Teachers' views and expectations of students directly impact student learning, and unless they are challenged during the preparation period, these views are unlikely to change. This study investigated how a group of prospective teachers explained the shift in their perspectives of low-income, urban youth as a result of participating in a service-learning project that explicitly attended to issues of status and processes of unlearning. The findings indicate that when fused with student voice work, service learning can help prospective teachers to uncover, examine, and revise their assumptions about students, particularly those whose backgrounds differ from their own.
