Japanese Lesson Study



Japanese Lesson Study


A group of teachers get together to research a specific topic, co-plan a lesson, and then one of them teaches the lesson while the others observe.  Teachers get together again to deconstruct and revise the lesson before the others deliver it, and the cycle continues.


  • Illustrates the complexity of teaching a single lesson, and thus reveals to teachers the importance of planning lessons
  • Shares responsibility for the lesson, so the focus is on improving teaching (not improving the “teacher”)
  • Allows for great input in the researching and planning stages.
  • Allows teachers to focus on the relationship between instructional decisions and student learning
  • Promotes agency as the teachers determine the needs, the method, and the results
  • Provides the opportunity for application of reflection and revision of work
  • Is ongoing
  • Develops community
  • Deprivatizes practice


  • Easiest to organize if all teachers work in the same school and teach the same grade
  • Time intensive and costly as it requires teachers to work together
  • Requires risk-taking and a degree of personal commitment
