Teachers’ Mathematical Knowledge: Its Development and Use in Teaching

Our proposed research agenda centers on building the resources needed for high-quality mathematics instruction. Given that the quality of instruction depends fundamentally on what teachers do with students to develop their mathematical proficiency, and given that what teachers can do depends fundamentally on their knowledge of mathematics, we recommend that the first of the three strands of research in the proposed program focus on the mathematical knowledge required for teaching mathematics and on the key resources needed to use that knowledge in teaching. In particular, this strand of research would focus on the materials and institutional contexts that support the deployment of mathematical knowledge in teaching.
