Really nice piece in the Washington Post looking back at edX’s first year, and forward at what’s coming up, including the Mechanics ReView MOOC from MITx:

One MITx course to keep an eye on is Mechanics ReView, a physics MOOC just posted on edX. MIT officials say it has extremely well-developed, pre-vetted questions — refined over a period of years — to help students master what can be tough material.
“We’ve been able to measure the difference this approach makes,” MIT Professor David Prichard, who developed the course, said in a statement. “We can see that the students move from a focus on formulas to a focus on underlying concepts, and develop better strategies for solving problems. And this is a skill that leads to significantly better performance in their next physics course.” Read more.
