在初中平面几何的教学中,很多时候我们可以引导学生利用熟悉的纸片作为工具进行折叠操作,这样便具有一定的直观性,易于发现图形的本质特征。折叠在空间与图形的教学中是一种有效的探索图形性质的方法与手段。《课程标准》提出:“在教学中,应注重所学内容与现实生活的联系,注重使学生经历观察、操作、推理、想象等探索过程。”我们在教学中如能
In the teaching of plane geometry of junior middle school, we often guide students to use the familiar paper as a tool for folding operations, so that they have a certain degree of intuition and are easy to find the essential characteristics of graphics. Folding in space and graphics teaching is an effective way to explore the nature of graphics. “Curriculum Standards” put forward: “In teaching, we should pay attention to the relationship between what we learn and the real life and focus on making the students go through the exploration process of observation, operation, reasoning and imagination.” "
