(A) the teacher is the giver of knowledge.

In the traditional teaching mode, teachers' activities focus on imparting knowledge, and teachers are mainly concerned with the capacity of knowledge, the solution of key knowledge and difficult knowledge, and whether students master knowledge.

(2) Teachers are the designers, organizers and implementers of educational activities.

Whether it is traditional teaching or modern teaching, only by adhering to this point can teachers play a leading role and education and teaching activities develop healthily. In this role, teachers should give full play to their leading role, show their teaching style and educational ideas on the premise of respecting students' individuality and meeting students' needs, so as to make teaching activities vivid but not chaotic, orderly but not rigid, pay attention to teaching routines and be creative.

Teachers are the guides of students' autonomous learning and ideological development.

In teaching, the function and role of teachers' knowledge transmission is gradually weakening. More and more teachers have changed from imparting knowledge to guiding students' autonomous learning through various teaching activities, and assumed the responsibility of guiding and helping students to select, manage, organize and process knowledge. In the development of students' ideological concepts and moral will, teachers change from norms to guidance, guiding and helping students to establish a correct outlook on life and cultivate moral will, rather than one-sided "education". As promoters and instructors, teachers need to provide appropriate background knowledge, prompting the methods and sources of obtaining further knowledge and information; Give students psychological support, create a good learning atmosphere, and adopt various appropriate ways to give students spiritual encouragement, so that students can think more actively and explore more enthusiastically; Pay attention to cultivating students' self-discipline ability; Before students may encounter problems, make forward-looking predictions and make early adjustments to avoid students taking detours; When students feel confused or encounter problems that are difficult to solve, they should be given appropriate guidance and explanations to help them get rid of confusion and make reasonable choices.

(D) Teachers are an organic combination of educators and learners.

The role of teachers as educators is one of the decisive factors that affect the efficiency and effectiveness of teaching activities. As educators, teachers should show profound knowledge accumulation, ability to find, analyze and solve problems, good psychological quality, rich emotional experience and strong organizational control ability in teaching activities, and guide and help students to carry out effective learning activities by using reasonable teaching strategies and educational technologies under the guidance of advanced educational concepts.

At the same time, teachers as learners should do: (1) Teachers should update their knowledge structure and expand their knowledge space through continuous learning. (2) As learners, teachers should master the general methods and related knowledge of scientific research and improve their scientific research quality; (3) Students are constantly flowing and changing. Teachers should constantly strengthen communication and exchanges with students, understand students, learn and deepen their understanding of students' commonness and individuality in the interaction between teachers and students, and teach students in accordance with their aptitude.
