The intersection of lesson study and design research: A 3-D visualization development project for the elementary mathematics curriculum

Abstract

This chapter describes how the research methods for developing a 3-D visualization program for elementary children closely resemble the principles of lesson study. While many lesson study experiences offer teachers opportunities for personal professional development to deepen their pedagogical content knowledge, this team's immediate focus is on students' mathematical understanding as they engage in research lesson activities that are the basis for development of new materials for the elementary mathematics classroom. © 2011 Springer Science+Business Media B.V.
