Our school constructs a teaching and research ecosystem of "the young and the experienced complement each other and pass on knowledge and skills". Weekly collective lesson preparation gathers subject wisdom. Report classes of young teachers show their new-edge and sharpness. Exchange classes of backbone teachers spark thinking. Demonstration classes of renowned teachers lead the professional direction. We strictly grasp the teaching routine of four inspections in each semester, forming a rigorous closed loop of "promoting improvement through inspection and promoting excellence through evaluation" and consolidating the lifeline of teaching quality. We promote morning reading classes that immerse students in the context, self-study classes that calm the mind and stimulate thinking, caring classes that are strict yet loving, and interactive classes that focus on refined explanations and practice, stimulating students' in-depth thinking and promoting the resonance of teachers' and students' thinking.
