衣服有了破洞舍不得扔弃,需要缝缝补补,计算机程序出现漏洞,又不愿改弦更张,则需要打补丁进行升级,而数学解题过程中,稍不注意也会出现一些漏洞,需要我们提高警惕下面通过几个具体的例子对学生在数学解题过程中出现的漏洞进行探讨.一、解方程时出现的增根和失根漏洞方程思想是中学生必须掌握的重要思想,解方程的方法也是学生必须熟练掌握的基本技能,它们在数学学习中占据极其重要的地位然而不少学生在解方程的过程中由于没有考虑未知数的隐含条件,未能进行同解变形,从而出现了增根和失根的情况.
Clothes with broken holes could not be discarded, the need for stitching make up, loopholes in the computer program, but also do not want to change the string more Zhang, you need to patch to upgrade, and mathematical problem solving process, there will be some attention to some loopholes, we need to improve Vigilance following through several specific examples of students in the process of mathematical problems loopholes to explore.First, the solution of equations appear when the root of the root cause of the root-and-hole vulnerability is the important idea of high school students to master the method of solving equations But also students must master the basic skills, they occupy an extremely important position in mathematics learning However, many students in the process of solving equations because they did not consider the implicit conditions of the unknown, the same solution can not be deformed, resulting in increased Roots and lost roots.
