Copyright in education seems obvious but there are so many issues that cloud what is legal and ethical. Teachers need to consider four issues when determining if a work is allowed under the principles of fair use:
the purpose and character of the use,
the nature of the copyrighted work,
the amount and substantiality of the portion to be used, and
the effect of the use upon the potential market.
Title 17, Chapter 1, Section 110 (2) of the Copyright Act (2002) referred to as the Technology, Education, and Copyright Harmonization (TEACH) Act, provides guidance for educators.
