These days, it's not uncommon to see a baby swiping her little finger across the screen of a tablet, or a third-grader engrossed in a game on his smartphone as he walks down the street.
It seems so wrong — but do we know that it is?
Actually, we do. A new study by the London School of Economics found that schools that ban students from carrying phones see a clear improvement in test scores.
The study involved 130,000 students at 91 schools in England since 2001. Researchers found that, following a cellphone ban, overall test scores on a national exam improved by 6.4%; for underachieving students, the effect was much more drastic, as their test scores rose by 14%.
"We found the impact of banning phones for these students equivalent to an additional hour a week in school, or to increasing the school year by five days," researchers Richard Murphy and Louis-Philippe Beland told CNN.
"Schools could significantly reduce the education achievement gap by prohibiting mobile phone use in schools," they concluded.
