Although most teachers recognize the importance of taking investigative, open-ended approaches to students’ learning experiences, implementing them in high school classes can be challenging for teachers. In this work, we analyzed data from multiple sources from a teaching Community of Practice (CoP) to investigate (a) barriers to taking an open-ended approach in teaching labs in physics classes, (b) shifts in teachers’ beliefs about taking an open-ended approach during their engagement in a physics teaching CoP in a partnership program, and (c) a case study of one teacher whose shifts in perceptions about taking an open-ended approach in teaching labs led to her successful implementation in her class. The findings confirm the existence of well-known psychological and structural barriers that can prevent teachers from adopting investigative approaches in teaching physics labs. Moreover, we learned how the interaction of these barriers further complicates the adoption of open-ended approaches in physics classes. The study also revealed a significant gap between teachers’ current practices and their desired methods of conducting labs, particularly in terms of structured versus open-ended approaches. The case study offered deeper insights into how shifts in teaching practices occur through changes in perceptions within a supportive CoP. 

By taking a responsive approach to the design and enactment of teacher professional development (PD), PD instruction can be tailored to teachers’ needs, interests, and concerns. This is of considerable importance in the high school physics teacher PD space, wherein teacher needs turn out to be particularly complex and diverse due to differences in teacher preparation within the discipline. More generally, understanding the degree to which PD programs are responsive to their teachers’ needs can support increased responsiveness. To this end, having a validated survey can assist in measuring the criteria for this responsiveness. This study presents the initial development of a responsive professional development (RPD) survey based on interviews with 13 high school physics teachers. Nine responsive codes were identified through thematic analysis of teacher interviews, and the resulting survey has been administered to 33 teachers for piloting purposes. In this work, the initial survey development process is presented.
