Thinking About Smartphone Bans in Schools | American Enterprise Institute– www.aei.org

America’s war on student smartphones is intensifying. Roughly two-thirds of US states have moved to restrict phone use in schools. The educational logic is straightforward enough. If these devices distract our kids, lock the gadgets away and learning will naturally improve—a strong prima facie case, to be sure. Yet new nationwide evidence suggests the story is more complicated than this basic common parental and teacher intuition.

A fresh NBER working paper by Stanford University’s Hunt Allcott and co-authors, “The Effects of School Phone Bans: National Evidence from Lockable Pouches,” examines one of the most stringent approaches—lockable phone pouches that physically prevent access during the school day. Using a dataset spanning thousands of schools, the researchers take advantage of a kind of natural experiment by comparing outcomes before and after adoption against similar schools that didn’t adopt the policy.

If the goal is to keep kids off their phones while at school, mission accomplished. On those terms, the policy works. Phone use plunges with pouches—fewer GPS pings on campus and far less in-class use, according to teachers.
