数学语言是数学知识的重要组成部分,是数学知识的载体,教师在数学教学过程中,要重视数学语言使用的准确性,这是数学教师的一个基本要求。如初中平面几何关于圆的切线问题中出现的“公共点”与“交点”的问题,如果教师不正确区分及讲解,则很容易使学生在知识结构中造成错误。 Mathematical language is an important part of mathematics knowledge and a carrier of mathematics knowledge. Teachers should pay more attention to the accuracy of mathematical language in mathematics teaching, which is a basic requirement of mathematics teachers. Such as junior high school geometry on the tangent of the circle appear in the “public point ” and “intersection ” problem, if the teacher does not correctly distinguish and explain, it is easy for students to make mistakes in the structure of knowledge.
