Open Educational Resources (OER) consist of open-licensed educational content from a variety of educational domains. These materials include textbooks, videos, interactive elements, lecture notes, assessments, and learning guides that can be freely used, added to, revised, and enhanced. David Wiley defines OER using the 5R framework:
- Retain – make, own, and control a copy of the resource (e.g., download and keep your own copy)
- Revise – edit, adapt, and modify your copy of the resource (e.g., translate into another language)
- Remix – combine your original or revised copy of the resource with other existing material to create something new (e.g., make a mashup)
- Reuse – use your original, revised, or remixed copy of the resource publicly (e.g., on a website, in a presentation, in a class)
- Redistribute – share copies of your original, revised, or remixed copy of the resource with others (e.g., post a copy online or give one to a friend)
