The purpose of education is determined by the ruling class, because education is an activity, so we should set in advance what kind of education and educational purpose we want to establish. In order to ensure the smooth progress of educational purposes, we need to design a set of norms. Therefore, the purpose of education and the education system should be done together. What do you think education is? What is the use of education? What kind of education are we going to do? Of course, there is another important question: who will teach? If we take education as the research object, we should generally study it from several aspects. Strictly speaking, our introduction to pedagogy studies the first three questions. What is education? Is the essence of education. What is the use of education? It is the function of education. Our education plays an important role in social development and human development. The third aspect says what kind of education, educational purpose and educational system we want to run. If the first three questions about the introduction of basic education are similar. Then the last two questions are how to teach in our future courses, including many questions about what to teach, all of which are curriculum problems. How to teach is the problem of classroom teaching.
