Bans may help protect classroom focus, but districts need to stay mindful of students’ sense of connection, experts say

Students around the world are being separated from their phones.

In 2020, the National Center for Education Statistics reported that 77 percent of U.S. schools had moved to prohibit cellphones for nonacademic purposes. In September 2018, French lawmakers outlawed cellphone use for schoolchildren under the age of 15. In China, phones were banned country-wide for schoolchildren last year.

Supporters of these initiatives have cited links between smartphone use and bullying and social isolation and the need to keep students focused on schoolwork.

77% Of U.S. schools moved to ban cellphones for nonacademic purposes as of 2020, according to the National Center for Education Statistics

But some Harvard experts say instructors and administrators should consider learning how to teach with tech instead of against it, in part because so many students are still coping with academic and social disruptions caused by the pandemic. At home, many young people were free to choose how and when to use their phones during learning hours. Now, they face a school environment seeking to take away their main source of connection.

“Returning back to in-person, I think it was hard to break the habit,” said Victor Pereira, a lecturer on education and co-chair of the Teaching and Teaching Leadership Program at the Graduate School of Education.

Through their students, he and others with experience both in the classroom and in clinical settings have seen interactions with technology blossom into important social connections that defy a one-size-fits-all mindset. “Schools have been coming back, trying to figure out, how do we readjust our expectations?” Pereira added.

It’s a hard question, especially in the face of research suggesting that the mere presence of a smartphone can undercut learning .

Michael Rich , an associate professor of pediatrics at Harvard Medical School and an associate professor of social and behavioral sciences at the Harvard T.H. Chan School of Public Health, says that phones and school don’t mix: Students can’t meaningfully absorb information while also texting, scrolling, or watching YouTube videos.

“The human brain is incapable of thinking more than one thing at a time,” he said. “And so what we think of as multitasking is actually rapid-switch-tasking. And the problem with that is that switch-tasking may cover a lot of ground in terms of different subjects, but it doesn’t go deeply into any of them.”

Pereira’s approach is to step back — and to ask whether a student who can’t resist the phone is a signal that the teacher needs to work harder on making a connection. “Two things I try to share with my new teachers are, one, why is that student on the phone? What’s triggering getting on your cell phone versus jumping into our class discussion, or whatever it may be? And then that leads to the second part, which is essentially classroom management.

“Design better learning activities, design learning activities where you consider how all of your students might want to engage and what their interests are,” he said. He added that allowing phones to be accessible can enrich lessons and provide opportunities to use technology for school-related purposes.

Mesfin Awoke Bekalu, a research scientist in the Lee Kum Sheung Center for Health and Happiness at the Chan School, argues that more flexible classroom policies can create opportunities for teaching tech-literacy and self-regulation.

“There is a huge, growing body of literature showing that social media platforms are particularly helpful for people who need resources or who need support of some kind, beyond their proximate environment,” he said. A study he co-authored by Rachel McCloud and Vish Viswanath for the Lee Kum Sheung Center for Health and Happiness shows that this is especially true for marginalized groups such as students of color and LGBTQ students. But the findings do not support a free-rein policy, Bekalu stressed.

In the end, Rich, who noted the particular challenges faced by his patients with attention-deficit disorders and other neurological conditions, favors a classroom-by-classroom strategy. “It can be managed in a very local way,” he said, adding: “It’s important for parents, teachers, and the kids to remember what they are doing at any point in time and focus on that. It’s really only in mono-tasking that we do very well at things.”

Why Schools Should Ban Cell Phones in the Classroom—and Why Parents Have to Help

New study shows it takes a young brain 20 minutes to refocus after using a cell phone in a classroom

Photo by skynesher/iStock

Parents, the next time you are about to send a quick trivial text message to your students while they’re at school—maybe sitting in a classroom—stop. And think about this: it might take them only 10 seconds to respond with a thumbs-up emoji, but their brain will need 20 minutes to refocus on the algebra or history or physics lesson in front of them— 20 minutes .

That was just one of the many findings in a recent report from a 14-country study by UNESCO (United Nations Educational, Scientific and Cultural Organization) that prompted this headline in the Washington Post : “Schools should ban smartphones. Parents should help.” The study recommends a ban on smartphones at school for students of all ages, and says the data are unequivocal, showing that countries that enforce restrictions see improved academic performance and less bullying.

