数学课的设计,由于所教的内容不同,教法往往不同,尤其是发现方法的应用,可以将教法视为发现法.而数学思想的培养,不是一朝一夕的事情,必须时时处处渗透在教学中,我在讲解二元二次方程组解法时,特意设计了一节运用化归法解题的教案.所谓化归法,就是将所要研究的数学问题,进行变 The design of mathematics courses, because of the different teaching content, the teaching methods are often different, especially the application of discovery methods, the teaching method can be regarded as the discovery method. The cultivation of mathematical ideas is not a matter of overnight, must always penetrate the teaching In the course of explaining the solution of the binary quadratic equations, I specifically designed a lesson plan that uses the method of transformation to solve problems. The so-called transformation method is to change the mathematical problems to be studied.
