Promoting Instructional Change via Co-Teaching

Abstract

Physics Education Research (PER) has made significant progress in developing knowledge about teaching and learning as well as effective instructional strategies based on this knowledge. Disseminating knowledge and strategies to other faculty, however, has proven difficult. Coteaching is a promising and cost-effective alternative to traditional professional development that may be applicable in many situations. In this article, we discuss the theoretical background of co-teaching and describe our initial experience with co-teaching. A new instructor (MF) cotaught with an instructor experienced in PER-based reforms (CH). The pair worked within the scaffolding of the course structure typically used by the experienced instructor and met regularly to discuss instructional decisions. An outsider (AB) conducted separate interviews with each instructor at the beginning, middle, and end of the semester and observed several class sessions. Classroom observations show an immediate use of PER-based instructional practices by the new instructor. Interviews show a significant shift in the new instructor's beliefs about teaching and intentions towards future use of the PER-based instructional approaches.
