1. The quality of college students has declined due to their own reasons. With the popularization of higher education, most colleges and universities are facing the problem of the decline in the quality of students. Colleges and universities have lowered the threshold for students, especially the decline of their quality. A considerable number of students belong to the middle and lower classes in junior high school and high school, especially those with low test scores. Most of them have no awareness of learning and often play or skip classes.

2. Due to the reasons of the school, the majors and courses in colleges and universities are not reasonable enough. At present, the structure, system and content of some courses in colleges and universities are far behind the needs of the situation, lacking certain scientificity and rationality, which makes students have to learn advanced theoretical knowledge by themselves to adapt to social competition;

3, management reasons, inspection is not enough. After the expansion of enrollment in many colleges and universities, the number of students is increasing, and the number of administrators is relatively small, so management can't keep up with the pace of expansion. It is not enough to rely on student cadres or classroom teachers to call the roll occasionally. School administrators only check the attendance of teachers and pay little attention to the attendance of students.
