early childhood students, that the teachers could be supported in developing their own children’s books to use with their students. In this case, a course assignment was designed to help preservice teachers conceptualize how to transfer their knowledge about NOS to early childhood students through a children’s book they designed.

Based on the NSTA (2000) position statement for what teachers should know about NOS and what they are responsible for teaching their own students, the course instructor emphasized the following NOS aspects in her class: (a) scientific knowledge is both reliable and tentative (we are confident in scientific knowledge, yet recognize claims can change with new evidence or reconceptualizing existing evidence), (b) no single scientific method exists, but there are various approaches to creating scientific knowledge, such as collecting evidence and testing claims, (c) creativity plays a role in the development of scientific knowledge through scientists interpolating data and giving meaning to data collected, (d) there is a relationship between theories and laws in that laws describe phenomena and theories are scientific knowledge that seek to explain laws, (e) there is a relationship between observations and inferences with inferences being interpretations made of observations, (f) although science strives for objectivity there is an element of subjectivity in the development of scientific knowledge, and (g) social and cultural context plays a role in development of scientific knowledge, as the culture at large influences what is considered appropriate scientific investigations and knowledge.

To ensure that the preservice teachers held sufficient NOS content knowledge we measured their conceptions of NOS using the VNOS-B (Lederman, Abd-El-Khalick, Bell, & Schwartz, 2002), and also again midway through the semester, and again at the end, to determine sufficient content knowledge and to determine whether thinking about how to teach NOS to young children may influence their own ideas. The VNOS-B does not explicitly ask about the existence of a single scientific method, but does include the empirical NOS, meaning that scientific claims and development of scientific knowledge requires empirical evidence and data. The table below shows their changes in NOS conceptions over the semester.

Table 1 (Click on image to enlarge)
Preservice Early Childhood Teachers’ NOS Conceptions Over Time

For the storybook project, the instructor asked preservice teachers to  introduce all NOS ideas except the distinction between theory and law, as that is not in the early childhood curriculum. Previous research has found that early childhood preservice teachers and their students can conceptualize these NOS ideas, (Akerson & Donnelly, 2010),  and therefore we believed that including them in a children’s book would be a good way to introduce these NOS  ideas to young children. The first author was the instructor of the course, and kept a teacher/researcher journal throughout the course. The other two authors aided in ensuring the instructor was teaching NOS using explicit reflective instruction by observing each class session, taking notes of student engagement and NOS instruction, as well as photographing students working, and in analyzing effectiveness of the development of the books and instruction using the data collected as a team.

The Course Design

The project was introduced at the beginning of the semester long methods course as something the preservice teachers would work toward completing as a final “exam.” Indeed, the project replaced the final exam period for this section, and instead the preservice teachers had a book-share where the preservice teachers shared their books with the rest of the class. The NOS elements that were targeted in this project and were to be included in the book are the tentative but reliable NOS, the creative NOS, the distinction between observation and inference, the empirical NOS, the sociocultural NOS, and the subjective NOS. These NOS ideas were included because they lend themselves to connections in the early childhood curriculum, and have been previously found to be accessible to young children (Akerson & Donnelly, 2010).

To prepare the preservice teachers to develop such a book, the instructor needed to make them aware of ideas about  (a) NOS, (b) elements of children’s books, and (c) the technology they could use to aid them in their design. As is common in the practice of the course instructor, NOS was a theme in the methods course, and NOS was included explicitly in each class session, and debriefed in the context of science content that was explored as examples of instructional methods for early childhood students. The instructor modeled how to explicitly debrief for NOS conceptions each week. For example, during an investigation that included an exploration of Oobleck and whether it is solid or liquid, the instructor modeled questions to ask students regarding NOS during the debriefing to ensure explicit connection to NOS. One such question connected “subjectivity” or the background knowledge that scientists bring to a problem. The instructor asked the preservice teachers to think about how scientific subjectivity could be highlighted through this exploration. The instructor asked “what could the scientists do when they found this substance that did not fit into either classification?” A discussion followed regarding that if scientists understand solids, and understand liquids, then they would realize that this substance has components of both. The discussion ensued that it would therefore it would be difficult to categorize into one or the other. The instructor led them to realize that it was scientists who create the categories of matter, through empirical evidence and creativity. The instructor therefore helped the preservice teachers come to the realization that scientists are also creative, that they could create a new category into which they could classify the Oobleck. The instructor used explicit reflective NOS instruction to help them make a connection beyond simply teaching the distinction between observation and inference through this activity, they could connect other NOS aspects, such as subjectivity and creativity. Such activities and NOS debriefings took place on a weekly basis during the science methods course. The discussion continued with preservice teachers reflecting on how to use similar activities with young children. The instructor shared that this activity could be used as an assessment and instructional sequence for not only young children’s understandings about characteristics of solids and liquids, but also for how scientists are creative scientifically, in terms of “creating” new categories for matter, and how scientists use evidence, observations and inferences, and how claims are tentative given they can, and do, create new categories based on evidence. Additionally, given students’ prior knowledge about characteristics of solids and liquids were used to determine characteristics and identity of the new substance, conversation surrounding the importance of background knowledge, and subjectivity of scientists can occur between the teacher and students.

Using Children’s Books

The science methods instructor spent time in the methods course using children’s literature to both launch and support science activities as an example for how to use such books to emphasize NOS with children. For example, the instructor read the Skull Alphabet Book (Pallotta, 2002). In this book the reader sees an illustration of a skull, reads clues, and tries to infer the animal the skull would be from. There is a different skull from A to Z. Using this book is an example of decontextualized NOS instruction (Bell, Mulvey, & Maeng, 2016; Clough, 2006), if the instructor makes explicit connections with the preservice students. The instructor led a discussion with the preservice teachers for how this book could be used to explicitly illustrate NOS elements to elementary students. For instance, the elementary students could be asked which NOS elements are illustrated in the book-to which they could respond “Observation and inference” (observing the skull and reading the clues, and inferring the animal), “creativity” (creating an idea of what the animal might be from the evidence), “subjectivity” (one would not infer an animal that one had never heard of before), “empirical NOS” (making inferences from data), “social and cultural NOS” (one would be more likely to infer an animal from the culture they are from), and “tentativeness” (one can infer an animal and be likely correct, but never be certain because it is a skull and without seeing the living animal it is not certain). While the instructor shared this book with the preservice teachers she explicitly pointed out these ideas about NOS that could be connected to the book for children. These kinds of discussions and book debriefs were held weekly over the course of the semester, connected to children’s books as well as science concepts.

Following the use of the children’s book in introducing science concepts, the preservice teachers could think about engaging elementary students in science activities and investigations and reflecting orally or in writing how what they were doing was similar to the work of scientists. For example, preservice teachers could distribute fossils to their elementary students, asking them to make observations and inferences about the whole organism and its likely habitat. The elementary students could be asked to infer and draw the remainder of the organism and its habitat. A debriefing discussion could take place where elementary students could discuss how their inferences came from observations of the empirical data—the fossil, how they used their background knowledge (subjectivity) to make their inferences, and how their ideas about what the fossil was from might change if they had more information. Additionally, elementary students could discuss how scientists create ideas from the evidence, as they did, and how these creations would be consistent with what they are familiar in their own social and cultural contexts.

The course instructor also shared a variety of children’s books with the preservice teachers. These samples of children’s literature books varied from non-fiction to fiction, and were used to explicitly share components of children’s picture books. Features that were highlighted were (1) strong characters, (2) a story that teaches (in this case, the story would teach NOS), and (3) interesting and clear visual drawings or representations of the story.

Designing their own NOS Books

The preservice teachers were not required to use technologies such as Book Creator, or other book development applications to create their books. However, most preservice teachers took advantage of the technology to create their books, particularly for the illustrations.  One preservice teacher who was artistic decided to create her book through drawing and produced a hard copy of the book. The preservice teachers were provided with the following criterion sheet to use while designing their book to enable them to conceptualize what to include in the book (See Table 2):

Table 2 (Click on image to enlarge)
Scoring Rubric for the Create a “Book” Assignment

The books that were created by the preservice teachers were mostly very well done in terms of introducing NOS aspects to young children. There were a total of 22 preservice teachers in the class, all female. Ten preservice teachers connected their NOS books to popular characters from children’s media (e.g. SpongeBob Squarepants and the Case of the Missing Crabby Patty) or books (e.g. The Pigeon Does an Investigation). Ten preservice teachers created their own stories from scratch (e.g. Marcy Meets the Dinosaurs). Two did not consent to have their books used as examples, so they are not included. Therefore the preservice teachers were free to either modify an existing story, which aided in identifying illustrations as well as a storyline, or to create their own to illustrate NOS. Half of them did select to modify an existing story, which enabled them to embed NOS elements into a story that already existed, freeing them to consider how NOS may fit into a story already suitable for young children.

