The development of science and technology always permeates people's work, life and study at a speed beyond people's imagination. With the popularization of GPRS and other wireless network technologies, it is not a distant thing for students to have wireless Internet terminals. Students can sit in classrooms, libraries and even study online by the pond in the center of the campus. However, in the eyes of some teachers, the rise of this new technology is a challenge to their educational activities, because students' attention has shifted from teachers to devices such as laptops, PDA and VoIP.

In the traditional class, there are always some students who don't pay attention to the lecture. The popularity of notebooks and mobile phones has increased the proportion of these students, and these devices can do whatever they want after networking. In the past, students could play cards or mine-sweeping games with their notebooks. Now they have millions of games to choose from, and they can watch movies online.

Ivan Aires, a professor at Yale Law School in the United States, pointed out that this is harmful to students, and it is addictive. If one student surf the Internet in class, it will have a negative impact on other students' interest in learning. For teachers, if the first quarter of the students are playing computer, they will naturally not have much enthusiasm for teaching. Professor Ivan later decided to ban students from playing computer in his class, which was opposed by students. Finally, he had to ask the students playing computer to sit at the end of the classroom so as not to affect other students.
