%0 Journal Article %T Preparing future teachers to anticipate student difficulties in physics in a graduate-level course in physics, pedagogy, and education research %A John R. Thompson %A Warren M. Christensen %A Michael C. Wittmann %J Physical Review Special Topics. Physics Education Research %D 2011 %I %X We describe courses designed to help future teachers reflect on and discuss both physics content and student knowledge thereof. We use three kinds of activities: reading and discussing the literature, experiencing research-based curricular materials, and learning to use the basic research methods of physics education research. We present a general overview of the two courses we have designed as well as a framework for assessing student performance on physics content knowledge and one aspect of pedagogical content knowledge¡ªknowledge of student ideas¡ªabout one particular content area: electric circuits. We find that the quality of future teachers¡¯ responses, especially on questions dealing with knowledge of student ideas, can be successfully categorized and may be higher for those with a nonphysics background than those with a physics background. %U http://link.aps.org/doi/10.1103/PhysRevSTPER.7.010108
