Instructional Pathways to Considering Social Dimensions Within Socioscientific Issues

by Rebecca Rawson Lesnefsky, University of North Carolina – Chapel Hill; Troy Sadler, University of North Carolina; Li Ke, University of Nevada-Reno; & Pat Friedrichsen, University of Missouri
Abstract

The Socioscientific Issues Teaching and Learning (SSI-TL) framework is a guide for developing an instructional approach to learning experiences focused on socioscientific issues (SSI). Despite the potential benefits of SSI learning, teachers often struggle to implement this approach in their classrooms (Sadler et al., 2006; Saunders & Rennie, 2013), and one of the most prominent reasons for this struggle is science teacher concerns and hesitation associated with incorporating social dimensions of the issues into their instruction (Friedrichsen et al., 2021). The purpose of this article is to provide science teacher educators with tools to help teachers better manage the integration of the social dimensions of SSI in issues-based teaching. In doing so, we suggest an expansion of the SSI-TL framework such that it more explicitly highlights pathways for focusing on the social dimensions of SSI within science learning environments. These pathways emerged as a result of a joint effort with nine high school science teachers as they developed a unit related to COVID-19; however, the pathways support science teachers as they implement science learning experiences that provide opportunities to negotiate social dimensions across most SSI. The pathways include systems mapping, connecting analysis to policy positions, media literacy, and social justice. We present how following each pathway integrates the social dimension of the focal issue, an example from the COVID-19 unit, evidence of success, and future considerations for science teacher educators as they help classroom teachers adopt an SSI approach.

Preparing Preservice Teachers to Help Elementary Students Develop Persuasive Science Writing

by Keri-Anne Croce, Towson University; & Lucy Spence, University of South Carolina
Abstract

To inspire change in the world, scientists must be agile communicators who can persuade different audiences around the globe. Persuasive science writing must reflect an understanding of how culture and language influence audiences in different ways. Examples of scientific writing designed for different audiences around the globe include pamphlets describing safe masking practices or public-service announcements about climate change. Preservice teachers must prepare the next generations of scientists to think of science content in conjunction with communication. This has created a high demand for university programs to prepare preservice teachers to teach elementary students how to create persuasive science writing. The International Science Text Analysis Protocols (ISTAP) teaching methodology was designed to help preservice teachers guide elementary students to develop tools for creating persuasive science writing. This article details how university programs may use ISTAP to support preservice teachers before, during, and after school placements. As linguistic and cultural diversity within science classrooms in the United States continues to expand, students will bring diverse resources into conversations centering on persuasive science writing. As university faculty guide preservice teachers through ISTAP, they are emphasizing diversity within science classrooms and supporting equity within STEM.

From Pandemic Pivot to Community Outreach: Homeschool Students as Participants for Course-Based Field Placements

by Ronald S. Hermann, Towson University; & Maureen G. Honeychuck, Towson University
Abstract

The Covid-19 pandemic resulted in a pivot to online instruction for our university and the surrounding K–12 schools. The instructors of the Classroom Interactions course faced the challenge of developing an online version of a course we had never taught that included a class-based field experience. During the fall semester, we struggled to recruit secondary students to participate in preservice teacher (PST) lessons, so we invited homeschool students to participate in the spring semester. This article outlines our approach to inviting homeschool students to participate in online PST-developed lessons. We outline our approach to utilizing the 5 Practices for Orchestrating Task-Based Discussions in Science (Cartier et al., 2013) to develop lessons, and we share PST and parent feedback on the experience. Additionally, we share the lessons we learned from this experience and suggestions for other teacher educators who may be interested in inviting homeschool students to participate in PST-developed field experiences. PSTs were able to focus on their lesson objective, instruction, and discourse moves for leading productive discussions because the PSTs and students did not experience many of the typical classroom distractions or behavioral issues that can occur during in-person learning in a school setting. Teacher educators interested in having more autonomy and input into how course-based field placements are implemented are encouraged to explore options to include homeschool students in-person or virtually.

Is This an Authentic Engineering Activity? Resources for Addressing the Nature of Engineering With Teachers

by Jacob Pleasants, University of Oklahoma
Abstract

Including engineering as part of K–12 science instruction has many potential benefits for students, but achieving those benefits depends on having classroom teachers who are well prepared to effectively implement engineering instruction. Science teacher educators, therefore, have an essential role to play in ensuring that engineering is incorporated into science instruction in productive ways. An important component of that work is developing teachers’ understanding of the nature of engineering: what engineering is, what engineers do, and how engineering is both related to yet separate from science. Teachers must understand these concepts to implement engineering design activities that authentically reflect the field. In this article, I describe a sequence of instructional activities designed to help teachers, either preservice or inservice, develop their knowledge of the nature of engineering. At the core of the instructional sequence is a set of stories that provide teachers with descriptions of authentic engineering work. Surrounding the stories are activities that help teachers draw accurate conclusions about the nature of engineering and draw out the implications of those conclusions for instructional decision-making. I provide an overview of the instructional sequence and also share details from my own work with teachers, including transcripts of classroom conversations and the impact of instruction on teachers’ knowledge.

