In this paper, we deploy M.M. Bakhtin's notions about how language works to understand aspiring teachers' struggles about the intersecting roles race, class, gender, language background, and sexual orientation play in students' school lives and learning. Through life-history interviews and document analysis, we investigated the authoritative and internally persuasive discourses one aspiring teacher brought with her and took from a 15-week long course on a predominantly White Midwestern public university campus. Ideas she encountered in the course and its required tutoring component challenged her thinking about how various facets of people's lives (such as those we list above) and the contexts in which they live, work and are schooled, affect how they are perceived, what they know, and can do.
