The shift from the perception of the child as innocent to the perception of the child as competent has greatly increased the demands on contemporary children for maturity, for participating in competitive sports, for early academic achievement, and for protecting themselves against adults who might do them harm. While children might be able to cope with any one of those demands taken singly, taken together they often exceed children's adaptive capacity.

Modern children were considerably less innocent than parents and the larger society supposed, and postmodern children are less competent than their parents and the society as a whole would like to believe. . . . The perception of childhood competence has shifted much of the responsibility for child protection and security from parents and society to children themselves.

The idea of childhood as a social invention, in retrospect, is hardly credible. In the Bible, in writings of the Greeks and Romans, and in the works of the first great educator of the modern era, Comenius, children were recognized as being both different from adults and different from one another with respect to their stages of development. To be sure, the scientific study of children and the increased length of life in modern times have enhanced our understanding of age differences, but they have always been acknowledged.

Young children learn in a different manner from that of older children and adults, yet we can teach them many things if we adapt our materials and mode of instruction to their level of ability. But we miseducate young children when we assume that their learning abilities are comparable to those of older children and that they can be taught with materials and with the same instructional procedures appropriate to school-age children.

It makes little sense to spend a month teaching decimal fractions to fourth-grade pupils when they can be taught in a week, and better understood and retained, by sixth-grade students. Child-centeredness does not mean lack of rigor or standards; it does mean finding the best match between curricula and children's developing interests and abilities.

Many older wealthy families have learned to instill a sense of public service in their offspring. But newly affluent middle-classparents have not acquired this skill. We are using our children as symbols of leisure-class standing without building in safeguards against an overweening sense of entitlement--a sense of entitlement that may incline some young people more toward the good life than toward the hard work that, for most of us, makes the good life possible.
