Reusing existing Open Educational Resources (OER) can save significant time and effort. The OPEN partners recommend TAACCCT grantees invest up-front time finding OER to reuse rather than starting development of new educational resources right away. A significant benefit of OER is that they provide source material to build your development efforts around. No need to invest development effort in creating something that already exists.
OER come in a wide variety of types. Many educators are simply looking for individual media elements to use within their courses, such as photos, graphics, videos, and audio, that are openly licensed in a way that freely permits education use.
