Dengzhou Sangao is located in the countryside. Compared with the key senior high schools in the city, Dengzhou Sangao has congenital deficiency, low entrance scores of students and low level of teachers. How to improve the quality of education and teaching under such a disparity in strength? The school leadership team headed by President Li Mingrui put forward the slogan of "survival by quality, development by reform and progress by teaching and research", demanding that quality comes from management, achievement comes from management, constantly strengthening internal management, paying close attention to the management of teaching process, focusing on slimness and implementation. As a result, a series of unique management systems of Dengzhou, Sangao and Sangao have been formed:

—— The collective responsibility system of the class teacher with the class teacher as the core and the collective responsibility system of the subject teachers with the class teacher preparing lessons as the core put forward requirements for the class teacher and the class teacher preparing lessons. Make teaching quality goals, break them down into classes, and put the responsibility on people, so that every class and teacher has goals, pressure and motivation.

-Adhere to the system of collective lesson preparation and improve the quality of lesson preparation. Students often listen to each other, exchange and cooperate, and brainstorm.

-optimize classroom teaching, actively carry out teaching reform, improve classroom teaching efficiency, and require teachers to adopt "learn first, then speak, and practice in class". Every week, a teacher in each subject is assigned to make a well-prepared evaluation in the last class, and all teachers in the undergraduate course listen, learn from each other and improve together, which has achieved good results. School leaders and leaders at all levels follow up the lectures, so that students can get twice the result with half the effort.

-strengthening the work of cultivating excellent students and making up the difference. Most of the outstanding students in Dengzhou Sangao are weak in subjects. For these students, they should have a clear foundation in school, level, class teacher and classroom teacher. Teachers should adopt man-to-man tactics, follow-up training, pay attention to leak detection, guide learning methods and improve learning ability.

-Strengthen the leadership and management of the graduating class. The school has set up a graduating class leading group headed by the principal. Team members implement three guarantees: class guarantee, discipline guarantee, excellent students guarantee, and students guarantee to make up the difference. Bao discipline participates in discipline teaching and research meetings, academic performance analysis meetings and training seminars. Solve the problems in students' life and study in time, and put forward ideas and methods to improve review efficiency. Hold excellent students' symposiums, seminars and analysis meetings for many times, understand and listen to students' opinions on school teaching in time, and understand their changes in thinking, life, study and weak subjects, so that they are always in a state of being cared for, building self-confidence, self-motivated and studying hard.
