OER & Affordable Learning Materials (ALM)

Consider ALL 5 R's when Creating OERs

The 5 Rs of OER Revisited: Retain, Reuse, Revise, Remix, & Redistribute

  • True OER is more than just free content to use in courses
  • Revising and remixing of content are what allow for innovation, customization, and open pedagogy 
  • Materials are most easily revised and remixed when they are not tied to a specific software program or proprietary platform
  • This means in order to allow for the greatest amount of reuse, revision, and remixing, OER creators need to consider the tools they are using to make the resources.
