逆向思维也叫求异思维,是与正向思维相对并从原问题相反方向着手的一种思维方式,有助于复杂问题的简单化从而提高办事效率。逆向思维是数学思维的重要原则,高中数学是一门逻辑性很强的学科,学生学习时需要突破传统思维方式。因此高中数学教师应在数学教学过程中充分认识逆向思维的重要作用,同时,结合教材内容注重高中数学逆向思维的应用,提高学生逆向思维水平进而增强 Reverse thinking is also called thinking differently. It is a way of thinking that opposes positive thinking and starts from the opposite direction of the original. It helps to simplify complicated problems and improve work efficiency. Reverse thinking is an important principle of mathematical thinking, high school mathematics is a highly logical discipline, students need to break through the traditional way of thinking. Therefore, senior high school mathematics teachers should fully understand the important role of reverse thinking in the process of mathematics teaching. At the same time, we should pay more attention to the application of reverse thinking in high school mathematics in order to improve the level of students’ backward thinking
