Rigorous Investigations of Relevant Issues: A Professional Development Program for Supporting Teacher Design of Socio-Scientific Issue Units

Socio-scientific issues (SSI) are complex problems with unclear solutions that have ties to science concepts and societal ideas. These complexities make SSI ideal contexts for meaningful science teaching and learning. Although the student benefits of SSI in the classroom have been established, there is a literature gap pertaining to teacher preparation and support for SSI teaching and learning, and the design of SSI units. In order for successful and meaningful SSI incorporation in science classrooms, teachers need professional development (PD) experiences that scaffold their understanding of the complexities associated with SSI teaching and learning. As such, our team designed and implemented a PD program with explicit examples and design tools to support teachers as they engaged in learning about SSI teaching and learning. Additionally, our PD program supported teachers as they designed their own SSI units for classroom implementation. We describe our PD process for supporting in-service secondary biology, chemistry, and environmental science teachers as they learned about SSI instruction and co-designed their SSI units.

Before our work with this group of teachers began, our research team designed and implemented SSI units, and these results informed development of the SSI-TL framework. The SSI-TL framework has been helpful as we continue to design and structure new SSI units, so we made it a central aspect of the PD to guide what SSI teaching should entail. This framework and other tools were used to support teachers as they designed their own SSI units. The PD was successful in that all groups designed SSI units, and many were able to implement in their classes. The teachers indicated the PD was effective from their perspective and they learned about issues and practices. Specific feedback around scaffolding tools we provided indicated the tools helped teachers navigate the design process.

A Blended Professional Development Model for Teachers to Learn, Implement, and Reflect on NGSS Practices

by Emily A. Dare, Michigan Technological University; Joshua A. Ellis, Michigan Technological University; & Jennie L. Tyrrell, Michigan Technological University

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.

Cobern and Loving’s Card Exchange Revisited: Using Literacy Strategies to Support and Enhance Teacher Candidates’ Understanding of NOS

by Franklin S. Allaire, University of Houston-Downtown

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.
