The amount of time spent on Facebook at each log-in varied from just a few minutes to more than an hour. 　　The Ohio report shows that students who used Facebook had a“significantly”lower grade point average—the marking system used in US universities—than those who did not use the site. 　　“It is the equivalent of the difference between getting an A and a B, ”said Karpinski, who will present her findings this week to the annual meeting of the American Educational Research Association.
