Professional growth in adaptive teaching competence as a result of Lesson Study

Since classrooms have become more diverse, professional development on adaptive teaching seems critically important, yet turns out to be complex. Lesson Study may address this issue due to its explicit focus on student learning. In total, 22 Lesson Study participants from different school contexts were interviewed. Clarke and Hollingsworth's Interconnected Model of Professional Growth was used as the analyzing framework to explore its adequacy for understanding teacher professional growth. The results reveal teacher professional growth in adaptive teaching competence and show how the intensive focus on student learning, collaborative professional experimentation and the facilitators' role may contribute to this.
