School is starting, and students across the country are about to spend a lot of time in the classroom and in the library. And as they crack their textbooks open, they’re going to hear a lot of familiar advice about how to study right. (16) " Sit still, in a quiet place. Avoid distractions. Keep your focus on the book. Put away your devices. Study in the same place every day. Practice discipline and make studying into a routine. "
    But that’s not the only way to learn, and brain science is increasingly suggesting alternatives. Benedict Carey, who covers medicine and science for the New York Times, is the author of How We Learn. He says that many of the old sayings about studying and focus are outdated. A lot of people think learning is all disciplined. And it turns out scientists have discovered that it doesn’t work that way. (17) A lot of things we’ve learned, whether it’s to cook or ride a bicycle or socialize, we’ve done those piece by piece. The brain is very good at learning on the fly during daily life. Distraction is one of those things everybody is worried about. However, there’s a whole bunch of science looking at problem-solving. In problem-solving, when you get stuck, you’ve run out of ideas, distraction is really your best friend. (18) You need to stand up, let it go—walk around the block, go to the cafe, drink a beer, whatever it is—and that is really your best shot at loosening the gears a little bit and allowing yourself to take a different and more creative approach to the problem.
