Theodore Chao is an esteemed assistant professor of Mathematics Education at The Ohio State University, whose research aims to advance critical pedagogy and equity through math. Dr. Chao's innovative work delves into the use of photographs and video to stimulate mathematical discussion and reflection while also exploring how math teachers can confront the intersection of their ethnic and professional identities. A former teacher at NYC Department of Education, Dr. Chao has developed mobile apps to help kids share and discuss their mathematical strategies with teachers and written equity briefs for numerous teacher organizations. Dr. Chao is currently co-PI on an IES-funded project S3: A Game-based 3rd-grade Math Curriculum, which focuses on using an online, game-based interface to initiate rich mathematical classroom discussions. His academic background includes a Doctorate in Mathematics Education from The University of Texas at Austin, an Education Masters from St. John's University, a Computer Science BS, and a Film and Media Studies BA from The Johns Hopkins University.
