Realism is a philosophy that believes reality exists independently of human minds. It focuses on physical objects and truth that can be observed. Realists believe we can understand reality through careful observation and experimentation. Aristotle was an early proponent of realism, believing forms of objects do not change and logic is needed to reason about the physical world. In education, realism emphasizes teaching facts, basic skills, and practical knowledge through demonstration and recitation, with a focus on science, math, and standardized curricula.
