Are Classroom Screens Quietly Hurting Your Child’s Ability to Learn?
A neuroscientist explains why EdTech didn’t improve learning—it made it worse.
When I first read The Digital Delusion, I felt something I don’t often feel in this fight anymore: relief.
For years, parents have been saying something is off. Screens keep multiplying, yet outcomes keep declining. Kids aren’t learning the way they used to—or even what they need to. And despite everything educational technology promised, the gap between what we were sold and what our children actually got keeps growing.
But if parents point out this observation, they are often dismissed. If parents ask to pull their child off of screens and back to pen and paper, they are most often denied, with schools citing “engagement,” “digital literacy,” and “21st century skills.”
That’s exactly where Dr. Jared Cooney Horvath comes in. In his book The Digital Delusion, he does something ScreenStrong has always believed in: he walks straight into the buzzwords and dismantles them with data. Not opinion. Not gut feeling. Data. The kind drawn from an analysis of more than 21,000 studies across 91 countries. The kind of evidence that is hard to dismiss, even for the most screen-committed school administrator.
Parents, you were not overreacting. The proof is in the latest data on how tech affects learning and in the neuroscience of how the brain learns.
I still cannot stop thinking about my conversation with Dr. Horvath on the podcast last week; that’s why I want to highlight a few of his most important points in the Substack. I hope you will listen to the full interview if you haven’t already. It’s truly worth every minute.
We Put on a Band-Aid and Never Took It Off
I asked Dr. Horvath why he wrote the book. He didn’t hesitate:
“COVID hit. Everyone goes digital. COVID ends… and we stayed digital. It’s like we put on a Band-Aid and just never ripped it off when the wound had healed.”
Now nearly 90 percent of districts are one-to-one, meaning one laptop or iPad for every student. But here’s the question he keeps asking—and one I keep asking, too:
“If you understand how learning works, you realize these tools aren’t well aligned to human learning. They never have been.”
Never.
Education Wasn’t Broken. EdTech Broke It.
This is the part that stopped me cold.
The story we were told was that schools were failing and technology would fix them. But Dr. Horvath’s research tells a different story:
“Education was not broken. We were getting the highest results we’d ever gotten right when EdTech started telling us it was broken.”
And then: “If education today can be said to be broken, it’s because EdTech broke it.”
We didn’t need a digital overhaul. We replaced a golden era of learning with screens—and called it progress.
Engagement Is Not Learning
Parents know this intuitively. A child can be glued to a screen for hours and learn almost nothing. So why are districts so focused on keeping kids “engaged”?
Dr. Horvath puts it plainly:
“You can be wildly engaged and not learn a thing. . . or moderately engaged and learn a ton.”
High stimulation produces shallow processing. Shallow processing produces low retention. EdTech keeps eyes on screens. It does not build deep thinkers.
Screens Disrupt The Biology of Learning
Dr. Horvath, a neuroscientist, says that real, deep learning depends on three biological systems, and screens interfere with all three. In the podcast, he breaks down each:
Attention. The human brain is a serial processor, meaning it can only focus on one thing at a time. Yet we hand children a device optimized for rapid switching and then ask them to learn on it. Kids spend roughly 450 hours a year using screens for schoolwork. Kids spend more than 2,500 hours a year on those same screens multitasking for entertainment. So what are they really practicing? The one thing that kills learning: multitasking.
Empathy. Dr. Horvath explains that empathy isn’t just a feeling—it’s a biological synchrony between people. When two humans connect face-to-face, their hearts synchronize, their breathing aligns, and their brains coordinate. It’s beautiful to think about. And that synchrony drives motivation when learning gets hard. Screens have no biology. They cannot replicate it. This is why a strong student-teacher relationship remains one of the most powerful predictors of learning success—and why 85 percent of students in online courses drop out.
Transfer. The goal of education isn’t just to remember information, but to use it in the real world. But transfer depends heavily on context. When children learn primarily on screens, their knowledge tends to stay trapped there. They are not gaining skills that help them succeed in the real world. As Dr. Horvath says so well: “When you train online in the easiest environment possible, then try to perform offline—you’re toast.”
The Dopamine Trap
This is where parents feel it most viscerally: the irritability, the inability to sit still, the constant waiting to get back to the device.
Dr. Horvath explains this behavior in the context of a habit loop of cue, action, reward. We receive a cue to do something, we do that something, and we get a reward. Over time, dopamine shifts the loop so that the feeling of reward actually arrives before the action. And when that happens, a habit is transformed into a craving, or as Dr. Horvath says, “That’s a slot machine.”
Gamified learning uses dopamine in this way, flipping out children’s habit loops so they aren’t just distracted. They’re conditioned. They need the hit just to feel normal. That’s a whole lot closer to addiction than it is to learning. His Oregon Trail example is one I’ll never forget: “I can tell you every single button you need to press to play it. The one thing I don’t know is anything about the Oregon Trail. I learned the game. I did not learn the content.”
What Parents Can Do Right Now
Dr. Horvath’s honest, data-driven insights are just one highlight of the podcast. His practical advice is another and aligns with everything we teach at ScreenStrong. When it comes to protecting your children from EdTech, here’s his advice:
Do a tech audit with your kids. Sit down together and look honestly at how devices are being used, for how long, and what they’re replacing. Kids who understand the why behind limits are far more likely to internalize them. This isn’t a gotcha exercise. It’s a conversation.
Buy a printer. If your school district will not accommodate paper assignments, make them yourself. Print the digital curriculum. Print the digital homework. Hand it in on paper. As Dr. Horvath puts it: “The medium was never the point of K-12.” The point was always the knowledge. Get back to that.
Protect weekends. Recovery matters. The brain needs time away from screens to consolidate learning, restore attention, and just be a kid. “The weekend is as important as the weekdays,” Dr. Horvath says, so guard it like it counts—because it does.
Model what you expect. This one is uncomfortable, but it matters. In a survey done by the Girl Scouts of America, over 80 percent of girls say their parents’ screen use interferes with emotional connection. Our kids watch us constantly. If we want them to believe that presence matters and people come before devices, we have to live that out in front of them every single day.
Hear More From Dr. Horvath
This one line from the book summarizes the whole podcast perfectly:
“We didn’t realize how much these devices took from our kids until we took them back.”
Parents, you are not “behind the times.” You are not extreme. You are not anti-technology.
You are pro-brain. You are pro-childhood. You are pro-deep learning.
And that matters more than you know.

Update: reading this amazing book now - can't flip the pages fast enough!!!
These kids go from tech-heavy K-12 into fully remote college. Community college professor here, local public-funded school with most of our classes fully online with no synchronous instruction, not even Zoom.
When you talked about empathy - that was so validating. I teach public speaking - so when students give speeches, my role, my job, my vocation, is to look at them meaningfully. I give them empathy, live attention, etc. And in this presence I offer, they grow. It's like I am the sun, and they are a plant. It truly is that profound. I really believe that through my intentional attention and care, they improve.
When they stuck me online, I watch videos alone, and they create videos alone. They never see me see them. The empathy is missing. I try to type nice messages, and some are learning there, but the core heart of that educational transformation - love, empathy, caring, presence - is totally lost.
I have been looking for a way to prove that something is missing, but everyone is so focused on people completing ("completers") classes that no one is really asking the more profound questions.
Thank you so much for bringing insight and clarity to this pressing issue.
I know we focus here on kids, just wanted to share the sad truth that the problem keeps on going, unfortunately.
