James Tarr is a Professor of Mathematics Education and Chair of the Department of Learning, Teaching, and Curriculum at the University of Missouri. He has participated in leadership roles on seven federal grants, including as co-PI on the COSMIC project that examined complex relationships between mathematics content organization, curriculum implementation, the classroom learning environment, and students’ mathematics learning. Project research has garnered national media attention, was featured on the National Science Foundation homepage, and Tarr presented findings in Taiwan upon an invitation from their government.

Tarr currently serves as co-PI on the STEAM project that investigates the impact of student mathematics learning outcomes of Elementary Mathematics Specialists in self-contained or departmentalized teaching assignments. He is also PI on a Noyce project that is increasing the number of mathematics teachers through the recruitment of mathematics majors into teaching careers, preparation to teach mathematics aligned with national standards, and support of mathematics teachers in their induction years as they serve in high-needs school districts. He is co-author of a chapter on curriculum research in the forthcoming Compendium for Research in Mathematics Education and teaches methods courses for preservice mathematics teachers as well as seminars in the mathematics education Ph.D. program.
