    The Khan Academy does not deserve its accolades.   The math videos are poorly done and are full of mistakes.  I don’t care how many bells and whistles you stick on bad teaching, if your videos tell students that “two plus itself times one” is … two… (last time I checked, 2 + 2 was 4) — you’ve lost me. That’s just one of many mistakes that are in almost every video.  
         Video is a great opportunity for helping students make video connections ( see http://www.youtube.com/watch?v=6Un9eAM3yzo&feature=relmfu — 1:52 starts the good stuff… and that’s from 1992… )  but Khan doesn’t bother with that silliness, or with doing things in any kind of sequence — you’d better be able to do algebra with variables on the bottom if you’re going to figure out averages (and, by the way, 4 x 83 is a “sum”).  
        I hope these videos have higher standards.
