Building on the work of Ball and Cohen and that of Davis and Krajcik, as well as more recent research related to K12 teacher learning from and about curriculum materials, we seek to answer the question, How can educative curriculum materials be developed to support teacher educators in acquiring the knowledge needed for teaching science teachers? We present a set of theoretically and empirically based design principles and conceptual examples of ways in which educative curriculum materials might be used to support teacher educators in developing the knowledge needed for teaching elementary pre-service teachers. Specifically, we focus on helping teacher educators develop prospective teachers’ content knowledge for teaching about the structure and properties of matter.We follow these examples with consideration of unanswered questions related to the use of educative curriculum materials by teacher educators. This poster was prepared for the 2020 Annual International NARST Conference.

This study explores how teachers across the United States answer and reason on “teacher assessment tasks” designed to elicit content knowledge for teaching (CKT) about matter and its interactions. It leverages a think aloud approach, where participants were asked to reason about different assessment items that described teaching scenarios related to elementary science instruction about topics such as properties of matter, changes in matter, the particulate model of matter, and conservation of matter. Specifically, this study investigates: (1) To what extent do the participants use the intended knowledge and reasoning when responding to items designed to assess their CKT about matter and its interactions? and (2) When participants struggle to respond accurately to these items, what were their reasons for doing so? In particular, we were interested in examining the patterns in the nature of the knowledge they fail to leverage when responding to these CKT matter items.
