How a Radical New Teaching Method Could Unleash a Generation of Geniuses

In 1999, Sugata Mitra was chief scientist at a company in New Delhi that trains software developers. His office was on the edge of a slum, and on a hunch one day, he decided to put a computer into a nook in a wall separating his building from the slum. He was curious to see what the kids would do, particularly if he said nothing. He simply powered the computer on and watched from a distance. To his surprise, the children quickly figured out how to use the machine.

Over the years, Mitra got more ambitious. For a study published in 2010, he loaded a computer with molecular biology materials and set it up in Kalikuppam, a village in southern India. He selected a small group of 10- to 14-year-olds and told them there was some interesting stuff on the computer, and might they take a look? Then he applied his new pedagogical method: He said no more and left.

Over the next 75 days, the children worked out how to use the computer and began to learn. When Mitra returned, he administered a written test on molecular biology. The kids answered about one in four questions correctly. After another 75 days, with the encouragement of a friendly local, they were getting every other question right. “If you put a computer in front of children and remove all other adult restrictions, they will self-organize around it,” Mitra says, “like bees around a flower.”

A charismatic and convincing proselytizer, Mitra has become a darling in the tech world. In early 2013 he won a $1 million grant from TED, the global ideas conference, to pursue his work. He’s now in the process of establishing seven “schools in the cloud,” five in India and two in the UK. In India, most of his schools are single-room buildings. There will be no teachers, curriculum, or separation into age groups—just six or so computers and a woman to look after the kids’ safety. His defining principle: “The children are completely in charge.”

“The bottom line is, if you’re not the one controlling your learning, you’re not going to learn as well.”

Mitra argues that the information revolution has enabled a style of learning that wasn’t possible before. The exterior of his schools will be mostly glass, so outsiders can peer in. Inside, students will gather in groups around computers and research topics that interest them. He has also recruited a group of retired British teachers who will appear occasionally on large wall screens via Skype, encouraging students to investigate their ideas—a process Mitra believes best fosters learning. He calls them the Granny Cloud. “They’ll be life-size, on two walls” Mitra says. “And the children can always turn them off.”

Mitra’s work has roots in educational practices dating back to Socrates. Theorists from Johann Heinrich Pestalozzi to Jean Piaget and Maria Montessori have argued that students should learn by playing and following their curiosity. Einstein spent a year at a Pestalozzi-inspired school in the mid-1890s, and he later credited it with giving him the freedom to begin his first thought experiments on the theory of relativity. Google founders Larry Page and Sergey Brin similarly claim that their Montessori schooling imbued them with a spirit of independence and creativity.

In recent years, researchers have begun backing up those theories with evidence. In a 2011 study, scientists at the University of Illinois at Urbana-Champaign and the University of Iowa scanned the brain activity of 16 people sitting in front of a computer screen. The screen was blurred out except for a small, movable square through which subjects could glimpse objects laid out on a grid. Half the time, the subjects controlled the square window, allowing them to determine the pace at which they examined the objects; the rest of the time, they watched a replay of someone else moving the window. The study found that when the subjects controlled their own observations, they exhibited more coordination between the hippocampus and other parts of the brain involved in learning and posted a 23 percent improvement in their ability to remember objects. “The bottom line is, if you’re not the one who’s controlling your learning, you’re not going to learn as well,” says lead researcher Joel Voss, now a neuroscientist at Northwestern University.

In 2009, scientists from the University of Louisville and MIT’s Department of Brain and Cognitive Sciences conducted a study of 48 children between the ages of 3 and 6. The kids were presented with a toy that could squeak, play notes, and reflect images, among other things. For one set of children, a researcher demonstrated a single attribute and then let them play with the toy. Another set of students was given no information about the toy. This group played longer and discovered an average of six attributes of the toy; the group that was told what to do discovered only about four. A similar study at UC Berkeley demonstrated that kids given no instruction were much more likely to come up with novel solutions to a problem. “The science is brand-new, but it’s not as if people didn’t have this intuition before,” says coauthor Alison Gopnik, a professor of psychology at UC Berkeley.

Gopnik’s research is informed in part by advances in artificial intelligence. If you program a robot’s every movement, she says, it can’t adapt to anything unexpected. But when scientists build machines that are programmed to try a variety of motions and learn from mistakes, the robots become far more adaptable and skilled. The same principle applies to children, she says.

Evolutionary psychologists have also begun exploring this way of thinking. Peter Gray, a research professor at Boston College who studies children’s natural ways of learning, argues that human cognitive machinery is fundamentally incompatible with conventional schooling. Gray points out that young children, motivated by curiosity and playfulness, teach themselves a tremendous amount about the world. And yet when they reach school age, we supplant that innate drive to learn with an imposed curriculum. “We’re teaching the child that his questions don’t matter, that what matters are the questions of the curriculum. That’s just not the way natural selection designed us to learn. It designed us to solve problems and figure things out that are part of our real lives.”