As a methods instructor, it is important to help the preservice teachers consider ways to transfer their understandings of NOS to young children through the text. It was a difficult point for some to think about, and to consider how to phrase sentences to accurately portray NOS, but in a way accessible to children. Using feedback loops this process became more streamlined, where preservice teachers provided feedback to one another. Of the twenty books submitted, all but three included all NOS aspects accurately depicted. Three books did not include subjective or sociocultural NOS. One book also did not include tentative NOS or the distinction between observation and inference. Of the aspects that were included, all but one preservice teacher included accurate representations.

Though not required, five preservice teachers included the distinction between theory and law in their children’s books. While it is clear that simply an accurate presentation of NOS ideas is not sufficient to teach NOS to young children, it is a starting point for the preservice teachers to have an accurate representation of the ideas to begin their teaching, which of course, would require explicit-reflective NOS instruction (Akerson, Abd-El-Khalick, & Lederman, 2000). Use of these children’s books would require that the preservice teachers make explicit reflective connections while sharing with young children.

Ensuring Quality

We reviewed the children’s stories created by the preservice teachers to determine whether the NOS concepts were included accurately. All authors conducted a content analysis on the accuracy of the NOS aspects that were incorporated in the stories. The authors also used the NOS children’s books to determine the preservice teachers’ NOS conceptions at the end of the semester. These sources of data were reviewed independently and then compared to ensure valid interpretation of NOS conceptions both within the books and conceptions held by the teachers themselves. The teacher/researcher log and field notes were used to further triangulate interpretations of the data.

How Well Do Children’s Books Include NOS?

It was clear that preservice teachers not only improved their NOS conceptions over the first eight weeks of the semester, but also during the last seven weeks when they were developing the books to use with their own future students, and to share with their classmates. Below we now share samples of how the preservice early childhood teachers included the various NOS aspects in their stories, by NOS aspect.

Tentative NOS

Eighteen students were readily able to incorporate the tentative NOS into their stories in a way that they could share this characteristic of NOS with their own students. All of the stories included a scientist or a character in the story revising an inference based on new evidence or the reinterpretation of existing evidence, and making a new claim. In all stories the story included this idea as part of science, and not that the scientists were “wrong” with their earlier inference.

Figure 1 (Click on image to enlarge). Sample of tentativeness in storybook.

In other stories there was a more direct description of the tentative NOS. For example, Sophia’s story (see above) was set within an alien culture, and began with the lead character saying “ Hi my name’s Meep and I come from the planet NOS. On planet NOS, we live by set of rules called Nature of Science.” She continues her story showing illustrations that Meep is visiting earth and tell people how they use aspects of NOS. The image above is presenting tentativeness of science. Though her idea is not technically “correct” in that NOS is not a set of rules to live by, nor do ideas “constantly change as we collect data,” it is still along the right track in helping younger children realize that science is not “set in stone” and scientific claims are subject to change.

Observation and Inference

Similarly, eighteen stories included an accurate representation of observation and inference. In most of these stories scientists made observations of data, and then made inferences of what they observed. For example, Emma wrote a story in which a scientist who was a mother was talking to her son Jack, about science. She introduces “observation and inferences” by immersing them in her story about Safari animals. The following illustration shows Jack’s learning of observation and inferences in the story:

Figure 2 (Click on image to enlarge). Sample of observation and inference in storybook.

In this particular example, the author was able to make a connection where the reader would learn about observations and inferences as data were observed, and then could later connect to the tentative NOS as the claim changed with more evidence as further reading of the story showed the ideas changed and tentativeness was connected.

Empirical NOS

All twenty books included accurate depictions of the empirical NOS. In each case the main character, often a scientist, needed to collect data to solve a problem or make observations. Olivia wrote an original story about the lives of three chipmunks in a forest. In the story the chipmunks are keeping safe from hawks, and are doing a scientific exploration in the forest to determine how they are remaining unseen by the hawks. Their exploration leads them to understand camouflage.

Olivia uses following example to show science is empirical, as she also connects it to the tentative NOS. The chipmunks had their own personal “theory” for why the hawks were not able to see them, but changed their ideas as they collected new evidence through empirical data.

Figure 3 (Click on image to enlarge). Sample of scientific tentativeness in storybook.

While this story above is accurate in terms of NOS, it is also the case that the writing was at a level beyond what K-2 students could read on their own. This book would need to be a read-aloud by the teacher to the students, and would likely require much teacher input to help young learners accurately conceptualize the content. Therefore it would be necessary to aid preservice teachers to consider thinking about the reading level and vocabulary for independent reading, which appeared to be difficult for some preservice teachers.

Creativity and Imagination

Eighteen of the stories included accurate representations of creativity and imagination in the development of scientific knowledge. Ava introduces and immerses well the aspects of NOS in her storybook about Pinocchio. In the book, Pinocchio tries to figure out why his nose is growing using scientific inquiry, and through that inquiry the elements of NOS are illustrated.

Through her story she would be able to share with her early childhood students that scientists are creative in interpreting data as well as creating investigations, and in this case in her story, in creating a way to figure out that Pinocchio’s nose grows when he lies. It was clear through her story that those who use science are creative, and that aspects of NOS are part of scientific inquiries.

Though her use of text is beyond the independent reading level of most K-2 students, the story is accurate with regard to NOS concepts, and could be used as a read-aloud with explicit reflective instruction by a teacher. Following is her illustration that shows scientists are creative:

Figure 4 (Click on image to enlarge). Sample of scientific creativity in storybook.

Subjective NOS

Eighteen stories included an accurate depiction of the subjective NOS, in which scientists’ own backgrounds influence their interpretations of data. In the stories it was usually the case that the scientific claim was shown to be made partially through the understandings of the scientist or the one doing the investigation. Mia used characters from a popular children’s story The Three Little Pigs, to teach NOS elements throughout the story. In her story the main character Mr. Wolf guides the three little pigs to act as scientists as they try to figure out whether their houses are sturdy enough to withstand the hurricane. Through these characters, Mia illustrates that scientists are subjective, and use their background knowledge in making scientific claims. As we can see from the excerpt from her story, she clearly illustrates the pigs’ subjectivities helps in making scientific claims.

Figure 5 (Click on image to enlarge). Sample of the role of subjectivity in storybook.

Sociocultural NOS

Fifteen of the stories included accurate depictions of the influence of sociocultural mileu on scientific claims. In some of the books, such as Sophia’s story from the alien perspective, the clash of different cultures was used to illustrate the influence of sociocultural aspects on scientific claims.

In other books, such as the one by Isabella, there is a learning sequence where a character develops an understanding of the role of culture. In Isabella’s particular story a child named Mary meets a paleontologist (Dr. Jenkins) at a science museum. Mary has an adventure at the science museum, and learns that scientists (and other people) interpret data through the culture in which they live.

Mary learned from Dr. Jenkins that her own inference that a dinosaur’s long neck was like the dinosaur’s came from her social and cultural context. Mary learned that because if she were in a culture without knowledge of giraffes she would not have inferred that similarity.

Theory and Law

Again, though not required to include the distinction between theory and law in their stories given it is not in the early childhood curriculum, five preservice teachers did find ways to incorporate theory and law into their stories in accurate ways.

Emma included it in her story of the mother scientist teaching her son about science and NOS. She was one of the few preservice teacher authors who also incorporated the idea that theories never become laws. The others who included theory and law in their stories were clear that theories were explanations for patterns in data that determined laws. It was good to see that there were several who included theory and law—this was the most difficult aspect for the preservice teachers to gain good understandings of as well.

Assessing the Children’s Books, and Implications

All preservice teachers shared their books with each other at the end of the semester in a book share. In addition, the preservice teachers uploaded electronic versions of their books to a course website that could then be accessed by the course instructor, and electronic copies shared with all students in the class. The course instructor used the criterion sheet shared earlier to review the books for the required elements prior to the book share. Each week after the assignment was introduced there was time to discuss questions or concerns regarding the development of the books. Some preservice teachers indicated a difficulty in conceptualizing an original story, which is when the idea came to take an existing story and revise as a NOS story.

