Schools are increasingly adopting a “one-to-one” policy of giving each child a digital device — often an iPad — and most students in the U.S. now use digital learning tools in school. There’s near-universal enthusiasm for technology on the part of educators. Unfortunately, the evidence is equivocal at best.

It looks like the most vulnerable students can be harmed the most by a heavy dose of technology — or, at best, not helped. Why are these devices so unhelpful for learning? Various explanations have been offered. When students read text from a screen, they absorb less information than when they read it on paper, for example. But there are deeper reasons, too. Unless we pay attention to these, we risk embedding a deeper digital divide.
