Educational attainment is part of human development, and fundamentally this is a biological process that cannot be sped up. We cannot wish away our biological limitations because we find them inconvenient. Children will learn crawling, walking, listening, talking and toilet training, all in succession at developmentally appropriate ages. Once in school, for skills that require performing a physical task, that are in what Bloom's Taxonomy classifies as the "psychomotor domain," it is understood that children will only learn when they are physically and developmentally ready. No one expects four-year olds to type fluently on a computer keyboard, play difficult Chopin Etudes on the piano, prepare elaborate meals in the kitchen or drive a car.
