Mobile phone is a communication tool, which can facilitate communication between people. It has become a popular new information carrier, even surpassing newspapers and other carriers in some aspects, and has become a prominent fourth media. Nowadays, more and more people have regarded mobile phones as a necessity. According to the statistics of Xinhuanet, by the end of August 2008, the number of mobile phone users in China exceeded 5150,000, among which college students accounted for a considerable share. When mobile phones become a necessity for college students, I don't deny that as a new information carrier in the new era, mobile phones have indeed brought changes in the history of information dissemination to people, but they have also brought great negative effects to contemporary college students to varying degrees. Online handwriting is convenient and fast. At the same time, many college students play online until three or four in the morning, and then continue to skip classes and indulge in the online world the next day, resulting in a lot of homework and failing the exam. Under the trend of comparison, college students, a pure consumer group without income, compete for high-consumption and high-price mobile phone services. Nowadays, mobile phone consumption is becoming a fashion day by day, and college students have become a force to be reckoned with. There are also college students' thumbs, that is, a huge group that communicates through SMS. Because short messages are cheap, quick, brief, interactive and hidden, many college students regard short messages as a habit, and more importantly, a kind of life dependence. "Short message culture" should be said to be a progressive performance in the information age, because it not only brings us the gospel of a new function, but also paves the way for the successive generation of graphic information, the development of mobile phone internet access function and the functional extension of smart phones and 3G mobile phones. However, it cannot be ignored that with the proliferation of college students' short messages, the proliferation of this culture has also become a headache for teachers and parents, because this culture has begun to grow into a negative factor for the healthy growth of contemporary college students in tangible and intangible ways. I usually know that there are no text messages and no incoming calls, and I will look out my mobile phone from time to time; When the mobile phone is not around, I am upset; If the mobile phone doesn't ring for a while, it will feel uncomfortable; When the mobile phone can't dial, or can't receive the signal, it is anxiety. There are many college students in all the above situations! It is this "thumb" culture that encourages college students to rely on mobile phones! It should be said that the large-scale rise of mobile phones among students is the progress of the times, but while mobile phones have caused many negative effects on contemporary college students, should our relevant educators take some measures to avoid the negative effects brought by college students using mobile phones?
