"Structured learning certainly has its place. But if it crowds out direct, unmediated engagement with the world, it undercuts a child’s education. Children learn the fragility of flowers by touching their petals. They learn to cooperate by organizing their own games. The computer cannot simulate the physical and emotional nuances of resolving a dispute during kickball, or the creativity of inventing new rhymes to the rhythm of jumping rope. These full-bodied, often deeply heartfelt experiences educate not just the intellect but also the soul of the child. When children are free to practice on their own, they can test their inner perceptions against the world around them, develop the qualities of care, self-discipline, courage, compassion, generosity, and tolerance—and gradually figure out how to be part of both social and biological communities.
If children do not dip their toes in the waters of unsupervised social activity, they likely will never be able to swim in the sea of civic responsibility. If they have no opportunities to dig in the soil, discover the spiders, bugs, birds, and plants that populate even the smallest unpaved playgrounds, they will be less likely to explore, appreciate, and protect nature as adults."
