Many RISD faculty already use affordable or free course materials. So what's the difference between those and OER?
Put simply, OER are published with open licensing, typically through Creative Commons. The licenses allow specific privileges to use, share, and modify the content - privileges that are not typically allowed of the below materials, which cost money to the institution and have much more restricted use.
With that said, using these are great ways to keep course costs down for students.
A variety of "open" movements have blossomed over the last several decades. Based on the idea that knowledge should be free and available to all, these movements share a spirit of community-building, thrive on digitally networked platforms, and embrace flexible Creative Commons licensing. Most of them fall under the umbrella of Open Educational Resources.
