2 1 century is an era of electronic information, so the internet has become the main tool for people to communicate in their study, work and life, and the most people who use the internet are teenagers, most of whom are college students. At the same time, many universities now use information teaching or multimedia teaching in the teaching process, which leads to students' understanding of the network. The online world is a virtual world, which contains a wide range of things, both helpful to college students' study and life and unfavorable to these students. Therefore, in the process of online teaching, the school needs to carry out necessary online ideological and political education for college students to prevent some students from going astray in the learning process.

First of all, the problems existing in college students' use of the Internet in their study and life.

1. College students can't distinguish bad information, so they are misled by bad information and do things harmful to themselves and society.

Network is a double-edged sword for college students' study and life. While bringing convenience to these students, it also brings many adverse effects to their study and life. Among them, its advantage is that it can not only open up and expand our thinking for our study, but also expand our life circle to all parts of the world, which is convenient for us to communicate anytime and anywhere. At the same time, while the network has these advantages, it also exposes corresponding shortcomings. Because college students are curious about all kinds of food, some bad websites or information can't be identified in time, which has caused adverse effects and hindered the healthy growth of college students. These antisocial information and some information related to pornography, gambling and drugs generally exist in the network, which is a great temptation for super curious college students now. Although some students never go to bad websites, some illegal information is mixed with legal information, true information and false information, which makes it difficult for students to distinguish which websites have no illegal information. There are also many rumors or false news in the process of commenting on news or state affairs on the website, which will make some students make wrong decisions in their thoughts and actions. In order to ensure that students can learn healthy and beneficial knowledge through the network, our school or relevant educational institutions must pay enough attention to the ideological and political education of college students on the network, so as to make the network environment healthy and enable students to study and live better on an active and healthy network.

2. Some schools do not have a complete network ideological and political education teaching system for college students.

College students are generally 18 years old or older. The school believes that students have a certain ability to distinguish their own study and life, so there is no corresponding strict system and ideological and political education ideas for their use of the Internet. As a result, students' negative or harmful effects in the network cannot be understood by schools and teachers in time, and schools cannot take timely measures to prevent and guide them correctly. Eventually, students who often surf the Internet are influenced by bad information on the Internet, which seriously hinders the healthy growth of college students in their study and life.

3. The harm of college students' excessive Internet access to physical and mental health.

With the development of electronic information technology, the frequency of college students surfing the Internet is getting higher and higher, and the time is getting longer and longer, which makes these students surf the Internet excessively. Sitting on the internet for a long time reduces students' exercise time and increases the incidence of various diseases, such as spinal problems or poor eyesight caused by long-term internet access. Excessive internet access may also make students dull in thinking, disorder their biological clocks, and have a sense of rejection of external things. After spending too much time online, students will indulge in the virtual world and escape from real life and people's communication. Whether college students are addicted to online games or chatting online, they will lose self-control and willpower and become decadent. Skipping classes often goes to Internet cafes, and some students even violate school discipline in order to surf the Internet. Judging from the consequences of college students' inability to use the Internet correctly for study and life, their physical health, mental health and studies will be greatly affected, and even their future work and family life will be affected. Therefore, in order to purify the network environment and minimize the negative impact and function of the network on college students, we need to carry out formal ideological and political education for college students to lay an ideological foundation for them to surf the Internet healthily and happily in the future.

Second, take corresponding measures to solve the problems of college students in the process of surfing the Internet.

1. Promote the knowledge of healthy surfing the Internet in various ways.

Add some knowledge about healthy internet surfing in the elective courses of the school, or publicize the methods of healthy internet surfing through various knowledge lectures, or infiltrate some common sense of healthy internet surfing by teaching computer professional knowledge.

2. Establish a corresponding network supervision team.

In the use of advanced network technology or software to monitor the school's network information system, it is mainly to monitor some public speeches or postings of students. If you find any remarks or behaviors that violate the national laws or school discipline, you should stop or criticize them in time.

3. Closely combine ideological and political education with mental health education.

The mental health education of college students plays a very important role in their study and growth, and their mental health is a major factor that determines whether they can surf the Internet healthily. If college students can't keep a healthy mind to study and live, even if they have good professional knowledge or skills, they can't serve the motherland and repay the society, and even do behaviors that endanger the society. Therefore, we should combine ideological and political education with college students' mental health education.

Schools should formulate corresponding education systems according to the characteristics of college students' study life, so that college students can create their own world on the road of healthy growth through formal network ideological and political education.

The rapid development of network technology has brought a lot of convenience to people's life and study, but its wide application has also brought challenges to students' ideological and political education, especially for college students who have not yet entered the society. In every stage of students' study and life, parents and teachers need to carry out ideological and political education, but different growth stages correspond to different psychology, viewpoints and practices, so the ideological and political education for students should also change the way and content of ideological and political education with different age groups. In the process of ideological and political education for students, it is necessary to combine the development of society and the requirements of the state for students, not only to keep students' political thoughts positive and healthy, but also to ensure that their thoughts keep pace with the times.
