几何教学有三种不同形式的语言,即图形语言、文字语言及符号语言。教学中不仅要让学生掌握三种几何语言,还要培养学生对三种语言相互转化的能力。由于三种语言的特点不同,在几何教学中各自发挥的作用也不同,所以数学语言的教学往往是教学中的一个难点。本文我就自己在多年的教学中对这方面的体会谈谈自己的一些策略和做法。 There are three different forms of geometry teaching language, that is, graphics language, text language and symbolic language. Teaching not only allows students to master the three geometric languages, but also to train students in the three languages ​​into each other’s ability. Due to the different characteristics of the three languages, their respective roles in geometry teaching are also different, so the teaching of mathematical language is often a difficult teaching. In this article, I have myself talked about some of my own strategies and practices in this area during my years of teaching.
