随着新课程的实施,向量进入了高中数学教材,特别是全日制普通高级中学教科书第二册(下B)把向量运用到立体几何的学习中,使得抽象的推理论证可以通过具体的代数计算来实现,弥补了一些学生想象力的不足.向量方法一度成为高中数学教学一道亮丽的风景,但美中不足的是上述教材对向量方法的介 With the implementation of the new curriculum, the vector has entered the high school mathematics textbooks, especially the second full-time ordinary high school textbooks (bottom B) to apply the vector to the study of solid geometry, so that the abstract theory of reasoning can be calculated through concrete algebra To achieve, to make up for the lack of some students’ imagination. The vector method once became a beautiful landscape of high school mathematics teaching, but in the ointment is the introduction of the vector method of the above teaching materials.
