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.

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.
