Educational fair use allows educators to use copyrighted material without permission for educational purposes. It considers whether the social or cultural benefits of the use outweigh the costs to the copyright owner. Educators can use excerpts from media like news, ads, movies and websites to teach critical thinking and communication skills as part of media literacy education. They should only use material pertinent to their educational goals and ensure it meets standards for curriculum development. Media literacy teaches that media messages are constructed, have embedded values and viewpoints, and people derive their own meanings from media. It strengthens skills when students analyze, deconstruct and recreate media messages.
