**Overview**

Lesson Study is a well-known approach originated from Japan for action research in the classroom by teachers. It is an effective model for teachers to join their activities to improve their teaching. This approach emphasizes the improvement of students’ mathematical thinking which involves three steps namely Plan-Do-See.

In this course, participants will have the opportunity to conduct lesson study in school collaboratively by practising the plan-do-see steps.

- Plan: Participants and facilitators work collaboratively to develop lesson plan;
- Do: A model teacher implements the lesson plan in a real classroom while others (teachers, headmaster, and facilitators) observes the lesson; and
- See: The teacher and observers conduct lesson evaluation and reflection.

**Objectives**

At the end of the course, participants should be able to:

- explain the concept of lesson study in mathematics education;
- develop lesson study process in mathematics education;
- implement and participate in lesson study activity in mathematics education.
