数学是一门工具学科,又是一门基础学科。函数是高中数学的一个重要的基本概念,它渗透在数学的各部分内容中,一直是高考的热点和重点。在高中数学教学中,函数知识是高中代数的主线,函数内容占了很大的比重。教师应探索有效的函数教学策略,帮助学生更好地理解函数,使其在今后的学习中充分地运用函数知识来解决问题,进而提升高中学生的学习能力。一、整体把握函数的内容与要求,加深学生对函数思想的理解函数是学生在学习数学过程中首次接触的具有一般意义的抽象概念,此种概念能够衍生出不同的具体函数。学生在学习函数的过程中,通常需要长期的积累、多次练习才能够逐渐掌握函 Mathematics is a tool discipline, but also a basic discipline. Function is an important basic concept of high school mathematics. It infiltrates the contents of each part of mathematics and has always been the focus and hot point of college entrance examination. In high school mathematics teaching, functional knowledge is the main line of high school algebra, the function content accounts for a large proportion. Teachers should explore effective function teaching strategies to help students better understand the function so that they can fully use function knowledge to solve the problem in future study and then improve the learning ability of high school students. First, the overall grasp of the content and requirements of the function, to deepen the students understanding of the function of the function is the first time in the process of learning mathematics students contact abstract abstract concept, this concept can be derived from different specific functions. Students in the process of learning the function, usually need long-term accumulation, repeated practice to be able to gradually master the letter
