A Teacher-led Case Study of Lesson Study in Action

This paper describes a team of mathematics teachers involved in lesson study initiatives carried out by the school. Following the lesson study model provided by the Japanese, a team of mathematics teachers embark on this project. They planned a unit on teaching ‘box and whisker diagram ’ to a group of Secondary Three Female students. The team met with several challenges while carrying out the lesson study including time, identification of broad goals for the unit, alignment of lesson goals with school goals and missions, researching for materials, etc. Nevertheless, the teachers feel that it is a worthwhile experience because it builds collegiality among the teachers in the team. They benefited in terms of gain in content knowledge and pedagogical knowledge, in particular focusing on the pupils ’ learning through observations. This paper hopes to provide mathematic teachers and educators with insights into implementing lesson study in the local context
