How Phone Bans Are Changing Classrooms

April 03, 2026 / 12:09

This episode features Angela Duckworth discussing the impact of cell phone policies in schools, teacher satisfaction, and student mental health.

Angela Duckworth, a professor at the Wharton School, shares insights from her ongoing research on cell phone usage in schools. She highlights how stricter policies are being adopted by school districts across the United States.

Duckworth mentions that teachers report higher satisfaction in schools with stricter cell phone policies. The research indicates that when students are not allowed to use their phones during class, they are less likely to engage in non-academic activities.

She also addresses the mental health implications of cell phone usage among students, noting a decline in face-to-face interactions and the potential for increased anxiety and depression in young people.

Finally, Duckworth emphasizes the role of parents in influencing their children's environment and the importance of local actions to counteract broader cultural trends regarding technology use.

TL;DR

Angela Duckworth discusses cell phone policies in schools and their effects on teachers and student mental health.

12:09
00:00:00
We know the value but also the impact
00:00:02
that cell phones have on our kids. And
00:00:05
this past year saw numerous school
00:00:07
districts announcing new rules about
00:00:11
preventing the use of cell phones by
00:00:13
kids, by students during the school day.
00:00:16
With those in place, what does that mean
00:00:18
for how the dynamics of the school day
00:00:21
are going for students? That research is
00:00:23
being conducted by our guest today,
00:00:25
Angela Duckworth, along with a group of
00:00:27
her colleagues. It is a phones in focus
00:00:30
study. Angela is professor of
00:00:32
operations, information, and decisions
00:00:34
here at the Wharton School, as well as
00:00:36
co-director of the Behavior Change for
00:00:38
Good Initiative. Angela, great to catch
00:00:40
up again. How are you? Hi, good to see
00:00:43
you. I'm very happy to have this
00:00:44
conversation.
00:00:46
Yeah, so this is the second conversation
00:00:48
we're having on this topic as this
00:00:50
research continues to develop. Let me
00:00:52
circle back for people that didn't join
00:00:53
us the first time and talk about what
00:00:56
was the basis behind doing the research
00:00:58
into this in the first place.
00:01:00
I'm a psychologist who's been studying
00:01:03
self-control and grit and achievement
00:01:05
for her entire career. I'm also a former
00:01:08
high school and middle school math
00:01:10
teacher. And finally, I'm a mom. I have
00:01:12
two daughters who are now in their early
00:01:14
20s. And for all of those reasons, I
00:01:17
felt called really to do a study on cell
00:01:20
phones and in particular cell phones and
00:01:23
young people in schools. My own daughter
00:01:25
said, "Mom, you know, this is what you
00:01:27
trained for. Like your whole life you
00:01:29
learned to become a social scientist to
00:01:30
help kids. So you have [snorts] to study
00:01:32
what's going on with kids and phones
00:01:35
and in particular academic and academic
00:01:38
achievement, I should say. When we talk
00:01:39
about schools, it's not just academic
00:01:40
achievement. It's also social social
00:01:42
development. You know, what effect
00:01:44
having phones with you all the time has
00:01:46
on your ability to develop friendships
00:01:49
or you know, relationships with mentors
00:01:51
like teachers.
00:01:53
Okay, so with these school districts
00:01:55
that are obviously changing these rules
00:01:57
and trying to make sure that students
00:02:00
aren't relying on their cell phones
00:02:01
during the school day, what are we
00:02:03
starting to see in terms of how that
00:02:06
daily relationship is working not only
00:02:08
with their classmates, but I think with
00:02:10
the teachers as well.
00:02:12
We have a survey. It's still live. And
00:02:14
so if you're listening to this
00:02:15
conversation and you know or you are a
00:02:17
school teacher in a US public K-12
00:02:21
school, you're welcome to take the
00:02:23
5-minute survey at phonesinfocus.org.
00:02:26
Here's what we're learning. We have over
00:02:28
100,000 teachers. That's a significant
00:02:31
percentage of teachers in the United
00:02:33
States who have done exactly that. And
00:02:36
what we're finding first of all is a sea
00:02:38
change in policy from last year to this
00:02:40
year. So even just in the few months
00:02:42
that have passed since last academic
00:02:44
year to this academic year, what we're
00:02:47
finding is that schools across this
00:02:48
country are getting more strict with
00:02:50
their cell phones. They're more likely,
00:02:52
for example, to have a bell-to-bell
00:02:54
policy, meaning that students at that
00:02:56
school are not allowed to use their
00:02:57
phone from the first bell to the last
00:03:00
bell. And we're seeing most of that
00:03:02
change happen in, for example, the
00:03:04
middle and high schools because
00:03:06
elementary schools typically have
00:03:07
stricter policies, so they were already
00:03:09
strict. But we're seeing American high
00:03:11
schools, for example, shift to this new
00:03:13
stricter policy. Second thing that we're
00:03:16
