Abstract: In order to fulfill the fundamental task of cultivating morality and fostering talents, and to integrate ideological and political work into the entire process of education and teaching, it is necessary to mobilize all educational elements, combine the collaborative efforts of multiple educational participants and form an all-involving, whole-process and all-round educational environment. We can integrate resources, improve management, enrich practices, innovate forms, expand our platform, and upgrade the mechanism by promoting experimental practices in school-family-society collaborative education, and combining the four forces organically, with family as the basis, school as the main body, society as the carrier, and student as the object. In this way, once the “four-in-one” collaborative educational system is established, a close educational relationship will be formed, which fully involves families, schools, society and students and a new pattern of school-family-society collaborative education.
