MIT has long offered thousands of undergrad and graduate level course materials for free online. This month, they announced plans to significantly update and expand that effort, creating an open-source education system called MITx that will basically allow anyone to virtually take an MIT class, participate in laboratories, and get individual assessment on whether or not they’ve learned the material. The school even has plans—not fully worked out yet—to offer some kind of certificate of completion to people who take classes this way and can show that they’ve mastered the subject. MITx will open in spring of 2012. I’m looking forward to checking out this great resource! (Thanks to Chris Hayden!)
