摘要
基于多元表征理论的数学教学是利用丰富的外在表征凸显数学对象的各方面属性,完善其结构刻画,增强其吸引力和趣味性。以"函数的概念"为例,探讨多元表征理论在教学设计中的应用,利用函数的不同表征之间的转换来引导学生认识发展函数概念的必要性,经历概念的形成过程,抓住概念的本质,以此帮助学生更好地理解函数的概念,进一步发现学习的乐趣。
Mathematics teaching based on the multiple-representations theory,can use abundant external characterization to highlight the mathematical objects in all aspects,improve the overall structure and significance of mathematics,and enhance the attraction and interest of mathematics.Taking the function concept of high school as an example,this paper discusses the practical application of multiple-representations theory in teaching design,uses the transformation between different representations of functions to guide students to understand the necessity of developing function concept,undergoes the process of concept formation,and captures the essence of concept,so as to help students better understand the concept of function and further discover the pleasure of learning.
