This article focuses on aspects of the Japanese Lesson Study method as well as professional development for teachers. Lesson Study is a professional teacher development model that aims to improve the teaching and learning process. Based on the practice of lesson study, this paper proposes a model for developing pedagogical knowledge and improving teaching. Recent research has suggested that effective professional learning would last forever. This necessitates a daily examination of the teachers. It is becoming increasingly important for teachers to mutually observe and jointly reflect on classroom practices in order to develop such a community.
