MIT OpenCourseWare (OCW) has grown from that bold idea to an unparalleled educational resource that has benefitted millions around the world and has inspired a global movement. As it stands, it includes the core teaching materials—from syllabi, lecture notes, assignments to exams. These come from 2,180 of MIT’s undergraduate and graduate courses. The MIT faculty provide educational materials to OCW voluntarily; these gifts often represent a lifetime of scholarship and teaching. The website contains more than 80,000 resources, including documents, simulations, animations, sample code and thousands of hours of classroom instruction on video. The courses have also been translated into several languages including Chinese Spanish, Portugese and Thai. MIT OCW has inspired a consortium of leading universities from around the world to share materials from thousands of their own courses. To date, over 170 million individuals have accessed the content.
