From a comment at a Slashdot discussion on the use of WiFi in classrooms:
How they handle it at Harvard Business School (jwachter) on Saturday November 19, @01:53PM :
I’m a student at Harvard Business School, where they have a fairly interesting solution for handling this problem. While every campus building has wireless access, all the access points in the classroom buildings require a web based log-in that checks your student ID versus your class schedule. If you’re scheduled to be in class at that moment, you are denied wireless access to the internet (in any classroom building).
Draconian, perhaps, but very effective at keeping us focused in class.
Case teaching at HBS is a pretty intense experience, but this access system surprises me. – I have always held that if you cannot get the students to concentrate in class because they are surfing, then you don’t have a technical problem. This means students cannot google for updated information while in class, which I see as useful, not disturbing. Anyway, another person further down nails it:
[Georgia] Tech has a good solution to this problem too: they let you do whatever you want, but if you don’t understand the material they fail you and kick you out. It’s effective at keeping us focused (enough) in class, and also isn’t draconian. (mrchaotica)
