About Open Educational Resources
Open Educational Resources (OER) are teaching and learning resources that are free of cost and access barriers, and which also carry legal permission for open use. Generally, this permission is granted by use of an open license (for example, Creative Commons licenses) which allows anyone to freely use, adapt and share the resource—anytime, anywhere. Read more about OER at SPARC (the Scholarly Publishing and Academic Resources Coalition).
Required materials, like textbooks, can represent a significant cost to students. A recent U.S. PIRG study found that the cost of textbooks has risen over four times the rate of inflation. Instructors can directly influence the cost of education for their students by adopting low- or no-cost course materials. The boxes below provide some starting points for discovering OER for your course. For further help, please contact your library liaison or instructional technologist.
Please read more here about an opportunity for a stipend of up to $1,500 to incorporate OER materials into a Trinity course.
