It’s an absolutely free gift from MIT to the global community—or at least those who have access to the Internet: MIT’s visionary Open Course Ware (OCW) website offers free content from over 1900 MIT courses for the edification and education of humankind, including course descriptions, syllabi, calendars, reading lists, assignments, answer keys, study materials, exams, lecture notes, video lectures and “related resources” that the instructor hopes will supplement the course material. It’s a truly visionary resource that embraces the philosophy of open access. However, the content itself hasn’t been adapted for use outside the classroom, so it can be difficult for the casual online student to understand how best to interact with the materials.
