Minor Thoughts from me to you

Using math and computer science concepts decidedly more advanced than most of those in Khan’s video library, the Khan engineers have trained the website’s exercise platform how to predict, with startling accuracy, how likely it is that a student will correctly answer the next practice problem -- and whether that student will be able to solve the same type of problem a week, two weeks, and a month later.

An interesting look at how the Khan Academy is trying to use their platform to predict how well someone actually knows a concept, instead of just knowing how well that person did on one test or drill.

In the future, they'd like to be able to create a whole new credentialing system—a way for employers to know what a candidate really knows instead of just knowing what school a candidate went to and what the candidate might know.
