MEET THE TEAM

Dr. Theodore Chao

Dr. Theodore Chao is an Associate Professor of Mathematics Education at The Ohio State University in Columbus, Ohio.

Using video, photovoice, and narrative, his work focuses on mathematics education, storytelling, and organizing with children, teachers, and community to decolonize our educational system.

He has published in journals such as Mathematics Teacher Educator, Race, Ethnicity, and Education, and Investigations into Mathematics Learning, presented at conferences such as the American Educational Research Association, the Association of Mathematics Teacher Educators, and the European Association for Research in Learning and Instruction.

Currently, he is a Fulbright Scholar, exploring the use of digital storytelling to unpack community mathematics stories in Vietnam and Indonesia. He is also a Principal Investigator on a National Science Foundation-funded CAREER research grant, Digital Mathematics Storytelling.

For the 2022-23 academic year, Dr. Chao will be joining University of California, Los Angeles Mathematics Project at Center X as a visiting researcher.


Ho-Chieh Lin

Ho-Chieh Lin, a Fulbright scholar from Taiwan, is currently a Ph.D. candidate in the Department of Teaching and Learning at The Ohio State University. Lin’s research addresses topics in Mathematics/STEM education, including technology integration, equity issues, and fractions cognition. His current research project investigates how children communicate their thinking around mathematical videos. He also designs a video-based online environment for promoting mathematical justification. The preliminary findings show that this environment creates opportunities for children to express their authentic ideas and engage in mathematical discussions with their peers.

Prior to his studies at OSU, Lin had taught elementary schools in Taiwan and the United States for several years. Particularly, he loves teaching mathematics, science, and language arts.

Angga Hidayat

Angga is a Fulbright scholarship grantee from Indonesia. Currently, Angga is pursuing a doctoral degree at Ohio State University with a research concentration on mobile learning in mathematics classrooms. His future goal is to be a specialist in mathematics education then develop a mobile app so that students in urban and rural areas have the same learning quality. Angga has published some articles related to e-learning, augmented reality, math anxiety, and self-concept. Angga also has experience as an editor-in-chief of scientific journals for four years.

Before continuing his Ph.D. at Ohio State University, Angga taught at Universitas Pamulang, Indonesia. In addition, Angga has routinely been a volunteer teacher at rural schools, such as Bani Fadil Vocational School in Indonesia, since 2017. Angga also manage a volunteer team to teach at orphanage, to be exact, at Al-Kamilah Foundation. Angga believes that every student deserves the best education for a better future.

Ruth Oliwe

Ruth Nneoma Oliwe is a PhD student in Science, Technology, Engineering, and Mathematics Education at The Ohio State University. She has a B.Sc. in Mathematics from Michael Okpara University of Agriculture, Umudike, Abia State, Nigeria. She is a Graduate Research Associate on the Digital Mathematics Storytelling project .

Her research interests encompass using comics storytelling to explore and understand the intersections of Black girls’ narratives, the development of their mathematics identities, and how these narratives challenge Eurocentric framings of global mathematics knowledge, especially within Algebra and Black communities.

Ruth writes and creates comics as resources to showcase and teach relevant life skills, the beauty of family and community, and ways in which mathematics plays out in students’ immediate environments.
