“Could you repeat the question?”
No, this isn’t about that sort of lap-dancing, as distracting as it might be.
There’s an article, in today’s online Washington Post, from a Georgetown law professor explaining why he has banned computer laptops from his classroom. It’s worth reading. (It would be worth reading even if the author’s first name weren’t one I’m attached to.)
I’ll quote his conclusion.
I am sure that the Internet can be a useful pedagogical tool in some settings and for some subjects. But for most classes, it is little more than an attractive nuisance. Technology has outstripped us on this one, and we need to reassess its appropriate and inappropriate role in teaching. The personal computer has revolutionized our lives, in many ways for the better. But it also threatens to take over our lives. At least for some purposes, unplugging may still be the best response.
