Kerry Dickinson, who was instrumental in changing homework policy in her Danville, California, community last year, sent me an interesting article on how homework effects the brain.
“Once the frontal lobes start to develop, teenagers start being able to handle higher-level, more abstract concepts,” says Istvan Molnar-Szakacs, research neuroscientist at the UCLA Semel Institute’s Tennenbaum Center for the Biology of Creativity.
“The fiber tracts—highways that carry information from the sensory areas of the brain to the frontal lobes, and back again—have to be paved for information to travel.”
Molnar-Szakacs explains that the paving, known as myelination, is the process by which the fiber tracts are insulated. With more learning comes more paving, and as the pathways become more efficient, the brain gets better at integrating information.
