MIT is a pioneer in the open learning movement, and they continue to blaze trails. One of the drawbacks of open course material has been a lack of context or logical progression needed for the self-directed learner. So they’ve launched Scholar courses:
OCW Scholar courses are designed for independent learners who have few additional resources available to them. The courses are substantially more complete than typical OCW courses and include new custom-created content as well as materials repurposed from MIT classrooms. The materials are are also arranged in logical sequences and include multimedia such as video and simulations.
