高二教科书(全日制普通高级中学教科书《数学》第二册,人民教育出版社出版)有下(A)、下(B)两种版本.这两种版本的主要区别在于立体几何这一章,下(A)基本上还是采用传统的教学方案,只是精简了教学内容,减少了教学时间;而下(B)则是用空间向量这一工具来处理立体几何的平行、垂直、角与距离等问题.从当前世界各国基础数学教育应达到的水平看,在高中用向量的方法来处理立体几何问题已是一种必然趋势,因而教育部对采用下(B)的学校曾经给予
High school textbooks (full-time ordinary high school textbooks, “Mathematics” Book 2, People’s Education Press) There are two versions (A), under (B) .The main difference between these two versions is the chapter of solid geometry, The next (A) is still basically using the traditional teaching program, but to streamline the teaching content, reducing the teaching time; and (B) is the use of space vector tool to deal with three-dimensional geometry of the parallel, vertical, angle and distance Problem.According to the current level of basic math education in all countries in the world, it is an inevitable trend to deal with the problem of three-dimensional geometry by using vector method in high school. Therefore,
