Open educational resources (OER)

Open educational resources (OER) are teaching, learning, and research resources in the public domain or released with an open license (e.g., Creative Commons license). Anyone can freely use, copy, adapt, and reshare OER. The University of Arizona is an active member of the Open Education Network, which advances open education and resources. states that true OER are free to access and follow the 5R's of open content:

  1. Retain: make, own, and control copies of the content
  2. Reuse: use the content in a wide range of ways
  3. Revise: adapt, adjust, modify, or alter the content itself
  4. Remix: combine original or revised content with other material to create something new
  5. Redistribute: share copies of the original content, revisions, or remixes with others

All kinds of materials can be released as OER. A few examples are:

  • Software, videos, and games

Why OER?
