Rooted in graffiti culture and its attitude toward the world, street art is regarded as a postgraffiti movement. Street art encompasses a wide array of media and techniques, such as traditional spray-painted tags, stickers, stencils, posters, photocopies, murals, paper cutouts, mosaics, street installations, performances, and video projections displayed in urban streets. It represents the desire of humans to leave traces of their existence in the public sphere. As a vernacular art form, street art, such as the work of British artist Banksy, deals with activism, reclamation, and subversion and allows artists a platform to reach a broader audience than traditional art forms. Street art can serve to engage students in critical dialogue about art and visual culture while they collectively explore the issues it raises. This Instructional Resource describes a learning unit for high school students where they can address social and political issues by studying street art, specifically the work of Banksy.
