"'Open Educational Resources' are high-quality teaching, learning, and research resources that reside in the public domain or have been released under an intellectual property license, such as a Creative Commons license, that permits their free use and repurposing by others, and may include other resources that are legally available and free of cost to students. 'Open educational resources' include, but are not limited to, full courses, course materials, modules, textbooks, faculty-created content, streaming videos, tests, software, and any other tools, materials, or techniques used to support access to knowledge."
This video is intended to serve as an introduction to OERs for college professors.
Beyond the obvious benefits that come from the cost savings to students, research has shown that OERs have a significant effect on student success. Students provided with free instructional materials at the beginning of a term have been shown to have much better success in their courses, as measured by a variety of metrics.
