Are Classroom Screens Helping Kids Learn, or Quietly Working Against Their Brains? with Neuroscientist Dr. Jared Cooney Horvath (#257)

Are classroom screens really helping children learn—or quietly working against how their brains develop?

In this episode, neuroscientist Dr. Jared Cooney Horvath joins us to discuss his new book The Digital Delusion and what the science actually says about technology in the classroom.

For years, schools have been told that more technology means better learning. But many of the ideas that built the EdTech movement—like “multimedia enhances learning,” “kids learn best on their own,” and “AI tutors can replace teachers”—were never strongly supported by evidence.

Dr. Horvath explains what the data actually shows about classroom technology, including the surprising cognitive tradeoffs of 1:1 devices, why handwriting and reading on paper still outperform screens for deep learning, and why the brain struggles with multitasking and constant digital interruptions.

We also explore the three biological drivers of learning—attention, empathy, and transfer—and why screens often disrupt all three.

Perhaps most importantly, we discuss developmental timing. Children’s brains are highly sensitive to environmental input, and heavy exposure to screen-based stimulation can shape reward pathways, condition dopamine systems, and increase vulnerability to compulsive screen use later in life.

Is it really possible to “moderate” highly stimulating screen activities? And what should parents do in a world where technology seems unavoidable?

If you’ve ever wondered whether all this classroom technology is truly helping your child—or quietly making learning harder—this conversation will give you the science, the context, and the reassurance parents need.

Because the goal of education isn’t just to use technology. It’s to help children learn deeply and prepare for life beyond the screen.
