一、空间线面关系用向量处理的尝试1992年,上海颁布的《高级中学数学学科标准(草案)》(简称一期课改的课标)增加了向量内容。当时,世界上许多国家已没有独立的立体几何课程。鉴于为更好地获得对数学本质的理解,几何教材内部的逻辑联系比几何与代 I. Attempt to use vector processing for spatial line-plane relationships In 1992, the “High School Mathematics Standards (Draft)” (abbreviated as the curriculum standard for first-year curriculum reform) promulgated by Shanghai increased the vector content. At that time, many countries in the world had no independent three-dimensional geometry courses. Given that in order to gain a better understanding of the nature of mathematics, the logical connection within a geometry textbook is more than geometry and generation.
