Teaching is a bilateral activity between teachers and students. Teachers are educators, "educated first". Han Yu, a famous writer in the Tang Dynasty, wrote in On Teachers: "Ancient scholars must have teachers. Teacher, so preaching and teaching is also confusing. " This reveals a universal law in teaching work, that is, the "Tao" students hear, the "karma" they teach, and the "confusion" they solve through teachers. Teachers are entrusted by the society, representing social interests and fulfilling social requirements for teaching; He has received special training, is proficient in the professional knowledge he teaches, understands the physical and mental development of students, and knows how to organize and conduct teaching. In the process of teaching, he decides what to teach and how to teach, what direction and goal to organize teaching, and what kind of people to train. He is the organizer, enlightener and instructor of the whole teaching process. He can correctly guide students from the unknown to the known, from less to more, inspire students to keep thinking, and urge students to change from "need to teach" to self-study and self-study, so as to give full play to students' enthusiasm, initiative and consciousness in the teaching process. The exertion of students' learning initiative and enthusiasm depends on teachers' guidance, teaching, teaching art, teaching methods and teaching quality. For students, only with the help of teachers can they master scientific and cultural knowledge concisely and effectively, improve their physical and mental development level quickly, and make themselves become talents needed by society.
(2) Giving full play to students' main role is an important factor for teachers to teach effectively. In the process of teaching, students are not only the object of teaching, but also the direct participants in teaching and the main body of learning and development. Teachers' teaching is important, but for students, after all, it is an external cause, which can only work through internal factors. The knowledge and skills taught by teachers and the ideological influence exerted by them require students to observe, think, understand, practice and consciously apply, so that self-cultivation can be transformed into their own skills and morality. In the teaching process, it is particularly important to give full play to students' enthusiasm. Students' learning initiative and enthusiasm affect their curiosity and self-confidence, and determine their learning effect and physical and mental development level. Students' learning is a factor that can't be ignored in teaching. Without students' subjective efforts, no matter how well the teacher teaches, students will turn a blind eye, listen and turn a deaf ear, and ultimately fail to achieve the teaching purpose.
In the whole teaching process, teachers and students promote each other. Teachers will always play a leading role in teaching purposes, directions, contents and methods. However, judging from students' cognitive activities, whether they have conscious learning desire and positive learning action is the decisive factor. In the teaching process, only by organically combining the leading role of teachers with the main role of students can teaching and learning complement each other and promote each other.
