I wish other school boards tried this approach that Los Altos has taken. And you don't need expensive Macs to use Khan Academy. It's really a revolution in education. My son has been using this site for the last few months and we've developed a reward program called "Homework Happiness" from the points he gets on Khan Academy. He can redeem the points for prizes of various levels, and he can save up for the really really big prizes too. It's clear that in our technologically immersive culture, that learning like this and having teachers use technology to help can help not only the smart kids but also kids that need help to get ahead. Khan Academy lets each child have a personalized experience, assisted by their parent(s) or teacher(s).
