Lesson Study is a teaching improvement process that has origins in Japan where it is a widespread professional development practice. However, it is now practised internationally (e.g., US, China, Europe incl.Ireland) with student teachers and in schools/HEI’s. Working in a small groups, teachers/educators collaborate with one another, discuss learning goals, plan an actual classroom lesson (called a “research lesson”), observe how their ideas work in an actual lessons with students and then analyse the lesson from the perspective of students’ learning and development of thinking. Lesson Study has been used as a basis of research, and teaching and learning activities in SPD since 2006. It is currently being used to

1. develop preservice and qualified teachers’ mathematical knowledge for teaching,
2. research primary/post-primary transitions in mathematics and
3. facilitate school-based CPD.
