Open Resources

This guide provides you information on finding, creating, and sharing open resources.

What are Open Education Resource Repositories (OERR)?

An online storage system that allows educators to share, manage and use education resources. The repository contains a collection of learning items that support instruction. These items include:

  • open textbooks
  • lesson plans
  • quizzes (e.g. iclickers, etc.)
  • videos, animations, handouts
  • interactive activities and tools (e.g. apps)
  • powerpoint presentations

Open Education Repository Evaluation

All of the repositories on this page have been assessed with a top score using the Open Education Resource Repositories (OERR) Rubric. The assessment process is ongoing and this page will be updated as new OERR's are added. Click here to see the full list of assessed OERRs.

Note:  check the licenses of any OER materials before using — every effort has been made to identify repositories that prioritize open and reusable content, but licenses may vary.

Assessing Open Education Resources

Unlike libraries, where content is evaluated and curated from a set of items identified through publishers, open education resources can be found everywhere and anywhere and have no set form of evaluation before they are made available to the public. The following guide provides you with processes and tools for developing a open education resource research plan and evaluation considerations for resources:
