1. From the universality and popularization of education, the position and role of teaching materials are becoming more and more important.

Under the background of the transformation from elite education to mass education, schools need a set of standards, norms, goals and requirements. Education emphasizes science and norms more than art and freedom. Therefore, teaching materials become the center of school education and the "reliance" and "reliance" to ensure the quality of school basic education. ?

2. From the operating mechanism of teaching activities, teaching, as an educational method, has incomparable advantages in systematically imparting knowledge and skills and cultivating subject learning ability. This advantage mainly depends on teaching materials.

Textbooks are the basis of teachers' teaching and students' learning. Herbart has long noticed that there is always a third party's thing that needs the attention of both teachers and students in teaching. This "third party" between teachers and students makes it impossible for us to be student-oriented and teacher-centered no matter how hard we try in teaching.

Textbooks not only define teachers' teaching tasks, but also define students' learning tasks. Textbooks are the real core of the teaching process. We must focus on teaching materials and give full play to the subjective initiative of teachers and students.

3. From the textbook itself, the textbook is not only the spokesman of curriculum standards, but also the professional wisdom and discipline level of many experts and scholars. It is the essence of subject knowledge and the crystallization of wisdom. Textbooks are not ordinary materials and reading materials. They are specially developed and compiled according to the educational purpose, the law of students' physical and mental development and cognitive characteristics, and are suitable for students at corresponding specific stages.

Problems in the use of teaching materials;

From the perspective of teaching practice, the marginalization and misreading of textbooks are the fundamental reasons for the low quality of classroom teaching and the confusion of teaching reform. The core task of classroom teaching is to solve the contradiction between teaching materials and students.

Therefore, it is necessary to organize classroom teaching activities centered on teaching materials. Without textbooks or classrooms that do not rely on textbooks, teaching will lose its connotation and direction, and quality will have no basis and foundation.

In particular, as far as specific classroom teaching activities are concerned, we must be textbook-based, faithfully and comprehensively teach the content of the textbook, so as not to dismember the textbook, not to be divorced from the textbook, not to marginalize the textbook, to teach the content of the textbook, to implement the textbook and to solve the textbook problems.

Even if the textbook is an example, it should be taught well and to the point. The supplement, extension, expansion and transcendence of the example, and the criticism and questioning of the example should be based on the example.
