Open Educational Resources (OER) are teaching, learning, and research materials that reside in the public domain or have been released under a Creative Commons license. OERs are free, so their use in the classroom can significantly reduce textbook costs for students. Under some licenses, users have permission to remix, revise, and redistribute the content of open materials.
