THIS JUST IN! Morning fresh news: We got a sneak peek at the very promising preliminary assessment data from the Envision summer pilot. True, the sample size is small and the experimental methods wouldn't pass peer review. (Sorry, Jack West!) But the A:B contrast (class taught with Khan vs. class taught by the same teacher without Khan) is intriguing. Get the full scoop at blendmylearning. A fuller "lessons learned" guide should be coming soon thereafter. Thanks to EdSurge friend Leonard Medlock, entrepreneur and Tweeter at @thelock85 and @barupmobi.
