The objectives of this project funded by the National Science Foundation are:
1. To investigate the variation in teachers’ practice of lesson study
2. To identify effective and scalable design features of lesson study associated with student mathematics learning growth in Florida.
Florida is the first state to promote lesson study as a statewide professional development model for implementing the state standards aligned with the Common Core State Standards in Mathematics (CCSSM) and improving instruction and student achievement. However, the original lesson study model imported from Japan poses a challenge for implementation and scalability in the United States, and there is emerging evidence that modifications have been made to make it feasible within the constraints of teachers’ work schedules and school structures. This project investigates the variation in lesson study practice and how the design features of mathematics lesson study are associated with improvement of student mathematics achievement.
