The basic discipline in educational science that studies the laws, principles and methods of education. Pedagogy can be divided into preschool pedagogy, general pedagogy, higher pedagogy, amateur pedagogy and special children pedagogy. Generally speaking, pedagogy refers to general pedagogy. The contents of general pedagogy include basic education theory, teaching theory, moral education theory, physical education, aesthetic education and school management. Pedagogy is comprehensive, theoretical and practical. We should use the knowledge of philosophy, politics, economics, sociology, physiology, psychology, pathology and hygiene to conduct a comprehensive study of education, so as to reveal the laws of education, demonstrate the principles of education, explain educational methods and guide educational practice.

Educational technology is a research field that properly uses relevant means and methods to improve educational performance. It forms a complete definition system of educational technology with three subordinate concepts at different levels. Educational technology is a subject that studies the theories, laws and methods of improving educational performance by using related technologies. It is a comprehensive applied discipline with methodological nature at the technical level of pedagogy, and it is a bridge connecting educational science, education and teaching practice. The discipline of educational technology should be the first-level discipline of pedagogy. Because of the duality of its logical starting point and the dual nature of the discipline of educational technology itself, the major of educational technology, which is to train educational technology professionals, should be "dual positioning and diversified development".