An important component was the inclusion of engaging characters and an interesting story that would teach about NOS, not necessarily a story with original characters. However, some preservice teachers designed their own characters and storylines. In one case, the instructor required a preservice teacher to revise the book prior to sharing as the information was not complete. The books were well received by their peers, and the book sharing had an air of both professionalism, as the preservice teachers were considering how best to aid their own students in conceptualizing NOS, and also “fun,” as it was energizing and fun to see and listen to the stories that were created by the preservice teachers in the class.

The preservice teachers indicated that the assignment seemed valuable to them, as it was something they could take with them into their student teaching, and into their classrooms when they became teachers. They provided feedback to one another during the book sharing, suggesting some wording changes, as well as reinforcing the accuracy of portrayal of NOS ideas when it was needed. It was clear that developing the books helped the preservice teachers think about how to introduce NOS ideas to their elementary students. This focus on ways to portray NOS ideas to elementary students influenced the preservice teachers in refining their own NOS understandings as well as about how to transfer understandings to students. The preservice teachers held good understandings of NOS as evidence by their portrayal of NOS concepts to young children through the story they created. It seems clear to us that designing the children’s books to teach about NOS to their students helped the preservice teachers consider ways to teach NOS to their own students, while continuing to refine their own understandings about NOS. We recommend the use of literacy to  teach about NOS, which seems preservice teachers are very excited to include in their classrooms.

Abstract

To successfully implement the Next Generation Science Standards (NGSS), more than 3.4 million in-service educators in the United States will have to understand the instructional shifts needed to adopt these new standards. Here, based on our recent experiences with teachers, we introduce a professional learning (PL) strategy that employs collaborative video analysis to help teachers adjust their instruction to promote the vision and learning objectives of the Standards. Building on effective professional development characteristics, we created and piloted it with teachers who were working on making student thinking visible. In our setting, it has been effective in providing relevant, sustainable changes to in-service teachers' classroom instruction.

Abstract

The Next Generation Science Standards (NGSS) and the Framework for K-12 Science Education (NRC, 2012) on which they are based, require a shift in preservice science teacher preparation. NGSS aligned instruction calls to engage learners in the use of authentic science and engineering practices (SEPs) and crosscutting concepts (CCCs) to develop understanding of disciplinary core ideas (DCIs) within the context of a scientific phenomenon (Bybee, 2014; NRC, 2015). To ensure beginning teachers are prepared for this shift, university programs are changing teacher preparation to meet this new vision. This happens primarily in science methods courses where specific supports must be in place to prepare preservice teachers and facilitate course reforms (Bybee, 2014; Krajcik, McNeill, & Reiser, 2008). This paper describes the Next Generation Alliance for Science Educators Toolkit (Next Gen ASET) that was designed to support shifting instructional needs within science methods courses to align with the vision of the NGSS. While not meant to replace existing methods course curriculum, this toolkit promotes dialogue explicit to the vision of the NGSS. Two teaching scenarios demonstrate how the Next Gen ASET Toolkit has been implemented in science methods courses, illustrating its flexibility of and how they accommodate the inclusion of various lesson planning and instructional styles.

Introduction

The Next Generation Science Standards (NGSS) and the Framework for K-12 Science Education (NRC, 2012) on which they are based, require a shift in preservice science teacher (PST) preparation. NGSS aligned instruction calls to engage K-12 students and new teachers in the use of authentic science and engineering practices (SEPs) and crosscutting concepts (CCCs) to develop understanding of disciplinary core ideas (DCIs) within the context of a scientific phenomenon (Bybee, 2014; NRC, 2015). Therefore, it must be modeled for PSTs how to weave together these three dimensions in the classroom, as they will be expected to align instruction with these goals as they begin their teaching careers.

At the university level the instructional shifts required to align teacher preparation to meet the vision of the Framework and NGSS are most likely to happen within teacher credentialing programs by revising or replacing some of the components of the science teaching methods courses (Bybee, 2014). Yet to accomplish this, science education faculty leading these efforts require tools or supports that assist PSTs to explicitly unpack standards and illuminate their underlying components (Krajcik, McNeill, & Reiser, 2008). Tools that have undergone systematic analysis and field-testing in real education contexts are required for facilitating such understanding (Bryk, Gomez, Grunow, & LeMahieu, 2015; Lewis, 2015). The Next Generation Alliance for Science Educators Toolkit (Next Gen ASET) presented in this paper was designed to provide such scaffolds to prompt discussion and lesson planning that align with the goals of the NGSS. The toolkit and examples of its integration into science methods courses are featured here.

The Next Generation Alliance for Science Educators Toolkit (Next Gen ASET)

Science educators, scientists, and curriculum specialists worked collaboratively over the course of three academic years to develop the Next Gen ASET Toolkit and integrated these tools into science methods courses across six universities. The Improvement Science (IS) framework (Berwick, 2008; Bryk et al., 2015; Lewis, 2015) informed the design of this study in developing and revising the toolkit in methods courses over this 3-year period. This approach allowed for an iterative design process that involved feedback from both the practitioner and end-users as well as for revisions of the tools as they were implemented as part of instruction.

The Next Gen ASET Toolkit is designed to support science methods course instruction to shift towards NGSS-alignment. This includes consideration of how to effectively integrate the three dimensions outlined in the Framework (NRC, 2012) while still considering other effective instructional practices in science education that are commonly addressed in methods courses. The toolkit consists of a one-page overarching graphic organizer (3D Map) and a set of eight tools with guiding criteria to support understanding of the individual SEPs (SEP Tools). A digital version of the toolkit was created to further support its use in methods courses (https://www.nextgenaset.org). The website provides access to the most current versions of the 3D Map and SEP Tools as well as descriptions and supports specific to the use of each. The tools are not meant to be used in isolation, but with peers to promote discourse for understanding the goals and aligning instruction for the NGSS. When used as part of a science methods course with direction from the instructor, these tools can support PSTs to align instruction to the NGSS vision. The following sections further describe the 3D Map and SEP Tools, followed by examples of how these have been used in methods courses.

3-Dimensional Mapping Tool (3D Map)

The 3D Map (Figure 1) was developed as a one-page graphic organizer to help ground discussions of curriculum and instruction in the dimensions of the NGSS, while linking these to larger topics generally discussed as part of instructional planning in a science methods course. The inclusion of topics outside the three dimensions of NGSS as part of the 3D Map extended beyond simply identifying the standards being used in a lesson, and to make connections of how these can be effectively aligned with instructional practices in the science classroom. The 3D Map was not intended to replace the use of more traditional lesson planning templates or other supports, but instead complement and provide a structure for making explicit the ways in which a lesson or unit integrates the components of NGSS. The 3D Map allows enough flexibility in its use to accommodate consideration of existing teaching strategies typically included in a methods course.

The structure of the 3D Map

The 3D Map is arranged with four rows of boxes, each labeled with an instructional component to be considered with room for notes or description of how each of these elements is addressed in a given lesson or unit. The top two rows of boxes on the 3D Map link to larger topics generally discussed as part of lesson planning in a science methods course and arose from consideration of how this tool would integrate with the other course topics. The bottom two rows of boxes include each of the three dimensions of NGSS and spaces for describing how these three dimensions are connected within a lesson or unit. The individual boxes are connected with arrows to indicate relationships between elements with respect to lesson or unit planning.

The top row of boxes includes elements to help orient PSTs and identify the context, goals, and boundaries of a lesson or unit. From left to right this top row has boxes for “Grounding Phenomenon/Essential Question,” “Conceptual Goals,” and “Performance Expectations.” The placement of the “Grounding Phenomenon” box in the upper left corner of the map was intentional, to prompt users to explicitly consider phenomena at the beginning of the planning process, and to promote anchoring lessons to a natural phenomenon while examining existing science instructional segments or planning for new ones. Given that a phenomenon serves as the driver of the science lessons (NRC, 2012), teacher preparation programs need to include a focus on developing teachers’ abilities to engage their students in explanations of natural phenomena (Kloser, 2014; NRC, 2015; Windschitl et al., 2012). The separate box for “Conceptual Goals” was included to allow users to translate this visual phenomenon they planned to explore into a scientific context. The third box, “Performance Expectation(s)” was included to prompt consideration of these larger learning goals as defined by the NGSS.

