Fair use provisions of US copyright law allow limited use of copyrighted works without permission for purposes such as teaching. For classroom use, teachers can display full video works and incorporate short excerpts into student multimedia projects under fair use. Specifically, teachers can show movies in the classroom if it fits their lesson, and students can use up to 10% or three minutes of copyrighted video, 10% of a song, and limited images in their projects. Educators should follow these fair use guidelines when using copyrighted material for educational purposes.
