根据新课程标准,“立体几何初步”这一章首先通过直观感知、观察,发现柱、锥、台、球及其简单组合体的结构特征,然后归纳出空间中线面平行,垂直的判定和性质,这样就把对事物的感性认识作为理论研究的基础,这种做法更符合人们的认识规律.这是与旧立体几何教材的重要区别.作为立?
According to the new curriculum standard, the chapter “The Preliminary Study of Stereoscopic Geometry” first identifies and observes the structural features of columns, cones, tables, spheres and their simple combinations through intuitionistic observation, and then summarizes the judgment and properties of parallel and vertical lines in the space , So put the perceptual knowledge of things as the basis of theoretical research, this approach is more in line with people’s understanding of the law, which is an important difference between the old stereoscopic textbooks.
