目的,学生在解答数学习題时,存在不从习题的实际条件出发、不认真审題的缺点,經常发生由于审错了題而把习题作錯的現象,因而影响作題貭量的提高。这篇文章将要分析这一缺点产生的原因,井提出一些克服缺点的方法。我們想从四个方面来谈这个問題:第一、不从实际出发,不认真审題的原因;第二、必須重视审題工作;第三、作到审題正确是不容易的;第四、必須对学生进行长期訓练,培养他們具有从实际出发,认真审題的习惯。 1.不从实际出发,不认真审题的原因。在作“画函数y=2x~2+4x+6的图象,并求函数的极值”习題时,有些学生沒看清問題的性质,仅凭过去的經驗判
The purpose is that when students answer a number of questions, there are shortcomings that do not start from the actual conditions of the exercises, and do not examine the questions carefully. Frequent mistakes occur because of mistaking the questions, thus affecting the improvement of the number of questions. This article will analyze the causes of this shortcoming and propose some ways to overcome them. We want to talk about this issue in four aspects: first, we must not proceed from reality, and do not examine the reasons for careful examination; second, we must pay attention to the work of examining the subject; third, it is not easy to do the correct review; fourth It is necessary to train students for a long period of time and cultivate their habit of proceeding from reality and examining issues carefully. 1. Do not start from reality, do not seriously examine the reasons. When doing the “Examination of the function y=2x~2+4x+6 image and seeking the extremum of the function” problem, some students did not see the nature of the problem and judged only by past experience.
