在高中的立体几何教学中,使学生系统地掌握空间图形的基本性质,从而掌握一些简单的多面体和旋转体的画法及两积公式,发展学生的逻辑思维能力和空间想像能力,进一步培养应用这些知识发现问题、分析问题、解决问题的能力为教学的最终目的.但立体几何知识是高中数学学习的一个难点 In the high school of three-dimensional geometry teaching, students are required to systematically grasp the basic nature of spatial graphics, so as to master some simple polyhedron and rotating body drawing methods and two-volume formulae, develop students’ logical thinking ability and spatial imagination ability, and further train applications. These knowledge discovery problems, analysis of problems, ability to solve problems is the ultimate goal of teaching. However, the knowledge of solid geometry is a difficult point in high school mathematics learning.
