Eric Brewe is a Physics Education Researcher (PER) whose research is centered on Modeling Instruction. Modeling Instruction is a curriculum and pedagogy founded on the idea that science learning involves creation, use, validation, and revision of conceptual models. These conceptual models are built of coordinated representations and form the basis for classroom interactions. These conceptual models are hypothesized to be appropriated into students’ own mental models. Research on Modeling Instruction has included investigations of the efficacy of Modeling in student understanding, attitudes, and as an inclusive pedagogy. Extending the research to include studies of student interactions both in and outside of the class has led to the novel use of Network Analysis in PER. Findings from network analyses have linked student engagement in the classroom and outside to positive outcomes. Ongoing projects include networked studies of persistence and retention, investigations of the process of appropriation of conceptual models into mental models, and extensions of the Modeling Instruction approach. Dr. Brewe also serves as co-editor for Effective Practices in Physics Teacher Preparation, and an upcoming special issue of Physical Review ST– Physics Education Research on Gender.
