Interesting article in the New York Times:  Colleges Chase as Cheats Shift to Higher Tech, by Jonathan D. Glater:

With their arsenal of electronic gadgets, students these days find it easier to cheat. And so, faced with an array of inventive techniques in recent years, college officials find themselves in a new game of cat and mouse, trying to outwit would-be cheats this exam season with a range of strategies — cutting off Internet access from laptops, demanding the surrender of cellphones before tests or simply requiring that exams be taken the old-fashioned way, with pens and paper.
