Rubric to Evaluate Open Educational Resources for Learning

The Open Educational Resources (OER) are digital materials with the characteristic of being accessible for educators and for users who wish to use them or reuse them to learn about a specific topic, to teach or for research. The characteristic of being open allows the freedom to use them, study the content and apply the knowledge acquired through them, in addition to redistributing them and making changes or improvements. The OER include different web formats, such as audio, video, images, text that can be modified, redistributed and used for learning about a specific topic, however, it is pertinent to have an OER assessment instrument with content validity. The rubric has 31 criteria, each with three levels of performance, developed from a documentary search on relevant aspects to include in a learning object. Six expert judges were contacted who decided whether each criterion was essential, useful but not essential or not necessary, based on this, the Content Validity Reason was calculated.
