"Open Educational Resources are teaching, learning, and research materials in any medium - digital or otherwise - that reside in the public domain or have been released under an open license that permits no-cost access, use, adaptation and redistribution by others with no or limited restrictions" - UNESCO
Adopting OER in your course can provide several benefits, including:
OER allows us to (creatively) rethink the materials that we use for our course rather than rethinking our course around available textbooks.
Reuse: Use the resource in a variety of ways, as it currently exists.
Remix: Combine two or more OERs to create a content mashup.
Redistribute: Share the original, revised, or remixed OERs.
Revise: Adapt, modify, and improve the resources to fit your needs.
Retain: Make, own, and control your copies of the content.
