Supporting the development of curricular knowledge among novice physics instructors

In this paper, my aim is to problematize the invisibility (to instructors) of the purposes of particular exercises within research-based instructional materials (RBIMs) and to provide one possible solution to this problem that other teacher educators may adapt for their institutional contexts. In particular, I show that many RBIMs anticipate and respond to particular (often incorrect) learner ideas, that teachers often do not recognize this, and that not recognizing this can cause teachers to miss opportunities to build on learner ideas and/or engage students in scientific practices. I share an instructional activity I designed that is meant to support teachers-including university physics Learning Assistants-in recognizing the purposes of particular questions or sequences of questions within RBIMs, and I illustrate that this activity can be a productive starting place for conversation about RBIMs. (C) 2018 American Association of Physics Teachers.
