Open Education Resources (OER) are teaching, learning, and research materials that can be shared, used, and adapted without cost. This is made possible by an open license copyright, usually from Creative Commons, which gives users these permissions which are not normally granted under standard copyright law. You can learn more about open licenses by navigating to the Open Licenses and Copyright tab on this guide.
OER are not just textbooks, but can encompass most types of resources used in coursework including: Lab Manuals, Workbooks, Tutorials, Course Shells/Modules, Lecture Notes or Slides, Quizzes, Tests, Study Guides, Videos, Software, Syllabi, and more that are shared with Open Licensing.
Open Licensing gives users the ability to revise, remix, reuse, retain, and redistribute materials - this is known as the the 5Rs, a framework first developed by David Wiley.
