Lesson play is a novel construct in research and teachers' professional
development in mathematics education. Lesson play refers to a lesson or
part of a lesson presented in dialogue form--inspired in part by
Lakatos's evocative Proofs and Refutations--featuring imagined
interactions between a teacher and her/his students. We have been using
and refining our use of this tool for a number of years and using it in
a variety of situations involving mathematics thinking and learning. The
goal of this proposed book is to offer a comprehensive survey of the
affordances of the tool, the results of our studies--particularly in the
area of pre-service teacher education, and the reasons that the tool
offers such productive possibilities for both researchers and teacher
educators.
