刚接触平面几何这门学科的初中学生,对几何图形充满了好奇心和求知欲。作为一个中学数学教师就要善于因势利导,启发学生的学习积极性。在教学实践中,我们有如下点滴体会:一、重视新课的引入。1.利用教具引入新课。为了帮助学生弄清平面几何的概念和定义、定理,凡是能用教具引入新课的要尽量运用教具,加强教学的形象化、直观性,便于 Junior high school students who have just touched Plane Geometry are full of curiosity and curiosity about geometry. As a middle school mathematics teacher should be good at making the best use of circumstances to inspire students' enthusiasm for learning. In teaching practice, we have the following bit of experience: First, pay attention to the introduction of the new lesson. 1. Use teaching aids to introduce new lessons. In order to help students to understand the concept and definition of plane geometry theorem, who can use teaching aids to introduce a new class to try to use teaching aids to enhance the teaching of visualization, intuitive, easy
