“OER are teaching, learning, and research resources that reside in the public domain or have been released under an intellectual property license that permits their free use and re-purposing by others. Open educational resources include full courses, course materials, modules, textbooks, streaming videos, tests, software, and any other tools, materials, or techniques used to support access to knowledge.”
The key distinguishing factor is the copyright status of the material. If course content is copyrighted under traditional, all-rights-reserved copyright, then it’s not OER. If it resides in the public domain, or carries Creative Commons or similar open copyright status, then it is OER.
