The top students usually end up posting all their weekly homework solutions, but not the challenge problems, which are what they are graded on and get the detailed instructor feedback on.

If I were still in industry and someone came in with an M.I.T.x credential, I’d take it.” <br /><br />Time will tell.<br /><br />I expect that this will drive learning research much more than anything done by K-12 educators.

The real point of MITx is that MIT has committed to developing a model of on-line higher ed course delivery while making the software <b>open source, and freely available to other educational institutions</b>.<br /><br />That's the point where they grab the initiative in changing the game.

Rather, MIT plans to create a not-for-profit body within the Institute that will offer certification for online learners of MIT coursework. That body will carry a distinct name to avoid confusion."<br /><br /><br />This is a common marketing technique - remove functionality and call it something different. It might be a more difficult learning model, but I assume that the courses are exactly the same. The functionality is (supposed to be) the same.<br /><br /><br /><br />"What will it cost to get a credential for a given course?"<br /><br />"MIT is in the process of determining a fee structure for individual courses and groups of courses. The aim is to make credentialing highly affordable."<br /><br />If the tests and grading are the same, then how can they pretend that the degree is somehow less? They are taking your money. What does that imply legally? If the credential is somehow less, what is it less than? Is it not an official college degree? What happens if businesses think this is a way to get top people on the cheap? What if you go to a community college but do MITx on the side? What if a community college offers MITx as one of its offerings?<br /><br />What is likely to happen is that many people (who would NEVER be accepted into MIT) will get some top grades. <br /><br />Potentially, MIT can make a huge amount of money off of this, but it's a double edged sword. Accepting money also means accepting responsibility, and that means responsibility over making it very clear what the credential means. The cat will be out of the bag. Can MIT (or other colleges) not accept the credential as a legal college degree? I think accepting money changes everything.<br /><br />Get your MITx degree with help at your community college and then go to the fancy grad school. This is different because it is not just the University of Phoenix.SteveHhttps://www.blogger.com/profile/03956560674752399562noreply@blogger.com
