学用结合在高中数学教学中的理解,需要超越“学”好数学知识“用”以解题的层面,需要从数学在生活中的延伸,从数学促进社会发展的角度去思考。函数知识在国际通行的“体重指数”中有着显性的应用,可以让学生研究体重指数中的对应关系,并在数据采样与标准确定的过程中深化对函数的理解。学用结合可以成为高中数学教学的主线。
The combination of learning with mathematics teaching in senior high schools needs to go beyond solving the problems of “learning” good mathematical knowledge and “using” to solve problems, and it is necessary to think from the perspective of mathematics in promoting social development from the extension of mathematics in life . Function knowledge has a dominant application in internationally accepted “body mass index”, allowing students to study the corresponding relationship between body mass index and deepen the understanding of the function in the process of data sampling and standard determination. Combination of learning can become the main line of high school mathematics teaching.
