立体几何是高中数学的重要组成部分.很多学生觉得立体几何难学,是因为立体几何具有高度抽象性和空间性的特征,而这些特征就使立体几何对于学生的抽象的空间想象能力有着很高的要求.对于大多数高中学生而言,高度的空间想象能力还是属于一种较高层次的要求.在立体几何教学中,教师要培养学生的空间想象能力.下面结合自己的教学实践谈点体会.一、激发学生学习立体几何的兴趣兴趣是学习活动的重要推动力.一旦学生对于某个事物投入兴趣,自然会展开积极的探索和思
Three-dimensional geometry is an important part of high school mathematics.Many students think three-dimensional geometry is difficult to learn because of the highly abstract and spatial characteristics of three-dimensional geometry, and these three-dimensional geometry makes students have a high degree of abstract spatial imagination For most high school students, a high degree of spatial imagination or a higher level of the requirements.In the three-dimensional geometry teaching, teachers should cultivate students’ spatial imagination. The following combination of their own teaching practice talk about experience First, to stimulate students interest in learning three - dimensional geometry is an important driving force for learning activities.Once students are interested in something, it will naturally launch a positive exploration and thinking