The second row of boxes prompts the identification of “Learning Objectives” and “Assessments.” The inclusion of a box labeled “Learning Objectives” separate from the “Performance Expectation(s)” (PEs) box was purposeful.  The intent was to signal PSTs to consider the relationships and differences between this larger benchmark for proficiency in science (i.e., PEs) and the smaller lesson-level learning goals in an instructional segment (Krajcik et al., 2014). Current literature indicates that PEs as written in the standards are not meant to be used as lesson-level learning goals (Bybee, 2013; Krajcik et al., 2014); “many lessons will be required for students to develop skills to reach proficiency for a particular NGSS performance expectation” (Houseal, 2015, p. 58). The separate box “Learning Objectives” was therefore included to prompt PSTs to write more specific learning goals based on, but more narrow in scope than, the PEs. The “Assessment” box was included to align with the structure of backward design (Wiggins & McTighe, 2001), an important component of many methods courses, and utilized within the course the 3D Map was originally developed. Consideration of assessment was intended to support PSTs to develop understanding of how to effectively assess learning goals for a lesson or unit, a key component of planning effective instruction (Davis, Petish, & Smithey, 2006). While the assessment box has an arrow connecting with the box for learning objectives, it does not make a connection with the larger PEs since the goal was to include assessments specific for the lesson or unit level, not these larger goals defined by the NGSS.

The bottom two rows of this graphic organizer consist of boxes for PSTs to list specific components of each NGSS dimension present in the lesson or unit, and then to describe how connections among the dimensions were made explicit (NRC, 2012). This design mirrors the integration of the three dimensions provided in the Framework and the NGSS and is consistent with literature providing the rationale for explicating connections among the dimensions for both content and learning objectives (Houseal, 2015; Krajcik et al., 2014). The structure includes color-coding to match the representation of SEPs in blue, DCIs in orange and CCCs in green. The colors of the boxes for the three dimensions of the NGSS and associated connecting arrows were chosen to align with the colors used by Achieve in the NGSS (NGSS Lead States, 2013) to provide a visual connection back to the standards. The visuals and discrete boxes in the 3D Map promote a constructivist approach to co-creating a group understanding of the shifts in pedagogy and curricular structure necessary to implement the integrated and complex components of the NGSS.

Science and Engineering Practice Tools (SEP Tools)

The SEP Tools (see Figure 2 for example) were developed for use in conjunction with the 3D Map to help PSTs identify specific components of a SEP to hone objectives in a given lesson or unit. At first glance the eight SEPs outlined in the NGSS appear straightforward to many PSTs. However, the description of each SEP in the Framework (NRC, 2012) presents a much more complex vision. The goal of the SEP Tools is to make this complexity more explicit. A brief description is provided at the top of each SEP tool as defined in the Framework (NRC, 2012).  Below this description, the tool lists separate subcomponents that classroom students should experience in structured opportunities across the 6-8 grade band in order to completely engage in that SEP. These components are arranged on the left side of a matrix with columns to the right where PSTs may indicate which of these components from a given SEP are present in a lesson. There is also space on the tool to describe evidence of each component, including the actions a teacher takes to facilitate these components as well as how the students are engaging in each.

This matrix for completion by the PSTs detailing the SEP subcomponents is formatted to fit on 1-2 pages depending on the number of subcomponents. The criteria included on the last page of each SEP Tool is meant to be a reference for each component, defining for PSTs what students should do to have a structured opportunity to develop an understanding of each component by the end of the 6-8 grade band, as described in the Framework (NRC, 2012).

Figure 2 (Click on the following link to view). Science and engineering tool example.

Implementing the Next Gen ASET Toolkit in Science Methods Courses

In this section, we describe examples of how the tools have been implemented within science methods courses at two different public universities. Each of these courses enrolls PSTs who are completing requirements to teach science at the secondary level (grades 6-12). The two scenarios demonstrate the flexibility of the tools as each instructor implemented them in different ways but with the same overarching goal of promoting PSTs’ discussion and understanding of three-dimensional lessons. (Note: some of the 3D Map samples differ in their labels from one another as they were used at different stages in the three-year process of designing the 3D Map).

Example 1: Starting with the 3D Map

This first example describes how the Next Gen ASET Toolkit was incorporated into a yearlong science methods course. The instructor had previously explored ways to incorporate the three dimensions of the NGSS into her course but reported that her students lacked the support to make connections across the dimensions, particularly within the context of a phenomenon. The course maintained its existing pedagogical strategies such as the 5E learning cycle, backward design, and science literacy approach (Bybee et al., 2006; Lee, Quinn, & Valdes, 2013; Wiggins & McTighe, 2001), but then focused the NGSS themed discussions via the toolkit. In this case, the instructor began with the 3D Map to frame the larger picture of the NGSS, and then introduced the SEP Tools later to explore the complexities of the practices within a three-dimensional context.

During the first few weeks of the course, the PSTs were introduced to the following overarching phenomenon: consider the yearly weather and temperature differences between two cities residing on the same latitude approximately 150 miles apart. One city is inland, the other on an ocean coast. The instructor then modeled lessons which could be used in a middle or high school classroom to explore this phenomenon.  Throughout this process, the instructor referred to a large, laminated version of the 3D Map. As the PSTs learned about the 3-dimensions of the NGSS (PEs, SEPs, DCIs, and CCCs), and related concepts of phenomena and essential questions, the instructor noted how these are integrated using the 3D Map. As new phenomena were introduced (such as ocean acidification), PSTs were challenged to add their own ideas of how model lessons incorporated components of the NGSS by gradually adding colored sticky notes into the related sections of the 3D Map on the wall (See Figure 3). This allowed PSTs to engage in making their own connections between sample activities and lessons modeled in the methods class to the boxes on the 3D Map. Throughout the course, PSTs continued to add other sticky notes to the 3D Map to illustrate the multiple layers and interconnectedness characteristic of a larger instructional segment aligned with the goals of the NGSS.

Figure 3 (Click on image to enlarge). Course example 1 classroom 3D map.

Using the 3D Map in this way was also beneficial in that it allowed the instructor to understand where her PSTs struggled with NGSS. For example, regarding the phenomenon of the two cities described above, the PSTs identified the following performance expectation as relevant: MS-ESS2-6. Develop and use a model to describe how unequal heating and rotation of the Earth cause patterns of atmospheric and oceanic circulation that determine regional climates. However, when pressed to modify their own statement of a phenomenon related to this instructional segment, the PSTs overwhelmingly responded with “properties of water.”  The instructor noted in her reflections with the research team how this demonstrated PSTs’ focus on content with little connection to the larger phenomenon intended. In addition, she cited that the PSTs struggled to indicate how the lessons engaged in specific components of a SEP including data collection, identifying patterns, creating flow charts as descriptions of energy flow, and identifying connections between climate and location of cities. Therefore, she found they required prompting in a more specific manner; this is where the SEP Tool for Analyzing and Interpreting Data became useful for focusing specific student actions aligned with unit objectives and therefore relevant assessments.

A unit plan was used as a culminating assessment for the PSTs to demonstrate their ability to utilize the tools. Teams used the 3D Map to plan an interdisciplinary unit related to climate change topics where specific data collection activities were highlighted with emphasis on the SEPs: Analyzing and Interpreting Data and Constructing Explanations.  For instance, one group designed a unit to investigate the phenomenon of coral bleaching (See Figure 4). As PSTs planned, they utilized the 3D Map to guide the structure of their unit: identifying a particular phenomenon, choosing relevant conceptual goals related to that phenomenon (e.g., ocean acidification, pH changes, carbon cycles, impact of acidification on shelf-forming animals), associated and bundled Performance Expectations; related SEPs that would support the concepts and phenomenon (e.g. collecting and analyzing data from live and archived online estuary stations); chose DCIs that integrated life and physical sciences (LS2.B: Cycle of Matter and Energy Transfer in Ecosystems; PS3.D: Energy in Chemical Processes and Everyday Life; LS2.C: Ecosystem Dynamics, Functioning, and Resilience) and applied appropriate, transcending connections found in at least one CCC (i.e. Cause and Effect) – all of which translated into various formative and summative assessment opportunities aligned to unit objectives.

Example 2: Starting with the SEP Tools

This second example describes how the Next Gen ASET Toolkit was incorporated into a 1-semester (16 weeks) science methods course. While the course had previously emphasized curricular methods that were hands-on and followed the inquiry approach to teaching science, inclusion of NGSS beyond simply stating the architecture, which provided a surface level introduction, had not yet happened. The course instructor decided to use the SEP Tools in class during the first few weeks to facilitate reflection and discussion, and then introduce the 3D Map later in the semester.

