There were many fine papers. I was especially interested in several presentations on brain research. The brain is a parallel processor. Learning engages a person's entire physiology. The search for meaning is innate, and occurs through patterning.
Emotions are critical to meaning making and patterning.
Every brain simultaneously perceives and creates parts and wholes. Learning involves both focused attention and peripheral perception. Facts and skills are remembered best when embedded in spatial memory. Learning is enhanced by challenge and inhibited by threat. Each brain is unique.
