Beliefs about teaching mathematics and urban students' ability to learn mathematics are often overlooked in the discourse on highly qualified teachers. Altering teacher experiences has the potential to change their beliefs. It was found in this qualitative case study that preservice teachers' beliefs about teaching mathematics to urban students were changed after teachers taught brief sample lessons to their peers and watched video episodes of quality teaching. These findings suggest preservice teacher beliefs can be positively changed after taking reform-based mathematics methods courses. Additional studies are needed to determine if these changes can be sustained during teacher induction.