Some school systems have begun to adapt to this new philosophy—with outsize results. In the 1990s, Finland pared the country’s elementary math curriculum from about 25 pages to four, reduced the school day by an hour, and focused on independence and active learning. By 2003, Finnish students had climbed from the lower rungs of international performance rankings to first place among developed nations.

Nicholas Negroponte, cofounder of the MIT Media Lab, is taking this approach even further with his One Laptop per Child initiative. Last year the organization delivered 40 tablets to children in two remote villages in Ethiopia. Negroponte’s team didn’t explain how the devices work or even open the boxes. Nonetheless, the children soon learned to play back the alphabet song and taught themselves to write letters. They also figured out how to use the tablet’s camera. This was impressive because the organization had disabled camera usage. “They hacked Android,” Negroponte says.

One day Juárez Correa went to his whiteboard and wrote “1 = 1.00.” Normally, at this point, he would start explaining the concept of fractions and decimals. Instead he just wrote “½ = ?” and “¼ = ?”

“Think about that for a second,” he said, and walked out of the room.

While the kids murmured, Juárez Correa went to the school cafeteria, where children could buy breakfast and lunch for small change. He borrowed about 10 pesos in coins, worth about 75 cents, and walked back to his classroom, where he distributed a peso’s worth of coins to each table. He noticed that Paloma had already written .50 and .25 on a piece of paper.

“One peso is one peso,” he said. “What’s one-half?”

Juárez Correa felt a chill. He had never encountered a student with Paloma’s level of innate ability.

At first a number of kids divided the coins into clearly unequal piles. It sparked a debate among the students about what one-half meant. Juárez Correa’s training told him to intervene. But now he remembered Mitra’s research and resisted the urge. Instead, he watched as Alma Delia Juárez Flores explained to her tablemates that half means equal portions. She counted out 50 centavos. “So the answer is .50,” she said. The other kids nodded. It made sense.

For Juárez Correa it was simultaneously thrilling and a bit scary. In Finland, teachers underwent years of training to learn how to orchestrate this new style of learning; he was winging it. He began experimenting with different ways of posing open-ended questions on subjects ranging from the volume of cubes to multiplying fractions. “The volume of a square-based prism is the area of the base times the height. The volume of a square-based pyramid is that formula divided by three,” he said one morning. “Why do you think that is?”

He walked around the room, saying little. It was fascinating to watch the kids approach the answer. They were working in teams and had models of various shapes to look at and play with. The team led by Usiel Lemus Aquino, a short boy with an ever-present hopeful expression, hit on the idea of drawing the different shapes—prisms and pyramids. By layering the drawings on top of each other, they began to divine the answer. Juárez Correa let the kids talk freely. It was a noisy, slightly chaotic environment—exactly the opposite of the sort of factory-friendly discipline that teachers were expected to impose. But within 20 minutes, they had come up with the answer.

“Three pyramids fit in one prism,” Usiel observed, speaking for the group. “So the volume of a pyramid must be the volume of a prism divided by three.”

Juárez Correa was impressed. But he was even more intrigued by Paloma. During these experiments, he noticed that she almost always came up with the answer immediately. Sometimes she explained things to her tablemates, other times she kept the answer to herself. Nobody had told him that she had an unusual gift. Yet even when he gave the class difficult questions, she quickly jotted down the answers. To test her limits, he challenged the class with a problem he was sure would stump her. He told the story of Carl Friedrich Gauss, the famous German mathematician, who was born in 1777.

When Gauss was a schoolboy, one of his teachers asked the class to add up every number between 1 and 100. It was supposed to take an hour, but Gauss had the answer almost instantly.

“Does anyone know how he did this?” Juárez Correa asked.

A few students started trying to add up the numbers and soon realized it would take a long time. Paloma, working with her group, carefully wrote out a few sequences and looked at them for a moment. Then she raised her hand.

“The answer is 5,050,” she said. “There are 50 pairs of 101.”

Juárez Correa felt a chill. He’d never encountered a student with so much innate ability. He squatted next to her and asked why she hadn’t expressed much interest in math in the past, since she was clearly good at it.

“Because no one made it this interesting,” she said.

Our educational system is rooted in the industrial age. It values punctuality, attendance, and silence above all else.

Paloma’s father got sicker. He continued working, but he was running a fever and suffering headaches. Finally he was admitted to the hospital, where his condition deteriorated; on February 27, 2012, he died of lung cancer. On Paloma’s last visit before he passed away, she sat beside him and held his hand. “You are a smart girl,” he said. “Study and make me proud.”

