Abstract
According to the survey of the employment status of Chinese college students and the results of the parents' questionnaire, the lack of comprehensive ability and practical experience among college graduates has become the most worrying problem for the society and students. However, the traditional education mode pays too much attention to the first class, or separates the first class from the second and third classes, emphasizing their respective independent roles and reducing the comprehensive effect of the three classes. Therefore, it is of great practical significance to explore how to improve students' practical ability, comprehensive ability and innovative spirit through the integration of classroom system.
