Introduction

What are Open Educational Resources (OER)?

UNESCO defines Open Educational Resources (OER) as, “teaching, learning and research materials in any medium – digital or otherwise – that reside in the public domain or have been released under an open license that permits no-cost access, use, adaptation and redistribution by others with no or limited restrictions.” The term “open” in OER generally refers to resources with free permission to engage in the 5R activities: retain, reuse, revise, remix, and redistribute.

This guide is indexed by discipline and links to open resources (Creative Commons, Open Access (OA), governmental, open source, linking allowances within the Terms of Use (TOU), etc.). Most resources will have the license indicated at the end of the resource description.


The 5 Rs: Retain, Reuse, Revise, Remix, Redistribute

The 5 Rs of Open

  • Retain: make, own, and control a copy of the resource (e.g., download and keep your own copy)
  • Reuse: use your original, revised, or remixed copy of the resource publicly (e.g., on a website, in a presentation, in a class)
  • 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)
  • 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).
