On 11 September Aaron Sloman gave an invited talk at the 2012 ALT Conference entitled "What is computational thinking? Who needs it? Why? How can it be learnt? (Can it be taught?)". Above is a very comprehensive Slideshare version of the talk, which is best viewed "full-screen". A video of the talk is available on the ALT YouTube channel, and I've embedded it below.
