Rate My Professor Tad Watanabe

Tad Watanabe is Professor of Mathematics Education and Associate Chair of the Department of Mathematics in the College of Science and Mathematics at Kennesaw State University, where he has served since 2006, advancing to full professor in 2011. He earned a Ph.D. in Mathematics Education from Florida State University, an M.S. in Mathematics from Purdue University, and a B.A. in Mathematics from Taylor University. Prior to Kennesaw State, Watanabe held positions as Associate Professor of Mathematics Education at Pennsylvania State University from 2002 to 2006 and at Towson University from 1998 to 2002, where he also served as Vice Chair. Earlier roles include Assistant Professor at Towson University from 1991 to 1998, Mathematics Instructor at North Florida Junior College, and Graduate Instructor positions at Florida State and Purdue Universities. His career emphasizes teacher preparation and mathematics instruction for elementary and middle grades.

Watanabe's research focuses on mathematics teaching and learning, with special attention to Japanese lesson study approaches, proportional reasoning, fractions, ratios, rates, and visual tools such as tape diagrams and double number lines. He has authored or co-authored scholarly books including Navigating through problem solving and reasoning in Grades 6–8 (2009, National Council of Teachers of Mathematics), Navigating through measurement in grades 6–8 (2005), and Elementary school teaching guide for the Japanese Course of Study: Arithmetic (Grades 1–6) (2004). Notable refereed articles include "Learning from Japanese lesson study" (2002, Educational Leadership), cited over 300 times, and "A developing approach to studying students’ learning through their mathematical activity" (2010, Cognition and Instruction). He has edited volumes such as What matters? Research trends in international comparative studies in mathematics education (2017) and secured grants as principal investigator, including National Science Foundation awards totaling over $100,000 and sub-awards from school partnerships. Watanabe received the Japan Society for the Promotion of Science Postdoctoral Fellowship in 2000. His work influences teacher education through publications in NCTM journals and presentations at national conferences.
