中学向量教学内容和体系初探

Exploration on the contents and logical systemof vector in secondary school

中学向量的教学内容除核心内容外 ,可考虑增加向量积 .教材应以学生的心理发展为依据 ,建立合理的螺旋式体系 .对于向量的运算 ,宜先用几何方法引入 ,然后推得向量的坐标运算公式 ,再证明各种运算律 .

In addition to the key contents of vector teaching material in secondary school, vector product should also be added.Spiral teaching system can be set up rationally in accordance with students′ mental development. Vector operation can be defined by geometric method, and its properties can then be rationally demonstrated.
