立体几何历来是部分学生学习的难点,一部分学生觉得解析几何的难度要低于立体几何。新教材使用至今,笔者在立体几何的教学中发现教材在处理知识点方面与以往教材有了很大的变化,本文通过空间几何体的表面积这节课的教学过程来简单谈谈这方面的感受。一、新教材中对于此内容的目标定位1.内容简介 Three-dimensional geometry has always been part of the difficulties of student learning, some students feel that the difficulty of analytic geometry is lower than the three-dimensional geometry. The use of new textbooks so far, the author found in the teaching of three-dimensional geometry textbook in the processing of knowledge points with the previous teaching material has changed a lot, this article through the geometry of the surface space of this lesson teaching process to simply talk about this feeling. First, the new textbook for the content of this target 1. Content brief introduction