During the second week of class, PSTs engaged in a traditional lesson around scientific inquiry, working to construct a model of what might be happening inside an opaque box. During this lesson, the PSTs worked in small groups to investigate what was inside a given set of black plastic boxes. After completing the activity, the PSTs were given the SEP Tool for Constructing Explanations. They selected which of the subcategories this activity engaged them in and used this tool to guide discussion in small groups and then as a larger class. After using this SEP Tool, during the following class meeting PSTs were given a brief overview of the NGSS architecture and vision for connecting three dimensions in learning. Focus was given to the SEPs when first introducing the NGSS. It was also discussed how some of these traditional lessons around inquiry do not truly integrate elements of each dimension and how these might be modified to allow for exploration of a DCI using these SEPs.

In the following weeks the instructor went into more depth with these PSTs about the other dimensions of the NGSS as well as overarching instructional goals. During the eighth week of class PSTs were shown the 3D Map. At this point in the course they were familiar with the NGSS and its dimensions. They had also spent time learning about how to write learning objectives and instructional strategies in science aligned with inquiry methods.

At this point, the instructor spent two hours in class engaging the PSTs in a model lesson on genetics. The PSTs participated as the students would in the lesson. Groups of PSTs were given various family histories based on genetic counseling interviews. The PSTs were provided some instruction on how to construct a pedigree and then tasked to use the information provided about their given family and construct a pedigree to determine what information they would tell this family if they were a genetic counselor working with them. Within the context of the pedigree sample lesson, the SEP tool for Analyzing and Interpreting Data (see Figure 5 for example) was used to help guide discussion of what is considered data in science and how scientists work with data. The instructor first prompted the PSTs to read the subcomponents listed and indicate which of these they felt the lesson included, supported with evidence of these components in the lesson. The instructor pointed out multiple times that although each SEP had multiple subcomponents, the goal of a given lesson was not to include all of these but instead to practice and assess one or two of them.

After this discussion of the SEP, a laminated version of the 3D Map was revealed to the class. The instructor reviewed how each box on the map related to the NGSS or larger ideas around lesson planning in science. The PSTs were then given sticky notes (each group a different color) and told to use these to put their group’s ideas for each box onto the map. The instructor had put notes for the NGSS standards and PE to focus students’ time on discussion of how these were connected in the lesson as well as related ideas on the map.  At the end of this class period the laminated 3D Map was full of sticky notes indicating each group’s contribution by color (Figure 6).

The following class period, approximately 90 minutes were spent discussing the different groups’ responses on the 3D Map. Much of the discussion centered on the phenomenon, conceptual goals, and how the three dimensions of the NGSS were linked in the lessons (bottom row of boxes). The use of the 3D Map guided the PSTs to think about how different elements of the NGSS and lesson planning needed to be considered when planning instruction. While no “best response” was given by the end of the discussion, PSTs expressed consideration of how multiple ideas presented from the sticky notes might help connect dimensions as well as increased confidence in understanding the vision of designing lessons to explore content around a given phenomenon.

Following this discussion using sticky notes, the 3D Map was placed on the wall in the classroom and referred to as the class continued to explore exemplar lessons and dimensions of the NGSS. As in the first scenario, PSTs in this course completed a culminating assessment of a lesson sequence that included completion of a 3D Map. The PSTs in this course completed this assignment individually, with some time in class given to share ideas and critique phenomenon identified for their lessons.

In a written reflection at the end of the course, when asked about the experience of implementing the Next Gen ASET Toolkit, the second instructor reported:

“Before ASET, my approach to the NGSS was almost exclusively through my students engaging in the SEPs – basically, for me, equating having students engaged in learning through the SEPs was equivalent to engaging them in learning science through inquiry. […]  Having done the ASET ‘prompted’ explicit work introducing my students to the DCIs and CCCs, and continuing with the SEPs.  The use of the 3D map as an integral component of my culminating assignment has 1) Supported my own understanding of what 3D planning can really look like in actual classroom practice and thus 2) given me the confidence that using the ASET tools with my students will truly support their understanding of the NGSS and their implementation of authentic and engaging science lessons for their future students.”

This quote suggests that integrating the Next Gen ASET Toolkit into this course not only supported PSTs’ understanding of the NGSS, but supported the faculty instructor in making his own teaching strategies related to NGSS more explicit.

Discussion

While the two examples described start with the use of different tools, they each demonstrate the flexibility of these tools for their use with a variety of model lessons. The promotion of discourse was inherent in the purposeful design of the 3D Map and the SEP Tools. Without the visual scaffold and the ability to make notes on a large laminated 3D Map, or on large handouts in the methods classroom, the complex conversations around planning for the NGSS would be lost in a disconnected set of activities and course assignments.

In the first scenario, the larger vision of NGSS represented by the 3D Map was presented first and then followed with exploring the complexities of the practices through use of the SEP Tools. For instance, activities related to the ocean as a heat reservoir (activities and lessons including models of ocean currents, wind patterns, weather patterns, thermal expansion of water, etc.) initially were perceived by PSTs as isolated activities to illustrate a limited number of concepts. However, conversations guided by the 3D Map framed the phenomenon of temperature differences between a coastal and an inland city at the same latitude; PSTs began to understand the connections instruction should make to connect a series of lessons to support this phenomenon.

In the second scenario, focus was given to the complexity of the SEPs first and then expanded to the 3D Map, including the larger picture of how to align science instruction with the NGSS. In this case, the SEP Tools helped to demonstrate how the practices can be used in different ways depending on the lesson. For example, in the pedigree activity, at first many PSTs did not think of qualitative data as data that students would use for analysis. However, through their discussion, framed by the SEP Tool for Analyzing and Interpreting Data, PSTs were able to focus on the various ways that they engaged with data in this way.

The visual 3D Map and the SEP Tools allowed for discussion of the various ways to make these connections clearer, made assessment possibilities more salient, and reinforced the relationships between doing science (SEPs) and understanding the concepts (DCIs) through specific lenses that link the domains of science (CCCs) serving as ways to assess overarching connections related to a given phenomenon. As is demonstrated in the examples, the role of the instructor was essential to guide this discussion for PSTs. As the instructor highlighted essential elements and relationships on the tools, PSTs were supported to make connections between course activities and the vision of the NGSS. Previous attempts to make broad and unstructured connections between model lessons and the NGSS dimensions were not as successful for either instructor. The first instructor lacked the support to make these explicit connections and the second instructor had only made surface level connections to the architecture with no depth to the vision for instruction aligned to the NGSS.  Integration of these courses with the Next Gen ASET Tookit made elements, which had been implicit, much more explicit to PSTs. They provided the structure and support needed to prompt meaningful discussions with appropriate scaffolds.

The Next Gen ASET Toolkit is not meant to be separated into stand-alone tools but are meant to be used as part of a larger course that together with exemplar lessons and dialogue, support understanding of the complexity of planning for the NGSS, guided by the course instructor.  These tools should not simply be handed to an instructor without support since they may not know how to effectively integrate these tools to support discussion or themselves may be unprepared/untrained in how to align instruction to the NGSS.  The current website provides some support for implementing these tools. These limitations show the importance of using the Next Gen ASET Toolkit while also participating in discussion with other methods course instructors and other individuals who understand how to effectively align instruction to the NGSS.

Next Steps

This paper reports on the first three years of our five-year study as the Next Gen ASET Toolkit was developed and implemented.  The toolkit is currently being implemented in science methods courses across five of the original six university campuses.  The faculty member at the sixth campus, due to commitments on other projects, is not currently able to teach the methods course at the university.  Each of these courses includes a culminating activity for PSTs to generate a lesson sequence or unit plan, using the 3D Map to help guide the development. In each course, the SEP Tools and 3D Map are utilized to help promote and support discussion around the NGSS. Instructors from each campus meet via videoconference monthly and discuss the progress of instruction via use of the tools by sharing data collected on student artifacts and course activities. The project team is currently expanding this network to include more campuses to engage in research using these tools. This expansion includes exploring the use of these tools with inservice teachers as well as with university supervisors to support the reflective dialogue happening as they observe PSTs’ field-experiences.

The instructors currently implementing the Next Gen ASET Toolkit report that these tools assist their PSTs in developing lessons that integrate the three-dimensionality and complexity of the NGSS. During monthly videoconferences these instructors share results from their courses and suggestions for how to improve instruction. These instructors are also involved with considering any further improvements to the tools based on results from their use in the courses.  The toolkit shows promise to be an example of the tools that have been called for to assist PSTs in explicitly unpacking these standards and illuminate their underlying components (Krajcik, McNeill, & Reiser, 2008).

