Open Educational Resources (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 repurposing by others."* This means, OER are free of most copyright restrictions, and as such are ideal for use in online teaching. OER May include full textbooks, or other tools such as streaming media, images, open access publications, and more.
