"But then I read about jugyokenkyu in Elizabeth Owen’s recent book. She explained this Japanese practice to mean literally “lesson study.” She describes this as, “practices that Japanese teaches use to hone their craft, from observing each other at work to discussing the lesson afterward to studying curriculum materials with colleagues.”
Ms. Owen tells how one Japanese instructor taught another teacher, “not how to give a lesson, but how to study teaching, using the cycle of jugyokenkyu to put his work under a microscope and improve it.” Given the obvious benefits, and proven track record of jugyokenkyu around the world, one might ask why these practices have been recognized by so few educational colleges or practitioners. In part I believe it is because most teachers are not aware of this approach, and secondly, it has little to do with administrators, superintendents or policy makers."
