讲授知识的同时,注意培养能力、发展智力,已成为当前教学中的重大任务。本文仅就数学复习中的一些做法谈几点体会。一、数、式、形紧密结合,充分利用几何图形培养学生的探索能力。根据已知的数量关系正确地作出图形是加深理解数学概念的重要环节;借助图形分析数量关系又是解题的有效方法。因此,利用图形探索解题思路有利于学生思维能力的培养。
While teaching knowledge, paying attention to cultivating ability and developing intelligence has become a major task in current teaching. This article only talks about some of the practices in the review of mathematics. First, number, style, shape closely integrated, make full use of geometric graphics to develop students’ exploration capabilities. Correctly making graphs based on known quantitative relationships is an important part of deepening the understanding of mathematical concepts; using graphs to analyze quantitative relationships is an effective way to solve problems. Therefore, the use of graphic exploration to solve problems is conducive to the cultivation of students’ thinking ability.
