Evaluate OER

Evaluation Process

Here are a few steps you might take in the evaluation process. If this process seems lengthy, think about the process you follow to review textbooks and other materials for your course. You can use a similar or modified evaluation process.

  1. Does this OER cover the content you’d like your students to learn in this course or module?
  2. How accessible is this content? Will it be accessible for your students, or is it too technical? Is it robust and challenging enough for your students?
  3. How can you use the content? Verify the license that the resource is under. Can you remix or revise the OER as long as it isn’t for commercial purposes? Who do you have to acknowledge or credit if you use it? Will you be able to do so? For more help with this, please contact the library.
  4. Once you determine how you can use the OER, what would you like to do with it? Does only a portion of it apply to your class? Would you possibly want to combine this OER with another OER or resource? Does the library have access to articles that could act as supplemental readings? We’ll be happy to help you find sources that are licensed under our campus subscriptions!
  5. As you collect more OER and other resources, you may want to save them in a central location. Take note of how you envision using them. Align these resources with the learning objectives and weekly lessons on your syllabus in order to identify gaps. For more help with this, please contact the Center for Academic Innovation.
