Collaborative Lesson Research

Collaborative Lesson Research is a registered charity run by educators for educators. Its purpose is to support activity that by many might be called lesson study. Fundamentally it involves teachers and other educators working in collaborative participatory action research that seeks to improve practice leading to better student learning. Our overarching term for such activity is collaborative lesson research - a term first introduced by our friend and colleague, Dr Akihiko Takahashi.

Collaborative lesson research (CLR) is a powerful form of teacher professional development focused on the design of lessons for student learning. In CLR, a group of teachers research a topic and rigorously design a proposal for a lesson. Many educators are often invited to observe, and all join a post-lesson discussion immediately following the lesson.

Inspired in particular by the practice of mathematics teachers and educators in Japan, Collaborative Lesson Research is practised internationally, and is growing in the UK.
