The National Repository of Online Courses (NROC) is a library of online course content for students and faculty in higher education, high school and Advanced Placement. It’s a non-profit project of the Monterey Institute for Technology and Education, an education think tank that is well-funded by competency-based education advocates like the Bill & Melinda Gates Foundation. It also receives funding from the William and Flora Hewlett Foundation, the James Irvine Foundation and from NROC member institutions.
Hippocampus.org has video presentations and interactive activities called simulations available in history, government, sociology, and economics. These are openly available, and the content collections come from Chattanooga State University, National Geographic, Dallas Learning Solutions, the Virginia Historical Society, and Tom Christian and Thorp School District.
