I'm an administrator at a large high school in an organization that content filters almost everything of potential value. (it's ironic that our students cannot access iTunes U to get Chemistry lectures from UC Berkeley in the classroom but they can access ebay and a Las Vegas gambling rewards page. I wonder if there would be to much of an outcry among the office weasels if those sites were blocked as well) One of the things that I am observing outside the school is how many of our teachers (as well as students) are using Facebook. I was actually able to set up a training during Spring Break using Facebook as a back-channel communications tool when our teachers were scattered all over the country. Why are we asking students (and staff) to step back into the previous century when they arrive at the schoolhouse door?
