The smart teaching system is a new teaching model formed by deep integration with education and teaching based on information technologies such as the Internet of Things, big data, and cloud computing. The implementation of smart classrooms requires teachers to design teaching in the smart education system and connect various devices with the smart education system. Smart classrooms have transformed from traditional teacher-student communication to student-centered teaching methods, laying the foundation for improving student quality and cultivating innovative talents. In recent years, with the introduction of a series of national strategies and policies, such as the "Internet plus" action plan, the process of education informatization has been accelerating, and various schools have built Internet information platforms. To carry out the reform of teaching mode in the context of "Internet plus", we need to fully consider the characteristics and practical significance of the application of Internet technology to education, and at the same time, we need to promote the sharing of various information resources with the aid of educational informatization to promote educational equity; It is necessary to combine the application of information technology in teaching, share resources through teaching platforms, and provide rich and practical network resources to meet teaching needs; Modern information technology can also be used to assist teachers in effective teaching and provide students with diverse choices; Students can also achieve personalized development and meet different needs through information platforms; An effective communication platform can also be provided for schools, teachers, and other relevant personnel through information technology platforms.
