Comenius is an educator known as Copernicus in the history of modern education. Jan Amos Komensky, born in 1592 and died in 1670, was a Moravian Czech, a great Czech democratic educator and the founder of modern western educational theory, and was born in a miller's family. He was the earliest advocate of public education, and his thoughts were put forward in the book "On Great Teaching".

Biography: When he was young, he was elected as the pastor of the Czech Brotherhood and presided over the Brotherhood School. After the outbreak of the Thirty Years' War (16 18~ 1648), he was forced into exile for decades and continued to engage in educational and social activities. He sharply criticized the school education in the Middle Ages and called for "teaching all knowledge to all people". Put forward a unified academic system, advocate universal primary education, adopt a class teaching system, expand subject categories and contents, and emphasize the acquisition of knowledge from things themselves. His main works are Parenting School, Great Teaching Theory, Introduction to Language and Science, World Map, etc.

Educational thought: Comenius advocates universal compulsory education and "teaching everything to all mankind", which is actually to give preschool education and primary education to all children. Secondary education can only be enjoyed by men and women who are interested in mental work, while higher education is the right of a few "wise men". However, under the historical conditions at that time, Comenius broke the shackles of feudalism and advocated that everyone had the right to education, which was suitable for the development of social productive forces at that time.
