Book excerpt: Creating a healthy, social classroom environment. This book explains how the brain, as a social organism, learns best throughout the lifespan, from our early schooling through late life. Positioning the brain as distinctly social, Louis Cozolino helps teachers make connections to neurobiological principles, with the goal of creating classrooms that nurture healthy attachment patterns and resilient psyches. Cozolino investigates what good teachers do to stimulate minds and brains to learn, especially when they succeed with difficult or “unteachable” students. He explores classroom teaching from the perspectives of social neuroscience and interpersonal neurobiology, showing how we can use the findings from these fields to maximize learning and stimulate the brain to grow. The book will have relevance to anyone concerned with twenty-first century learners and the social and emotional development of children.
