概念是最基本的思维形式。数学中的命题,都是由概念构成的,数学中的推理和证明,又是由命题构成的。因此,数学概念的教学,是整个数学教学的一个重要环节。正确的理解数学概念,是掌握数学知识的前提,数学概念好比支点,而数学法则、定理好比杠杆。可见概念的重要性。初中阶段概念较多,怎样组织教学,才能使学生更好地掌握呢?本人在多年教学中,总结出概念教学的三注重,收到了良好的效果。一、注重联系现实原型,对概念作解释
Concept is the most basic form of thinking. The propositions in mathematics are all formed by concepts. The reasoning and proof in mathematics are constituted by propositions. Therefore, the teaching of mathematical concepts, mathematics teaching is an important part of the whole. Correct understanding of mathematical concepts is a prerequisite for mastery of mathematical knowledge, mathematics concepts such as fulcrum, and mathematical rules, theorems like leverage. Visible concept of importance. The concept of junior high school more, how to organize teaching, in order to enable students to better grasp it? In my teaching for many years, summed up the concept of the three stresses, received good results. First, pay attention to contact the real prototype, to explain the concept
