His research into the teaching and learning of physics at the university level includes developing curriculum for the Modeling Instruction course, leading inquiries into the role of Modeling Instruction in promoting student learning, participation, retention & persistence, enhanced attitudes toward science and equity. This research has led to describing the role of participation in learning using primarily quantitative measures including the use of Network Analyses, and recently applications of machine learning and natural language processing. In addition to research on post secondary physics, Dr. Brewe has been involved in preparing future physics teachers through Modeling Workshops, and as co-editor of the PhysTEC sponsored book, Recruiting and Educating Future Physics Teachers: Case Studies and Effective Practices. Dr. Brewe helped to found the American Physical Society’s Topical Group on Physics Education Research (GPER) and served as the founding Chair of GPER.
