HippoCampus.org is a free, core academic web site that delivers rich multimedia content—videos, animations, and simulations—on general education subjects to middle-school and high-school teachers and college professors, and their students, free of charge. Teachers project HippoCampus content during classroom learning and assign it for computer labs and homework. Students use the site in the evenings for study and exam prep. Users do not need to register or log in to use the site.
As an open resource for personalized learning, HippoCampus.org was designed as part of a worldwide effort to improve access to quality education for everyone. HippoCampus is powered by The NROC Project, a non-profit, member-driven project focused on new models of digital content development, distribution, and use. NROC makes editorial and digital engineering investments in the content to prepare it for distribution by HippoCampus.
