现代教学着眼于开发学生的智力,培养学生的能力。运算能力、逻辑思维能力、空间想象能力已逐渐形成,运用数学知识来分析解决实际问题。对于空间想象能力学生最难达到,尤其体现在立方体几何中。空间想象能力就是人们对客观事物的空间形式进行观察、分析、抽象、概括,在头脑中形成反映客观事物的形象和图像,正确判断空间元素之间的位置关系和度量关系的能力,它可以看成是逻
Modern teaching aims to develop students ’intelligence and develop students’ abilities. Computational ability, logical thinking ability, spatial imagination has been gradually formed, the use of mathematical knowledge to analyze and solve practical problems. The most difficult for students to achieve spatial imagination, especially in the cube geometry. The ability of spatial imagination is the ability of people to observe, analyze, abstract and summarize the spatial forms of objective things, form images and images reflecting objective things in their minds, and correctly judge the positional relationship and the metric relationship between spatial elements. It can be seen Into logic
