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.
That the content under consideration covers the subject area appropriately
That the content of the OER is accurate and free of major errors and spelling mistakes
That the license of the content can be used or altered for the course's needs
That the OER is clearly written and appropriate for the students' level of understanding
That the accessibility of the content is appropriate for all students
Examples of rubrics for evaluating OER are available below:
Achieve.org has developed a rubric with 8 core principles found in high quality OER.
Besides their general quality, the accessibility of OER is also an important factor to consider, especially in light of the online nature of most OER. Information about creating and evaluating the accessibility of OER is listed below.
The goal of the Accessibility Toolkit is to provide the resources needed so that each content creator, instructional designer, educational technologist, librarian, administrator, teaching assistant, etc. has the opportunity to create a truly open and accessible textbook.
