00:00:00
The topic of smartphones in schools has
00:00:03
become an important one in the last
00:00:05
couple of years. School districts are
00:00:07
trying to set proper policy that has a
00:00:10
positive impact on students and their
00:00:12
learning. The problem is that many in
00:00:14
education feel that cell phones hinder
00:00:17
that process. Pleasure to be joined
00:00:19
right now by Angela Duckworth who's a
00:00:21
professor of operations, information,
00:00:22
and decisions here at the Wharton
00:00:24
School. She is part of new research
00:00:26
coming out about this topic specifically
00:00:29
and what we're seeing in our schools at
00:00:31
the moment. Angela, great to talk to you
00:00:33
again. How are you?
00:00:34
>> Thank you for having me. I'm good.
00:00:36
>> It's interesting you and I were talking
00:00:38
about this before we started this
00:00:39
interview. This has obviously become a
00:00:41
very important topic in and around the
00:00:44
school right now. I think not only is
00:00:46
school cell phone policy an urgent
00:00:48
topic, it may be one of the last
00:00:50
bipartisan topics there is in the
00:00:54
universe. So whether you are red or
00:00:57
blue, whether you are pro- teacher union
00:00:59
or pro-charter school, like we have not
00:01:02
found the educator who doesn't care
00:01:04
about this issue and who doesn't feel
00:01:06
like we should be doing more than we're
00:01:08
doing right now,
00:01:09
>> right? And and so obviously the the the
00:01:11
component of learning is a big one here,
00:01:13
but as you just alluded to, there's an
00:01:15
element of this is is how the teachers
00:01:17
are dealing with this and being able to
00:01:20
try and work through their normal
00:01:22
process during a day.
00:01:24
>> You know, the policy the default policy
00:01:26
for um you know, several years just I'm
00:01:29
talking about nationwide, right? Just
00:01:31
sort of like what are K12 schools doing
00:01:33
about phones? Um, in America, you know,
00:01:36
for a long time, the default is that
00:01:38
every teacher reigns supreme over their
00:01:41
classroom and that includes phones. So,
00:01:44
if you are a teacher who says, "I don't
00:01:47
care." And you can have your phones on
00:01:49
your person, great, that's your
00:01:50
classroom. But then when the students go
00:01:52
to the next period, they might have a
00:01:54
teacher who does care and then you have
00:01:56
to put your phones in a cubby and and so
00:01:58
forth. And that is actually how much of
00:01:59
American education works, right? uh but
00:02:02
in the case of phones I think what we
00:02:04
have is what some scientists call
00:02:06
collective action trap um that is where
00:02:09
individual decision-m individual
00:02:11
willpower is no match for the problem
00:02:15
and I think what teachers have been
00:02:17
saying in our survey data which I know
00:02:19
we're here to talk about is that they
00:02:21
need help just legislate cell phone
00:02:25
policy as a teacher on their own
00:02:28
separate from what the school is doing
00:02:30
as a
00:02:31
Okay. So, let's dig into the research
00:02:33
because this is part of a larger
00:02:35
research project that you're on is
00:02:37
ongoing right now. This first part was a
00:02:39
survey about some of these policies.
00:02:42
>> So, there is a national survey that is
00:02:44
up and running right now. We we we're
00:02:47
like a convenience store, you know, 247.
00:02:49
We never close. And it lives at
00:02:52
www.phonesinfocus.org.
00:02:56
and any school teacher in the United
00:02:58
States, we're looking for public school
00:03:00
teachers, K12, can can log on and in a
00:03:03
confidential way share in a matter of
00:03:06
minutes what the policy is at their
00:03:08
school and from their perspective, you
00:03:11
know, how's it going. We're really
00:03:13
interested in looking for changes in
00:03:16
policy that predict changes in outcome.
00:03:19
So on the same survey, you're also asked
00:03:22
you whether your policy at your school
00:03:24
has changed in recent years, and if so,
00:03:27
how. And what we're seeing in the 20,000
00:03:30
plus responses that we've already
00:03:32
received from public school educators
00:03:34
across all 50 states is an important
00:03:37
pattern, which is that the stricter the
00:03:40
policy, the happier the teacher. And
00:03:44
again, in this cross-sectional snapshot,
00:03:46
the stricter the policy, the less
00:03:49
distraction there is for students uh in
00:03:51
in terms of their academic work.