It’s a fraught debate, one that prompts frustration among educators, who say students are less focused than ever as schools struggle to enforce cell phone limitation policies, and rage from some parents, worrying about a possible shooting when they can’t get in touch, who insist they need to be able to reach their children at all times. And, perhaps surprisingly, it prompts a collective yawn from students.

In fact, students openly admit their cell phones distract them and that they focus better in school without them, says Joelle Renstrom , a senior lecturer in rhetoric at Boston University’s College of General Studies. It’s an issue she has studied for years. She even performed an experiment with her students that supports what she long suspected: Cell Phones + Classrooms = Bad Learning Environment.

BU Today spoke with Renstrom about the latest study and research.

with Joelle Renstrom

Bu today: let me get right to the point. do we as a society need to be better about restricting cell phones in classrooms it seems so obvious..

Renstrom: Of course. But it is easier said than done. It’s hard to be consistent. We will always have students with some kind of reason, or a note from someone, that gives them access to technology. And then it becomes hard to explain why some people can have it and some people can’t. But student buy-in to the idea is important.

BU Today: But is getting students to agree more important than getting schools and parents to agree? Is it naive to think that students are supposed to follow the rules that we as parents and teachers set for them?

Renstrom: I have made the case before that addiction to phones is kind of like second-hand smoking. If you’re young and people around you are using it, you are going to want it, too. Every baby is like that. They want to reach for it, it’s flashing, their parents are on it all the time. Students openly acknowledge they are addicted. Their digital lives are there. But they also know there is this lack of balance in their lives. I do think buy-in is important. But do it as an experiment. Did it work? What changes did it make? Did it make you anxious or distracted during those 50 minutes in class? I did that for years. I surveyed students for a number of semesters; how do you feel about putting your phone in a pouch? They made some predictions and said what they thought about how annoying it was. But at the end, they talked about how those predictions [played out], and whether they were better able to focus. It was very, very clear they were better able to focus. Also interestingly, not a single student left during class to get a drink or go to the bathroom. They had been 100 percent doing that just so they could use their phone.

BU Today: Should we be talking about this question, cell phones in classrooms, for all ages, middle school all the way through college? Or does age matter?

Renstrom: It’s never going to be universal. Different families, different schools. And there is, on some level, a safety issue. I do not blame parents for thinking, if there’s someone with a gun in school, I need a way to reach my kids. What if all the phones are in pouches when someone with a gun comes in? It’s crazy that we even have to consider that.

BU Today: What’s one example of something that can be changed easily?

Renstrom: Parents need to stop calling their kids during the day. Stop doing that. What you are doing is setting that kid up so that they are responding to a bot 24-7 when they shouldn’t be. If you’re a kid who gets a text from your parent in class, you are conditioned to respond and to know that [the parent] expects a response. It adds so much anxiety to people’s lives. It all just ends up in this anxiety loop. When kids are in school, leave them alone. Think about what that phone is actually meant for. When you gave them a phone, you said it’s in case of an emergency or if you need to be picked up in a different place. Make those the parameters. If it’s just to confirm, “I’m still picking you up at 3,” then no, don’t do that. Remember when we didn’t have to confirm? There is a time and place for this, for all technology.

BU Today: This latest study, how do you think people will react to it?

Renstrom: This isn’t new. How many studies have to come out to say that cured meat is terrible and is carcinogenic. People are like, “Oh, don’t tell me what to eat. Or when to be on my phone.” This gets real contentious, real fast because telling people what’s good for them is hard.

BU Today: I can understand that—but in this case we’re not telling adults to stop being on their phones. We’re saying help get your kids off their phones in classrooms, for their health and education.

Renstrom: Studies show kids’ brains, and their gray matter, are low when they are on screens. School is prime habit-forming time. You should not sit in class within view of the professor, laughing while they are talking about World War II. There is a social appropriateness that needs to be learned. Another habit that needs to be addressed is the misconception of multitasking. We are under this misconception we all can do it. And we can’t. You might think, I can listen to this lecture while my sister texts me. That is not supported by science or studies. It is literally derailing you. Your brain jumps off to another track and has to get back on. If you think you have not left that first track, you are wrong.

