在高中阶段,立体几何普遍成为一些学生的学习心病,刚学时担心学不好,学习中好多地方会力不从心,毕竟比较抽象;复习中常常丢三落四,定理的推理模式使用不当。这个定理、那个性质的,确实让人感到有点“乱”。但任何一门学科都有它的窍门,只要把握好,肯定能学好。我想从四个方面谈谈这些年来对于立体几何的教 In high school, three-dimensional geometry generally become some students learning heart disease, just learning to worry about learning is not good, learning a lot of places will be powerless, after all, more abstract; review often omission theorem reasoning mode improper use. This theorem, that nature, really makes people feel a little “messy.” However, any discipline has its own tricks, as long as a good grasp, certainly can learn. I would like to talk about the teaching of solid geometry over the years from four aspects
