函数是高中数学代数部分的重点及难点,而函数单调性又是函数重要的基本性质之一,是学习函数的周期性、奇偶性等性质的基础,但因其逻辑性和抽象性较强,函数单调性一直以来都是学生学习的难点之一。教师要从整体分析的角度把握教材,利用数形结合思想进行教学,研究函数单调性的习题策略,总结谈函数单调性的教学策略。 Function is one of the most important and difficult points in math algebra of high school. The function monotonicity is one of the most important basic functions of the function. It is the basis for learning the periodicity and parity of the function. However, due to its high logic and abstraction, Function monotonicity has always been one of the difficulties for students to learn. Teachers should grasp the teaching materials from the perspective of overall analysis, use the combination of number and form to combine teaching methods, study the monotonicity of the exercises, and summarize the teaching strategies of the monotonicity of the functions.
