充分条件和必要条件是在构成許多数学命題时要用到的最重要的概念。不了解它們的邏輯关系,学生就不能透彻地理解定理的含义,不能深刻地認識定理的証明和解題过程。因此,为提高学生数学知識的貭量以及对他們加强邏輯推理和分析問題的訓练,就不得不要求学生对同一个命題中的前提和結論之間的关系以及命題与命題之間的关系有清楚的認識。本文就我們在这方面教学实践中得到的点滴体会来談一談,以供同志們参考并請指教。
Sufficient conditions and necessary conditions are the most important concepts to use when constructing many mathematical propositions. Without understanding their logical relationship, students cannot fully understand the meaning of the theorem and cannot profoundly understand the proof of the theorem and the problem-solving process. Therefore, in order to improve the students’ mathematical knowledge and strengthen their training in logical reasoning and problem analysis, they have to ask students to have a relationship between the premise and conclusion in the same proposition and the relationship between the proposition and the proposition. Clear understanding. This article talks about our experience in teaching practice in this area. Let us use it as a reference for comrades and ask for advice.
