OER: Open Educational Resources

OER are any type of educational material that are freely available for teachers and students to use, adapt, share, and reuse.


Are you considering incorporating open resources into your course to save students money and improve teaching and learning? 

Once you've found the right resource, you may want to make modifications to suit your particular class! Look below for a helpful guide for modifying Open Textbooks and OER, including examples from several common formats. 

Adoption Steps

  • Set aside time
    • Searching for these materials takes time and persistence, just like research!
  • Take a look to see if someone else has created a similar, complete OER course or textbook.
    • See the "Complete Courses" and "Complete Textbooks" sections of the "Finding OER" page.
  • Get cozy with your learning objectives.
    • Instead of focusing on the textbook that you would like to replace, focus on what you would like students to know or be able to do. You will likely need to search for several materials to address different topics or components of your complete class.
    • Example: instead of searching for “biology” materials, search for “cell structure” or “DNA” or “evolution” materials.
  • Use Google “Advanced Search” to search for open resources.
  • Search within some of the specific OER repositories/OER search engines
    • See the "Find ind OER" page for a list.
    • *OER Pro Tip* Use the browsing tools that the repository or search engine presents to you! Don’t rely solely on keyword searching.
  • Look for library materials like eBooks, articles and streaming videos to fill in gaps.
  • Not finding what you’re looking for? Ask your librarian.
    • We are happy to help or refer you! Send an e-mail to our OER team.
