Abstract:With the widespread use of smartphones, it has become a common phenomenon to play mobile phones in class among college students. In response to this phenomenon, this paper adopts the method of questionnaire survey to investigate 750 students of 3 universities in Nanchong to find out the frequency of using mobile phones in class,the utilization rate in different types of courses, and the attitude towards using mobiles in class, etc. The results show that using mobile phones in class can bring double-sided impacts,and then the author proposes further education strategies for negative impacts.Therefore, it is necessary to guide students from the correct self-attribution,enhancing the initiative to the relaxation of classroom management, taking the necessary teaching reform,and finally strengthening class supervision and management of mobile phones by playing the role of smart phones for teaching.
