Open Educational Resources (OER) are educational materials that are licensed in ways that allow us to legally and freely copy, use, adapt and re-share them.
OERs include courses, textbooks, assignments, tests, projects, software, audio, video and animation.
OERs provide access to all kinds of resources for the educational benefit of people from all backgrounds in our global community.
If you create an OER, you can retain ownership of your work but still allow others to use, share, and remix it. You can assign a Creative Commons (CC) licence so that users must attribute you for your work.
The terms "open content" and "open educational resources" describe any copyrightable work that is either in the public domain or licensed in a manner that provides everyone with free and perpetual permission to engage in the 5R activities:
