Neuroscience or Brain-Based Learning schools utilize approaches that educators believe are in accord with recent research on the brain and human learning. Advocates say the human brain is constantly searching for meaning and seeking patterns and connections. Authentic learning situations increase the brain’s ability to make connections and retain new information. A relaxed, non-threatening environment that reduces students’ fear of failure is considered by some to enhance learning. Research also documents brain plasticity, which is the brain’s ability to grow and adapt in response to external stimuli.
