OCW Innovations


In 1999, MIT Faculty considered how to use the Internet in pursuit of MIT's mission—to advance knowledge and educate students—and in 2000 proposed OCW.

Today, MIT OpenCourseWare is a cornerstone of MIT's ongoing commitment to openly sharing educational resources. OCW continues to grow, with more new and updated courses, more video and interactive resources, and enhancements like OCW Scholar and OCW Educator. As the online options for learners and teachers continue to multiply, the value of MIT OpenCourseWare—free and open materials spanning the entire MIT curriculum—has never been greater.
