Principles to Actions discusses lesson study as an exemplar professional development context in which teachers collaboratively research and reflect on their lessons, classroom practices, and student learning, and hold themselves and colleagues accountable for the success of all students. Florida is the first state to promote lesson study statewide in the United States. In this symposium, we will present five studies that investigated different aspects of this state-wide implementation of lesson study in Florida and its influences on schools, both quantitatively and qualitatively. Each paper frames the situation with different research questions, and after short presentations of each papers, we will invite audience to together discuss about development of professionalism of mathematics teachers.
