在数学教学中 ,根据学生的认知规律 ,合理有效地选用一组数学问题组织教学 ,并且在这些问题的解决过程中 ,除了解决个别数学问题外 ,还须通过几个问题的前后联系以及解决这些问题的方法的变化 ,形成一种更高层次的思维方法 ,以达到对问题本质的了解、问题难点的突破、问题规律 In mathematics teaching, according to the students’ cognitive laws, a group of mathematics problems are used to organize teaching in a reasonable and effective manner. In addition to solving individual mathematical problems, it is also necessary to pass through several problems before and after and solve problems in the process of solving these problems. Changes in the methods of these problems have resulted in a higher level of thinking in order to achieve an understanding of the nature of problems, breakthroughs in problems, and problems.
