The document discusses Brain-Based Learning Theory, which argues that instruction should be designed to fit with how the brain naturally learns. It outlines 12 Brain/Mind Learning Principles developed by Renate Caine and Geoffrey Caine, including that the brain is a complex system that learns through patterns and meanings, and that emotions are critical to learning. The theory suggests application through "Orchestrated Immersion," "Active Processing," and experiences that promote "Relaxed Alertness."
