While the number of cells stays the same, the number of connections or dendritic structures keeps accumulating. A twenty year old will solve the same problem faster than a six year old because the pathways between different cells are established. Development of these pathways is crucial to learning. When learning takes place, the brain is actually re-arranging the dendritic pathways. Dr. Lowery stated that learning is developmental and occurs in stages.
Understanding occurs when prior knowledge is accessed and new connections are made.
This occurs when learners construct knowledge for themselves. Looking beyond the structure of the brain, Professor Lowery cited research which had direct connections to classroom practice. Even reading scores are increased in hands-on classrooms. Yet, he lamented, despite the research, most of our classroom time is spent at the symbolic-narrative level. Dr. Lowery claimed there definitely is a place for it in learning most subjects.
