Every child starts out home-schooled. Only later do parents decide whether their children will continue their education at home, or enter a public, private or parochial school. What happens in the home environment in those early years has a profound effect on a child's development because of the nature of brain development, and the nature of learning.
The first five years comprise the most rapid period of brain growth outside the womb.
"[A] newborn's brain is only about one-quarter the size of an adult's. It grows to about 80 percent of adult size by three years of age and 90 percent by age five. This growth is largely due to changes in individual neurons, which are structured much like trees. Thus, each brain cell begins as a tiny sapling and only gradually sprouts its hundreds of long, branching dendrites. Brain growth (measured as either weight or volume) is largely due to the growth of these dendrites, which serve as the receiving point for synaptic input from other neurons." (Zero to Three)
That means that 86% of the brain growth that occurs after birth transpires within the first five years of life. This remarkable, rapid growth occurs in response to stimuli:
"Brain development is "activity-dependent," meaning that the electrical activity in every circuit—sensory, motor, emotional, cognitive--shapes the way that circuit gets put together. Like computer circuits, neural circuits process information through the flow of electricity. Unlike computer circuits, however, the circuits in our brains are not fixed structures. Every experience--whether it is seeing one's first rainbow, riding a bicycle, reading a book, sharing a joke--excites certain neural circuits and leaves others inactive. Those that are consistently turned on over time will be strengthened, while those that are rarely excited may be dropped away. Or, as neuroscientists sometimes say, "Cells that fire together, wire together."" (Zero to Three)
The ways parents engage their children during those early years affects the physical structure of the brain, shaping the capacities that they will have for the rest of their lives.
The first five years are equally as critical to the development of character because of the nature of learning. In the early years of life, a child learns from his parents how to make sense of the world by exploring the answers to these questions.
- What is real? Is what we can see all that really exists? Are germs real even though I can't see them?
- What is true? Do my actions really have consequences? What if I take a cookie when Mom isn't looking?
- What is good? Does it matter what I do? Why do my parents teach me not to throw litter on the ground?
- What is beautiful? Is it better to look good, or be good? Is sharing your lunch with a friend who is hungry foolish or beautiful?
The answers that a child settles on during this critical window become the lens through which she sees the world. For example, if Dad frequently warns, "If you throw sand again, we're leaving the playground," but never follows through, the child learns that Dad's words don't match with reality. By contrast, if Dad models and expects polite language like "please" and "thank you," the same child will learn that these are the norms for respectful conversation.
Since the first five years have such a profound influence on brain development and character formation, the question is inescapable: Can any vision of education be successful without regarding parents as primarily responsible for the education of their children?
