It's funny that you posted that. I had just used it in a presentation I made in a class that I am taking. It was written by a teacher named Karl Fisch at Arapahoe High School in Littleton, Colorado and has made it's way around the Internet.
Here's a link to an URL that has some other presentations he wrote. The What If PowerPoint is about teacher's reactions to "new innovations" in education.
Wow-both links are very interesting. It's especially interesting/challenging to think that we're educating our kids for jobs that don't even exist yet.
