Finding OER - Places to Start
There are a multitude of OER available online to choose from, including full textbooks and courses, lessons and units, multimedia resources, and data. These can be found through a search of popular search engines like Google, though it is easier to search and discover them through dedicated OER repositories or libraries. Below is a sampling of such repositories and libraries.
Aggregated OER Collections
- Hippo Campus - Multimedia content on general education subjects for middle-school and high-school teachers and their students.
- Khan Academy - Short lessons in the form of YouTube videos and practice exercises.
