In view of the problem that parents and teachers cannot share educational information quickly and effectively in the busy schedule, as well as the low interactivity of current home-school information and the difficulty of synchronous real-time management of students in school, a common information exchange and student management system for teachers, students and parents is designed. Relying on WeChat applets, we have set up teachers, students and parents, using visual information organization to establish integrated communication channels. The aim is to use Internet technology to share home-school information, realize home-school interconnection, and achieve the ultimate goal of common education.
