ABSTRACT
Although the lower grade teachers completed work on their subtraction lesson on November 18, major lesson study work still lay ahead of them for the remainder of the 1993-1994 academic year. In particular, these teachers still had to help with a lesson study open house and they would also take part in a schoolwide end of year reflection about the konaikenshu work carried out at the school that year. In this chapter we first describe the planning and conduct of the open house in order to give the reader a better understanding of what this type of event entails and its function in the lesson study process. Next we provide an account of how the teachers went about reflecting on their work.
