新课改以来,立体几何被分为必修与选修两个部分,旨在培养与提高高中生的几何直观、直觉思维、空间想象、论证推理等能力。然而,很多高中生在学习立体几何的时候感到难度很大,甚至很多学生对学习立体几何产生一种畏难心理。那么,新课改下的高中立体几何应如何教学呢?下面,笔者对此展开研究与讨论。 Since the new curriculum reform, three-dimensional geometry has been divided into compulsory and elective two parts, aimed at training and improving high school students geometric intuition, intuition thinking, spatial imagination, demonstration reasoning and other capabilities. However, many high school students find it difficult to learn solid geometry. Even many students find it hard to learn solid geometry. Then, the new curriculum under the high school three-dimensional geometry should be how to teach it? Here, I start to study and discussion.
