Were parents, teachers, administrators, so resistive to change when the slide rule, calculator, overhead were introduced in school? Were they afraid that when students learned to use a calculator they wouldn't know math any more? Maybe. Social Media and Web 2.0 Tools are just that, tools. They are the devices teachers use to teach, and students use to learn. I (and many others) see them no different from the chisel and slate, ink and hide or pencil and paper. These are just the new tools. And new tools take time getting used to.
