M13 Lesson Study on Bar Model
The document discusses a lesson study conducted at Pathlight School in Singapore focused on primary five mathematics, specifically using bar models to engage students in learning. It outlines the professional learning goals of the educators involved, their planning process, and the observations made during the lesson regarding student engagement types. The use of colored paper strips was evaluated for its effectiveness in helping students relate diagrams to problem situations, while calculations were primarily done independently by students.

The purpose of Photo: Pathlight School the research lesson is for teachers to observe students to answer questions such as this one. The lesson planning meetings raised such questions. The research lesson provides a platform to ‘see’ the answers to such questions. The post-lesson discussion is a platform to discuss these answers.
