Edtech's Shadow: Are Screens Harming Our Kids?

Neuroscientist Jared Cooney Horvath contends that educational technology is undermining children's learning and cognitive development. He notes a concerning trend since 2000 where IQ scores and international test performance have declined, even as screen-based learning in schools has dramatically increased.

Horvath highlights research showing that students spending over six hours daily on screens at school scored significantly lower on assessments. This aligns with his book, 'The Digital Delusion,' which posits that Western societies are witnessing a decrease in cognitive capability compared to previous generations.

However, experts like Professor Rose Luckin and Daisy Christodoulou offer a more nuanced view. They acknowledge that much edtech was implemented without robust evidence but argue that moderate screen use can be beneficial, with only the heaviest use showing negative outcomes. Dylan Wiliam emphasizes that current correlational studies cannot definitively prove causation, stating that edtech's impact varies and the key question is when it actually aids learning.
