(1) I think this activity can be explained by behaviorism and cognitive learning theory. The experimental results show that active learning based on network can improve students' autonomy, independence and creativity, and greatly promote students' learning motivation and interest. In addition, students also think that using the internet to communicate is simple and fast, which can eliminate the influence of human factors such as status, ability and competition, and it is their favorite way of communication.

(2) Explain students' activities with constructivism theory and its enlightenment to our school education: First, constructivism holds that:

1. Knowledge is not a purely objective reflection of reality, and any symbol system that transmits knowledge is not an absolutely true representation. It is only an explanation, hypothesis or hypothesis of the objective world, and it is his psychological experience of the objective world. This is not the final answer to the question. It will change, sublimate and rewrite with the deepening of people's understanding, and new explanations and assumptions will appear constantly. Knowledge cannot absolutely and accurately summarize the laws of nature and society, and provide solutions applicable to any activities or problems. When solving specific problems, we need to re-process and re-create the original knowledge according to the situation of specific problems.

2. Knowledge cannot exist outside the individual in the form of entity. Although knowledge has been given a certain external form through language and has been generally recognized, it does not mean that learners have the same understanding of this knowledge. Real understanding can only be constructed by learners themselves based on their own experience and background, and depends on the learning process in specific situations. Otherwise, it is not called understanding, but passive plagiarism learning. The so-called "knowledge" mastered by students is just some abstract and meaningless symbols.

3. Textbook knowledge is only a reliable explanation or assumption of a phenomenon, not an "absolute reference" to explain the real world. Scientific knowledge at a certain stage of social development certainly contains truth, but it does not represent the ultimate answer. With the development of society, there will be a more real explanation.

4. Any knowledge is meaningless and authoritative to the individual before it is accepted by the individual. Therefore, teaching should not teach students knowledge as a predetermined thing, nor should we take our understanding of knowledge as a reason for students to accept it, and use social authority to subdue students. Students' acceptance of knowledge can only be constructed by themselves, and the rationality of knowledge should be analyzed and judged with their own experience as the background. In the process of learning, students should not only understand new knowledge, but also analyze, test and criticize it.

The fundamental point of the future education model is student-centered. In the whole teaching process, teachers play the role of organizer, director, helper and promoter, make full use of various elements of learning environment, and give full play to students' initiative, enthusiasm and initiative, so that students can have a deeper understanding of the nature and law of things reflected in the learning content and the internal relationship between this thing and other things. In fact, people have long realized this, but in the past, we lacked the ideal environment to realize this teaching mode, and we didn't have so much manpower and material resources to realize this teaching environment that can cultivate creativity. With the rapid development of science and technology, Internet and multimedia computers have gradually become a part of daily life. The excellent characteristics of Internet and multimedia technology make them the best choice to realize this teaching environment. It can not only save a lot of manpower and material resources, but also realize some advantages that the artificial environment does not have. We say that the Internet is a necessary condition for the reform of today's teaching mode, and it is based on this that the deep combination of the Internet and education should also be based on this. At present, in our country, it is impossible to completely popularize this teaching mode in view of the realistic conditions, but we cannot turn a blind eye to this changing trend. We should carry out research on new teaching modes in some places where conditions permit, and constantly accumulate experience and lessons, so as to be less confused and less painful in the deep-seated reform of the education system in the future. We know that in the "teacher-centered" teaching system, students' initiative and enthusiasm are often limited to a certain extent, and it is difficult to reflect students' cognitive role. In class, we can partially offset this shortcoming through teacher-student interaction. In Internet-based distance education, students have full initiative and can give full play to their creativity, but if students lack initiative and enthusiasm, the teaching effect will be extremely low. Therefore, we must make an in-depth study of this future teaching mode and its teaching effect. We should publicize its effective and positive effects, but we should make preparations in advance to minimize its negative and negative effects on education. Otherwise, the abuse of the Internet may lead to the investment of a lot of money and manpower, but it will not achieve the expected results, which will have a significant negative impact on education in China.

Therefore, it is rich to explain students' activities with constructivism theory and its enlightenment to our school education. The key lies in how educators grasp its connotation.
