Parents routinely remark that kids seem to be in their own little world. And if we watch carefully as they run around a playground, sit quietly and draw, or work out the rules of a game, it's clear that their choices are conscious, their interaction carefully orchestrated. Their "own little world" is one of their own deliberate creation. And what better way to understand this world than by viewing it from the inside -- which is just what author Corsaro did when he traded in his adult perspective for a seat in the sandbox alongside groups of preschoolers. To evaluate the state of childhood, many adults set their sights on the future.

When we do this, we effectively lose sight of what it's like to be a child. Indeed, missing from all the discussions on what is best for children are the voices of children themselves. For the first time, we have a spokesman to represent the views of children on childhood. Originally motivated by a desire to test traditional theories of child development, Corsaro approached his research with an open mind (although in retrospect he admits that, like most adults, he didn't start out taking the kids seriously enough). But he did believe that many experts often underestimated children's abilities. He just couldn't accept the notion that children were passive agents who are molded by adults.

He needed to enter their everyday lives -- to be the best kid he could be. The journey ofdiscovery on which Corsaro embarks as he lives among and is accepted by children is as fascinating as it is revealing. While Corsaro is quickly satisfied that kids aren't mere passive agents, he is astonished to learn that
