向量是沟通代数、几何与三角函数的一种工具,有着极其丰富的实际背景,在数学和物理学科中具有广泛的应用,是高中数学的重要内容.“课标”中明确指出要让学生了解向量丰富的实际背景,理解平面向量及其运算的意义,能用向量语言和方法表述和解决数学和物理一些问题,发展运算能力和解决实际问题的能力.笔者在听课中了解到,部分学生指出向量的概念太多太碎,容易遗忘混淆,不清楚为何要学习向 Vector is a tool for communication algebra, geometry and trigonometry, has a very rich practical background, has a wide range of applications in mathematics and physics, is an important part of high school mathematics. Students understand the vector-rich practical background, understand the meaning of plane vector and its operation, can use vector language and method to express and solve some math and physics problems, develop computing power and solve practical problems .In the lecture I learned that part of Students pointed out that the concept of vector too much too fragmented, easy to forget the confusion, not sure why you want to learn
