几何直观不仅在学习“图形与几何”中发挥着不可替代的作用,而且贯穿整个数学学习过程。教师应通过培养学生的识图、作图能力和利用多媒体对概念形成能力等培养学生的几何直观能力。
Geometry not only plays an irreplaceable role in learning “Graphics and Geometry ”, but also runs through the entire mathematics learning process. Teachers should cultivate students ’geometric intuition by cultivating students’ knowledge, drawing ability and using multimedia to form concepts.
