OpenCourseWare (OCW) is an educational initiative started by MIT to provide free access to core course materials from all MIT undergraduate and graduate classes online (1). OCW aims to share educational resources freely for non-commercial purposes like research and education (2). Although counterintuitive, OCW is appropriate for a research university like MIT where ideas move quickly from the lab to classroom before textbooks are published (3). OCW is not intended as a replacement for paid distance education but as a global resource for teachers and learners.
