Take the time to watch this fantastic one-hour video by Michael Welsh (Kansas State) on The Future of Education -- I guarantee it will change the way you think about integrating technology into your teaching.
I fully echo Caron's sentiments on this video. It is superb and highlights the largely untapped potential for using web-based technology (YouTube, Wikipedia, Facebook, Twitter, Blogger, etc.) to take advantage of The Wisdom of the Crowds to turn classrooms into interactive learning laboratories.
At the end of the video, Welsh shows a simulation he and his students perform that mimics the development of an artificial world from 1450 to 2050 and beyond. I would absolutely love to see a similar simulation done in an economics course highlighting how various institutions (legal systems, political systems, cultural norms, etc.), geographies, and resource allocations can lead to vastly different outcomes for people groups over time -- similar to an agent-based model using live people in lieu of computerized agents.
Needless to say, this video has given me a ton of ideas for teaching in the future. I can't wait until I can get a classroom of my own and try to put some of these ideas into practice.
To get a preview of what the video linked to above is like, watch Welsh's earlier video, The Machine is Us/ing Us:
