This document summarizes a study that assessed how two teacher training programs addressed cultural diversity in mathematics instruction. Classroom observations found one class had little student interaction and was teacher-centered, while the other encouraged high student participation. Both programs' curricula embraced diversity but did not sufficiently address dismantling dominant cultural practices or empowering minority students. The study indicates teacher educators' theoretical framework on multiculturalism determines the nature of exposure pre-service teachers receive regarding culturally affirming mathematics instruction.
