Free, online social studies courses for middle and high school: Big History, World History, World History AP and Climate. Teachers sign up and assign readings, videos and activities, with leveled articles and audio to support different readers. Students read, watch, discuss and write evidence-based claims, and courses plug into Google Classroom, Canvas and Schoology. It also runs a teacher community and free professional development.

Our take: A strong free history curriculum for teachers and co-ops; homeschool families should note the terms say it is meant for school-directed use.

Watch for

  • Analytics and ad pixels on the site

Data and privacy

The privacy policy says student data is never used for targeted advertising or sold, and schools are responsible for parent notices and consent. It uses Adobe and Google Analytics and tracking pixels to promote the site elsewhere. Read the privacy policy.

Does it work?

OER Project publishes annual research reports by its own researchers that show student writing growth, especially in Title I schools; these are not independent.