finding is that the stricter the policy,
00:03:19
the happier the teacher. So these
00:03:21
teachers, 100,000 teachers, are saying
00:03:24
overwhelmingly that they prefer to teach
00:03:26
in school. They're They're more
00:03:27
satisfied teaching in schools that have
00:03:30
stricter policies. And finally, when we
00:03:33
ask these teachers, "What percentage of
00:03:34
kids, from 0% to 100%, would you guess
00:03:39
are on their phones for non-academic
00:03:41
reasons during class?" And we we find
00:03:44
that the same pattern is that, you know,
00:03:46
in the stricter schools, you know, kids
00:03:49
are of course less likely to be on their
00:03:50
phones. And here's one thing I want to
00:03:52
emphasize. It's not just when kids are
00:03:54
allowed to be on their phones, it's
00:03:55
where schools let those students keep
00:03:59
their phones. You can be a bell-to-bell
00:04:01
school and say, "You know what? In our
00:04:03
school you can't use your phone all day,
00:04:05
but you can keep it anywhere you want."
00:04:08
And we're finding that that matters.
00:04:10
When kids have their phone in their hand
00:04:12
or in their back pocket or even in their
00:04:14
backpack, they're more tempted, it
00:04:16
seems, to look at their phones than if
00:04:18
it's in their hallway locker, it's in a,
00:04:20
you know, centralized place,
00:04:23
etc.
00:04:25
Well, and one of the other things that
00:04:27
you noted in the most recent
00:04:29
tranche of research is that not only do
00:04:31
you have to focus on the potential use
00:04:34
of cell phones, but it's also the
00:04:36
laptops as well because seemingly so
00:04:38
many students are doing the majority of
00:04:41
their work for school on their laptop. I
00:04:43
know my kids are. Right.
00:04:45
>> And who doesn't?
00:04:46
Right, exactly. And obviously there has
00:04:48
to be a temptation there while you're
00:04:50
doing your work on the laptop like,
00:04:52
well, I can slide my social media onto a
00:04:55
different screen and have both at the
00:04:57
same time. Right. One tab for, you know,
00:05:00
doing my calculus and another tab for
00:05:02
like looking up love story. And you
00:05:04
know,
00:05:05
you know, you know, it's it's um the
00:05:07
co-location of academic work and
00:05:10
temptation on the same exact device, you
00:05:13
know, literally within pixels of each
00:05:15
other, within a swipe of each other,
00:05:16
within a click of each other. You know,
00:05:18
the analogy I would give you is it's
00:05:20
like asking kids salad in the middle of
00:05:22
a bakery, right? You can do it. But you
00:05:26
know, there are a lot of other things
00:05:27
that you would prefer. And I feel the
00:05:29
same way about myself. I mean, with no
00:05:31
disrespect to my colleagues because as
00:05:34
you know, I love this university with
00:05:36
all my heart and soul. But I have to go
00:05:38
to boring meetings, right? Who doesn't?
00:05:40
And if I have my laptop, the temptation
00:05:43
to stop taking notes on the meeting and
00:05:45
to just go peek at my inbox, right?
00:05:49
You know, look up that thing that I was
00:05:51
looking up 5 minutes before the meeting.
00:05:53
It is so strong. And therefore, we are
00:05:55
finding in our data,
00:05:57
you know, the same pattern with kids. I
00:05:58
mean, I don't know if it's therefore,
00:05:59
but I'll just say that we added a
00:06:01
question this school year. I told you
00:06:03
that the survey started last year. We're
00:06:05
um extending it. We added a question,
00:06:08
which is what percentage of students do
00:06:09
you suspect are doing personal things
00:06:13
like texting or social media from their
00:06:15
laptop in class? And a striking one in
00:06:18
three students, according to American
00:06:20
school teachers, are currently using
00:06:22
their laptops for non-academic purposes
00:06:25
during the school day. And as a
00:06:27
professor, again, I love my students.
00:06:30
Literally love them.
00:06:31
But if I [clears throat]
00:06:33
their laptops in my class, I think the
00:06:35
percentage would be similar, you know,
00:06:37
if not higher. Yeah.
00:06:39
Um you talked a moment ago about the
00:06:42
component of mental health that
00:06:45
seemingly becomes very important. And I
00:06:48
think it's a discussion where a lot of
00:06:50
people are having it, but maybe it
00:06:52
hasn't been fully followed through as to
00:06:54
just how these devices are impacting the
00:06:57
mental health, especially of our
00:06:59
children whose, in many cases, when
00:07:01
you're in middle school or high school,
00:07:02
your brain and your body are still
00:07:04
developing at that point.
00:07:06
You know, this generation, so, you know,
00:07:08
we all went through childhood and
00:07:10
adolescence. And you know, many of us
00:07:11
will remember that that was not the
00:07:13
easiest period of our lives. We were
00:07:15
developing a sense of of self-concept,
00:07:18
self-esteem, what's my niche, what's my
00:07:20
role, what's my status, am I liked, do I
00:07:23
belong here?
00:07:25
friends. So we've all been through that
00:07:28
period. And we might recall that it was
00:07:31
a fraught period. I mean, it's not at
00:07:32
all easy.
00:07:34
And one of the things that really
00:07:36
worries me as a psychologist who has
00:07:38
worked with adolescents for
00:07:40
