About Lesson Study 

Lesson Study is a structured process for teachers to work together to discover solutions to common teaching-learning challenges. Read “What is Lesson Study? A Primer”.

The members of Lesson Study Alliance help teachers and schools implement an especially powerful form of Lesson Study called Collaborative Lesson Research, or CLR.

About Us

We are a coalition of educators dedicated to helping each other and others learn about lesson study and use the process to improve teaching and learning. The most important work is done by the hard-working teachers who design and teach public research lessons, assist with the annual conference or summer workshops, and more. Backing them up are Tom McDougal, who handles the day-to-day business of Lesson Study Alliance and supports teachers through the lesson study process, and Dr. Akihiko Takahashi of DePaul, who contributes his expertise by giving talks and serving as a knowledgeable other.

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.
