几何是一门研究图形性质的学科.图形教学是平面几何中不可缺少的一个重要环节,而识图又是几何图形教学的一个重要组成部分.所谓识图,简单地说就是指对几何图形的认识能力.在教学中指导学生正确识图,对于培养学生的观察能力和空间想象能力都将起到重要作用.本文就如何提高学生的识图能力谈几点教法:I.指导学生看图,要告诉学生看图的方法和步骤,让他们多练习看图,指导学生发现一般规律.如下图,问:图①中有几条线段?图②中有几个角?
Geometry is a discipline that studies the nature of graphs. Graphics teaching is an indispensable part of plane geometry, and graphing is an important part of geometry teaching. The so-called mapping, simply refers to the geometry Understanding ability. Instructing students to correctly map in teaching will play an important role in cultivating students’ ability to observe and space imagination. This article will discuss several ways to improve students’ ability to read pictures: I. Instruct students to read pictures , To tell students how to see the map and the steps, let them practice drawing, guide students to discover the general rules. The following diagram, Q: There are several lines in Figure 1? Figure 2 has a few corners?
