The document discusses common sense from philosophical and scientific perspectives. Philosophers like Plato believed true knowledge comes from reason beyond appearances, while Descartes assessed the role of first principles of common sense. Scientifically, Aristotle viewed science as moving from observations to general connections, while later scientists like Kepler, Galileo and Newton founded modern science by distrusting sense experience. Cognitive scientists believe the mind has intuitive theories for understanding the world. As educators, teachers must manage analytical thinking to apply common sense in lessons for student understanding, and teacher management is important for coordinating individual efforts to accomplish goals.
