More than a century ago, as nations were moving toward compulsory education for all children, educators were surprised to learn so many normal-appearing children met with frustration and failure.
The French minister of education commissioned Binet and Simon to find an explanation, which resulted in a test that measured a child's intelligence or her or his ability to learn in school. A century of research provides amazing knowledge on learning ability.
At mid-century, Donald Hebb gave neuroscientists an elegant theory: The brain develops by experience - by being used!
This theory stimulated several hundred studies. Infant animals raised in enriched environments had brains that differed markedly from the brains of infants raised in impoverished environments. Animal brains in enriched environments had more connections between brain cells, more chemical needed for synapse functioning, more gial cells to nourish the brain and larger brains.
The animal, through its activity, became the architect of brain development. These early years were crucial.
The Carnegie Council on Education concluded its five-year study with this statement: "The greatest single harm to children is poverty." The major determinant of successful schools is successful families. U.S. schools are hurt when children arrive at school lacking the intelligence to learn.
Schools work with the children parents provide them. "Schools in the United States are hurt when children arrive at kindergarten with underdeveloped brains because our nation has the highest level of poverty among advanced industrial nations, and its rate of poverty is more than twice that of comparable nations." (Patterson, Thomas, American Democracy, page 531).
The United States has substantial income inequality. The top 20 percent of citizens receive half the total income, while the other 80 percent get the other half. The bottom 20 percent receive less than 5 percent of the income and most live in serious poverty.
Our democracy does not carry out our moral obligation to our neighbor but creates the possibility for us to do so. As citizens we need to shift the blame for poverty from the characteristics of the poor to the failings of our economy, government and culture.
We must not expect schools and teachers to do things they can't do: care for children before they arrive at kindergarten.
