一、图形计算器于数列有多元表征优势图形计算器能为学生提供“多元联系表征”的学习环境,帮助学生直观感受递推和叠加思想,在符号语言与表格、图象间形成一有效的理解通道,从而对我们真实理解数学产生着重要影响.事实上从数学学习心理的角度看,不同的数学思维形式、它们之间的转换及表达方式是数学学习的核心,用多种表达形式表示数学对象,从而透过现象把握数学本质,已然成 First, the graphical calculator in a series of multiple characterization advantage Graphical calculator can provide students with “multiple connection characterization” learning environment to help students intuitively feel recursion and superimposition of ideas in the symbolic language and forms, images form a Effective understanding of the channel, and thus our true understanding of mathematics have a significant impact.In fact, from the perspective of mathematical learning psychology, different mathematical thinking, conversion and expression between them is the core of mathematical learning, with a variety of expressions The formal representation of mathematical objects, so as to grasp the essence of mathematics through phenomena, has become
