In the past year, the "double reduction" policy has sounded the theme of deepening the reform of basic education in China with a magnificent practical situation. Over the past year, the results of the "double reduction" have been gratifying, and the pattern of school education has changed, especially for students, who have got rid of the heavy burden of schoolwork and lived a "good life" of learning. The core function of school education is really "strong". The "double reduction" puts forward three core tasks for the school: improving the quality of classroom teaching, improving the quality of after-school homework, and improving the level of after-school service. Among them, classroom teaching is the main channel for the implementation of national curriculum, and it is also the aorta for the healthy growth of students; Homework is a natural and inevitable derivation of classroom teaching and a necessary process to consolidate and develop teaching objectives; After class service is a school-based and selective course for students after the school completes the national curriculum, which also includes the re strengthening of classroom teaching and the re guidance of after-school homework. Obviously, these three core tasks are a conceptual framework of "big curriculum". Before the "double reduction", it seems that we have never integrated classroom teaching, after-school homework and after-school services, which is also the functional "bonus" brought by the "double reduction" to the school. In fact, the implementation of the school's overall curriculum system composed of three core tasks and the deepening of "double reduction" have made the core function of school education really "strong". With the implementation of the "double reduction" policy, the most prominent pattern change in school education is that the political position of comprehensively implementing the party's education policy has become firmer, the school mission of comprehensively deepening the implementation of the fundamental task of Building Morality and cultivating people has become clearer, and the work theme of improving the quality of education and teaching has become more solid. Therefore, we really feel that the education ecosystem of basic education is becoming healthier, the main position role of school education is increasingly strengthened, the responsibility of teachers' education is fully reflected, and the kinetic energy potential of students' independent development is fully released. A large number of analytical data obtained through the investigation of the effectiveness of "double reduction" - such as students' satisfaction with the school's meeting their own development needs, students' recognition of the significance of classroom teaching, students' efficiency in completing homework in school, and the proportion of students who voluntarily participate in after-school services, all convincingly support our basic judgment: "double reduction", Let thousands of students' learning enthusiasm and learning opportunities return to the campus with an irreversible trend. It provides students with high-quality learning and life. Classroom teaching, after-school homework and after-school services constitute an integral chain of students' learning and life in school. Teachers' educational and teaching concepts directly affect the implementation of the three core tasks and directly determine the quality of students' learning. Around the three core tasks, what kind of classroom teaching, after-school homework and after-school service can promote students' learning and growth? How to deepen the reform of classroom teaching? How to design high-quality operations and manage them scientifically? How to design high-quality after-school services and arrange them scientifically? This is the basic and fundamental problem of implementing the three core tasks. Since the implementation of the "double reduction", schools in all regions have been trying to focus on these issues. Taking 102 "typical cases of load reduction and quality improvement in schools" promoted in five batches of the education part as samples, it is not difficult to find through analysis that "double reduction" has strongly inspired the educational and teaching wisdom of the majority of principals and teachers, and those scientific and solid practical exploration of classroom teaching, after-school homework and after-school service has become a beautiful landscape of basic education reform. Here only take the classroom teaching reform as an example. The new demands of "double reduction" on classroom teaching and the new requirements of new curriculum standards on classroom teaching converge into a new value concept: Deepening the reform of classroom teaching should highlight the importance of educating people, and should take morality and cultivating people as the soul. As a result, many teachers are no longer superstitious about such logic - only through a large number of exercises in classroom teaching can students get higher scores; Therefore, it is necessary to pursue the goal of "being clear in the classroom" and realize the "efficient classroom" of "no tail left in the goal and no debt in the content" with high-capacity and fast-paced intensive training. Teachers should consciously practice such teaching: we should deeply excavate the unique cultural connotation of the subject curriculum; To protect each student's self-confidence and unique personality; We should fully stimulate and inspire students' curiosity, imagination and creative thinking; It is necessary to actively explore the course content of the connection between learning stages, the integration of disciplines and the connection with life; We should carefully design the teaching structure with problem-solving as the main line, and so on. Over the past year, the basic education reform with the theme of "double reduction" has injected strong impetus and vitality into school education. With the further promotion of "double reduction", look forward to the future, and the future is foreseeable! (outlook new era)
