The Learner-Centered Mathematics Education for Pre-Service Teachers (LCE-PST) grant was funded by the Arizona Board of Regents. The goals of the project were to (1) develop learner-centered mathematics curriculum materials for use with elementary education majors (pre-service teachers), (2) provide professional development for instructors who implement the curriculum materials, and (3) study how instructors use the materials in their courses and how students interact with the materials.