00:03:54
>> One of the things you brought up to me
00:03:55
beforehand, and it's an interesting
00:03:56
component of it when you're thinking
00:03:58
about these rules, the proximity of
00:04:01
where a student can hold their phone is
00:04:04
also a factor in this as well. You know,
00:04:06
one way to appreciate the importance of
00:04:08
physical distance on psychological
00:04:11
distance and there really is a a kind of
00:04:14
a law in psychology that you know more
00:04:16
physical distance creates more
00:04:18
psychological distance from from
00:04:20
temptation. One way we can appreciate
00:04:21
this is to consider our own relationship
00:04:24
with our phone. I don't know any adults
00:04:26
who have a completely unconlicted, you
00:04:29
know, um I' I've got this um
00:04:31
relationship with their own phones. This
00:04:33
is not a teenager problem. I think it's
00:04:35
not just a kid problem. And if I have my
00:04:37
phone, you know, one ft away, one foot
00:04:40
away, like that's a different level of
00:04:42
temptation than if I, for example, have
00:04:44
my phone in another room or if you
00:04:47
really want to get me off my phone. If
00:04:49
you put my phone upstairs and I have to
00:04:51
walk up eight stairs to get it, of
00:04:54
course, it's trivial, right? Like, well,
00:04:56
how hard could that be?
00:04:57
>> But but yeah, that makes a huge
00:04:58
difference. And that may be why we're
00:05:00
finding that schools, for example, who
00:05:04
require their students to keep their
00:05:05
phones in their hallway lockers, which
00:05:07
are not, you know, 1 ft away from them
00:05:09
when they're in class. They're typically
00:05:11
more than 30 feet away from them. And in
00:05:12
fact, they can be on a different floor.
00:05:14
You know, those schools perform
00:05:15
extremely well in the outcome data that
00:05:18
we are collecting. And one of the other
00:05:20
components of the policy angle on this
00:05:23
is uh not just how from potential
00:05:27
classroom to classroom that different
00:05:29
teachers have different thoughts about
00:05:31
cell phone policy but within the school
00:05:33
structure itself K through 12 that you
00:05:36
may come up with one policy in grade
00:05:38
school, one policy in middle school and
00:05:40
another one in high school.
00:05:42
>> We find a pattern again across the
00:05:43
United States that actually I I can't
00:05:46
speak for the whole team. It surprised
00:05:48
me. So when you think about cell phones,
00:05:50
you typically think about teenagers and
00:05:52
you think about social media again, you
00:05:53
think about teenagers. And when you
00:05:55
worry, you worry about teenagers. But
00:05:58
we're finding that the schools that
00:05:59
serve teenagers, which are the high
00:06:01
schools, right? That's grade 9 through
00:06:02
12, 14 to 18 years old, those schools
00:06:06
paradoxically have the the least strict
00:06:10
rules. So perhaps arguably just when
00:06:13
students need the most support in
00:06:16
regulating their attention, their
00:06:18
impulses to stay focused on academic
00:06:21
work, which in prior research shows
00:06:24
teenagers recognize that academic work
00:06:26
is good for their long-term future. This
00:06:28
is true across the board across socio
00:06:31
economic status. A students, F students,
00:06:34
everybody knows that school is good for
00:06:36
them. And so it is in the teen years
00:06:38
perhaps when students need the most
00:06:40
support and when temptations are
00:06:42
strongest that we give them the least
00:06:44
support in terms of school cell phone
00:06:45
policies. Only one in four schools in
00:06:48
our sample at the high school level has
00:06:51
a bellto bell policy meaning you can't
00:06:53
use it from the first bell of school to
00:06:54
the you know last bell of school. So all
00:06:56
day all away that's only one in four
00:06:59
high schools. But when you look at the
00:07:00
younger grades it's flipped. So when you
00:07:02
look K8, that's more like three out of
00:07:05
four schools in our sample.
00:07:07
>> But still the component of mental health
00:07:10
is part of this discussion as well
00:07:12
because this is going back to just
00:07:14
screen time in general with our kids.
