There have been many discussions about how to improve and evaluate the teaching quality and level of teachers. In view of the new situation, new situation and new requirements of education and teaching reform faced by colleges and universities, we believe that the level of scientific research work of college teachers is really related to the development of teachers, but to be a famous teacher, the main evaluation index is to be able to carry out first-class teaching work, cultivate first-class talents and become a teaching master to promote the healthy and stable development of higher education. If the relationship between teaching and scientific research is not properly handled in running colleges and universities, if teaching and educating people and teaching by example cannot become the moral norms of college teachers, and if teachers' teaching level cannot be continuously improved, not only will teachers lose their platform to settle down, but creating first-class higher education and cultivating first-class talents will also become empty slogans, which requires colleges and universities to pay close attention to in the process of reform and development.
Renewing teaching concepts and improving their own quality is an important basis for teachers to do a good job in teaching.
Teachers shoulder the glorious mission of cultivating a large number of talents for the great rejuvenation of the Chinese nation. This requires teachers to always keep the cultivation of first-class talents in mind, consciously improve the quality, ability and level of teaching and educating people, and do not disgrace their mission, mission and public. The apparent role of teachers in teaching is to transfer knowledge, and its purpose is to make students master the knowledge points, thinking methods and learning training of teaching content to the greatest extent, which is the basic level to be realized in the teaching process. The high level of teachers' teaching work is to guide students to establish a scientific way of thinking, research methods and broaden their horizons through teaching activities, to cultivate students' sense of social responsibility for serving the country and the people, to cultivate students' innovative spirit of exploring and practical ability of solving problems, and to develop students' innovative consciousness, innovative potential and innovative ability. Therefore, teachers' teaching work can not only impart knowledge, but also stimulate students' interest in learning and the spirit of exploring scientific mysteries.
Teaching practice has proved that in order to continuously stimulate students' interest in learning, it is necessary to establish a close interactive relationship between teachers and students, which is the basic point for teachers to successfully organize teaching. In other words, only when teachers coordinate teaching and learning can the teaching work achieve good results. Confucius said, "When you are near a village, you should respect it. Filial piety is loyalty. If you can't teach good deeds, persuade them. " To do this, teachers should first consciously improve their comprehensive quality and cultivate their personality charm, including improving their conduct and artistic accomplishment. For example, college physics, which is generally offered in colleges and universities, is an important basic course for college students. Its content involves many basic phenomena, theories and experiments in natural sciences such as mechanics, heat, optics, electromagnetism, vibration and wave, and also includes the basic contents of modern physics such as special relativity and quantum mechanics. The study of this basic course not only enables students to systematically understand and master the basic knowledge, laws, theories and research methods of the movement and evolution of the material world, but also lays an important foundation for students' subsequent professional study and future scientific and technological work. However, in the teaching process of this basic course, it is difficult for teachers to stimulate students' learning vitality if they only impart knowledge. This requires teachers to organize teaching, so that students can feel the wonder and profundity of the physical world from teachers' tireless exploration of physical phenomena, problems, methods and applications, and from teachers' excavation of physical thoughts and historical essence. Then stimulate students' interest in mastering physics knowledge, research methods, practical application and development trend, so that students can realize its extensive application value in learning basic courses, thus cultivating students' innovative consciousness, innovative thinking and innovative ability. Therefore, in order to achieve first-class teaching, teachers need to constantly improve their comprehensive quality and strive to achieve the following aspects: (1) Constantly understand the teaching theory of modern higher education, handle the relationship between scientificity and ideology, knowledge accumulation and intelligent development, teacher-led and student-centered, basic theory and application practice, knowledge systematization and cognition step by step, and constantly update teaching concepts and enrich themselves. (2) Establish teachers' own teaching ideas and form a distinctive teaching style. In other words, teachers should be very clear about their role in teaching. It is often said that the best teaching for teachers is the creation of teachers' wisdom and the performing arts of teachers. Teachers should become students' knowledge base, teachers, instructors and collaborators through teaching activities, so that students can learn knowledge, master methods and accept teachers' training. (3) To create a positive environment for students' learning, teachers should use a variety of evaluation strategies to ponder students' learning psychological activities, diagnose and meet students' various learning needs, so that they can continue to concentrate on learning in class and maintain their learning initiative outside class. In other words, teachers are not simple information people or teachers in front of students, but lively and independent thinkers and actors in front of students.
