Can technology help teach literacy in poor communities?

Breazeal is joined on the paper by Maryanne Wolf and Stephanie Gottwald, who are, respectively, the director and assistant director of the Center for Reading and Language Research at Tufts; Tinsley Galyean, a research affiliate at the MIT Media Lab and executive director of Curious Learning, a nonprofit organization the researchers created to develop and deploy their system; and Robin Morris, a professor of psychology at Georgia State University.


The concentration on early literacy reflects Wolf’s theory, popularized in her book “Proust and the Squid,” that the capacity to read, unlike the capacity to process spoken language, is not hard-coded into our genes. Consequently, early training is essential to establishing the neurological machinery on which the very capacity for literacy depends.

The researchers’ system consists of an inexpensive tablet computer using Google’s Android operating system.

Wolf and Gottwald combed through the literacy and early-childhood apps available for Android devices to identify several hundred that met their quality criteria and addressed a broad enough range of skills to lay a foundation for early reading education. The researchers also developed their own interface for the tablets, which grants users access only to approved educational apps. Across the three deployments, the tablets were issued to children ranging in age from 4 to 11.

“When we do these deployments, we purposely don’t tell the kids how to use the tablets or instruct them about any of the content,” Breazeal says. “Our argument is, if you’re going to be able to scale this to reach 100 million kids, you can’t bring people in to coach kids what to do. You just make the tablets available, and they need to figure everything out from then on out. And what we find is, the kids do it. When we first did Ethiopia, we had all these protocols and subprotocols. What if it’s a week and they haven’t turned them on? What if it’s three weeks and they haven’t turned them on? Within minutes, the kids turn them on. By the end of the day, they’ve literally explored every app on the tablet.”


The Ethiopian trial, which the researchers conducted in collaboration with the One Laptop per Child program, involved children aged 4 to 11 who had no prior exposure to spoken English or any written language. After a year using the tablets, children were tested on their understanding of roughly 20 spoken English words, taken at random from apps loaded on the tablets. More than half of the students knew at least half the words, and all the students knew at least four.

When presented with strings of Roman letters in a random order, 90 percent could identify at least 10 of them, and all the children could supply the sounds corresponding to at least two of them. Perhaps most important, 35 percent of the children could recognize at least one English word by sight. These figures roughly accord with those of children entering kindergarten in the U.S.

In the South African trial, rising second graders who had been issued tablets the year before were able to sound out four times as many words as those who hadn’t, and in the U.S. trial, which involved only 4-year-olds and lasted only four months, half-day preschool students were able to supply the sounds corresponding to nearly six times as many letters as they had been before the trial.

Since the trials reported in the new paper, Curious Learning has launched new trials in Uganda, Bangladesh, India, and the U.S. In all, 2,000 children have had the opportunity to use the tablets.

Currently, the team is concentrating on analyzing data collected from the trials. Which apps do the children spend most time with? Which apps’ use correlates best with literacy outcomes? Curious Learning is also looking for partners to help launch larger pilot programs, with 5,000 to 10,000 children.

“There’s a core scientific question, which is understanding what the nature of this child-driven, curiosity-driven learning looks like,” Breazeal says. “We need to understand how they learn, which is a fundamentally social process, where they explore the tablet together, they discover things through that exploration, and then they talk-talk-talk-talk, and they share those ideas. So it’s a profoundly social, peer-to-peer-based learning process. We have to have create a technology and an experience that supports that process.”
