The development of pedagogy has gone through the following stages: 1. Germination stage: the main feature is that pedagogy has not yet differentiated into an independent discipline from philosophy, politics and ethics. For example, Confucius, Mencius, Xunzi and Zhu in ancient China, Plato, Aristotle and quintilian in ancient western countries expounded various social phenomena as well as educational phenomena. They put forward their own philosophical and political views and some educational views. 2. The emergence of independent pedagogy: The main feature is that pedagogy has become an independent discipline in its primitive state. The publication of Great Teaching Theory by Czech educator Henri News marks the beginning of the formation of pedagogy as an independent discipline. 3. The establishment of Marxist pedagogy: pedagogy is developing in a scientific direction as a whole and locally. Representative figures include makarenko, Krupskaya and Yang Xianjiang. 4. Development of modern educational theory: With the progress of society and the modernization of production and technology, pedagogy is developing towards modernization. Representative figures are Bruner, zankov and Wa? Genschein, Bloom, etc.
