Ep 62. Why more classroom technology is making students learn less

In this episode, Anna is joined by Dr. Jared Cooney Horvath, a cognitive neuroscientist, educator, and bestselling author of The Digital Delusion. They examine what decades of research and international data reveal about classroom technology, screens, multitasking, attention, and memory, and why more technology often leads to less learning.
Jared explains how offloading knowledge to devices can undermine higher-order thinking, why human teachers’ expertise, and practice, remain central to learning, and when technology may help or hinder students. The conversation also tackles how schools and families can navigate an increasingly tech-saturated education system.
This is a thoughtful, evidence-informed episode for educators, parents, and anyone questioning whether digital tools in the classroom are helping students learn or holding them back.

[00:00:00] Anna Stokke: Welcome to Chalk & Talk, a podcast about education and math. I'm Anna Stokke, a math professor and your host. Welcome back to another episode of Chalk & Talk.
This episode is available in both audio and video. You'll find a link to my YouTube channel in the show notes and please do give the show a follow-on YouTube. Before we get started, I'd like to acknowledge new support through a grant from La Trobe University.
This support helps me to continue to share evidence informed conversations that connect research with practise and advance the goal of improving student learning, particularly in math. I've got an important episode today. My guest is Dr. Jared Cooney Horvath, a cognitive neuroscientist, educator and bestselling author.
His new book, The Digital Delusion, examines the impact of classroom technology on learning and raises serious questions about whether screens in schools may be harming learning. In this conversation, we examine what decades of research and international data tell us about screens, multitasking, attention and memory. Jared explains why more technology often leads to less learning, how offloading knowledge to technology undermines higher order thinking, and why human teachers' knowledge and practise remain central to learning at every age.
We also discuss when technology may be helpful and when it's not, and what this means for educators and parents navigating a tech saturated education system. This episode raises serious questions about what the widespread use of education technology may be doing to learning and what we can do about it. I found this conversation informative and thought provoking, and I hope you do too.
Now, on with the show. I'm delighted to be joined today by Dr. Jared Cooney Horvath. He is a cognitive neuroscientist, an educator and bestselling author of several books.
His latest book is called The Digital Delusion, How Classroom Technology Harms Our Kids' Learning and How to Help Them Thrive Again. And it was just released in December. He has a PhD in cognitive neuroscience from the University of Melbourne and has expertise in human learning and memory and brain stimulation.
He currently serves as an honorary researcher at the University of Melbourne and St. Vincent's Hospital in Melbourne. Jared works at the crossroads between the lab and the classroom, spending most of his time working directly with teachers and students or helping schools, organisations and companies improve learning and engagement. His research has been featured in popular publications, including The New York Times, Wired, BBC, The Economist and PBS's Nova.
And I'm really looking forward to talking to him today about his great new book. Welcome Jared. Welcome to the podcast. It's great to have you here.
[00:03:19] Jared Cooney Horvath: It's awesome to be here, Anna. Thank you so much for having me on.
[00:03:21] Anna Stokke: I was lucky to get an advanced copy of your book, and I read the whole thing cover to cover. And I want to say it's a great book. It's a fascinating read.
It's troubling, but it's fascinating. And I think it's an important read for any parent or educator. So, we're going to talk a lot about that today.
Let's set the scene. The screens are everywhere, including in schools. And your book specifically takes a critical look at the promises of edtech.
You start by arguing that we do have a problem, that there's evidence that edtech harms learning. You then explain why, drawing on your background in neuroscience, and then you give practical advice for what we can do about it. So, would you say that sort of summarises the roadmap in the book?
[00:04:06] Jared Cooney Horvath: That sounds perfectly right. I went with the data mechanisms applications angle to it, because data only says so much. Mechanisms gives you a good grounding, but then everyone says, cool, so what? I hopefully we answered some of those questions too.
[00:04:20] Anna Stokke: You open the book with this hard-hitting statement, our children are less cognitively capable than we were at their age. And you argue that Gen Z, that's the cohort between around 1997 and 2012. Is that right?
[00:04:37] Jared Cooney Horvath: Yeah, right around 2012 was when we flipped into Gen A.
[00:04:40] Anna Stokke: You argue that Gen Z is less healthy, less happy and less knowledgeable than previous generations.
And I have two children that are Gen Z, by the way.
[00:04:50] Jared Cooney Horvath: I'm not trying to make a bad argument.
This is average of all kids across that generation. So, there will be some who are flying and some who are absolutely sinking. But in the middle, by and large, we're seeing declines in basically every base of cognitive measure we would care about.
[00:05:05] Anna Stokke: Can you walk us through some of the evidence behind that claim?
[00:05:08] Jared Cooney Horvath: I think if you take a look, there was a book recently called The Anxious Generation, which I think most people read. That shows a lot of great statistics about the health and the happiness angle of the next generation. Kids are just far more lonely than we ever were.
And this is not their fault. This is the world that we've built around them. The food they eat is not good for them.
The sedentary lifestyle has not been good to them. I mean, you've got kids with eye and back problems before they hit teenage years. That ain't great.
