我们知道,通过立体几何的教学,要培养学生的空间想象能力,逻辑思维能力和综合运用数学知识的能力,空间中,两条直线、直线和平面、平面和平面的位置等内容是学好立体几何的基础,也是培养能力的重点,在讲完这部分内容之后,我们进行了小结,用一道典型例题复习了这部分知识,收到比较好的 We know that through the teaching of solid geometry, it is necessary to cultivate students’ spatial imagination ability, logical thinking ability and the ability to comprehensively use mathematical knowledge. In space, the contents of two straight lines, straight lines and planes, planes, and planes are good for learning solid geometry. The foundation of this is also the focus of training ability. After we have finished this part of the content, we have made a summary, reviewed this part of the knowledge with a typical example, and received better
