此文是对《数学通报》2 0 0 0年第 10期中一文提出不同意见 ,我们认为这对中学教学中如何掌握推理的严谨性等问题的讨论是有益的 .但我们认为更值得注意的问题是 :1 作为教师应该区别哪些解法是 (逻辑 )不严格 ,哪些是犯逻辑错误 ?2 什么情况下允许学生利用直观作一些不严格的逻辑推理 ?需要注意 ,在任何情况下犯逻辑错误的毛病是不允许的 .3 在课堂教学 ,做习题时怎样掌握严谨性和量力性的关系 ?
This article proposes different opinions on the first article of the 10th issue of the “Medical Bulletin” 2000. We believe that this discussion of how to master the rigorousness of reasoning in the teaching of middle schools is beneficial. However, we believe that the more noteworthy issues are. Yes: 1 As teachers should distinguish which solutions are (logical) are not strict, which are to make logical mistakes? 2 Under what circumstances to allow students to use intuitive to make some unreasonable logical reasoning? Need to pay attention to, in any case make logical mistakes Is not allowed .3 In classroom teaching, how to master rigorous and quantitative relationships when doing exercises?
