There are many reasons for these problems. From the perspective of education itself, there are some deep-seated reasons worth considering. ? The goal of some schools is unclear, and the concept of running a school can't meet the social demand for talent training? In the past decade, the enrollment scale of colleges and universities has been expanding, the number of colleges and universities has been increasing, and the quality is mixed. Regardless of their own conditions, limitations of school-running level and original school-running characteristics, many schools blindly pursue greatness and put forward the goal of building a research-oriented and comprehensive university. Even some municipal universities have put forward the goal of running a world-class university, and the scale of running a school has been expanding.

In terms of teaching ideas, some schools can't fully consider the enrollment conditions and social employment needs, blindly implement general education, and greatly weaken the cultivation of students' professional knowledge and practical operation skills, resulting in students' lack of professional skills and application ability, students' theoretical basic level and research ability are not recognized by the society, and students' employment ability is seriously out of touch with social needs. ?

The policy mechanism is not in place, the central position of teaching in school work has not been really implemented, and teachers' teaching enthusiasm is not high? At present, in the evaluation mechanism of colleges and universities in China, whether it is the overall evaluation of the school by the Ministry of Education or government departments at all levels, or the various rankings and evaluations of colleges and universities by the society, the scientific research index of the school is the main measure, which leads to the obvious phenomenon of attaching importance to scientific research and neglecting teaching in the policy mechanism of the school. Therefore, teachers' teaching enthusiasm is seriously insufficient. In addition, there are few senior professors and academic leaders engaged in undergraduate teaching, which is a common phenomenon in some universities, especially key universities, and also affects the quality of undergraduate teaching to a great extent.

The monitoring and guarantee system of teaching quality is not perfect, and the problems existing in teaching work have not been solved for a long time? Since the beginning of 2 1 century, the evaluation of undergraduate teaching level in colleges and universities implemented by the Ministry of Education has played a positive role in improving the teaching quality in colleges and universities.