BU Today: So what next steps would you like to see?

Renstrom: I would like to see both schools and families be more assertive about this. But also to work together. If the parents are anti-smartphone policy, it doesn’t matter if the school is pro-policy. If there is a war between parents and schools, I am not sure much will happen. Some kind of intervention and restriction is better than just ripping it away from kids. The UNESCO study found it is actually even worse for university students. We are all coming at this problem from all different ways. Pouches or banned phones. Or nothing.

i found this very helpful with my research

It was ok, but i will say i enjoyed learning more about why we should not have cell phones.

It was a great research, helped me a lot.

I think that this was helpful, but there is an ongoing question at my school, which is, though phones may be negative to health and knowledge and they’re a distraction what happens if there was a shooting or a fire or a dangourus weather event and you don’t have a phone to tell your parents or guardians at home if you are alright? (Reply answer if have one)

Yeah they would get an amber alert

well, the school has the technology that can help communicate that to the parents, and if that were to happen, I guess that’s why there’s always a cell phone in the classrooms those old-time ones, but I feel it would not be okay in case of a shooting since you have to go silence, and on the moment of fire or weather everything happens so fast in the moment.

Yeah, that’s exactly why they have those supplies or items in the classroom, to alert parents. Kids don’t need to use their phones for that.

In schools all teachers have cell phones. So one way or the other the messages would get out to the parents as needed. If a student gets on the cell phone to inform the parent about the activity, that’s taken place it could cause panic. School staffs are informed as to how to handle such situations.. what I have seen take place in classes are students who are texting each other either in the same room or in another classroom during the school time. Many students spend time on YouTube and not concentrating what’s going on in the classroom.

Teachers have communication with all parents and it also has amber alerts

You just give the kids watches to call there parents or guardians on.

I’m a teacher. If there’s an event like this, it could be detrimental to the emergency system if too many people are calling. Also, kids don’t have the common sense to turn their ringers off. They go off in my class, more often than they should.. If there’s a shooter in any school, parents are going to be calling their kids. Phones constantly going off could lead a shooter to specific places if they can hear them. I understand the parent’s arguments as to why they want their kids to have their phones, but that very argument could lead to their child being hurt or killed in the scenario mentioned above.

I think that this was helpful, but there is an ongoing question at my school, which is, though phones may be negative to health and knowledge and they’re a distraction what happens if there is a shooting or a fire or a dangerous weather event and you don’t have a phone to tell your parents or guardians at home if you are alright?

I am writing a paper and this is very helpful thank you.

I am writing a paper and this is very helpful but it is true what if our mom or dad have to contact us we need phones!

this helped me with my school project about whether cell phones should be banned in school. I think yes but the class is saying no. I think it’s because I was raised without a phone so I know how to survive and contact my parents without a phone. but anyway, this helped me with my essay! thank you!

I don’t think phones should be allowed in school, and this is perfect backup! Thank you Doug

great infromation for debate

Thanks, this helped a lot I’m working on an essay and this has been really helpful.by the way, some people may think, but what if i need to call my mom/dad/guardian. but the real thing is, there is a high chance that there will be a telephone near you. or if it’s something that only you want them to know,go ahead and ask your teacher if you can go to the office.

I mean it could also depend on the student, like for example let’s say that i’m a student inside the school, if I used my phone and I got off it, for me it would instant focus, but for others students they might take longer or the same time as me, it all really depends if the student is tend to be responsible with their time trying to focus so I would say that this claim is not true.

I think that is article was very good. I’m currently writing and essay and I have used this for most of my evidence so far. I personally think that cellphones should be banned from the classroom because the school will get the information that your parents need out to them so you don’t have to cause a panic because you don’t know if your parents know what is going on at your school or not. It will just be better because then we wouldn’t have as many distractions in the classrooms as we do now because kids are always getting caught on their phones and they are constantly being sent down to the office and it takes time to get the class back on track. I personally agree with Doug that cellphones should be banned in the classrooms.

