Open Educational Resources (OER) are teaching and learning tools that are freely licensed for reuse and remixing. Educators are permitted and encouraged to modify and expand OER as they see fit, and republish their versions for further reuse and improvement. OER may include course modules, textbooks, podcasts, online courses, journals, etc.
Many web resources exist to promote the distribution and collaborative development of OER. Some examples: Connexions, WikiEducator, OpenCourseware.
When republishing OER, compatibility is often a concern: not all OER producers or communities use the same license.