Conclusion

The university courses currently implementing the Next Gen ASET Toolkit are shifting instruction within methods courses to align their teacher preparation program to meet the vision of the Framework and the NGSS (NRC, 2012). Integration of these tools into a methods course alongside exemplar lessons allows for the instructor to make explicit connections to the NGSS. The 3D Map allows for a visual scaffold and dialogue of how the lesson or lesson sequence integrates dimensions of the NGSS. The 3D Map also allows PSTs to visualize the variety of components necessary to consider in creating effective lessons aligned to the NGSS. The SEP tools provide explicit ways for the instructor to convey the complexities of each of these practices as well as guiding PSTs to consider how they will best include these in their own lessons. While this toolkit is not meant to be used in isolation, when used to promote discussion and reflection alongside model lessons it has shown promise to allow instructors to shift their instruction to support students understanding of the NGSS.

Abstract

Two instructors in a secondary preservice teacher preparation program address the need to better prepare future teachers for the increasing role project-based learning has taken on in K-12 education. We describe an integrated instructional planning course where a mathematics educator and a science educator collaborated to teach preservice teachers how to design integrated project-based lessons. We found that the preservice teachers valued the integrated approach but had difficulty translating their learning to practice in traditional, clinical-based field placements. We report on recommendations for future course iterations.

Abstract

In this paper we describe a professional development project with secondary physics and physical science teachers. This professional development supported fifteen teachers in learning the newly adopted Next Generation Science Standards (NGSS) through integrating physical science content with engineering and engineering practices. Our professional development utilized best practices in both face-to-face and virtual meetings to engage teachers in learning, implementing, and reflecting on their practice through discussion, video sharing, and micro-teaching. This paper provides details of our approach, along with insights from the teacher participants. We also suggest improvements for future practice in professional development experiences similar to this one. This article may be of use to anyone in NGSS or NGSS-like states working with either pre- or in-service science teachers.

Abstract

The nature of science (NOS) has long been an essential part of science methods courses for elementary and secondary teachers. Consensus has grown among science educators and organizations that developing teacher candidate’s NOS knowledge should be one of the main objectives of science teaching and learning. Cobern and Loving’s (1998) Card Exchange is a method of introducing science teacher candidates to the NOS. Both elementary and secondary teacher candidates have enjoyed the activity and found it useful in addressing NOS - a topic they tend to avoid. However, the word usage and dense phrasing of NOS statements were an issue that caused the Card Exchange to less effective than intended. This article describes the integration of constructivist cross-curricular literacy strategies in the form of a NOS statement review based on Cobern and Loving’s Card Exchange statements. The use of literacy strategies transforms the Card Exchange into a more genuine, meaningful, student-centered activity to stimulate NOS discussions with teacher candidates.

Abstract

The Next Generation Science Standards present a bold vision for meaningful, quality science experiences for all students. Yet students with disabilities continue to underperform on standardized assessments while persons with disabilities remain underrepresented in science fields. Paramount among the factors contributing to this disparity is that science teachers are underprepared to teach students with disabilities while special education teachers are similarly ill-prepared to teach science. This situation creates a pedagogical and moral dilemma of placing teachers in classrooms without ample preparation, thereby guaranteeing attitudinal and practical barriers. To address this challenge, the authors of this manuscript developed a novel project in which, through voluntary participation, members of Ohio University’s National Science Teachers Association student chapter co-planned and co-taught inclusive science lessons with members of the university’s Student Council for Exceptional Children at the Ohio Valley Museum of Discovery, a local hands-on discovery museum. This manuscript describes the motivation for, methods, and findings from the project, as well as recommendations for other programs wishing to implement a similar model.

Introduction

The Next Generation Science Standards present a bold vision for equitable and excellent science opportunities through a call for “All Standards, All Students” (Next Generation Science Standards [NGSS] Lead States, 2013, Appendix D). Following in the footsteps of the earlier “Science for All” efforts, the NGSS articulate a range of supports for marginalized groups in science, including students with disabilities. For those of us who have worked on issues of science equity and accessibility throughout our careers, it seems implausible that profound educational disparities and attitudinal barriers persist in the 21st Century. Yet despite decades of work on inclusive science research and practice, persons with disabilities continue to be underrepresented in science careers while students with disabilities underperform on science assessments (National Assessment of Educational Progress [NAEP], National Center for Education Statistics [NCES], 2011; National Science Foundation [NSF], 2013). Paramount among the factors contributing to this disparity is that science teachers are underprepared to teach students with disabilities in their classrooms, while special education teachers are similarly ill-prepared to teach science ( Irving, Nti, & Johnson, 2007; Kahn & Lewis, 2014). An obvious solution is to have science and special educators co-teach in the classroom, yet research suggests that without preparation and experience in such models, teachers face tremendous obstacles including lack of co-planning time, challenges with establishing roles and responsibilities, and simply lack of familiarity with discipline-specific accommodations (Moin, Magiera, & Zigmond, 2009). This situation creates a pedagogical and, as we believe, a moral dilemma of placing teachers in classrooms without ample preparation, a set-up for attitudinal and practical barriers.

We were therefore interested in developing flexible opportunities for science teacher candidates to interact and co-teach with special education candidates in an effort to provide meaningful experiences for all of our students, contribute to the research base in inclusive science teacher education, and support our greater community. To that end, we developed an Inclusive Science Day during which members of our Ohio University National Science Teachers Association (OU-NSTA) student chapter co-planned and co-taught inclusive science lessons with student members of our Student Council for Exceptional Children (SCEC) at the Ohio Valley Museum of Discovery (OVMoD), a local hands-on discovery museum. In doing so, our candidates learned about inclusive science practices, experienced co-planning, budgeting, and delivering science activities for a diverse audience, gained appreciation for the benefits of informal science community partnerships, and learned about themselves as future teachers of all students. This manuscript describes the motivation for, methods, and findings from our project, as well as recommendations for other programs wishing to implement a similar model.

Theoretical and School Context

Teacher Preparation and Science for Students with Disabilities

The Individuals with Disabilities Education Act, later reauthorized as the IDEIA (2004), guarantees a free appropriate public education in the least restrictive environment. For the more than 6 million students in American schools identified as having disabilities, this means that they are guaranteed opportunities for learning commensurate with their abilities across subjects, including science. While most science teachers at all levels will teach students with disabilities in their classrooms, most receive little formal education in inclusive science practices. In their nationwide survey of 1088 science teachers, Kahn and Lewis (2014) found that, while 99% of the participants had taught students with disabilities during their careers, nearly one-third had not received any training on the subject and of those who had “on the job training” was cited as the most prominent context for learning. Similarly, special education teachers receive little training in science education (Patton, Palloway, & Cronin, 1990), leaving them to frequently be marginalized in inclusive science settings, with science teachers taking the lead. It is perhaps, therefore, not surprising that students with disabilities underperform on standardized science assessments and are underrepresented in science fields. Without the benefit of teachers who have been adequately prepared to develop accessible lessons using inclusive pedagogical approaches, students with disabilities will continue to be underserved in the sciences.

Although science and special education are often characterized as representing different philosophical stances (McGinnis & Kahn, 2014), contemporary frameworks like Universal Design for Learning (UDL; Meyer, Rose, & Gordon, 2015) can mediate these differences by capitalizing on the abilities and acknowledging the challenges of all students, thereby creating a cohesive approach to ensuring access for the greatest number of learners. We hypothesized that allowing candidates to co-plan and co-teach UDL activities would provide them with the unique opportunity to discover each other’s strengths, assess their own weaknesses, and become exposed to different perspectives. As in most teacher education programs, however, these opportunities were scant for our candidates due to the structural requirements of their different programs of study and teaching placements. It seemed that a less formal opportunity was needed to explore possible benefits and challenges of collaborative inclusive programming. We decided to turn to the OVMoD for assistance.

Informal Science Learning

Informal science learning spaces, such as museums, zoos, aquaria, botanical gardens, provide unique opportunities for contextualized science learning for their visitors (Bell, Lewenstein, Shouse, & Feder, 2009). By providing materials and exhibits that are not otherwise readily accessible, allowing for open, unstructured discovery, and welcoming learners of all ages and backgrounds, these spaces offer incomparable resources to their surrounding communities (Fenichel & Schweingruber, 2010). Informal science learning spaces also provide powerful contexts for learning, not only for visitors but also for teacher candidates (Duran, Ballone-Duran, Haney, & Beltyukova, 2009). By providing candidates with teaching opportunities in such spaces, candidates learn to “think on their feet” as they are met by learners about whom they have no prior information, and must therefore anticipate challenges and respond quickly. They are also exposed to visitors representing a variety of ages, backgrounds, and abilities, thus necessitating a true “science for all” attitude and approach (McGinnis, Hestness, Riedinger, Katz, Marbach-Ad, & Dai A., 2012). Finally, bringing teacher candidates to informal science learning spaces allows them to learn about and serve their community, and of course, allows the community to become better acquainted with the programs and services available through the university, thereby promoting symbiotic learning opportunities (Bevan et al., 2010).

