Schools should ban smartphones. Parents should help.

In educational settings, smartphones have an almost entirely negative impact: Educators and students alike note they can fuel cyberbullying and stifle meaningful in-person interaction. A 14-country study cited by UNESCO found that the mere presence of a mobile phone nearby was enough to distract students from learning. It can take up to 20 minutes for students to refocus.

Education Department data suggest that a majority of schools prohibit nonacademic cellphone use during school hours, but the enforcement of those policies is often lax — teachers can’t confront every student or confiscate every device; some report students request bathroom breaks to check their notifications in the stalls. Phones are still in hand between classes, at lunch and recess, and often during instructional time despite putative bans — 97 percent of teens report using their phones during the school day, mostly for nonacademic purposes.

Forty-three percent of 8-to-12-year-olds own a smartphone, as do 88 percent of teens 13 to 18, according to the 2021 Common Sense Census. But most didn’t buy one themselves. The most ardent opponents of all-day device bans tend to be parents. Some are “enraged,” as one mother in Charlottesville told the Daily Progress, at the idea of cellphone limitations, insisting on the need to remain in contact with their children: to arrange pickups and dropoffs, keep track of their whereabouts or otherwise be in touch.

These are not totally trivial concerns. Indeed, parents and students these days have to worry about staying connected in the event of a school shooting. (As one nervous eighth-grader told a Post reporter: “I’m afraid that if something happens, I won’t be able to contact anyone. … Worst-case scenario: You can at least say goodbye.”) For the most part, though, it’s safer for students to focus on their surroundings during a crisis, not devices. The better solution to this tragic dilemma is prevent shootings in the first place with common-sense gun control policies.

For less dire — and far more common — emergencies, students would be better served by learning how to deal with a forgotten assignment or extracurricular themselves. And if there’s a true need to communicate with home, there’s always the option of using the school office’s landline, as students have done for decades.

Cellphones are a technology that seemed benign, if not marvelous, when first popularized in educational settings — one more tool with which to navigate an increasingly digital world. But new information has since emerged, and the earlier assumptions are crumbling under the weight of experience. After more than 15 years — the first iPhone launched in 2007 — there is still a lack of robust data to suggest that digital technology inherently adds value to education, said UNESCO in its 2023 Global Education Monitoring Report. Much of the research that does exist was funded by private companies trying to create a market for their own digital learning products.

The same UNESCO report calls for a ban on smartphones at school no matter what age the user, and recommends it worldwide. This would reinforce a “human-centered” vision of education, the report says. Countries that have already adopted such policies have seen positive results; reductions in bullying in Spain and improved academic performance in Norway and Belgium. The United States would do well to follow their lead.

In the face of today’s evidence, one could plausibly argue that children shouldn’t have access to smartphones at all. But at least keeping the devices out of schools? It’s an idea whose time has come.
