Welcome to TheodoreChao.com.

Theodore Chao is an assistant professor of Mathematics Education in the Department of Teaching and Learning at The Ohio State University. His research agenda involves empowering all students and teachers regardless of social identity (race, gender, socioeconomic status, etc.), to learn and teach mathematics, particularly through technology. He uses Photovoice interviews to explore how mathematics teacher of color connect their mathematics teacher identities with racialized social identities. He also builds mobile app technology to help children share mathematical strategies with each other, opening up windows for teachers to listen to their children’s mathematical thinking.


Dr. Chao has published in journals such as Investigations in Mathematics Learning, Contemporary Issues in Technology and Teacher Education, Mathematics Teacher Education and Development, Digital Experiences in Mathematics Education, and Education Sciences. Dr. Chao has been a Principal Investigator on two U.S. Department of Education funded projects exploring how online, game-based mathematics curriculum helps elementary teachers’ structure and orchestrate rich mathematical classroom discussions.


At The Ohio State University, Dr. Chao has taught EDUTL 5108 Elementary Teaching and Learning of Mathematics for Grades PreK-3, EDUTL 8741 A Critical History of STEM Curriculum, EDUTL 5005 Equity and Diversity in Education, EDUTL 7194 Mobile Learning Technology in STEM Education, and EDUTL 8711 Current Issues and Trends in STEM Education.


Dr. Chao is currently an editor for the Postscripts section of Teaching Children Mathematics (TCM), an editorial panel member of Mathematics Teacher Educator (MTE), a steering committee member of the North American Chapter of the International Group for the Psychology of Mathematics Education (PME-NA), and an organizer for the Free Minds, Free People (FMFP) conference. Dr. Chao also consults for Penguin Random House Books and provides teacher professional development for Columbus City Schools.