Paloma missed four days of school for the funeral before returning to class. Her friends could tell she was distraught, but she buried her grief. She wanted to live up to her father’s last wish. And Juárez Correa’s new style of curating challenges for the kids was the perfect refuge for her. As he continued to relinquish control, Paloma took on more responsibility for her own education. He taught the kids about democracy by letting them elect leaders who would decide how to run the class and address discipline. The children elected five representatives, including Paloma and Usiel. When two boys got into a shoving match, the representatives admonished the boys, and the problem didn’t happen again.

Juárez Correa spent his nights watching education videos. He read polemics by the Mexican cartoonist Eduardo del Río (known as Rius), who argued that kids should be free to explore whatever they want. He was also still impressed by Mitra, who talks about letting children “wander aimlessly around ideas.” Juárez Correa began hosting regular debates in class, and he didn’t shy away from controversial topics. He asked the kids if they thought homosexuality and abortion should be permitted. He asked them to figure out what the Mexican government should do, if anything, about immigration to the US. Once he asked a question, he would stand back and let them engage one another.

A key component in Mitra’s theory was that children could learn by having access to the web, but that wasn’t easy for Juárez Correa’s students. The state paid for a technology instructor who visited each class once a week, but he didn’t have much technology to demonstrate. Instead, he had a batch of posters depicting keyboards, joysticks, and 3.5-inch floppy disks. He would hold the posters up and say things like, “This is a keyboard. You use it to type.”

As a result, Juárez Correa became a slow-motion conduit to the Internet. When the kids wanted to know why we see only one side of the moon, for example, he went home, Googled it, and brought back an explanation the next day. When they asked specific questions about eclipses and the equinox, he told them he’d figure it out and report back.

Juárez Correa also brought something else back from the Internet. It was the fable of a forlorn burro trapped at the bottom of a well. Since thieves had broken into the school and sliced the electrical cord off of the classroom projector (presumably to sell the copper inside), he couldn’t actually show them the clip that recounted the tale. Instead, he simply described it.

One day, a burro fell into a well, Juárez Correa began. It wasn’t hurt, but it couldn’t get out. The burro’s owner decided that the aged beast wasn’t worth saving, and since the well was dry, he would just bury both. He began to shovel clods of earth into the well. The burro cried out, but the man kept shoveling. Eventually, the burro fell silent. The man assumed the animal was dead, so he was amazed when, after a lot of shoveling, the burro leaped out of the well. It had shaken off each clump of dirt and stepped up the steadily rising mound until it was able to jump out.

Juárez Correa looked at his class. “We are like that burro,” he said. “Everything that is thrown at us is an opportunity to rise out of the well we are in.”

When the two-day national standardized exam took place in June 2012, Juárez Correa viewed it as just another pile of dirt thrown on the kids’ heads. It was a step back to the way school used to be for them: mechanical and boring. To prevent cheating, a coordinator from the Ministry of Education oversaw the proceedings and took custody of the answer sheets at the end of testing. It felt like a military exercise, but as the kids blasted through the questions, they couldn’t help noticing that it felt easy, as if they were being asked to do something very basic.

Ricardo Zavala Hernandez, assistant principal at José Urbina López, drinks a cup of coffee most mornings as he browses the web in the admin building, a cement structure that houses the school’s two functioning computers. One day in September 2012, he clicked on the site for ENLACE, Mexico’s national achievement exam, and discovered that the results of the June test had been posted.

Zavala Hernandez put down his coffee. Most of the classes had done marginally better this year—but Paloma’s grade was another story. The previous year, 45 percent had essentially failed the math section, and 31 percent had failed Spanish. This time only 7 percent failed math and 3.5 percent failed Spanish. And while none had posted an Excellent score before, 63 percent were now in that category in math.

The language scores were very high. Even the lowest was well above the national average. Then he noticed the math scores. The top score in Juárez Correa’s class was 921. Zavala Hernandez looked over at the top score in the state: It was 921. When he saw the next box over, the hairs on his arms stood up. The top score in the entire country was also 921.

He printed the page and speed-walked to Juárez Correa’s classroom. The students stood up when he entered.

“Take a look at this,” Zavala Hernandez said, handing him the printout.

Juárez Correa scanned the results and looked up. “Is this for real?” he asked.

“I just printed it off the ENLACE site,” the assistant principal responded. “It’s real.”

Juárez Correa noticed the kids staring at him, but he wanted to make sure he understood the report. He took a moment to read it again, nodded, and turned to the kids.

“We have the results back from the ENLACE exam,” he said. “It’s just a test, and not a great one.”

A number of students had a sinking feeling. They must have blown it.

“But we have a student in this classroom who placed first in Mexico,” he said, breaking into a smile.

Paloma received the highest math score in the country, but the other students weren’t far behind. Ten got math scores that placed them in the 99.99th percentile. Three of them placed at the same high level in Spanish. The results attracted a quick burst of official and media attention in Mexico, most of which focused on Paloma. She was flown to Mexico City to appear on a popular TV show and received a variety of gifts, from a laptop to a bicycle.

Juárez Correa himself got almost no recognition, despite the fact that nearly half of his class had performed at a world- class level and that even the lowest performers had markedly improved.

His other students were congratulated by friends and family. The parents of Carlos Rodríguez Lamas, who placed in the 99.99th percentile in math, treated him to three steak tacos. It was his first time in a restaurant. Keila Francisco Rodríguez got 10 pesos from her parents. She bought a bag of Cheetos. The kids were excited. They talked about being doctors, teachers, and politicians.

Juárez Correa had mixed feelings about the test. His students had succeeded because he had employed a new teaching method, one better suited to the way children learn. It was a model that emphasized group work, competition, creativity, and a student-led environment. So it was ironic that the kids had distinguished themselves because of a conventional multiple-choice test. “These exams are like limits for the teachers,” he says. “They test what you know, not what you can do, and I am more interested in what my students can do.”

Like Juárez Correa, many education innovators are succeeding outside the mainstream. For example, the 11 Internationals Network high schools in New York City report a higher graduation rate than the city’s average for the same populations. They do it by emphasizing student-led learning and collaboration. At the coalition of Big Picture Learning schools—56 schools across the US and another 64 around the world—teachers serve as advisers, suggesting topics of interest; students also work with mentors from business and the community, who help guide them into internships. As the US on-time high school graduation rate stalls at about 75 percent, Big Picture is graduating more than 90 percent of its students.

But these examples—involving only thousands of students—are the exceptions to the rule. The system as a whole educates millions and is slow to recognize or adopt successful innovation. It’s a system that was constructed almost two centuries ago to meet the needs of the industrial age. Now that our society and economy have evolved beyond that era, our schools must also be reinvented.

For the time being, we can see what the future looks like in places like Juárez Correa’s classroom. We can also see that change will not come easily. Though Juárez Correa’s class posted impressive results, they inspired little change. Francisco Sánchez Salazar, chief of the Regional Center of Educational Development in Matamoros, was even dismissive. “The teaching method makes little difference,” he says. Nor does he believe that the students’ success warrants any additional help. “Intelligence comes from necessity,” he says. “They succeed without having resources.”

More than ever, Juárez Correa felt like the burro in the story. But then he remembered Paloma. She had lost her father and was growing up on the edge of a garbage dump. Under normal circumstances, her prospects would be limited. But like the burro, she was shaking off the clods of dirt; she had begun climbing the rising mound out of the well.

A Brief History of Alternative Schools

New research shows what educators have long intuited: Letting kids pursue their own interests sharpens their hunger for knowledge. Here’s a look back at this approach.

470 BC
Socrates is born in Athens. He goes on to become a long-haired teacher who famously let stu­dents arrive at their own conclusions. His questioning, probing approach—the Socratic method—endures to this day.

1907
Maria Montessori opens her first Children’s House in Rome, where kids are encouraged to play and teach themselves. Americans later visit her schools and see the Montessori method in action. It spreads worldwide.

1919
The first Waldorf school opens in Stuttgart, Germany. Based on the ideas of philos­opher Rudolf Steiner, it encourages self-motivated learning. Today, there are more than 1,000 Waldorf schools in 60 countries.

1921
A. S. Neill founds the Summerhill School, where kids have the “freedom to go to lessons or stay away, freedom to play for days … or years if necessary.” Eventually, such democratic schools appear around the world.

1945
Loris Malaguzzi vol­unteers to teach in a school that parents are building in a war-torn Italian village outside Reggio Emilia. The “Reggio Emilia approach”—a com­munity of self-guided learning—is born.

1967
Seymour Papert, a protégé of child psychologist Jean Piaget, helps create the first version of Logo, a programming language kids can use to teach themselves. He becomes a lifelong advocate for tech­nology’s role in learning.

1999
Sugata Mitra conducts his first “hole in the wall” experiment in New Delhi, India. On their own, slum kids teach themselves to use a computer. Mitra dubs his approach minimally invasive education.

2006
Ken Robinson gives what will become the most frequently viewed TED Talk ever: “How Schools Kill Creativity.” Students should be free to make mistakes and pursue their own creative interests, Robinson argues.

2012
The Common Core, a new set of curriculum standards that include student-centered learning, is adopted by 45 US states. Math students, say, should “start by explaining to themselves the meaning of a problem.”
