Open Educational Resources (OER)

Lyryx is strengthening OER by developing a sustainable financial model for the continuous improvement of quality open materials. We work with educators, subject matter experts, and students to create and edit OER which are freely available to all. To support this mission, we develop and provide value-added services for affordable fees; high-quality online assessment, instructor and student support, technical support, and editorial services. This page is devoted to exploring the movement that is OER.

Open Educational Resources (OER) are defined by the Hewlett Foundation as “teaching, learning, and research resources that reside in the public domain or have been released under an intellectual property license that permits their free use and repurposing by others” (

The permissions inherent to OER can be summarized by the 5Rs as defined by David Wiley:

  1. Retain – the right to make, own, and control copies of the content (e.g., download, duplicate, store, and manage)
  2. 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)
  3. Revise – the right to adapt, adjust, modify, or alter the content itself (e.g., translate the content into another language)
  4. Remix – the right to combine the original or revised content with other material to create something new (e.g., incorporate the content into a mashup)
  5. 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)
