Teacher professional development (TPD) programs are increasingly using video recordings of teaching practice to develop teacher capacity and foster student learning. However, consensus has yet to be reached about how to utilize video recordings in TPD for physical education (PE) teachers. We used semi-structured interviews and evaluations of PE teachers' written reflective statements to investigate how they reacted as they engaged with different video material and external facilitators during a TPD program. Teachers believed video-based reflection on their own teaching, rather than viewing others' practice, was the most useful, even though both forms of analysis produced a similar depth of reflection. PE teachers also benefited from dialogue with external facilitators during the TPD program. These results highlight the importance of researchers, teachers, and facilitators delivering and participating in TPD collaboratively and focusing on strategies that may increase the depth of teacher reflection on their own practices, which is considered a first step toward changing classroom practice and improving student outcomes.
