Washington Post: A paper published recently in the journal Child Development reaches an interesting and perhaps counterintuitive conclusion: Children’s use of Facebook, computer games, and other online diversions doesn’t impair academic progress; on the contrary, in some cases computer use improves children’s test scores. The study, which entailed tracking 1000 children who were ages 6–12 in 1997 and ages 12–18 in 2003, was carried out by Sandra Hofferth, a family science professor at the University of Maryland and director of the Maryland Population Research Center.
