couple of points

This is worth a look.
I liked the warmth with which Mike spoke about his students and the enthusiasm for the potential represented by an audience of 400 students. How to unleash that though - keeping them all engaged in the project would be fun in our current context.
I agree that students, as savvy as they may be with facebook/flickr/whatever, are essentially not particularly good at using them for 'these kinds of things' (i.e. learning). Interesting he wants to reduce the ratio of marks given to 'tests' - assessment is everything. If the 'devices' he's talking of could actually track the collaborative activity of students then perhaps that could be assessed.
But the stuff about learning to question is not new (or shouldnt be!). And 'we-learning'? please?!!?
