学生在初学立体几何时,由于空间概念没有很好形成,空间想像力差,常常出现一些错误,这是学习中的正常现象,不足为怪。认真总结。及时纠正这些错误,提高空间想像力,提高逻辑思维能力都是十分重要的。归纳起来,学生在立体几何练习中的常见错误主要有以下四个方面。 When students begin to learn three-dimensional geometry, because the concept of space is not well formed, the imagination of the space is poor, and there are often some mistakes. This is a normal phenomenon in learning, and it is not surprising. Seriously sum up. Correcting these mistakes in time, improving spatial imagination and improving logical thinking skills are all very important. To sum up, the common mistakes of students in the three-dimensional geometry exercises mainly have the following four aspects.
