EdTech Effect Sizes Explained

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.
