“…Not only do students of color disproportionately attend inner-city schools plagued with a lack of resources (Kozol, 2005), but within diverse schools, students of color and students with low socioeconomic status are frequently assigned to Special Education classes, placed in low-track classes, or otherwise deemed incapable of performing highly (Lucas, 1999;McDermott, Goldman, & Varenne, 2006;Oakes, Joseph, & Muir, 2003). Teacher beliefs about their students play a prominent role in what they do in their classrooms (Rousseau & Tate, 2003), as do contextual factors such as time, curriculum available, and teacher professional development (Rousseau & Powell, 2005), and there is ample evidence that what teachers do matters quite a bit for student achievement, persistence, and processes of positioning and identification (Perry, 2003). In mathematics education, all of these aspects of schooling, and the relationships between them, need to be taken into account if we are to make real progress towards equity.…”
