Since I'm brushing up on my science lately, the BBC Click show presented the Khan Academy as a new form of educational tool that is picking up in popularity across a few countries, including America where education budgets are under pressure.
At the time of writing, the Khan Academy has 162,092,289 lessons delivered via YouTube, that is... a lot.
I watched a few videos and I like his style of teaching, its all unscripted and greatly in-depth but not to the point you go "bwuh?"
Oh, and it keeps track of the stuff you watched, quizzes you and uses 'gamification' to encourage more learning! That is a major plus my end.
