Jugyoukenkuu (or ‘Lesson Study’ as it is more widely known) is the Japanese art of teacher professional development. It involves the identification of an area of teaching that needs to be developed, by a group of teachers.
The group then plans a lesson together (the research lesson) to address that area of need (with a particular focus on specific students to monitor their progress). One teacher then delivers the research lesson, whilst the other members of the group observe the lesson. They then interview the target students to gauge their progress and engagement during the lesson. The lesson is then reviewed by the group, with strengths and further areas for development identified. The process is then repeated (with somebody else teaching the research lesson) based on this review – with a view to refining the teaching strategy being looked at.
