Articles preschoolers

Read a roundtable with its founders here, or see new stories in the Human Interest section. New research shows that teaching kids more and more, articles preschoolers ever-younger ages, may backfire.

Ours is an age of pedagogy. Anxious parents instruct their children more and more, at younger and younger ages, until they’re reading books to babies in the womb. They pressure teachers to make kindergartens and nurseries more like schools. So does the law—the 2001 No Child Left Behind Act explicitly urged more direct instruction in federally funded preschools. There are skeptics, of course, including some parents, many preschool teachers, and even a few policy-makers.

Shouldn’t very young children be allowed to explore, inquire, play, and discover, they ask? Perhaps direct instruction can help children learn specific facts and skills, but what about curiosity and creativity—abilities that are even more important for learning in the long run? What do we already know about how teaching affects learning? Not as much as we would like, unfortunately, because it is a very difficult thing to study. You might try to compare different kinds of schools. But the children and the teachers at a Marin County preschool that encourages exploration will be very different from the children and teachers in a direct instruction program in South Side Chicago.

Developmental scientists like me explore the basic science of learning by designing controlled experiments. We might start by saying: Suppose we gave a group of 4-year-olds exactly the same problems and only varied on whether we taught them directly or encouraged them to figure it out for themselves? Would they learn different things and develop different solutions? In the first study, MIT professor Laura Schulz, her graduate student Elizabeth Bonawitz, and their colleagues looked at how 4-year-olds learned about a new toy with four tubes. Each tube could do something interesting: If you pulled on one tube it squeaked, if you looked inside another tube you found a hidden mirror, and so on. For one group of children, the experimenter said: “I just found this toy!

All of the children pulled the first tube to make it squeak. The question was whether they would also learn about the other things the toy could do. The children from the first group played with the toy longer and discovered more of its “hidden” features than those in the second group. In other words, direct instruction made the children less curious and less likely to discover new information.
