What a great collection of resources from the commons. We used to buy educational resource video tapes at about $100 each for the school library! Needless to say it was a carefully condsiered purchase. I am now in the process of culling them from the collection.
I was thinking that the Brady Bunch clip of Time to Change might be good to show colleagues who are slow adopters of technology. I also liked the Learning to Change video from Australian Educators.
I've used YouTube at school for various resources - it is available to teachers on the network but blocked to students. I guess the aspect of teaching users to use the web responsibly remains significant - network managers can't just keep blocking everything!
