Developing network teaching is the inevitable choice of school education in the information age. Education is an industry, and the quality of its products needs social inspection. Without the social environment, there is no quality structure and training mode of talents. Similarly, network teaching is the product of the information age, and our discussion on network teaching must also proceed from the characteristics of the information age.

The characteristics of the information age can be summarized as follows: "knowledge expansion" with a large amount of information; Knowledge update speed is fast; Talent competition is fierce. On the one hand, the rapid update of information needs learners to learn cognition, on the other hand, it needs the society to build a perfect and convenient lifelong education system, so that people can receive education freely and update their knowledge without the limitation of time and space.

Similarly, education needs not only the quality structure of talents, but also scientific content and optimized methods, so that learners can receive education with high quality and high efficiency.

In short, in the information age, on the one hand, the quality structure of educational products, that is, talents, has put forward special requirements. On the other hand, it puts forward higher requirements for education level, education opportunities and convenience.

Secondly, the network is the most effective information acquisition tool in the information society. Carrying out network teaching is conducive to cultivating students' ability to obtain, analyze and process information by using the network, thus promoting the cultivation of students' information ability.

Thirdly, developing online distance education is the most effective way to popularize education and lifelong education in the information age.

Finally, the huge network information resources, superior multimedia functions and multi-directional interactive functions make it possible to improve teaching quality and efficiency. We are facing an era of continuous improvement of network services. We are facing an era of highly informationized education. Developing network teaching is the need of the times and the inevitable choice of school teaching.
