研究解题方法,总结解题规律,已引起广大师生的重视。但是我们应该提醒和强调的是:验算也是解题过程中的一个重要环节。目前,不少学生做错了题,往往还三遍两遍地检查不出自己解题中的错误,其原因是由于他们只知道重做一遍,或重看一遍,而不是运用数学知识和方法从不同的角度来进行检验。所以经常听到一些同学唉声叹气地说:我把某某题都做了三遍,怎么还是错了!事实说明,这种重做一遍的方法不是检验解答正确性的好方法,容易重踏覆辙。本文介绍几种常用的检验方法,供读者参考。一、查解题过程解题的过程,就是以题设条件和已学过的公式、定理、法则等为依据进行一系列的推演和论证的过程。所以检查解法正确与否的一个最基本的方法,就是一步一步地检查解题过程 Studying problem-solving methods and summing up the law of problem solving have aroused the attention of teachers and students. However, we should remind and emphasize that checking is also an important part of the problem solving process. At present, many students make mistakes and often fail to check their mistakes three times in a row. This is because they only know to redo or re-read, instead of using mathematical knowledge and methods. Different angles to test. Therefore, I often hear some students sigh and say, “I’ve made three or more iterations of my questions, and I’m still wrong! The facts show that this method of redoing is not a good way to check the correctness of answers, and it is easy to relapse. This article introduces several common test methods for readers’ reference. First, the problem-solving process of the problem-solving process is to carry out a series of deduction and argumentation processes based on the conditions of the questions and the formulas, theorems and rules that have been studied. So one of the most basic ways to check whether the solution is correct or not is to check the process of the solution step by step.
