The traditional mathematics teaching has restricted students' logical thinking in mathematics. In the past, teachers were regarded as the dominant force in the classroom, while students were seen as the main body. The cramming teaching method forced students to accept knowledge, preventing them from fully understanding and absorbing it. As a result, high school mathematics gradually fell behind. At this point, teachers should change the traditional teaching method, pay attention to students' feelings, cultivate students' logical thinking, get rid of the drawbacks of past teaching, and let students truly explore and master new knowledge, make high school teaching correct and reasonable. This book discards the indoctrination teaching mode and conducts innovative research on improving teaching efficiency. Firstly, it studies the relevant development of high school mathematics teaching, and then proposes effective practical methods and paths to improve the teaching mode from the perspectives of Internet +, divided classroom, ideological and political education in courses, and problem chain teaching, aiming to offer suggestions for the development of high school mathematics teaching.
