The second video I saw a while back, and actually posted on my blog to start this school year, (linked to my name above). In that post I said,
What excites me about web2.0 tools is not the tools themselves, but the ability of these tools to actively engage students in their learning. Students are often far more capable of leading their own learning than we give them credit for.
Let’s make sure we help them soar rather than clipping their wings.

Thanks for putting these two videos together in one place, they work well together!
