Through classroom observation, questionnaire survey and discussion with student representatives, we find that college students' classroom problem behaviors are universal and diverse. The order of occurrence is: sleeping, deserting, reading extracurricular books, chatting, playing mobile phones, doing other homework, listening to music, eating snacks, being late, leaving early and so on. There are gender differences in classroom problem behavior. Boys are more obvious in explicit behavior than girls, and girls are more obvious in implicit behavior. The survey results show that liberal arts students are more likely to have problem behaviors than science students. The truancy rate of liberal arts students in professional courses is 14%, and that of non-professional courses is 25%; Science students are 7% and 2 1% respectively. There are more classroom problem behaviors in public classes than in professional classes, which shows that the attendance rate of public classes is lower than that of professional classes. It is also a public course, and the problem behavior in English class is lower than that in politics class. Because English is CET-4 and CET-6, students are more careful in class. Political lessons are theoretical and boring. Whether you understand it or not, you only need to strengthen your memory before the exam to get credit. Therefore, the classroom problem behavior of political class is more prominent. From the age point of view, the older you are, the more serious the classroom problem behavior is. Students who are about to graduate face employment and postgraduate entrance examination, and many courses are not attended at all, or even absent for a long time.

The adverse effects of college students' classroom problem behavior can be summarized into three aspects: first, it affects the individual learning effect of students and is extremely harmful to their physical and mental health; Secondly, these classroom problem behaviors make the classroom atmosphere depressed, dull and lack of vitality, which greatly affects the classroom teaching effect; Third, it has dampened the enthusiasm of teachers, leading to disharmony between teachers and students, and even open conflict.

Second, the causes of college students' classroom problem behavior analysis

In view of the various manifestations of college students' classroom problem behaviors and their adverse effects, it is necessary for us to analyze the causes of these classroom problem behaviors.

1. Utilitarianism of social atmosphere and popularization of network resources

With the rapid economic development and social transformation in China, great changes have taken place in the original system, concept and social structure, coupled with the infiltration of western pragmatism and individualism. In this context, social development is becoming more and more utilitarian. As social individuals, college students are inevitably affected. Their value goals have shifted from focusing on ideals to paying more attention to reality, from focusing on overall interests to paying more attention to personal interests, and from focusing on long-term interests to paying more attention to immediate interests. For example, students show more classroom problem behaviors in specialized courses and practical courses such as' foreign languages and computers' than in basic courses. With the rapid development of network, school education has new vitality, but it also brings huge problems and challenges. The wide application of the Internet in various fields of society has brought about the multi-source, randomness and accessibility of information, which makes it easy for students to obtain a large amount of information, leading to the decline of the authority of the classroom, and students are prone to classroom problem behaviors. Due to the negative influence of false information, unhealthy content, online games and hostile culture, some students can't resist the temptation and spend a lot of time and energy on the Internet, which is manifested in classroom problems such as inattention, sleeping and being in a daze.
