Atkins, Brown & Hammond (2007) define Open Educational Resources (OER) this way: "OER are teaching, learning and research materials that reside in the public domain or have been released under an intellectual property license that permits their free use or re-purposing by others."

Intro to OER

This EdWeek video provides an introduction to OER, including a definition of OER and an introduction of some of OER's benefits and common concerns. 

The 5Rs

David Wiley (2014) laid a foundation for OER when he developed the 5Rs of openness:


  • Retain – the right to make, own, and control copies of the content

  • Reuse – the right to use the content in a wide range of ways (e.g., in a class, in a study group, on a website, in a video)

  • Revise – the right to adapt, adjust, modify, or alter the content itself (e.g., translate the content into another language)

  • Remix – the right to combine the original or revised content with other open content to create something new (e.g., incorporate the content into a mashup)

  • Redistribute – the right to share copies of the original content, your revisions, or your remixes with others (e.g., give a copy of the content to a friend)
