人的智力表现是多元的,有的善于形象思维,有的长于计算,有的擅长逻辑思考。一些学生不太适应数学概括、归纳、抽象的思考方式。如何帮助这些学生,使他们也能尽快地掌握数学思考方法,教学中常用比喻是很好的办法,能使学生比较形象地领会数学概念。比喻就是打比方。在描写事物或说明道理时,用和它有相似点的事物或道理打比方。达到两者相互沟通,可使数学重难点变得浅显易懂。下面谈谈自己在教学中的实践尝试。一、提前渗透时,利用比喻让概念定义通熟易懂
Man’s intellectual performance is diverse, and some are good at image thinking, some longer than the calculation, and some good at logical thinking. Some students are not adapted to mathematical summation, induction, abstract way of thinking. How to help these students so that they can grasp the mathematical thinking method as soon as possible, and the common analogy in teaching is a good way to enable students to comprehend the mathematical concepts vividly. Analogy is to play analogy. In the description of things or explain the truth, with something similar to it or analogy. To achieve mutual communication between the two, can make mathematics heavy and difficult to become easy to understand. Here to talk about their own practice in teaching practice. First, infiltration in advance, the use of metaphor to make the concept of definition easy to understand
