Collaborative physics teachers: Enhancing the use of the laboratory through action research in a community of learners

This study contributes to the literature on the role of communities of learners in the professional development of physics teachers. It offers insights from the Collabora - A Community of Learners on Laboratory Work program, designed to enhance the use of laboratories in secondary school physics teaching. The program's foundation rested upon two pillars: a learning community approach and action research, grounded in the findings of physics education research. Furthermore, the program was structured to encompass the core features of effective professional development as outlined in the literature (content focus, active learning opportunities, coherence with teachers' needs, and sufficient duration). The program spanned 2 years. During the first year, teachers engaged with and discussed different types of experiments, reflected on the assessment of scientific practices, and participated in action research aimed at improving laboratory activities in their classrooms. In the second year, t...
