To do a good job in moral education for teenagers, we should start with the trinity education system of school, family and society to form a moral education network for teenagers. Nowadays, teenagers have complex knowledge structure, outstanding personality and strong independence. Especially with the rapid development of globalization and networking in today's society, they are eager for a free and colorful study life, which makes moral education in schools more difficult. The key to solve this problem is not to increase the number of courses and class hours, but how to reform the educational content and improve the educational methods, so that they can be linked with social reality and close to students' lives. Moral education is not only the responsibility of ideological and moral lessons, but also the responsibility of all subjects' teaching and activities, and it is also the common responsibility of family and society.

Improve the network management mechanism

At present, the network has been integrated into the real society and has more and more influence. Teenagers, as the most active whole in society, have become the earliest contact group, the deepest and widest group influenced by the network. It is true that the information and achievements of science, technology, culture and art collected by the Internet help young people broaden their horizons and increase their knowledge. However, behind the prosperity of the Internet, there are also a lot of unhealthy things, some of which are even vulgar in language and low in style. If not properly guided, it will have a negative impact on the spiritual and moral world of teenagers. Relevant departments should establish and improve the management mechanism of unblocking at the same time, make full use of network means, improve the status of online education, enrich the content suitable for teenagers to browse, set up internet cafes for teenagers, vigorously advocate the "convention on network civilization", organize and carry out healthy and beneficial activities such as "healthy internet surfing, online video classes, and web page design competitions" to attract teenagers to websites that spread advanced culture and let them surf the Internet healthily.
