Akihiko Takahashi

DePaul University
Associate Professor of Mathematics Education
Akihiko Takahashi, PhD, is an associate professor at DePaul University, where he teaches mathematics and mathematics education. Before coming to the US from Japan, he was a schoolteacher and then an educator of mathematics teachers. He was nationally active in mathematics Lesson Study (LS) in Japan, teaching public research lessons and writing many articles. He received his doctorate from the University of Illinois at Urbana-Champaign.

He is one the few educators in the US with more than twenty years of first-hand experience with LS in mathematics education. As a result, he has been recognized as one of the world leaders of LS research and practice since the inception of the movement in North America. He had the privilege of working with most of the major LS projects in twelve US states and around the world, helping enthusiastic educators and researchers learn about LS and develop LS communities.

In Chicago, he has used LS to introduce mathematics teaching reform to prospective and practicing teachers. Immediately after he moved to Chicago in 2002, he started a LS project with three elementary school teachers. This project, which became known as the Chicago Lesson Study Group, has established a reputation among LS researchers and educators in North America as a model of cross-school LS in an urban setting. The group’s reputation has attracted many researchers and educators who are interested not only in LS but also in mathematics education, extending as far as Singapore and Thailand, where researchers and educators have become interested in employing LS to improve the teaching and learning of mathematics.

He has published over 80 journal articles and book chapters in English and Japanese and given over 50 presentations and keynote at conferences and workshops in 18 countries.
