数形结合思想把抽象的数和直观的几何图形结合起来,使得很多的复杂的数量问题转化为直观的几何图形问题,便于学生理解也利于教师讲解。一、数形结合思想含义的理解及适用范围高中数学所研究的数比较抽象难懂,对学生的抽象思维能力要求较高,而形虽然较直观,但对学生的空间思维能力也要求较高。在实际生活中数和形是密不可分的,而 The combination of abstract number and intuitive geometric figure makes the combination of abstract numbers and intuitive geometric figures make a lot of complicated quantity problems into intuitive geometric figure problems, which is convenient for students to understand and teachers to explain. First, the number of ideological understanding of the meaning and scope of understanding The number of high school mathematics study more abstract and difficult to understand, the students’ ability to abstract thinking is higher, while the shape is more intuitive, but also requires a higher spatial thinking ability of students . Number and shape are inextricably linked in real life, however
