Abstract
Lesson Study (LS) is considered a powerful tool for effecting teacher growth through
understanding student thinking and has spread to many countries over the past decade.
However, these LS implementations seem to have varied results. Some efforts have been
successful and still on-going, while others were somewhat successful but was not
sustained, ending up as wasted efforts. The success of introducing an innovation is
dependent on the extent the stakeholders are convinced by the innovation. However,
getting people to favour change is largely influenced by the extent to which the innovation
is aligned with what they value in their practice. This study aims to find out what values
are embedded within the construct of Lesson Study and to what extent Japanese
mathematics teachers endorse these values. It is also hoped that this study of Japanese
mathematics teachers can alert us to potential areas of tension that may arise when LS is
implemented in a different national context.
