Clearly, what goes around comes around. I used to do homework on the schoolbus (we won’t go into how long ago), and now – since so much homework involves the Internet, apparently – students can now do homework on schoolbuses. IF they’re Wi-Fi-enabled, of course. And the Internet’s presence, interestingly, on the bus seems to be having a calming effect – see “Wi-Fi Turns Rowdy Bus Into Rolling Study Hall” in the New York Times. “Behavioral problems [offline ones, anyway] have virtually disappeared,” it adds, since a school in Vail, Ariz., “mounted a mobile Internet router to bus No. 92’s sheet-metal frame.” Now they’re going to have to train bus drivers in digital citizenship instruction too!
