“向量”的概念现已引入中学 .“平面向量”已成为高中数学试验教科书中独立成章的内容 ,它的引入给传统的中学数学内容注入了新的内涵 .不仅如此 ,“平面向量”所蕴含的丰富的数学思想方法 ,如 :数形结合、构造建模、化归转换、平移变换等 ,有益于发展学生的思维能力 ,激发其 The concept of “vector” has been introduced into middle school. “Plane vector” has become an independent chapter in the high school mathematics test textbook. Its introduction has injected new meaning into the traditional middle school mathematics content. Not only that, the “planar vector” contains The rich mathematics and thinking methods, such as combination of number and shape, structure modeling, transformation transformation, translation transformation, etc., are beneficial to the development of students’ thinking ability and inspire them.
