A Deeper Look at Lesson Study

From Educational Leadership, February 2004.


Will lesson study become an important tool for instructional improvement, or is it a short-lived fad? Many promising innovations die because their visible features are implemented ritualistically, without a clear grasp of how they relate to instructional improvement. This points to the importance of understanding not just an innovation’s visible features–such as planning, observing, and rethinking a lesson, in the case of lesson study–but also the underlying pathways that link the innovation to instructional improvement.
