空间观念是《课标(2011年版)》提出的核心词之一.投影与视图是培养学生空间观念的重要内容.本章主要研究了中心投影、平行投影和物体的三视图的有关知识。内容的呈现注重从生活实际取材,重视了知识的形成过程,把空间图形转化为平面图形进行研究.教学时应充分借助于学习平面几何的经验,淡化形式,注重实质,重视空间观念的培养. The concept of space is one of the core words proposed in “Curriculum Standard (2011 Edition).” Projection and view are important contents in cultivating students’ concept of space.This chapter focuses on the knowledge of central projection, parallel projection and three views of objects. The presentation of content focuses on the material from life, attaches importance to the process of knowledge formation, and transforms the space graphics into plane graphics, and should make full use of the experience of learning plane geometry in teaching so as to fade the form, pay attention to substance, and attach importance to the cultivation of space concepts.
