The "Smart Primary and Secondary Schools" APP on the mobile terminal of the national smart education platform for primary and secondary schools is officially launched, which will provide a more convenient way for carrying out teaching activities, autonomous learning, home-school cooperation and mutual assistance and exchange anytime and anywhere. Like websites, APP has six kinds of resources, including special education, course teaching, after-school service, teacher training, family education and practical experience in teaching reform. At the same time, teachers, students and parents can register and log in according to different user identities, and have different access rights accordingly. "Smart primary and secondary schools" have also added the functions of resource operation and interaction. All video resources can be played on screen, and course teaching resources can be cached and watched offline. It is particularly worth mentioning that if you encounter problems in the learning process, you can also click "Ask" to ask questions and communicate with the class teacher. At the same time, "smart primary and secondary schools" also provide support for teachers to carry out organized education and teaching activities, and provide home-school coordination functions for teachers and parents.
