高考《大纲》明确指出:“要注重学科的内在联系和知识的综合性,不刻意追求知识的覆盖面.要从学科的整体高度和思维价值的高度考虑问题,在知识网络交汇点处设计试题,使对数学基础知识的考查达到必要的深度”.据此可知:充分关注立体几何(包括空间向量)与其他知识在解题中的灵活、综合运用,很有必要,而且有利于提高分析问题、解决问题的实际能力.请看以下归类解析.
The “outline” of the college entrance examination clearly states: “We should pay attention to the internal relations of disciplines and the comprehensiveness of knowledge, and do not deliberately pursue the coverage of knowledge. We should consider the issues from the overall height of the subject and the height of thinking value, and design questions at the intersection of knowledge networks , So that the basic knowledge of mathematics to achieve the necessary examination of the depth of ”Thus, we can see: full attention to the three-dimensional geometry (including space vector) and other knowledge in the problem-solving flexible and comprehensive use, it is necessary, but also help to improve the analysis Problem, the actual ability to solve the problem.Please see the following classification analysis.