00:07:17
>> Yeah. The the the fact that I want to,
00:07:19
you know, begin with and is just to say
00:07:21
it is a fact that there is a mental
00:07:22
health crisis among youth. Sometimes I'm
00:07:25
asked like is it just an artifact of the
00:07:28
data? You know, is there something in
00:07:29
report? I'm like no. kids today really
00:07:32
are struggling. They're struggling with
00:07:34
anxiety. They're struggling with
00:07:35
loneliness. Uh and they're studying
00:07:38
they're struggling with the the symptoms
00:07:40
of depression relative to other
00:07:42
generations of kids, you know, in in
00:07:44
years past. So, so the connection
00:07:46
between teen mental health and screens
00:07:50
is a big topic that we're not going to
00:07:52
have uh time to discuss entirely today,
00:07:54
but I will tell you this now that we
00:07:56
have thousands and thousands of
00:07:58
educators and hopefully um hopefully and
00:08:00
by the way, if you're listening to this
00:08:01
and you know anybody who's a school
00:08:03
teacher, please send them to our phones
00:08:06
and focus.org survey. But now that we
00:08:08
have some responses, we can find these
00:08:11
schools and talk to them. And I will
00:08:13
tell you what the principles and the
00:08:14
teachers are telling us. They say that
00:08:17
yeah, test scores, you know, are
00:08:19
influenced by by uh cell phone policies.
00:08:21
So are the number of books checked out
00:08:23
of the library going up in schools that
00:08:26
have uh lower or I should say more
00:08:29
restrictive policies, but social
00:08:31
emotional outcomes, how are kids feeling
00:08:33
and how are they relating to each other?
00:08:36
Um that's the primary outcome for many
00:08:38
of the educators that I'm speaking with.
00:08:39
They say when we started a policy that
00:08:42
really restricted phone use during
00:08:44
school hours and that includes where
00:08:45
kids keep it, they made eye contact with
00:08:47
each other more. They talked to each
00:08:49
other more. You actually hear noise in
00:08:51
the cafeteria. The noise the den of
00:08:54
young people interact with each other.
00:08:56
Before it was like you could you could
00:08:58
hear a pin drop because the kids would
00:08:59
just be silently, you know, scrolling
00:09:02
through something with their thumb and
00:09:04
shoveling food into their mouths. So, so
00:09:06
I I really, you know, I don't want to
00:09:07
sound like a lite because I think the
00:09:09
role of technology is complicated and
00:09:11
it's certainly got a lot of affordances
00:09:13
that we don't want to ignore, but I
00:09:15
worry about young people not interacting
00:09:17
with each other, not having realistic,
00:09:21
sensible ideas about, you know, what is
00:09:24
expected of them and I worry about their
00:09:26
attention.
00:09:28
>> So, as you're collecting this data right
00:09:30
now, what are the next steps in the
00:09:32
process for this research? Well, you
00:09:35
know, there are tens of thousands of uh
00:09:37
middle schools and high schools in
00:09:38
particular. As I mentioned before, a lot
00:09:41
of the action is at the higher grade
00:09:42
levels because that's where the policies
00:09:44
are the least restrictive. And as a
00:09:46
developmental psychologist, I will tell
00:09:47
you that these are our most impulsive
00:09:49
years of life. So, so we are thinking
00:09:53
that maybe just maybe every middle and
00:09:57
high school in America might participate
00:09:59
in our survey. That would be at least
00:10:02
one educator from every middle school
00:10:04
and high school in the United States
00:10:06
going at some point this month, this
00:10:09
week, maybe today to phones
00:10:11
andfocus.org.
00:10:13
And if we really do that, if we
00:10:16
accomplish that goal, then we will have
00:10:17
a census of what is going on in this
00:10:20
country. We're going to match that to
00:10:22
standardized test scores, to attendance
00:10:24
data, also to measures of climate and
00:10:27
student engagement and well-being. And
00:10:29
then we are going to deliver the results
00:10:31
to the educators who answered the survey
00:10:34
and you know to legislators who are
00:10:35
making important decisions about the
00:10:38
specifics of cell phone policy and how
00:10:40
to optimize youth well-being, youth
00:10:43
engagement and yes, youth achievement as
00:10:45
well.
00:10:46
>> Angela, great to talk to you again.
00:10:47
Thanks very much.
00:10:49
>> Always good to see you.
00:10:50
>> Thank you. Angela Duckworth, professor
00:10:51
of operations information and decisions
00:10:53
here at the Warren School and again that
00:10:55
