Just like with traditional educational materials, OER are not all of uniform quality, so it is valid to question how to evaluate, or trust others' evaluations, of OER. Similar to traditional educational materials, there are formal and informal methods of review OER are exposed to throughout their lifecycle.
Acknowledge concerns: The instructor's concerns about quality are valid, and just like commercial textbooks, OER can vary in quality. Many OER undergo similar or even more transparent review processes than commercial textbooks.
Introduce peer-reviewed OER repositories: Many OER repositories feature peer-reviewed materials, similar to traditional academic publishing, and some, like Open Textbook Library, MERLOT, and OER Commons allow faculty and subject matter experts to review and rate resources for accuracy, relevance, and quality. Examples:
Some OER projects invite third-party experts to evaluate materials, adding credibility to the review process. OpenStax, for example, uses subject-matter experts to review textbooks before publication.
Explain the OER quality control frameworks: Established, standardized rubrics and frameworks are frequently used to evaluate the quality of OER materials. In addition to content quality, many OER are reviewed for accessibility, ensuring that they meet universal design principles and are available to all learners, including those with disabilities.
Support structures for OER review: Explain that the institution’s academic support staff (including librarians, instructional designers, and OER specialists) are available to assist with evaluating the quality of OER. Support staff can help with:
Participate in OER communities: Connect the instructor with OER communities of practice or listservs where educators share resources, best practices, and feedback on the quality of various OER. The Open Education Network is one of many organizations that encourage textbook review as a professional development activity and part of training for instructors.
OER quality rubrics are used as part of the overall review before original publication or during revision; to assess alignment with learning outcomes; in peer-reviews of existing OER available in repositories and referatories; for evaluating an OER's accessibility and inclusivity; and to judge proposal applications and awards.
These are just examples and are not an exhaustive list:
