A Singapore Case of Lesson Study

In this article, we present a case study of six Singaporean elementary school teachers working in a Lesson Study team that prepared them for problem solving instruction. The Lesson Study process included preparing, observing, and critiquing mathematics lessons in the context of solving fractions tasks. By conducting Lesson Study, we anticipated that these teachers would develop greater insight into students’ mathematics, which would influence their classroom practices. Through the process of planning, observing and critiquing and by purposefully listening to students’ explanations, the teachers began to better understand their students’ learning, which in turn could help them develop their students’ mathematical knowledge.
