Education Week: Studies Find 'Easy' Material May Not Be Easy to Learn.
A growing body of cognitive research, including Mr. Kornell’s study and a series of experiments presented at the American Educational Research Association conference earlier this month, suggests challenging material and study strategies—called “desirable difficulties”—help students remember material better and longer. By contrast, trying to take the route that feels easier can lead students to develop study habits that they believe are helpful, but that actively interfere with their learning.
The findings suggest that it may not be enough to teach students study strategies. Educators also must help students think about why and how they learn while studying, researchers say.