It’s striking to realize that the reason some parents feel the need to advocate for phone usage in school is due to concerns about a potential school shooting. While parents may be more informed about the harmful effects of smartphones in a learning environment, they take preference for the safety of their child in a hypothetical situation. It’s a hard debate because while the safety of their children is important, the drastic effects of students needing 20 minutes to refocus is significantly impacting their ability to learn in their classes. I find it very saddening that this is what our world has come to – prioritizing safety for a school shooting over academic performance, because it is no longer so unusual for a school to experience that type of tragedy.

I liked the comment, “Addiction to phones is kind of like second-hand smoking. If you’re young and people around you are using it, you are going to want it too,” because I experienced this phenomenon in my early middle school years, with the invention of the first iPhone. All of a sudden an invention that was broadcasted on the news became an essential for the other students in my middle school class, to the point where I became one of the only students without one. Then, I finally succumbed to the pressure, and begged my parents for an iPhone as I felt extremely left out. It’s frustrating to accept that this pressure is affecting children now younger and younger by the year, with even six year old children I babysit owning their own iPhone/iPad.

I also think that with the prevalence of child phone usage significantly increases parental anxiety, particularly for those parents who are already overbearing to start. Giving parents the ability to contact their child at any given time is harmful, and it can create a dependence on either side. It’s ironic given the fact that parents push their children to focus and succeed in their classes, yet harass them all day about minuscule things that could’ve been addressed later that day. So yes, parents need to stop calling their kids during the day.

this helped me with my school project, very reliable source.

I think that this talked more about why parents should help more than why cell phones should be banned.

I think the teachers or guardians will allow you to contact someone but I think after the shooting or crisis they will contact your parents or guardian from the office or person in charge

I agree, I’m 13 and I honestly could live without a phone

i also agree but parents need to reach their kids somehow if something happens in school

I’m also 13

had to research this for an assingnment and onistlly, I love my phone and I would marry it if I could!

This is really reasonable. In my school my friends have cell phones and there is a lot of drama. I am writing a report on this.

This is really good

I’ve taught high school since 1999. Should cell phones be banned? 100% Absolutley. I don’t think twice about it.

Cellphones in Schools: A Huge Nuisance and a Powerful Teaching Tool

• Share article

When Nelann Taylor lets her high school students whip out their smartphones and dive into tools like Duolingo, Quizlet, Kahoot, and Flipgrid, she knows she may be in for a classroom management headache. Some of her students “have really figured out how to self-correct and just say, ‘Well, I know that I can’t be on my own phone right now’ ” unless it is for classwork, she said. But others take advantage of the freedom to start scrolling through text messages, and Taylor has to tell them put the devices away. Cellphones are both a powerful learning tool and huge distractions for kids. Figuring out how to make the most of them is “really tricky,” said Taylor, a fan of technology in the classroom who teaches high school Spanish and web design in Louisiana’s St. John the Baptist Parish Schools. “It’s always a work in progress.” Educators like Taylor have struggled with whether to ban phones, let kids use them for classwork, or some combination of the two for more than a decade. But the need to figure out how to use cellphones for learning, rather than letting them become a distraction, has gotten more urgent since kids returned from pandemic-driven virtual learning, experts and educators say. “I think the transition from trying to learn at home using devices and having perhaps multiple devices, being distracted by them, trying to focus attention on learning, and then transition back into the classroom has been really difficult,” said Christine Elgersma, the senior editor for social media and learning resources at Common Sense Media, a nonprofit organization that focuses on children, technology, and media. There are some good practices, including having a schoolwide policy on devices that’s clearly communicated to students and parents at the beginning of the school year. Being vehemently anti-cellphone may backfire, Elgersma warned. Allowing kids to use the devices for classwork is a way to acknowledge that, “these are really cool tools, and that some of what kids are doing on their phones is really impressive and creative and important to them,” she said. “We don’t want to discount how woven into the fabric of their lives these devices are.” At Kansas’ Springhill Middle School, students are expected to put their phones in their lockers as soon as school begins, and not take them out until the end of the day, unless a teacher plans to use the devices in a lesson, said Trevor Goertzen, the school’s principal. A National Association of Secondary School Principals digital principal of the year, Goertzen is a champion of tech in the classroom. But he thinks it’s too easy for kids to get distracted by entertainment or social media if they have access to their phones all day. All his students have MacBooks, he said, which can be used for just about any classroom activity requiring a device. Teachers have permission to allow cellphones occasionally for specific purposes, but “most teachers realize it’s not worth opening the door for them to use their phones.”

