According to a survey, middle school students nowadays are less and less interested in learning mathematics, and many students even hate mathematics. The main reason is that teaching ideas and concepts are outdated and teaching methods and means are backward. In the teaching process, teachers overemphasize "delicacy" for fear of eating "raw rice" and always demand "one step at a time". The result of this is obviously that the classroom capacity is small, the teaching progress is slow, and teachers often sweat profusely. The natural efficiency is very low and the quality is not high. With the development of quality education and the reform of education and teaching in full swing, different people have different ways to change the above situation. Combined with my own practice in the past three years, I think that using the idea of "* X" experiment to guide senior high school mathematics teaching will definitely improve classroom efficiency and teaching quality. "GX" experiment conforms to the laws of pedagogy and psychology. Its guiding ideology-"32-character formula" is an innovation of China's mathematics education theory. In the spirit of "paying equal attention to quality and benefit" and from the new perspective of "maximizing time benefit", the comprehensive reform experiment of educational concept, teaching materials and teaching methods was organized. This experiment is mainly carried out in junior high school, but it is still applicable to senior high school. There are ready-made experimental textbooks in junior high school, and the operation is simple. There is no experimental teaching material in high school, and the operation process is just put into practice. ..
