Realism is a philosophy that views the world as real and material. It originated from Greek philosophy. Major proponents include Francis Bacon, John Locke, Aristotle, Aquinas. Realism in education aims to prepare students for real life through practical curriculum focusing on basics, using structured teaching methods like Herbart's five steps. The teacher's role is to have subject knowledge and inspire students. However, critiques say it overemphasizes the physical world neglecting imagination and ideals.
