The document discusses brain-based learning and argues that understanding how the brain learns is critical for effective education. It states that some classrooms employ "brain-antagonistic" practices that can prevent learning, while brain-compatible education considers how the brain naturally learns. The author Leslie Hart pushes that if classrooms are meant for learning, they must accommodate the brain as the organ of learning. Hart argues teachers should apply principles of how the brain learns to create brain-fitting instructional settings and emphasize real-world exposure over dreary classrooms detached from reality. The document then lists 12 principles of how the brain learns and 3 conditions necessary for learning. It stresses the importance of a brain-compatible teacher who understands these principles and strategies