her career is that now we have this
00:07:42
device that enables you to not look at
00:07:45
another person in the eye, to not have
00:07:48
conversation, to not get to know
00:07:50
someone. I mean, who enjoys those
00:07:52
awkward first opening conversations with
00:07:55
another human? Maybe complete
00:07:57
extroverts. But for a lot of us, there
00:07:59
is a little awkwardness. And what
00:08:01
research is showing, you know, separate
00:08:03
from the study that I just described, is
00:08:05
that face-to-face in-person interaction,
00:08:07
particularly among young people, is on a
00:08:09
steep decline. I think that is very
00:08:12
relevant
00:08:12
to another worrisome trend, which is we
00:08:15
are really seeing a crisis in mental
00:08:17
health in young people. I'll speak about
00:08:20
Gen Z adults because that's the most
00:08:22
documented.
00:08:24
As you know,
00:08:25
are, you know, really in the same
00:08:26
generation. I mean, this is in some ways
00:08:29
the least happy generation that we have
00:08:31
documented in human history. And if you
00:08:33
ask the question, "Why?" Like what would
00:08:36
There are, I'm sure, multiple reasons.
00:08:38
Political polarization doesn't help.
00:08:40
There's climate change and so forth. But
00:08:43
I have to believe that the astronomic
00:08:45
increase in the use of phones and social
00:08:48
media have at least contributed to a
00:08:51
crisis of well-being in our young
00:08:53
people.
00:08:55
How then does it also, and we're talking
00:08:57
about this in the scope of the students
00:08:58
and the teachers, but to a degree, and
00:09:00
you kind of alluded to it that this is a
00:09:01
much larger conversation outside of the
00:09:04
schools,
00:09:05
do the parents need to have and play an
00:09:07
important role in this process as well?
00:09:10
You know, there is hope. And I know, you
00:09:12
know, painting this picture of
00:09:14
technology and its, you know, inevitable
00:09:16
march forward, right? The co-location of
00:09:19
temptation and virtue in the same
00:09:21
device. I mean, it does make you want to
00:09:23
like throw up your hands and say like,
00:09:24
well, I'm helpless to to change things.
00:09:28
But I do think there's hope. And the
00:09:29
reason why is that we are influenced by
00:09:32
our surroundings. And we are most
00:09:34
influenced by our immediate
00:09:35
surroundings. So yes, there are macro
00:09:38
cultural trends that you're not going to
00:09:40
have a lot of control over. But you do
00:09:43
have control over your local
00:09:45
environment. So think locally. For
00:09:47
example, if you are a parent, you can
00:09:50
choose which school to send your child
00:09:53
to because that school will have a
00:09:55
culture. And that school's culture is
00:09:57
going to influence your child's
00:09:59
development much more than American
00:10:01
culture at large. Same thing for the
00:10:03
home. When we raised our two daughters,
00:10:05
my husband Jason and I would often get,
00:10:08
as so many parents do, "Well, my
00:10:10
friend's family does it this way. They
00:10:12
watch TV all day. Like, they have junk
00:10:15
food. Like, why can't we have Oreos?"
00:10:17
And we said to our daughters, "Because
00:10:18
you're a Duckworth, and in the Duckworth
00:10:20
family, we do things the Duckworth
00:10:21
family way." So, I think every leader
00:10:24
understands this. Every parent at some
00:10:26
level has an intuition, but I just want
00:10:28
to empower those of us who don't like
00:10:31
the cultural trends and say, "You know
00:10:33
what? I'm going to think locally, and
00:10:34
I'm going to act locally." What's the
00:10:36
next step then in the research that
00:10:38
you're doing? Obviously, you said that
00:10:40
the study is still up and running, and
00:10:42
teachers can take part of it.
00:10:43
phonesinfocus.org.
00:10:45
What's next?
00:10:46
So, we are collecting data through the
00:10:48
end of this academic year. So, just for
00:10:49
a couple more months, teachers have an
00:10:51
opportunity to share their perspective.
00:10:53
What we're going to do with all of that
00:10:55
data is match it. And then, we're
00:10:57
working actually with the National
00:10:58
Governors Association, and the majority
00:11:00
the vast majority of states are formal
00:11:02
partners in this. So, of the our 50
00:11:05
states um in the United States, and what
00:11:07
we're going to do through these
00:11:08
partnerships is match our survey data to
00:11:12
records on attendance, to records on
00:11:14
standardized achievement test scores. We
00:11:17
also are going to actually look at
00:11:18
survey measures of students' well-being
00:11:21
and engagement in class. We're going to
00:11:23
take all this data and ask the question,
00:11:25
"Which policies in the United States for
00:11:27
cell phones in schools are the best
00:11:30
policies with the best uh long-term
00:11:32
student outcomes?"
00:11:34
Angela, always great to talk to you
00:11:35
about this cuz it's so important.
00:11:37
Appreciate it, and look forward to
00:11:38
talking to you again down the road.
00:11:40
Awesome, awesome. I love this place.
00:11:42
Wharton really cares about impact, and
00:11:43
I'm very, very um
00:11:45
privileged, I should say, and grateful
00:11:47
to be part of this great university and
00:11:49
doing some of this important work.
