解决数学问题时需要运用多种数学思想,其中人们大多数习惯通过正向的思维方式解决问题,然而有些问题通过正向思维不能很好地得到解决或者解答受阻时,巧妙运用逆向思维来分析问题就显得尤为重要,很多受阻问题迎刃而解。但是,逆向思维的形成不是单靠一两节课就能够说明白的,它需要我们教育工作者长期坚持不懈的努力。为了取得良好的教学实效,教师将这一思维融入习题中,将会是一个非常 To solve mathematical problems, we need to apply a variety of mathematical ideas, in which most people are used to solving problems through positive thinking. However, some problems are subtly solved by positive thinking or are inadvertently analyzed by reverse thinking It is particularly important, many blocked problems solved. However, the formation of reverse thinking can not be explained in just one or two lessons. It requires the persistent and unrelenting efforts of our educators. In order to achieve good teaching effectiveness, teachers will integrate this thinking into the exercise, it will be a very