Our Programs

The Patton College of Education at Ohio University serves approximately 1600 undergraduate and 900 graduate students and uses a clinical model for teacher preparation, thus ensuring extensive in-school opportunities for students beginning in their sophomore year and benefitting from close relationships with partner schools (National Council for Accreditation of Teacher Education, 2010). Within our Department of Teacher Education, undergraduate and masters students can select from a wide swath of science teaching majors leading to certification in middle and secondary science areas. In addition, we have a thriving early childhood program that includes courses in both preschool and elementary science methods. Likewise, our nationally-recognized special education program leads to multiple graduate and undergraduate licensures. Undergraduate licensures include programming for intervention specialists seeking degrees to work with students with mild-to-moderate or moderate-to-intensive educational needs.

As vigorous and comprehensive as our programs are, teacher candidates from science education and special education interact infrequently during school hours due to their divergent course and placement requirements. Fortunately, our college supports (both philosophically and financially) our professional organization student chapters which afford opportunities for flexible collaboration. Our Ohio University National Science Teachers Association (OU-NSTA) student chapter welcomes all students with an interest in science teaching and learning. This chapter experienced a renaissance recently with regular meetings, numerous fundraising activities, learning opportunities including attendance at a regional NSTA conference, and a concerted commitment to service learning in our community. This chapter currently has approximately 25 members representing both undergraduate and graduate programs, although most are undergraduate secondary (middle and high school) science education majors. Our Student Council for Exceptional Children (SCEC) boasts a large, consistent membership of approximately 35 to 40 teacher candidates who meet regularly, assist with functions held by the local developmental disabilities programs, and provide fundraising support for members of the community with disabilities as well as schools in need of resources for serving students with disabilities. This organization enjoys the leadership of a long-term and beloved advisor who has developed the group through many years of mentoring and modeling. In addition to our college of education, our university’s center for community engagement provides small grants for service learning projects. We were fortunate to receive funding for our Inclusive Science Day project to cover the cost of training materials used with our teacher candidates, consumables for science activities, and refreshments. In addition, this grant provided funds for two of our students to attend a regional NSTA conference early in the year at which they interviewed various leaders in the science education community as well as publishers and science education suppliers about their inclusive science materials. This experience was eye-opening for our students, who presented their findings at subsequent group meetings, as it set the stage for our Inclusive Science Day planning.

The Intervention: Inclusive Science Day

In order to determine the potential for an Inclusive Science Day at an informal learning space, the OU-NSTA advisor raised the idea with a colleague from the College of Education, who is also on the board of the OVMoD to discuss possibilities. The colleague indicated that the museum had made concerted efforts to reach out to visitors with all abilities through use of universally-designed displays and a “sensory-friendly” day; she was completely open to the idea of having teacher candidates plan and teach at the museum but would need to discuss the idea with the museum’s executive director and other board members.  The OU-NSTA advisor then met with the SCEC advisor, who was equally enthusiastic about the prospect of collaboration. Both the OU-NSTA and SCEC advisors then presented the idea to their respective executive board members who were highly receptive. Concurrently, the OU-NSTA advisor participated in an 8-week course on service learning offered by the university’s center for community engagement in order to better understand the dynamics of collaborative endeavors with community entities and to consider in depth both the potential learning opportunities for the teacher candidates and the service opportunities for the museum. While it might have been possible for this project to come to fruition without that training, the advisor felt that it undoubtedly prepared her for the potential benefits and challenges. Once all parties embraced Inclusive Science Day, the two advisors began to plan the training and research.

Planning and Orientation

One of the most daunting tasks was simply identifying a day/time that students could meet for an orientation and training. As this was a voluntary endeavor, we knew that we would need to ensure that our meetings were highly efficient, focused, and would inspire our teacher candidates to collaborate on their own time to ensure availability and convenience. Once we had an announced orientation time, the two advisors met to plan the training. We determined that the 2 1/2-hour evening training would include the following agenda:

  • Welcome, Refreshments, and Survey Invitation
  • Why Inclusive Science Day? and “Can You Name This Scientist?”
  • Collaborative Hands-on Simulation Activity (“Helicopters”) and Debriefing UDL
  • Lesson Planning and Budgeting Activities
  • Next Steps!

As we had decided to conduct research on teacher candidates’ experiences and attitudes regarding inclusive science practice, we applied for and received IRB approval for a pre and post survey that was distributed anonymously online at the orientation (pre) and after the Inclusive Science Day (post). Students were recruited for the Inclusive Science Day and associated research via e-invitations sent to organization membership lists in advance of the orientation. Because of our desire to avoid exerting pressure on students to participate in either the research or project, we did not require students to RSVP. We were very pleased to see that 18 students attended the training (ten special education and eight science education, including one elementary science methods student). When the students arrived at the orientation, they created nametags, had the opportunity to complete the survey online, and enjoyed pizza. We then distributed students among five tables so that at least one special education candidate was at each table. After introductions, we engaged in a brief brainstorming challenge to identify why inclusive science education might be important.  Candidates actively identified reasons including:

“There aren’t enough scientists with disabilities in the field.”

“Science is part of every child’s life and body.”

“You can teach science through different in different ways (e.g., visual, tactile, kinesthetic, etc…).”

“Knowing about science is important for everyone!”

“We need to know how to teach all students.”

We added three others to the list that students did not mention:

  • Science benefits from having all students contribute to its advancement.
  • There is a moral imperative for all students to have the opportunity to experience science.
  • Science is beautiful!

We then engaged in a “Can You Name This Scientist?” game in which candidates viewed pictures of famous scientists with disabilities and were asked to identify them.  Scientists included Alexander Graham Bell (Dyslexia), Thomas Edison (Hearing Impairment and Dyslexia), Temple Grandin (Autism), Geerat Vermeij (Visual Impairment), Jack Horner (Dyslexia), and Stephen Hawking (Motor Neuron Disease), among others. Most of our candidates were unaware that such accomplished scientists also had disabilities and that their disabilities, in some cases, may have enhanced the scientists’ interests and abilities in their fields. For example, Geerat Vermeij, a world-renowned paleobiologist attributes his nuanced abilities in identifying mollusks to his ability to feel and attend to distinctions in shells that sighted scientists might overlook (Vermeij, 1997). We were excited to see our students’ interests so piqued after this activity.

We then introduced the Universal Design for Learning (UDL; Meyer, Rose, & Gordon, 2014) framework, which allows teachers to develop lessons that meet the needs of the most number of learners thereby reducing the need for specific disability accommodations. The three principles of UDL are: 1) Multiple Means of Engagement (How students access the lesson or materials); 2) Multiple Means of Representation (How teachers present the material to the students); and 3) Multiple Means of Action and Expression (How students interact with the materials and show what they know). To help teacher candidates to better understand the potential barriers that students with disabilities might have in science class, we co-led a science activity in which students followed written directions for making and testing paper helicopters while assigning students equipment that helped them to simulate various disabilities. For example, some students received handouts that had scrambled letters to simulate Dyslexia, while others wore glasses that limited their vision. In addition, some students wore earplugs to simulate hearing impairments while others listened to conversations on headphones to simulate psychiatric disorders. Finally, some students had tape placed around adjacent fingers to simulate fine motor impairments, while others utilized crutches or wheel chairs. Students progressed through this activity for several minutes and then discussed their challenges as a class. We chose the helicopter activity because it required reading, cutting with scissors, throwing and observing the helicopters, and retrieving them; thus, this activity required a variety of intellectual and physical skills. We found that our students were quite impacted by this activity, as many indicated that they had never really thought about the perspective of students with these disabilities. In particular, the student who utilized a wheelchair said that she had never realized how much space was needed to accommodate the wheelchair easily during an active investigation. This led the group to discuss the need for us to set up our tables at the museum with sufficient space for all visitors to comfortably traverse the museum. Of course, we were careful to remind students that this type of simulation cannot accurately represent the true nature and complexity of anyone’s experiences, and that people with disabilities, like all individuals, develop adaptations for addressing challenges. However, this brief experience prompted our students to think about how they could redesign the lesson to ensure that as many students as possible could access it without specific accommodations.

