Blending music, science fiction and film, this is a study of why and how popular culture is taught in American classrooms. The author sets out to show that an informed awareness of politics, race and sexuality is essential to any understanding of the subject. He places rap music, the "Alien" trilogy and Sandra Cisneros in the context of postcolonialism, identity politics and technoculture, in an attempt to show students how they can draw on their existing literacies and on the cultures they know, in order to think critically.
