The implementation of the "double reduction" policy is an important measure to deepen the reform of quality education and run education to the satisfaction of the people, which puts forward new requirements for the high-quality development of basic education. School homework is reduced, and classroom efficiency is more important; After school training has been reduced, and the responsibility of the school has become more important. In the final analysis, the requirements for teachers are higher. Normal universities should play a leading role, service function and radiation effect, take the initiative to contribute to the continuous promotion of "double reduction" and the high-quality development of basic education. The "double reduction" policy poses new challenges to teachers' professional quality, and normal education needs "two-way strengthening". Colleges and universities should not only empower normal education through teaching research and scientific research, but also consolidate the discipline foundation and train basic education teachers with discipline and professional attainments. We should strive to build a high-level normal student training system with "two-way strengthening" of basic disciplines and educational literacy. In the undergraduate stage, relying on Professional Colleges of various disciplines, focusing on discipline professional quality education, implement the same training scheme for normal and non normal majors, integrate into the relevant curriculum modules of teacher education, and select the best to divert and assess by sections. The College of teacher education is responsible for the teaching of education specialty, and the College of discipline specialty is responsible for the teaching of discipline specialty, so as to realize joint training, joint responsibility and two-way strengthening. While strengthening professional education, we should pay attention to expanding the "main channel" of teachers' ethics to realize the infiltration and advancement of the cultivation of teachers' ethics of normal students. Carry out "moral education through curriculum", promote "moral education through practice", innovate "moral education through reflection", and build strong teachers' morality and style. The "double reduction" work is a complex systematic project. Families, schools, the government and society all have responsibilities. We must coordinate with all parties and promote it as a whole, so as to form a strong joint force. As a normal university, it should give full play to its social service function, promote openness, integration and educational cooperation, build a large platform, carry out large activities, study big problems, expand its influence, and promote the policy consultation and practical research of "double reduction". Taking Nanjing Normal University as an example, the university takes the Yangtze River Delta integration construction as an opportunity to carry out university university cooperation, deepen the strategic cooperation between normal universities and basic education, and strengthen the research, training and service of "new college entrance examination, new curriculum standards and new teaching materials". Give full play to the advantages of comprehensive disciplines and provide non disciplinary courses and interest and specialty education support for primary and secondary schools. Provide pre-school and post-school professional training, training and cooperation for primary and secondary schools. Backbone teachers of basic education and well-known principals are invited to serve as part-time professors and practical tutors. Carry out school local cooperation, cooperate with local governments and competent education departments to hold various basic education schools, build practice and training bases and graduate workstations for normal students, and explore the construction of directional training system for normal students. Implement the "national training plan", support basic education in the central and western regions, and increase training opportunities for rural teachers. Carry out school institute cooperation, establish long-term cooperative relations with local Party schools, academies of Social Sciences, educational research institutions and think tanks, and carry out policy research around the effective implementation of the "double reduction" policy, the high-quality and balanced development of basic education, and the improvement of the quality of normal education. In the digital age, with the accelerated iteration of new technologies such as artificial intelligence, big data and cloud computing, people's ways of production, life and learning are undergoing profound changes, and education is also undergoing digital transformation. While issuing the "double reduction" policy, the state also vigorously promotes the construction of new infrastructure for Education (hereinafter referred to as "new infrastructure for education"), and plans to basically form a new infrastructure system for education with optimized structure, intensive efficiency, safety and reliability by 2025. The "double reduction" policy is intended to guide the establishment of a scientific and objective outlook on education quality, and the focus of the "new infrastructure of education" is to enable education with information technology to achieve the effect of comprehensively improving quality, reducing burden and increasing efficiency, and support the implementation of "double reduction" through personalized and high-quality education. Normal colleges and universities should actively respond to the improvement of teachers' ability and the reform of education and teaching methods in the information environment promoted by artificial intelligence, big data and other technologies, take comprehensive education as the goal, face the talent training needs of the new era and the information society, promote the modernization of teachers with intelligent technology, improve the overall quality and governance ability of teachers, and serve the construction of high-quality education system, Build a new ecology of teacher education that integrates information technology with education and teaching, empowers the management of teachers, and promotes the simultaneous development of five education. We should make full use of digital information technology, provide advanced ideas and intelligent technologies for teachers by creating an "artificial intelligence + intelligent teaching field", create an "artificial intelligence + high-quality resource library" to provide teaching methods and high-quality resources for teachers, build an "artificial intelligence + research community" to provide intelligent diagnosis and accurate evaluation for teachers, innovate teacher training mode and promote teacher education reform.