A Sociotechnical Approach to Engineering Education: Engineering Social Justice for Elementary Preservice Teachers

by David Kimori, Minnesota State University, Mankato; & Charlene Ellingson, Minnesota State University, Mankato
Abstract

In this article, we describe an assignment that we have developed in our Engineering for Elementary Teachers course. The assignment was designed to address social justice within the engineering design process. In this course, preservice teachers (PSTs) develop an engineering project that integrates six criteria of engineering for social justice into their lesson plan as a way to make the social relevance of engineering more apparent. Beyond having teachers develop an engineering lesson plan, the goal is to increase awareness of the social justice dimension of engineering as a strategy for integrating culturally relevant pedagogies into engineering lessons. In this article, we share several lessons our PSTs have developed as well as insights that they gained about the relationship between engineering and social justice. We also share some of the challenges that the PSTs faced and the insights that we gained about integrating social justice criteria into engineering lessons.

Addressing Social Justice in the Science Methods Classroom through Critical Literacy: Engaging Preservice Teachers in Uncomfortable Discussions

by Nazan U. Bautista, Miami University; & Katherine E. Batchelor, Miami University
Abstract

The purpose of this paper is to exemplify how teacher candidates can be engaged in discussions around social justice and equity in science methods courses while also learning about and practicing essential science teaching strategies and skills. Our aim is that science teacher educators who do not feel confident enough to explicitly address these important issues in methods courses are encouraged to think creatively about how they can modify or alter their current practices in a way to prepare science teachers for the changing demographics of science classrooms. We present an engineering design activity that is coupled with critical literacy skills, called ‘Build a Child.” Upon identifying the problem, we introduce the context of the preservice teachers’ science methods course and reason for this work, followed by defining critical literacy and how it pairs well in science education. We then share the “Build a Child” engineering project and how we asked preservice teachers to critique and reflect on their creations, thus bringing in a critical literacy framework to the curriculum. Next, we share three findings based on our data analysis, and we end with the importance of science methods courses implementing social justice education and suggestions on how to reexamine our science curriculum to make it more culturally relevant and equitable for all students.

A 20-year Journey in Elementary and Early Childhood Science and Engineering Education: A Cycle of Reflection, Refinement, and Redesign

by Cody Sandifer, Towson University; Pamela S. Lottero-Perdue, Towson University; & Rommel J. Miranda, Towson University
Abstract

Over the past two decades, science and engineering education faculty at Towson University have implemented a number of course innovations in our elementary and early childhood education content, internship, and methods courses. The purposes of this paper are to: (1) describe these innovations so that faculty looking to make similar changes might discover activities or instructional approaches to adapt for use at their own institutions and (2) provide a comprehensive list of lessons learned so that others can share in our successes and avoid our mistakes. The innovations in our content courses can be categorized as changes to our inquiry approach, the addition of new out-of-class activities and projects, and the introduction of engineering design challenges. The innovations in our internship and methods courses consist of a broad array of improvements, including supporting consistency across course sections, having current interns generate advice documents for future interns, switching focus to the NGSS science and engineering practices (and modifying them, if necessary, for early childhood), and creating new field placement lessons.

Introducing Preservice Science Teachers to Computer Science Concepts and Instruction Using Pseudocode

by Kayla Brauer, Drake University; Jerrid Kruse, Drake University; & David Lauer, Drake University
Abstract

Preservice science teachers are often asked to teach STEM content. While coding is one of the more popular aspects of the technology portion of STEM, many preservice science teachers are not prepared to authentically engage students in this content due to their lack of experience with coding. In an effort to remedy this situation, this article outlines an activity we developed to introduce preservice science teachers to computer science concepts such as pseudocode, looping, algorithms, conditional statements, problem decomposition, and debugging. The activity and discussion also support preservice teachers in developing pedagogical acumen for engaging K-12 students with computer science concepts. Examples of preservice science teachers’ work illustrate their engagement and struggles with the ideas and anecdotes provide insight into how the preservice science teachers practiced teaching computer science concepts with 6th grade science students. Explicit connections to the Next Generation Science Standards are made to illustrate how computer science lessons within a STEM course might be used to meet Engineering, Technology, and Application of Science standards within the NGSS.

A Framework for Science Exploration: Examining Successes and Challenges for Preservice Teachers

by Keri-Anne Croce, Towson University
Abstract

Undergraduate preservice teachers examined the Science Texts Analysis Model during a university course. The Science Texts Analysis Model is designed to support teachers as they help students prepare to engage with the arguments in science texts. The preservice teachers received instruction during class time on campus before employing the model when teaching science to elementary and middle school students in Baltimore city. This article describes how the preservice teachers applied their knowledge of the Science Texts Analysis Model within this real world context. Preservice teachers’ reactions to the methodology are examined in order to provide recommendations for future college courses.

Introducing the NGSS in Preservice Teacher Education

by Tiffany Hill, Emporia State University; Jeni Davis, Salisbury University; Morgan Presley, Ozarks Technical Community College; & Deborah Hanuscin, Western Washington University
Abstract

While research has offered recommendations for supporting inservice teachers in learning to implement the NGSS, the literature provides fewer insights into supporting preservice teachers in this endeavor. In this article, we address this gap by sharing our collective wisdom generated through designing and implementing learning experiences in our methods courses. Through personal vignettes and sharing of instructional plans with the science teacher education community, we hope to contribute to the professional knowledge base and better understand what is both critical and possible for preservice teachers to learn about the NGSS.
