OER (Open Educational Resources) Commons

OER Commons is a free online library that helps teachers use open educational resources to build lesson plans and courses.

Open Educational Resources (OER) are teaching and learning materials that you may freely use and reuse at no cost, and without needing to ask permission. Unlike copyrighted resources, OER have been authored or created by an individual or organization that chooses to retain few, if any, ownership rights.

In some cases, that means you can download a resource and share it with colleagues and students. In other cases, you may be able to download a resource, edit it in some way, and then re-post it as a remixed work. How do you know your options? OER often have a Creative Commons license or other permission to let you know how the material may be used, reused, adapted, and shared.

From a single point of access in OER Commons, you can search, browse, and evaluate resources in OER Commons’ growing collection of over 50,000 high-quality OER. Here are some curated collections to start exploring:
