Critical media literacy art education teaches students to: (1) appreciate the aesthetic qualities of media; (2) critically negotiate meanings and analyze media culture as products of social struggle; and (3) use media technologies as instruments of creative expression and social activism. In concert with art education practices oriented toward critical media literacy, this article explores the power of logos in visual/media communication and the concepts of "subvertising," "culture jamming," and "media activism." It also describes a media literacy art project developed and implemented in a middle school art classroom. This project allowed public school youngsters to question the domination of corporate America over media advertising and programming and how it plays a central role in influencing what people consume, experience, and believe in their everyday lives. The project further involved them in deconstructing media constructs through logo design, subvertising, and culture jamming. The students applied what they learned to create subvertisements that raise public awareness of important social issues ranging from global warming to cyber safety, consumption and obesity, to child abuse and homelessness.
