不久前,笔者为华东师大《数学教学》杂志写了一篇文章,题为《从一道高考题的错证看数学教师要学生数理逻辑》。目的是想让广大的数学老师知道,为了搞好教学工作,要学一点数理逻辑。其实,普通的逻辑知识也不是每一位数学老师都掌握得很好的。本文就想剖析数学教师中几种流行的,但是是不妥当的,然而,又并未意识到是不妥当的几种说法来说明学点逻辑的必要性。 Not long ago, the author wrote an article for the “Mathematics Teaching” magazine of East China Normal University, titled “Looking at mathematics teachers’ mathematics logic from the wrong test of a college entrance examination question”. The purpose is to let the majority of mathematics teachers know that in order to do a good job of teaching, we must learn a bit of mathematical logic. In fact, ordinary logic knowledge is not every master of mathematics is very good. This article tries to dissect several of the popular math teachers, but it is not appropriate. However, it does not realize that it is inappropriate to use several arguments to illustrate the logic of learning.