‘Teach kids to manage their technology’

But Stevie Frank, a 5th grade humanities teacher at Zionsville West Middle School in Whitestown, Ind., views cellphones as a great student engagement tool. Her students can keep their phones with them during class, as long as they have notifications turned off, so they’re not interrupted by a dinging noise. And she incorporates them into her class assignments. For instance, Frank sets up stations around the room where kids read passages and tackle questions on, say, an author’s purpose. To check to see if their answers are right, students use their phones to scan a QR code, and up pops a video of Frank explaining the correct answer. “It’s one of those things where I was like, ‘How can I be at 12 stations at once?’ ” Frank said. “And I’m like, ‘Wait a minute, I can!’ ” Frank’s students also use their phones to record podcasts, since they tend to have better microphones than school-issued devices do. Recently, for instance, she had groups of students choose books about different identities and then create a podcast exploring themes that the text raised. One group picked a book about a person experiencing homelessness and interviewed a staffer at a local shelter for their podcast. Naturally, there are times when students use their cellphones to go off task, Frank said. But that’s all part of the lesson. She said kids need to figure out how to voluntarily distance themselves from their devices. “You’ve got to teach the kids how to manage their technology and if we’re not going to do it in school, where’s it going to be done?” Frank said. A certified yoga teacher, she’s talked to her students about mindfulness, the importance of being present in the moment, and how technology can distract from those things. If a kid has a particularly tough time putting their phone away, or keeps getting distracted while using a school laptop, Frank will ask if they’d rather have a paper copy of the assignment, or if they’d like to put their phone on their desk. Giving students the choice to disengage from their phones helps “get their buy-in,” Frank said. “They’re like, ‘yup, I need to do that.’ ” Another advantage of using a phone for class assignments: Students are already familiar with how they operate, said Kristin Daley Conti, a science teacher at Tantasqua Regional Junior High School in central Massachusetts. Her attitude on cellphones in school is essentially, “if you can’t beat ‘em, join ‘em.” So if her students want to use their phones to, say, time how long it takes ice to melt, she’s fine with that. Many of her students also used the cameras on their phones for a project last year on ecosystems. Students chose an outdoor area near the school and took pictures of the spot once a week, then looked at how the biodiversity in its ecosystem changed over time. Students snapped photos of flowers, squirrels, plants, insects, frogs, and more and then shared them in a digital journal that was also accessible to parents. Daley Conti’s advice to teachers who are considering using cellphones in their classroom: Listen to kids’ ideas. Ask them questions like, “Do you think we’re using our phones too much?” or “Could we use our phones in class responsibly?” “If you’re thinking about incorporating cellphone use, hear from the experts,” she said.

Mobile phones are currently banned in all Australian state schools and many Catholic and independent schools around the country. This is part of a global trend over more than a decade to restrict phone use in schools.

Australian governments say banning mobile phones will reduce distractions in class , allow students to focus on learning , improve student wellbeing and reduce cyberbullying .

But previous research has shown there is little evidence on whether the bans actually achieve these aims.

Many places that restricted phones in schools before Australia did have now reversed their decisions. For example, several school districts in Canada implemented outright bans then revoked them as they were too hard to maintain. They now allow teachers to make decisions that suit their own classrooms.

A ban was similarly revoked in New York City , partly because bans made it harder for parents to stay in contact with their children.

What does recent research say about phone bans in schools?

We conducted a “scoping review” of all published and unpublished global evidence for and against banning mobile phones in schools.

Our review, which is pending publication, aims to shed light on whether mobile phones in schools impact academic achievement (including paying attention and distraction), students’ mental health and wellbeing, and the incidence of cyberbullying.

A scoping review is done when researchers know there aren’t many studies on a particular topic. This means researchers cast a very inclusive net, to gather as much evidence as possible.

Read more: Why a ban on cellphones in schools might be more of a distraction than the problem it’s trying to fix

Our team screened 1,317 articles and reports as well as dissertations from masters and PhD students. We identified 22 studies that examined schools before and after phone bans. There was a mix of study types. Some looked at multiple schools and jurisdictions, some looked at a small number of schools, some collected quantitative data, others sought qualitative views.

