一、教学内容分析函数是高中数学的核心内容,是历年高考考查的重点和热点。函数的思想方法贯穿了高中数学的始终。幂函数是学习了指数函数,对数函数之后高中数学中又一基本初等函数,对于研究函数图像及性质(如比较大小,单调性,奇偶性等)起到巩固和延伸的作用。二、学生学习情况分析本节课是在学生对指数函数和对数函数的图像和性质有了一定的认识并且能进行简单应用的基础上继续学习幂函数。学生“数——形——性质——应用”的思维模式已基 First, the teaching content analysis function is the core content of high school mathematics, college entrance examination over the years is the focus and hot spot. The method of thinking of function runs through high school mathematics from beginning to end. Power function is to learn the exponential function, the logarithm function after high school mathematics and a basic elementary function, to study the function of the image and the nature (such as size, monotonous, parity, etc.) to play the role of consolidation and extension. Second, the analysis of student learning This lesson is students in the exponential and logarithmic function of the image and nature of a certain understanding and can be simple to apply based on the continuous learning power function. Students “number - form - nature - application ” thinking mode has been based
