单调性是函数性质的重要方面,学生在此前的函数学习过程中已经研究了一些函数的增减性,但是相关研究还比较肤浅,而且没有对其增减性进行明确定义,相关单调性的判断仅仅只是通过图像来进行说明。因此,本节课所讲的人教B版《数学》“函数的单调性”可以认为是对此前学习的进一步深化和提高。1目标分析让学生通过由直观到抽象,以图识数的方式来认识函数的单调性。在该过程中,学生以自我探究的方式来体会数学概念的形成过程,从而深刻理解函数图 Monotonicity is an important aspect of the nature of the function. Students have studied the additions and subtractions of some functions during the previous function-learning process, but the related studies are still superficial. There is no clear definition of the addition or subtraction, and the monotonicity of judgments Just through the image to explain. Therefore, people who teach this lesson teach B version of “Mathematics” “monotonicity of function ” can be considered to further deepen and improve previous learning. 1 Objectives Analysis allows students to understand the monotonicity of functions by visualization to abstraction. In the process, students realize the process of forming mathematical concepts in a self-exploring way, so as to deeply understand the function diagrams
