In accordance with the new model of information technology construction proposed by the Municipal Education Commission, Changning District follows the principles of “government setting standards and building platforms, enterprises developing products and ensuring maintenance, and schools purchasing services and building resources.” Based on the principles of “IoT connection, data connection, and intelligent connection,” it has achieved “user connection, data connection, application connection, device connection, and message connection” through the construction of “five connections and one screen.” This has resulted in unified authentication for all personnel in the district, unified management of organizations, coordinated integration of various applications at the city, district, and school levels, unified access control for intelligent devices, a unified source of data, and multi-level interconnection, intercommunication, and sharing of information. Relying on the powerful underlying connectivity capabilities of the education digital foundation, Changning District is promoting the digital transformation of education across the entire region, while providing a high-quality soil for personalized construction at each school.
