This essay explores the need to prepare educators to teach their students to think critically about the media and information they use and encounter daily so they can become empowered citizens with a sense of agency to use these tools to participate in shaping democracy. After reviewing the dearth of teacher training in media education, the author describes his experiences teaching a graduate-level course for preservice and working teachers in critical media literacy. This course is based on a theoretical framework from cultural studies and critical pedagogy that expands the notion of literacy to include multiple types of texts as well as deepens the critical analysis to question the connections between information and power.
