Just how do humans learn? And can science unlock secrets of the learning process that can help teachers and professors be more effective in their classrooms?

One of the latest people to tackle those questions is Josh Eyler, in a new book called How Humans Learn. But as Eyler warns readers at the outset, he’s not a scientist himself, but a humanist with a PhD in Medieval studies. And it turns out that is what makes the book such an interesting and unusual take on what is becoming a hot topic.

Eyler certainly spends a lot of time thinking about teaching these days, since his day job is now the director of the Center for Teaching Excellence at Rice University. And while his book offers plenty of practical tips, it doesn’t pretend to have all the answers. By offering a guided tour of a variety of theories on the question of human learning, he may just cause you to rethink what teaching even is.

We talked with Eyler about what surprised him most as he dove into the topic, and what he sees as examples of great teaching.
