What can online lesson study offer?: Findings from an Australian-Japanese collaboration

This chapter aims to show the potential of international online lesson study to deconstruct both mathematics classroom practice and the process of lesson study itself, thus deepening our knowledge of both our own and the ‘other’s’ practices. The chapter is based on an analysis of the second of two online, interactive, lesson studies conducted as Zoom webinars as part of an Australian-Japanese collaboration. The webinars were based on archival video from a Japanese and an Australian research lesson, with participants expected to engage with rich resources in advance. Evidence shows that having time to repeatedly access the video and other materials enabled the participants to analyse the children’s work and the classroom discourse more deeply than is usually possible, provoking questions about the curriculum, the tasks we use, and what we believe to be good lessons and why.
