Facebook and education

Hi,

I saw a news about a study examining the effect of Facebook on Grade (sounds like the study presented in AERA). It is interesting, but the result is within expectation.

I think one contribution from this research is that Facebook does take up valuable study time from college students.

So? What is the next question?

One piece of statistics is quite interesting: the Facebook users spend 1-5 hours a week studying comparing to non-Facebook users spending 11-15 hours a week studying. Does it mean that Facebook took students 10 hours a week of studying time? I guess probably not. Those students will still find other ways to kill time. But, what really contributing the differences?
