作为一名数学教师,根据这些年的教学经验我一直在关注这样一个问题:对于某个题学生理解了、会做了,他们不是快速的把它做出来而是用大量的时间去把它完成,甚至简单的问题复杂化的把它解答出来,我个人认为该一秒做出的绝不浪费两秒,尤其在考试过程中更应该如此,那么怎样在平时去锻炼学生的做题速度和准确率呢?下面就这个问题浅谈一下我个人的见解。我认为学生解题速度慢的主要原因有两个:一是双基较差,二是解题策略不当。在这两个原因中,第二个原因的影响更大些。对此,我总结出如何又快又准的答题有如下几种途径:一、利用定义简捷解题。数学中的定理、法
As a math teacher, I have been focusing on the teaching experience of these years for such a question: for a certain subject students understand, they will do it, they do not do it quickly, but spend a lot of time to finish it , Or even complicated problems to answer it out, I personally think that the second to make a waste of not two seconds, especially in the examination process should be so, then how to exercise in the usual students do speed and accuracy Rate? Here’s a brief talk about my personal opinion on this issue. I think there are two main reasons why students solve problems slowly: First, double base is poor; second, improper problem solving strategies. For both reasons, the second is more influential. In this regard, I summarize how fast and accurate answer the following ways: First, the use of simple definition of problem-solving. Theorem in mathematics, law
