在高中数学知识中,函数有着举足轻重的作用,函数知识体现的是变量数学理论的探究,是对传统数学知识的突破与挑战,函数知识同高中数学知识体系中的其他数学知识原理密切相关,例如:解析几何中数形结合思想就蕴含着函数知识理论,学生学好函数,掌握函数这一重要知识点,意味着收获了一种全新的数学思维方法,对于以后其他数学知识点的学习能够发挥有效的支持与辅助作用,因此,教师掌握科学的函数教学 Function in high school mathematics plays a decisive role. Functional knowledge reflects the study of variable mathematical theory, which is a breakthrough and challenge to traditional mathematical knowledge. Function knowledge is closely related to other mathematical knowledge principles in high school mathematics knowledge system. For example, : Analytic geometry in combination with the number of ideas contains the theory of functional knowledge, students learn the function, grasp the important function of the knowledge point, means that harvest a new way of thinking of mathematics for the future of other points of knowledge of mathematics learning can play an effective Support and support role, therefore, teachers master the scientific function of teaching
