How Should Research Contribute to Instructional Improvement? The Case of Lesson Study.
Lewis, Catherine C., Rebecca R. Perry, and Akihiko Murata. "How Should Research Contribute to Instructional Improvement? The Case of Lesson Study." Educational Researcher 35, no. 3 (2006): 3-14. https://doi.org/10.3102/0013189X035003003.
Why this matters here
Lewis, Perry, and Murata’s Educational Researcher article presents lesson study as instructional improvement through repeated small loops—plan, observe, reflect, revise—rather than only through large centralized reform. Coupling uses that education case beside other domains where pilot-and-adjust cycles keep redesign nearer to operational feedback. The source argues how research can contribute via lesson-study practice; the book asks when simplification protects learning loops and when it strips the structure that made learning possible.
