Are cell phones hurting our children's education? Researchers at the London School of Economics, the University of Texas, and Louisiana State University looked at the impact of cellphones on student performance and when cell phones are banned, grades go up. 

This new study looked at 91 schools in four cities in the U.K. (Birmingham, London, Leicester and Manchester) before and after cellphone bans. Next, researchers looked at the test scores of teens at each of the schools. Researchers then were able to determine if cellphone bans helped grades.

Across the board, teens' test scores increased by 6 percent after phone bans were implemented. The results were even better for kids who were struggling academically; their scores improved by 14 percent after the ban.

The cellphone ban did not affect the test scores of high-achieving students nor did it change the scores for the 14-year-olds, the youngest teens evaluated. Researchers think this is because high-achieving students have already learned how to focus and avoid distractions, while 14-year-olds may be less likely to own and use phones as often as their 16-year-old peers."
