I think a course on 'copyright laws' should be required for each new instructor. I rarely hear coworkers discussing this issue and it's because there is so little understanding if it.
Copyright law period, utilizing articles more than once would require permission although the article is posted online.
I never realized the Fair Use Act, which I think many instructors rely upon to help them know what and how much information they can use from a source, doesn't apply at all to for profit institutions.
While the legal guidelines covering copyrights are slow to keep up with changes and technologies, instructors must be cognizant of the potential copyright violations when introducing materials in their classroom. There are many sources of information to help with this and that can support developing and updating an institution's copyright policies.
I see this being more of an issue now that we have Chat GPT and other AI avenues that students can use. I wonder how copyright fits into AI information.
There is a difference between non-profit and for-profit institutions in what the law allows.
