M.I.T pioneered the broadcasting of classroom lectures online with OpenCourseWare (OCW), and now they’re pushing the evolution of free education one step further with M.I.T.x, scheduled for release in spring of this year. What sets M.I.T.x apart from OCW and Academic Earth, which make video lectures available online, is that it will provide a more interactive experience. Rather than just watching videos, M.I.T.x users will have access to online laboratories and self assessments, along with the opportunity to engage in discussion with each other. M.I.T.x will also offer certificates of completion for those who successfully complete the online course materials.
