Open Educational Resources (OER) are educational materials that are freely and openly available to anyone to use, reuse, revise, repurpose, remix, and redistribute. See other definitions here.
How to Use Open Educational Resources (a self-paced workshop by Open Washington)
OER means that a resource is available free of cost and that five permissions (called the "5Rs") are also available free of cost.
These permissions include:
|Retain||Make and own copies|
|Reuse||Use in a wide range of ways|
|Revise||Adapt, modify, and improve|
|Remix||Combine two or more|
|Redistribute||Share with others|

Broadly defined, an open license is a license that grants permission to use, re-use, and redistribute a work with few or no restrictions. Creative Commons licenses are most widely used by OER creators. You may freely use materials released under the Creative Commons (CC) licenses as long as you follow the license conditions, which offer various degrees of openness. CC BY is the most open license.
