Lesson Study and Teaching Mathematics Through Problem Solving: The Two Wheels of a Cart
The international education community has taken an interest in lesson study, the Japanese approach to school education. Lesson study first came to the attention of educators outside of Japan primarily through the publication of The Teaching Gap (Stigler and Hiebert in The teaching gap: Best ideas from the world’s teachers for improving education in the classroom. The Free Press, New York, 1999) and the TIMSS video study, which showed the typical structure of Japanese mathematics instruction in the classroom. However, while there has been tremendous international interest in using lesson study as a model for professional development, there has been less of a focus on applying the method of Japanese mathematics instruction, which is teaching mathematics through problem solving. This paper discusses the interplay between lesson study and teaching mathematics through problem solving and outlines suggestions for educators seeking to improve both teaching and lesson study outside Japan.
