An Easy Way To Help Kids Learn At Home: Turn On The Captions
Making captions the default setting for kids' TV could be an easy way to boost literacy
Natalie Wexler
A new organization is pushing for children’s TV and video programs to
automatically display captions to boost literacy. It’s an easy thing to
do, and it has even more research behind it than advocates realize.
“If I told you there was a magic button,” says a British-accented
child’s voice-over in a video, “and when it’s pressed, it doubles my
chances of becoming literate—which decreases the chances of me
committing a crime, and even reduces the chances of me dying early by
75%—would you believe me?”
The big reveal in the video—produced by a U.K.-based advocacy group
called Turn on the Subtitles, or TOTS—is that the button isn’t magic at
all. It’s real, and it turns on the captions that already exist for
almost every TV or video-on-demand program, including those on YouTube.
TOTS’ goal is to raise awareness among parents to turn on those
captions at home—or, better yet, to have broadcasters and content
providers display the captions automatically on programs directed at
six- to ten-year-olds. Viewers would be able to turn the captions off,
but the default setting would be “on.”
Today In: Education
The idea that this simple change would boost kids’ reading ability has
solid evidence behind it, although the claims made by the adorable
voice in the video may overstate the benefits. TOTS relies on research
showing that children generally do read captions when they’re
available, and that they lead to significantly better outcomes,
especially among those who struggle with reading. One experiment in
India involved schoolchildren who couldn’t read a single letter in
Hindi. They were shown videos of Hindi songs once a week, with or
without captions in the same language. After five years, 70% of the
kids in the group that got captions were functional readers, compared
to only 34% in the group that didn’t.
It’s tempting to conclude that while children are stuck at home during
the current pandemic, often glued to TV screens, we could keep their
reading progress on track just by turning on captions. But there’s no
evidence that captions alone will have this effect, as opposed to
captions shown to children who also attend school regularly, in person.
And captions alone won’t be much help to children who haven’t yet
learned to decode, or sound out, words. A few kids will be able to pick
up the skill of decoding more or less on their own, but most will need
explicit instruction, preferably with systematic phonics.
Still, even if it’s not a panacea, turning on captions could be a
simple and painless way to improve reading ability for many children.
And the evidence behind the idea goes beyond the studies of captions
(or same-language subtitles) cited by TOTS. Captions promote what
reading researchers call “fluency”—the ability to read smoothly and
with appropriate expression. Often overlooked or misunderstood, fluency
provides what one expert has called the “bridge” between decoding and
comprehension. And the lack of it, or disfluency, holds many students
back, especially when they reach higher grade levels.
One prerequisite for fluency is the ability to decode automatically.
That frees up space in the mind to focus on meaning. The other
component is “prosody,” or the ability to do things like pause when
appropriate—for example, at a comma or a period—or put emphasis on the
right words.
When schools have focused on fluency, they’ve often mistaken the goal
as speed. Kids are told to just reread a passage until they can do it
as quickly as possible. It’s true that if you read too slowly, it
interferes with comprehension. But that also happens if you read too
quickly. The point should be to read for meaning, not speed.
One way for students to develop fluency is to listen to an expert
reader while following along in the text themselves—an experience quite
similar to watching a video with captions. Kids can hear how words are
pronounced, while matching them to their written forms, and hear all
the aspects of expression that go into prosody.
But most research on fluency has focused on having children read a text
repeatedly themselves, perhaps after hearing it modeled by an expert.
Not only do they get better at reading that specific text, they become
better at understanding other texts as well. Kids who watch a captioned
video won’t get a chance to engage in repeated rereading, unless it’s a
recording and they watch it again and again (which, as many parents can
attest, children often want to do).
Still, there’s also evidence that listening to an expert reader can
have a powerful effect on comprehension even without repeated
rereading—and that the effects also transfer. In one small study done
in England, for example, struggling readers who simply listened to a
teacher read two novels aloud over a period of three months made a
whopping sixteen months of progress in comprehension, as measured by a
standardized test.
One caveat is that watching a captioned video that consists mostly of
dialogue won’t help familiarize kids with the conventions of written
language, which is almost always more complex than spoken language. But
there are lots of videos out there showing adults reading children’s
books aloud, especially during the current period of remote
learning—including some featuring famous actors that already
automatically display captions. Tennessee’s education department is
broadcasting lessons on public television as well as posting them on
YouTube, and the English language arts videos consist mostly of
read-alouds. Turning on those captions could be hugely beneficial. (To
turn on captions on YouTube videos, just click the button marked “CC”
at the bottom right. Alas, the captions on the Tennessee videos are
auto-generated and, while accurate, lack appropriate punctuation.)
To be sure, captioned TV or videos aren’t a substitute for a rich,
interactive, in-person education. And other crucial factors go into
comprehension in addition to fluency—perhaps most important, and most
overlooked, knowledge of the topic at hand. But especially as compared
to other literacy-related initiatives, it takes little effort to turn
captions on. They can reach any child who has a TV, as over 95% of
American households do. That means they can reach children in
households too poor to have reliable internet access, which are the
same households that are more likely to have struggling readers.
There’s no downside, and the potential benefits are substantial.
And when schooling eventually returns to normal, there’s much more that
can be done to boost fluency. Instead of turning fluency practice into
a mindless race against the clock, teachers can have kids read
repeatedly for meaning, engage in choral reading, learn songs, recite
poetry, and perform plays. Those activities may sound fusty and
old-fashioned, but research suggests they can help put many kids on the
path to academic success.
