近日拜读了梁勤旺的《由一道教参弃选题谈数学解题反思》(《中小学数学》(初中版2015年卜2期))以及祝立新的《解题勿犯条件性错误》(《中小学数学》(初中版2016年卜2期))两篇文章,两位作者分别从“解题后反思的重要性”及“解题时勿犯条件性错误”两个角度谈了自己的看法,本人收获很多,感触颇深,对他们的严谨治学态度也深表钦佩.但两位老师对该题的一些教学策略本人不敢苟同,本文将从该题在实际教学中不同的教学策略导致不同教学效率的角度谈谈自己的看法,望同行指正.
Recently, I read Liang Liangwang’s “Reflections on Mathematical Problems” (“Primary and Secondary Maths” (Junior Secondary School Edition, Issue 2, Issue 2)) from a discourse-based discourse selection and Zhu Liangxin’s “Do not Make Conditional Mistakes” Primary and secondary mathematics “(junior high school version 2016 BU 2 period)) two articles, the two authors respectively from” the importance of reflection after solving “” and “do not make conditional error when solving” " Talking about my own views, I gained a lot, I feel very deep, and I admire their rigorous attitude towards scholarship. But the two teachers did not agree with some teaching strategies on this topic. Different teaching strategies lead to different teaching efficiency point of view to talk about their own views, hope colleagues correct.
