As kids head back to school, many schools aren’t allowing them to bring their phones to class. Legislation to ban phones in schools has been proposed or passed in many cities and states. Most schools already have policies prohibiting them for nonacademic use, according to the National Center for Education Statistics.
Parents often question these policies because they want to be able to reach their kids in an emergency such as a school shooting.
Yet research suggests it’s not just a good idea for kids to put their phones away while in class — they shouldn’t bring them to school at all.
Some 97% of 11- to 17-year-olds use their phones during school time, for an average of 43 minutes, according to a 2023 Common Sense Media study. If they’re checking their phones between classes or at lunch and recess, they’re likely preoccupied with what they’re seeing on their screens and therefore spending less time talking, playing or even just hanging out with their friends.
Such preoccupation is not healthy because, as social psychologist Jonathan Haidt wrote in “The Anxious Generation: How the Great Rewiring of Childhood is Causing an Epidemic of Mental Illness,” one of the most important things young people should be doing is playing with peers.
In doing so, they learn to navigate social dynamics and build skills by figuring out how to do different activities. It teaches them they can handle other challenges they’ll face in the future, which Haidt said can help protect them from anxiety.
Smartphones aren’t making kids smarter
But phones aren’t just intruding on kids’ time outside class. In a June Pew Research Center survey, 72% of public high school teachers said cell phone distractions are a major problem in their classrooms. If children are sneaking peeks at their phones, they can’t possibly be paying attention to what they’re supposed to be learning. A wide body of evidence tells us the human brain can’t multitask — we can only do one thing at a time.
One indicator that students aren’t learning as much at school as they did in the pre-phone era is scores on the ACT — a standardized test that measures whether they have the English, reading, math and science skills needed for first-year college courses. Last year, ACT scores dropped to the lowest level in more than 30 years, according to the organization that administers the test.
As a professor who has taught at five universities since 2010, I’ve witnessed this trend myself. When I first started teaching, before smartphones became ubiquitous, many of my students arrived better able to concentrate and work through long reading passages than they are now.
