This article interrogates how hiphop composition pedagogies can interrupt what the author terms the "hiphop illiteracies" that circulate in predominantly white institutions (PWIs). An analysis of four college writing classrooms that integrate hiphop texts at one PWI reveals pervasive anti-Blackness in student attitudes, but also in the research and course design as well as in department-mandated course texts. The analysis demonstrates the need for writing pedagogies that name and teach Black language, writing, and meaning-making practices while also asking students, teachers, and administrators to reflexively examine their own identities' locations vis-a-vis those practices. The author advocates a reflexive pedagogy that asks students to locate themselves vis-a-vis power as a starting point for investigations of language and culture. The author concludes that hiphop pedagogies have significant critical social justice possibilities in institutionally white educational contexts, but these benefits are not automatic and demand pedagogies of reflexivity, sociolinguistics, and intersectional feminism.
