《坐标系与参数方程》教学的几点建议

Some Suggestions on the teaching of coordinate system and parametric equation

坐标思想的奠基人是法国数学家笛卡尔。《坐标系与参数方程》是高中数学选修系列4-4的内容,是江苏省高考数学附加题命题的内容之一。坐标系与参数方程知识的学习是在解析几何的基础上开始的,学生普遍认为入门比较容易,参数方程对解决解析几何问题提供了一种新的思想方法,但从历年高考阅卷反馈情况来看,学生深入理解并熟练应用还存在一定的问题。本文从教师教学的角度给出几点建议,以供参考。

the founder of the coordinate thought is the French mathematician Rene Descartes. "Coordinate system and parametric equation" is the content of 4-4 in the high school mathematics elective series,which is one of the contents of the proposition of the additional topic of the college entrance examination in jiangsu province. Coordinate system and the parameter equation of knowledge learning is on the basis of analytic geometry,students generally think that it is easy to entry parameter equation to solve the problem of analytic geometry method provides a new thought,but from the calendar year the university entrance exam read feedback,students understanding and skilled application also has certain problem. This paper gives some Suggestions from the Angle of teacher teaching for reference.
