函数是描述客观世界变化规律的重要数学模型,函数知识是高中新课程数学基础中的基础,它博大精深,包含了各种各样的知识点,是整个高中数学教学的一条主线、函数的思想方法贯穿于高中数学课程的始终。学生对函数知识的理解与掌握直接影响到整个高中阶段的数学学习质量与个人自身的发展。为此,对函数教学策略的探究显得尤为重要。 Function is an important mathematic model to describe the changing law of the objective world. Function knowledge is the basis of mathematics foundation of high school new curriculum. It is profound and contains a variety of knowledge points. It is the main line of mathematics teaching in high school. Throughout the high school mathematics curriculum has always been. Students’ understanding and mastery of functional knowledge have a direct impact on the quality of maths learning and the development of individuals themselves in the entire high school. For this reason, it is particularly important to explore the function teaching strategy.
