我们在高中阶段的数学学习之中,函数是其中非常重要的一部分内容。但是因为其所具有的抽象性,极容易挫败学生的学习积极性。运用图形计算器则可以很好地提升我们对函数内容的理解,感悟数学学习的本质。基于此,本文对图形计算器在高中函数学习中的作用和意义进行分析和研究,以期能够为学生的学习,以及相关人员的探索提供借鉴。 We are in high school mathematics learning, the function is a very important part of it. However, because of its abstract nature, it is very easy to frustrate the enthusiasm of students. The use of graphical calculator can be very good to enhance our understanding of function content, perception of the nature of mathematical learning. Based on this, this paper analyzes and studies the function and significance of the graphic calculator in the high school function learning in order to provide reference for the students’ learning and the exploration of relevant personnel.
