Professor Ping Li and others think in the article "Where is the Puzzlement of Education-Reflection on Educational Idea": "Educational idea is an ideal, eternal and spiritual paradigm about educational development. The educational concept reflects the essential characteristics of education and fundamentally answers why education should be run. " (Note: Ping Li and Zhong Minghua: "Where is the Puzzlement of Education-Reflections on Educational Ideas", Shanghai Higher Education Research, No.5, 1998. The so-called essential feature of education is that education is the fundamental feature that distinguishes practical activities from other social activities. Therefore, Professor Ping Li put forward his educational thought from the perspective of educational ontology and epistemology, that is, from a basic category of educational philosophy. Professor Chen Guisheng's understanding of educational thought is very unique. (Note: See Chen Guisheng's Discrimination of Pedagogy Horizon, East China Normal University Press, 1997, p. 4- 12. In his book Analysis of Pedagogy, he pointed out that there is a phenomenon of "generalization" of educational concepts in pedagogy sentences, which is mainly caused by the confusion between educational concepts, especially the confusion of replacing educational concepts with educational concepts. He cited the concepts of "curriculum" and "teaching" as examples to illustrate this phenomenon.
