About Lesson Study

Lesson Study is a structured process for teachers to work together to discover solutions to common teaching-learning challenges. The members of Lesson Study Alliance help teachers and schools implement an especially powerful form of Lesson Study called Collaborative Lesson Research, or CLR.

Our activities include:

  • hosting the international Chicago Lesson Study Conference
  • hosting smaller conferences and training sessions for teams of teachers;
  • facilitating and giving final comments for research lessons;
  • providing site-based professional development, including knowledgeable other services; and
  • supporting and distributing LessonNote, a free iPad application used in classroom observation and discussion.
