Comenius (1592- 1670) is a great bourgeois democratic educator in Czech Republic, the founder of modern western educational theory, and was born in a miller's family. When he was young, he was elected as the priest of the Czech Brotherhood and presided over the Brotherhood School. During the Thirty Years' War (1 18-65438+), he continued to engage in educational activities and social activities. He sharply criticized the call of medieval school education II to "teach everyone all knowledge", put forward a unified school system, advocated universal primary education, adopted class teaching system, expanded the categories and contents of disciplines, and emphasized the acquisition of knowledge from things themselves. Based on the principle of conforming to natural order and sensory theory, he put forward a series of teaching principles, such as intuition, thoroughness, self-awareness, enthusiasm, systematicness, gradualism and ability, and compiled a variety of teaching materials.
