Lesson Study: Improving Instruction One Lesson at a Time

Originally used by Japanese teachers, lesson study emphasizes working in small groups to plan, teach, observe, and critique a lesson. Lesson study involves groups of teachers in a collaborative process designed to systematically examine their practice with the goal of becoming more effective. Teachers College at Columbia University has many resources about the lesson study process (www.tc.columbia.edu/lessonstudy/lesson-study.html) and they've developed a lesson study protocol that describes how the process might work.

• Participants should be volunteers but the invitation to participate should be inclusive.
• While working on a study lesson, teachers work together to develop a detailed plan for the lesson.
• One member of the group teaches the lesson in a real classroom while other members of the group observe the lesson.
• The group comes together to discuss their observations about the lesson and student learning.
• The group works together to revise the lesson.
• Another teacher teaches the revised lesson while group members observe.
• The group reconvenes to discuss the observed lesson.
• The revision process may continue as long as the group believes it is necessary.
• Teachers talk about what the study lesson taught them and how they can apply the learning to their own classroom. They may prepare a report to be shared with others.

Lesson study is a valuable tool to engage teachers in examining their own work and developing plans for improvement. It is anchored in a collaborative culture where teachers are comfortable working together and talking about complex issues.

I'd enjoy hearing from you about your experience with lesson study or other professional development activities.
