Knowledge Assets to Support the Science Instruction of Elementary Teachers (ASSET) is exploring a method for generating collective pedagogical content knowledge (C-PCK). This method will be tested through the creation of a web-based repository for elementary grades science teachers in two content areas: (1) properties and structure of matter and (2) ecosystems. To begin, the two content areas will be unpacked into key ideas. Literature reviews and discussions with experts will help determine what is known in the field about teaching and learning of each of the key ideas, including common patterns of student thinking and successful instructional strategies. Once the repository is complete, local teachers will test its functionality and use its resources to plan for and teach lessons related to the two areas of content. Data collected about the teachers’ understanding and use of the repository will inform revisions to the C-PCK collection and synthesis method.
