Kyozaikenkyu: A Critical Step for Conducting Effective Lesson Study and Beyond
As lesson study becomes more widely practiced in the United States, it is important that lesson study practitioners shift their focus from simply practicing lesson study to practicing lesson study effectively and meaningfully. In this chapter, we describe an important process in lesson study called kyozaikenkyu. We argue that a deep and critical kyozaikenkyu is an essential component of successful lesson study. We also discuss some implications for mathematics teacher educators in their work with both preservice and inservice teachers.
