PRESENTATION OUTLINE
"Education is discovering the brain and that's about the best news there could be...
Anyone who does not have a through, holistic grasp of the brain's architecture, purposes, and many ways of operating is as far behind the times as an automobile designer without a full understanding of engines." Leslie Hart, Human Brain and Human Learning (1983/1999, p. xi).
The brain is the most complicated organ in the world. It consists of more than one hundred billion neurons and a trillion supporting cells. Every neuron is connected to hundreds, perhaps thousands of other neurons forming complex networks. These networks make more connections than stars in universe. The brain occupies only 2 percent of body’s weight but uses 20 percent of the oxygen taken into the body. If you were to compare a piece of brain tissue to a sand grain at the beach, that tiny space would occupy about 100,000 neurons (Amen, 2001).
