Research

Charles Hohensee working with students on math problems in the Summer of 2022 as part of his NSF CAREER Grant.

Rarely has research on teaching and research on student learning been conducted simultaneously within the same classrooms. My research contributes to the emerging work that integrates an examination of what teachers do in the classroom and the resulting understanding that students develop.

My research examines what happens when learners form beginning conceptions of complex concepts at the middle and high school levels. More specifically, I am interested in the phenomenon of backward transfer, which is how learning something new influences a learner’s prior knowledge. For example, I have conducted a study that investigated how middle school students’ prior knowledge of linear functions changed as a result of learning about quadratic functions.

In 2017, I received the following five year NSF CAREER grant to further my research on backward transfer:  Investigating Backward Transfer Effects in the Context of Instructional Activities About Linear and Quadratic Functions ($880,300.00). National Science Foundation CAREER program through Discovery Research K-12 (DRK-12), 2017-2023.

In 2021, Dr. Joanne Lobato and I published the edited book with Springer on progressive perspectives on the transfer of learning:
