Chapter 1: What is the main concern about AI in education?
You're listening to TED Talks Daily, where we bring you new ideas to spark your curiosity every day. I'm your host, Elise Hu. No two humans learn in exactly the same way. So what might happen when machines help us develop better tools to create personalized pathways to learning?
In this talk, AI education entrepreneur Priya Lakhani shows us how a one-size-fits-all approach to the classroom strains teachers and fails students, and how, if properly designed, AI could amplify what students and teachers do best and reveal how irreplaceable we humans truly are.
Twenty years ago, I founded a social enterprise. I wanted to change the world. And we were funding millions of meals to the underprivileged. We were providing tens of thousands of vaccines across parts of Africa. And we were funding schools in the slums of India. Now, I thought that I was doing quite a good job and having a lot of impact in all of these areas. Until one day ...
I was working with ministers in the UK, and they said that 20 percent of students leave secondary schools in the UK, and they're not able to read and write well enough. Now, I thought, with brick-and-mortar schools and qualified teachers, if they're not able to do that in the UK, then I'm not having the impact that I wanted to have in those schools in the slums in India. So what's going on?
What's the problem? We need to fix it. So I went to schools. I went to schools and I asked lots of questions, and I found two critical problems on the front line of education. The first is that they continue to have the one-size-fits-all delivery of education to a classroom of around 30 to 35 people. The second, I think you will agree with me, should be headline news every single day.
Seventy-four percent of teachers want to quit their jobs in the next three years. Why?

Chapter 2: How can AI personalize learning experiences for students?
It's because of workload. They spend so much time micro-marking, micro-assessing, trying to figure out where every child is at. They are teachers by day, and they are data analysts by night, and not one of them signed up to do that night job.
So walking around schools, I had a smartphone in my hand, and we had machine learning applications telling us how we should shop, how we should save, and how we should sleep. And I thought, why don't we have this technology in the classroom telling us how we should learn? We've got to build that technology. But we can't use any old machine learning recommendation engine.
We need to combine artificial intelligence with neuroscientific theory and the learning sciences to learn how every single brain in this room learns. Because if we can fix learning, we can improve outcomes. We can personalize education for every single one of us and provide intelligent insights to teachers to reduce the workload. So 12 years ago, I built a team. They built the technology.
It exists. Students use it in over 140 countries. We've collected over 40 billion data points on how children learn. And I'm going to show you a couple of the things that I've learned about learning on the way. But before I do that, I thought it would be really important to share with you some student feedback that I have on our platform.
It's really important because it tells us what children's expectations are when they use an AI education partner. So I get feedback like this. I'm trying to say, thank you, it's lovely, it's brilliant. I think Century will help me to achieve things that I thought were impossible. It's a golden child, right? My life's purpose has been fulfilled.
And then these sweet, lovely, innocent children send me messages like this. I don't like this website. It makes me able to do my homework. LAUGHTER Wait. And then I'm being bribed. I will give you 100,000 pounds. I'm not joking. You just need to give me no work. Give me a button to do the work for me.
Now, these children and that sentiment very much ties in with a recent survey where children were asked, how do you use AI LLMs, chatbots, with your homework? a staggering fifth of children admitted they get AI to do all of their work for them. So they're not using AI to help them learn, they're using AI to actively avoid learning.
Now, I know some of you are frowning right now, thinking, how dare they? I don't think they're that different from us. Think about how we felt when we first used ChatGPT. I think that you all felt euphoric. You thought, wow, I'm going to look like a genius. I never need to do any work ever again. This is amazing. Yeah.
And then it hallucinated and confabulated, and you were like, big tech, seriously, you had one job to do, Sam Altman, with all that money, and it's making stuff up, right? And then for the lawyer who shared it in a courtroom and got fined, sheer humiliation and embarrassment for those people. And I think we've ended up with this sort of sinking realization of acceptance, right?

Chapter 3: What are the critical problems faced by teachers today?
And then the fourth is reflection. When we reflect on our work and we are given structured feedback in three very specific ways. How am I learning right now? What is my learning goal? And then what are the gaps to get to that goal? What do I need to do? Those students improve their outcomes. Now, you'll find that these four techniques have something in common. They are harder.
They all involve a productive struggle. We know sustained mental effort strengthens the parts of the brain, and it's positively correlated with growth in the brain. There was an amazing study in my home city of London with black taxi drivers. Now, if you're a cabbie in London, you have to pass a test called a knowledge. You have to memorize 26,000 streets in the city of London.
You're not allowed to use navigation apps. Now, wow, exactly, right? Isn't that crazy? Yeah, no Uber drivers for them, right? And so neuroscientists scanned their brains, and they found that parts of the hippocampi in the brain, this is the part of the brain that's responsible for spatial memory and navigation, were larger in parts with experienced cabbies.
because you have to build all of those mental models, you have to generate new routes every time you have a new passenger. And so they say that that growth, because of the positive correlation with what they have to do, is really meaningful and telling, and it is no different for learning. Durable learning does not come from shortcuts.
It comes from certain types of effort, and this is why AI is amazing for education, because AI can spot patterns in how we all learn. It can spot patterns in how concepts across subjects connect. It can predict if you don't know something and provide you with that material. at the right time. It can provide us with timely, targeted interventions and give teachers those insights.
It can predict when you're just about to forget something and give you that material at just the right time. It can force you to generate an answer rather than just reveal the answer. And it can provide amazing structured feedback against expertly designed rubrics from teachers. So AI well-designed can be phenomenal in education, and we've seen it work.
Now, a lot of people come to me, students and adults, and they say, but why bother? Because we've got GPS, right? We have AI, we can Google the answer to absolutely anything, so we don't need to do this anymore. That's not true. If you think about AI, AI is our history predicting our future. It is brilliant at spotting patterns in data.
It has been amazing as a partner in remarkable breakthroughs like drug discovery and protein folding, new materials and crystals. But the thing is, none of that happens with AI in isolation. We humans, we frame the questions, we set the goals, we chose the datasets, we decide which discoveries matter. Our knowledge is not just trivia. It is the raw material of thinking and discovery.
AI is not there to replace our expertise, it's there to allow our expertise to expand. And if you think about power to flight, penicillin, electricity, AI itself. Humans learned. They went through that productive struggle, right? They built domain expertise, and from that, they took a leap in their imagination, and they created innovations. So for students who want to cheat,
