本文结合近五年江苏高考立体几何高考要求和题目进行了反思总结,即在立体几何教学时要培养学生数学空间想象能力和推理论证能力。其主要途径是抓好双基教学,加强对空间图形的看、画、做、思四方面的训练,同时正确认识推理论证能力和空间想象能力之间的联系。
In this paper, the recent five years, Jiangsu college entrance examination geometric geometry college entrance examination requirements and topics were reviewed, that is, in the teaching of three-dimensional geometry to cultivate students mathematical space imagination and reasoning ability. The main approach is to do a good job in double-based teaching, to strengthen the training of the four aspects of drawing, painting, doing and thinking of spatial figures, and at the same time, to correctly understand the connection between reasoning and argumentation and spatial imagination.