We then informed the groups that they were each to develop plans for two activities that would be presented at the Inclusive Science Day. Based on discussions with museum administrators, we decided that having several “make and take” activities was desirable, in part because it allowed the learning to continue at home, but also because our university is in a very rural, high poverty region thus making these types of materials a particularly welcome benefit for many families (United States Census Bureau, 2014). Together, we reviewed the lesson plan document which was less formal than our typical lesson plan document (due to the informal nature of the museum activity stations format) but nevertheless, had specific learning outcomes, considerations for diversity (including gender, socioeconomic status, English language proficiency, and ability), and a budget (See Figure 1 for a Sample Lesson; a blank lesson plan template is available for download at the end of this article in supplemental materials). We then informed teams that, thanks to the grant we had received, they had $50 to spend on their two lessons and that they should anticipate approximately 50 visitors to their tables (based on prior museum visitation counts). Teacher candidates then used their laptops and various resource books we provided to identify activities and develop materials lists with prices. We decided the easiest way to ensure that all materials would be received in time, and to avoid dealing with reimbursements and other financial complexities was to have students submit their final budget sheets to us during the week following the orientation. We would then order all the materials using one account and notify students once the materials were received. Students were responsible for bringing in “freebie” materials such as newspaper, aluminum cans, matches, etc. Once materials were received, student groups came to the central storage room at their convenience to check and prepare their materials in ample time for the program. We also encouraged students to create table signs for display at the Inclusive Science Day. They did this on their own time as well. Some of the activities that students developed were:

  • Fingerprint Detectives
  • Creating a Galaxy in a Jar
  • Chemical Reactions in a Pan (using baking soda and vinegar mixed with food coloring)
  • Exploring Static Electricity with Balloons
  • Egg Drop
  • Making and Testing Kazoos
  • Blobs in a Bottle (with vegetable oil and Alka-Seltzer tablets)
  • Inflate a Balloon Using Chemistry
Figure 1 (Click on image to enlarge). Sample lesson plan for “Inflate a Balloon Using Chemistry.”

In addition to identifying activities that engaged different senses, our students thought about how to meet a variety of learners’ needs. For example, magnifiers and large ink stamp pads would be available at the fingerprint station for all students, while the “Blobs in a Bottle” activity station had alternative “jelly balls” that could be felt by visitors who couldn’t see the vegetable oil “blobs.” The kazoo station, which used toilet paper tubes, waxed paper, and rubber bands, allowed visitors who could not hear to feel the movement of the waxed paper when the kazoos were played. The station also had adaptive scissors and pre-cut waxed paper for visitors needing fine motor skill support. The UDL considerations and accommodations provided for each activity are contained in Table 1 below.

UDL Considerations and Accommodations for Accessibility on Inclusive Science Day

The Day of the Event

The Inclusive Science Day was announced by the museum on social media, through our local schools, and through the local newspaper. The museum generously waived their admission fee for the day in order to encourage attendance as well. On the day of the program, students were asked to arrive two hours in advance to set up their stations. We provided lunch to ensure that we had time to speak to the group about the importance of the work they were about to do, and to allow the museum staff to convey any final instructions to the students. When the doors were opened, we were thrilled to see large numbers of families entering the museum space. Over the two hours that our program ran, the museum estimated that we had over 150 visitors, approximately three times their expected attendance. The attendance was so good that some of our student groups needed to send “runners” out to purchase additional materials; our “Galaxy in a Jar” group even began using recycled bottles from our lunch to meet the demands at their table.  Safety was a consideration at all times. Goggles were made available at all tables with splash potential, and safety scissors were used at stations with cutting requirements. In addition, our students (and we) wore our clubs’ T-shirts so that visitors could easily identify instructors. Each activity table had at least one science education and one special education candidate co-teaching. We supervised the students by assisting in crowd control, helping to ensure that visitors could easily navigate through the rather limited museum space, obtaining written permissions for photos from parents/caregivers, and responding to candidate questions. Some photos from the day are shown in Figures 2-4.

Research Findings/Project Evaluation

Overall, our teacher candidates found this project to be highly meaningful and helpful for their professional learning. Perhaps one of the most important themes that emerged from our evaluative research was that science and special education candidates welcomed the opportunity to collaborate as none of them had reported having opportunities to do so in the past. Some of the student post-activity responses included the following:

“[Inclusive Science Day] allowed me to gain more experience and to really learn what it is like to teach students who have disabilities. I also was able to see how students with different disabilities reacted to the same activity. I found that those students who had a disability found a different way to cope with their disability than we had thought they would.”

“I saw how different general education and special education teacher think. There were many differences to our approaches to creating the lesson.”

“I really liked that I was able to consult with the special education teachers if I was unsure of how to help a student with disabilities.”

“I had a great time sharing my content knowledge of science with those whose specialty is special education. Conversely, I had a great time learning from experts in special education and I really enjoyed seeing them be so in their comfort zone when we did have kids with exceptionalities. I envy their comfort levels and it makes me want to reach that level of comfort.”

“We were well prepared for any differentiation that would have needed to be done. And we all learned from each other.”

“I feel this was an awesome experience. The people I worked with really added something to our experiments that I otherwise may not have thought about.”

Challenges cited by our students included feeling a bit overwhelmed by the number of visitors at each station, not having knowledge about the visitors’ backgrounds in advance, and difficulties in maintaining visitors’ focus on the science content. We found one student’s reflection to be quite sophisticated in its recognition of the need for more training on inclusive science:

“I still feel that I would like more professional development when it comes to leading science activities for students with disabilities. I had an experience with a wonderful young man and I felt very challenged because I don’t feel comfortable enough to gauge what I should be allowing him to do on his own and at the same time I didn’t want to hinder him from reaching his full potential. So, I feel like further professional development in that area is needed for me.”

Qualitative  analysis of candidate pre and post responses resulted in themes that included: 1) candidates’ assessment of collaboration as a powerful professional development opportunity; 2) identification of different perspectives between science and special education candidates; 3) a common desire to do good work by making accessible for all students; 4) recognition of informal learning spaces as viable teaching venues; and; 4) a strong need for more training and opportunities to teach science to students with disabilities. Our findings support earlier research suggesting that teacher candidates are inclined toward inclusive practices (McGinnis, 2003) and that opportunities for collaboration with special education candidates enhance their comfort level in co-planning and co-teaching (Moorehead & Grillo, 2013). Our teacher candidates’ expressions of the depth of impact this professional development experience had on them makes sense when considered in light of Kahn and Lewis’ (2014) study which suggested that teachers’ experience with any students with disabilities increased their feelings of preparedness toward working with all students with disabilities. In addition, our findings reinforce studies suggesting that informal learning spaces can provide unique and flexible learning opportunities for teacher candidates, particularly in that they provided multiple opportunities to teach the same lesson repeatedly, thus allowing for reflection and revision (Jung & Tonso, 2006). Perhaps most importantly, this study underscores the desire for and efficacy of increased training and experience in implementing inclusive science practices during teachers’ pre-service educations.

Future Plans and Conclusion

Based on the feedback from the teacher candidates and the museum, we are planning to make Inclusive Science Day an annual event. However, we are considering several changes for future projects including:

  • Multiple training evenings for teacher candidates
  • Pre-registration for Inclusive Science Day so that we can anticipate attendance size and specific needs of visitors
  • Creating a “Quiet Zone” area at the museum for visitors who would benefit from a less bustling environment
  • Identifying additional sources of funding for consumable materials
  • Greater outreach to our early childhood teacher candidates to encourage participation

As students with disabilities are increasingly included in science classrooms, it is incumbent of teacher education programs to ensure that their science teacher candidates acquire the tools and the dispositions for teaching all learners. While more formal approaches, such as dual licensure programs and co-teaching internship placements are on the horizon for many programs, teacher education programs should not overlook the power of extracurricular events, informal learning spaces, and student organizations to provide important professional development opportunities for teacher candidates, pilots for new program development, and occasions to both serve and learn from the community.

Abstract

Podcasts (like “You are Not So Smart”, “99% Invisible”, or “Radiolab”) are becoming a popular way to communicate about science. Podcasts often use personal stories to connect with listeners and engage empathy, which can be a key ingredient in communicating about science effectively. Why not have your students create their own podcasts? Personal science stories can be useful to students as they try to connect abstract science concepts with real life. These kinds of stories can also help pre-service elementary or secondary teachers as they work towards understanding how to connect science concepts, real life, and literacy. Podcasts can be powerful in teaching academic language in science because through producing a podcast, the student must write, speak, and listen, and think about how science is communicated. This paper describes the personal science podcast assignment that I have been using in my methods courses, including the literature base supporting it and the steps I take to support my teacher candidates in developing, writing, and sharing their own science story podcasts.
