Bill Chamberlain's last post dealt with this same issue. We are doing our students a disservice if we don't keep up with current practices and current technologies. The University of Southern Alabama, and in particular Dr John Hadley Strange, is doing it's part to send teachers out into the 'real world' armed with these tools.
Dr Strange's course deals with using technology to engage students in learning. His teaching students have direct contact with school students throughout the world through classroom blogs, while learning to use new technologies at the same time. His students learn about Twitter, iGoogle, shared calendars, and MANY other important web 2.0 tools.
The video below, is Dr Strange's introduction to his course. If we could duplicate this sort of education as in-service training for our practicing teachers, it would be a very good thing!
