Bansho as part of lesson and lesson study: from the origins to the present

Abstract

PurposeThis paper aims to provide an overview of the origins of bansho, how it has developed to be an indispensable practice in Japan and its influence on countries outside Japan. The integration of bansho into lesson study (LS) will also be presented.Design/methodology/approachThis paper draws on the vast literature on bansho from both in and outside Japan to illustrate the points mentioned above.FindingsRecapitulation on the history of chalkboard and bansho in different eras in Japan illustrated its endurance towards the test of time, geographical space and functions. While bansho remains a constant presence in LS research, there has not been any work that outlines how bansho is integrated into the LS cycle. Thus, a guideline on how bansho can be incorporated in the LS cycle is provided.Originality/valueA comprehensive overview of bansho allows educators and researchers outside Japan to move beyond the know-how and know-what of bansho; it would serve as an invaluable source to understand the core concepts underlying this classroom practice, thus avoiding the mere adaptation of bansho superficial aspects. This study also provides precise instruction on how bansho can be integrated into each step of the LS cycle, which will guide teachers and researchers in the future implementation of LS.