In a sign of just how little research there is on this topic, 12 of the studies we identified were done by masters and doctoral students. This means they are not peer-reviewed but done by research students under supervision by an academic in the field.

But in a sign of how fresh this evidence is, almost half the studies we identified were published or completed since 2020.

The studies looked at schools in Bermuda, China, the Czech Republic, Ghana, Malawi, Norway, South Africa, Spain, Sweden, Thailand, the United Kingdom and the United States. None of them looked at schools in Australia.

Academic achievement

Our research found four studies that identified a slight improvement in academic achievement when phones were banned in schools. However, two of these studies found this improvement only applied to disadvantaged or low-achieving students.

Some studies compared schools where there were partial bans against schools with complete bans. This is a problem because it confuses the issue.

But three studies found no differences in academic achievement, whether there were mobile phone bans or not. Two of these studies used very large samples. This masters thesis looked at 30% of all schools in Norway. Another study used a nationwide cohort in Sweden . This means we can be reasonably confident in these results.

Mental health and wellbeing

Two studies in our review, including this doctoral thesis , reported mobile phone bans had positive effects on students’ mental health. However, both studies used teachers’ and parents’ perceptions of students’ wellbeing (the students were not asked themselves).

Two other studies showed no differences in psychological wellbeing following mobile phone bans. However, three studies reported more harm to students’ mental health and wellbeing when they were subjected to phone bans.

The students reported they felt more anxious without being able to use their phone. This was especially evident in one doctoral thesis carried out when students were returning to school after the pandemic, having been very reliant on their devices during lockdown.

So the evidence for banning mobile phones for the mental health and wellbeing of student is inconclusive and based only on anecdotes or perceptions, rather than the recorded incidence of mental illness.

Bullying and cyberbullying

Four studies reported a small reduction in bullying in schools following phone bans, especially among older students. However, the studies did not specify whether or not they were talking about cyberbullying.

Teachers in two other studies, including this doctoral thesis , reported they believed having mobile phones in schools increased cyberbullying.

But two other studies showed the number of incidents of online victimisation and harassment was greater in schools with mobile phone bans compared with those without bans. The study didn’t collect data on whether the online harassment was happening inside or outside school hours.

The authors suggested this might be because students saw the phone bans as punitive, which made the school climate less egalitarian and less positive. Other research has linked a positive school climate with fewer incidents of bullying.

There is no research evidence that students do or don’t use other devices to bully each other if there are phone bans. But it is of course possible for students to use laptops, tablets, smartwatches or library computers to conduct cyberbullying.

Even if phone bans were effective, they would not address the bulk of school bullying. A 2019 Australian study found 99% of students who were cyberbullied were also bullied face-to-face.

What does this tell us?

Overall, our study suggests the evidence for banning mobile phones in schools is weak and inconclusive.

As Australian education academic Neil Selwyn argued in 2021 , the impetus for mobile phone bans says more about MPs responding to community concerns rather than research evidence.

Politicians should leave this decision to individual schools, which have direct experience of the pros or cons of a ban in their particular community. For example, a community in remote Queensland could have different needs and priorities from a school in central Brisbane.

Mobile phones are an integral part of our lives. We need to be teaching children about appropriate use of phones, rather than simply banning them. This will help students learn how to use their phones safely and responsibly at school, at home and beyond.

Why Schools Are Racing to Ban Student Phones

As the new school year starts, a wave of new laws that aim to curb distracted learning is taking effect in Indiana, Louisiana and other states.

Cellphones have become a school scourge. More than 70 percent of high school teachers say student phone distraction is a “major problem,” according to a survey this year by Pew Research .

That’s why states are mounting a bipartisan effort to crack down on rampant student cellphone use. So far this year, at least eight states have passed laws, issued orders or adopted rules to curb phone use among students during school hours.

The issue isn’t simply that some children and teenagers compulsively use apps like Snap, TikTok and Instagram during lessons, distracting themselves and their classmates. In many schools, students have also used their phones to bully, sexually exploit and share videos of physical attacks on their peers.

But cellphone restrictions can be difficult for teachers to enforce without schoolwide rules requiring students to place their phones in lockers or other locations.

Now state lawmakers, along with some prominent governors , are pushing for more uniform restrictions in public schools.
