推理能力是最重要的数学能力之一,直接影响到学生的学业水平,我们采取以下教学尝试:1.认真落实三种数学语言(文字语言、符号语言、图形语言)的互译;2.讲清寻找解题思路的一般方法:综合法、分析法、综合分析法;3.引导学生将各知识点系统化,明确各命题间推出关系为整体数学暗线;4.关注从平面几何到立体几何的发展以及公理化构成的规律,为后面的系统学习奠定基础。我们从低年级开始渗透命题教学,加长教育的时间段,这就极大地加强了“学会推理”这条主线的教学,使学生解决问题的能力达到更高的层次,是实现数学教育总目标的有力举措。
Reasoning ability is one of the most important mathematical ability, which directly affects the students’ academic level. We try to do the following: 1. Conscientiously implement the translation of three kinds of mathematical languages (literal language, symbolic language, graphic language); Clearly looking for solutions to the general idea of solving problems: comprehensive method, analytical method, comprehensive analysis; 3. Guide students to systematize the various knowledge points, clear the relationship between the introduction of the proposition as a whole mathematical dark line; 4. Concerned from the plane geometry to solid geometry The development of justice and axiomatic composition of the law, lay the foundation for the following system learning. We begin to penetrate the proposition teaching and lengthen the period of education from the junior grades, which greatly strengthens the teaching of “learning reasoning” and enables the students to reach a higher level in their ability to solve problems. The goal of a powerful move.
