The Technology, Education, and Copyright Harmonization (TEACH) Act of 2002 deals primarily with the use of copyrighted materials in distance education or distance learning. It amended Chapter 1 of Title 17 US Code (Copyright Law) and grants exemption for the use of copyrighted materials in specific classroom settings under certain circumstances.
While not as flexible as fair use in general or exemptions for face-to-face classroom settings, it does support educators by allowing transmission of dramatic and audiovisual works as long as they are of "reasonable and limited portions." You may find that, in "many cases, you will need to rely on both exceptions [Fair Use and TEACH Act]--or even entirely on fair use--to meet your educational goals" (via Ball State University).
