This article examines the work of three urban youths as they designed and taught a social justice class at an urban continuation high school in California, USA. Drawing from a two-year ethnographic study of the project, it shows that youth participants constructed a set of imagined binaries to frame teachers, schoolwork and coercion "in opposition to" students, voice and liberation. The article examines how the youths distinguished ordinary "coercive" teaching from their own "liberatory" teaching, creating a coercive/liberatory binary that served as metaphor for a series of binaries shaping their approach to social justice education: teacher/student, adult/youth and schoolwork/voice. It concludes that although the social justice class accomplished many important aims, the reconstruction of and reliance on a coercive/liberatory binary within the project ultimately limited its effectiveness as a social justice education effort.
