Virtually any materials pertinent to the course of study may be shown to enrolled students in the face-to-face classroom.
The TEACH Act (Technology, Education, and Copyright Harmonization Act of 2002) allows access to works via the Internet or other distance education media similar to that provided for the classroom under the Teaching Exemption (exception: only portions of dramatic works and audiovisuals may be provided to distant students). You must restrict use to enrolled students, only make the material available for viewing during the relevant portion of the course, and limit downloading of materials in the same way distribution is restricted by Fair Use (for one semester for each course). TEACH Act applies only to government and accredited non-profit educational institutions.
Fair Use of a copyrighted work for purposes such as teaching, scholarship or research, criticism, comment, and news reporting is NOT an infringement of copyright. Fair Use covers copying and distribution of copyrighted works to students and is subject to conditions set out below. In determining whether your use is covered by Fair Use, four factors, described below, are considered. After you decide that Fair Use covers the materials that you are interested in sharing with students, you have restrictions on how the materials may be used.
