Open Educational Resources (OER)Open Educational Resources (OERs) are teaching and learning materials that you may freely use and reuse at no cost, and without needing to ask permission. OERs have been authored or created by an individual or organization using a Creative Commons license or other permission to let you know how the material may be used, reused, adapted and shared. OERs range from textbooks to curricula, syllabi, lecture notes, assignments, tests, projects, audio, video and animation. For students, OERs offer free access to some of the world’s best courses and educational content. They can also offer huge cost savings as alternatives to expensive textbooks.
