Here's a great video of Salman Khan explaining that segment of the teacher dashboard at TED. It's a great perspective on learning and (in the context of the topic I wrote about) failure. [VIDEO]

> We spend an hour learning a concept, and only practice using it when we get home. This is why I'm a fan of what the Khan Academy[1] is striving to do. It flips this pattern around, with more instruction at home and practice when with the instructor. The teacher can then spend less time introducing a topic and instead working through the process with individual students. Watching Khan's TED talk[2] is pretty inspiring. [1]: [LINK] [2]: [VIDEO]

Brazil here, I always have been trying to get excited with subjects that i learn. Thats when it gets easier to be an autodidact. So, my way to get things cool its to visualize them. from my entire hight school i've been doing that, for example: [LINK] [LINK] [LINK] [LINK] [LINK] yet, still doing that on computer college [LINK] on hight school days, i even got an friend on C++ who used to compete with me. not really compete, because we would won nothing for it. instead, we colaborate. because when you compete, you can just bring your 'enemy down', to get better than him. ok, khan's struct is well-known. [VIDEO] I really always wanted to make an website where you could just do apps, basead on your classes, doodling or whatever. if i do that, i would aim on education, website internally. really running for it. and, wolfram's about programming + education [LINK] cheers!
