What makes an educational resource open?

An open educational resource (OER) is free to access and use and is licensed so that it can be shared and modified. The 5 Rs describe rights that users of OER have: they may Retain, Reuse, Revise, Remix, and Redistribute these materials. 

  • Retain - make, own, and control a copy of the resource (e.g., download and keep your own copy)
  • Revise - edit, adapt, and modify your copy of the resource (e.g., translate into another language)
  • Remix - combine your original or revised copy of the resource with other existing material to create something new (e.g., make a mashup)
  • Reuse - use your original, revised, or remixed copy of the resource publicly (e.g., on a website, in a presentation, in a class)
  • Redistribute - share copies of your original, revised, or remixed copy of the resource with others (e.g., post a copy online or give one to a friend)

Why use OER?

There are many advantages to using OER. These include:

  • Immediate, no-cost access to learning materials. Students save money and can engage with coursework from day one through the end of the course and beyond.
  • Adaptability to fit course needs. Because instructors can revise and remix at will, they can ensure that their course materials cover the required topics in a way that is tailored for and representative of their students.
  • Accessibility to meet student learning accommodations. Because OER can be revised and remixed, there are no copyright-based restrictions on reformatting materials.
  • Independence from commercial publisher and distributor constraints. Instructors and students can avoid the promotion of unnecessary new editions of textbooks.
