After viewing this video I logged into Khan academy to check out the practice tracking features highlighted in the video. Mainly I wanted to see the categorical branching of subjects that they showed.
Its a pretty amazing idea and execution. From one basic subject, addition, they expand and branch out all the way down to basic calculus. It would be really amazing if they continued expanding this out to the point where all subjects where mapped out, even the less mathematical ones. Just to see the path from addition to trigonometry is a pretty good refresher of what the mechanics of the trig functions actually entail. Imagine seeing the path from addition to linear algebra.
More to the point, imagine a world in which a student uses this system throughout their educational career. I can't even fathom the difference that that level of tracking and relational mapping between ideas would have on a students understanding of material and motivation to tackle new subjects.
