Inquiry-Based Professional Development: What does it take to support teachers in learning about inquiry and nature of science?

Abstract

This study examined the geologic and evolutionary subject matter and views of inquiry and nature of science (NOS) of a group of 5th–9th grade teachers, and a comparison group, before and after participating in an inquiry-based professional development (PD) experience. Project teachers participated in an intensive, week-long, resident institute where they learned about geology, evolutionary concepts, NOS, and inquiry while engaging in an authentic scientific investigation. They were also given support in how to teach these topics using an inquiry-based approach. Analyses of data indicate that project teachers showed greater gains in subject matter than comparison teachers and the relative change was significantly different statistically. Furthermore, most project teachers demonstrated a shift from less informed to more informed views of inquiry and NOS and the relative change between participant and comparison teachers was significantly different statistically. These gains are promising because they suggest that short-term and intensive PD can support teachers in enhancing their knowledge and views. Moreover, analysis of post-programme questionnaires and interviews indicated that supporting teachers in reflecting on the relationship between their former classroom teaching practice, and new knowledge acquired during PD, may be an important link in enhancing teacher knowledge and supporting change in practice. This suggests that enhanced knowledge and views may not be the only factor contributing to changing one's practice. The study points to the importance of reflection in promoting teacher change. Results from this study add insights to supporting teachers in enacting inquiry-based instruction and teaching about NOS in their classrooms.
