初中平面几何课的入门教学是广大数学教育工作者普遍关注的一个难点。笔者在自己多年的教学实践中体会到,突破这个难点的关键是如何使学生建立起掌握几何概念、图形、语言、推理等新知识体系的几何学习方法。其主要作法是: 一、牢固建立几何概念几何概念总是和某种图形有联系,这是平面几何的本质特征。概念教学应紧紧抓住和围绕这一特征来 The introductory teaching of the junior high school plane geometry class is a common difficulty for the majority of math educators. In my own years of teaching practice, the author realized that the key to breaking this difficulty is how to enable students to establish a geometric learning method that masters new concepts such as geometric concepts, graphics, languages, and reasoning. Its main approach is: First, firmly establish the geometric concept The geometric concept is always associated with a certain figure, which is the essential feature of the plane geometry. Conceptual teaching should firmly grasp and revolve around this feature
