通过对近十年间全国卷立体几何题中几何法和向量坐标法的应用概况的统计,及新课标对几何法和向量法的目标分析,从文、理科学习对比中彰显教材对学生能力培养的侧重点,几何法和向量法对比中突出向量法的便捷美,重新阐明了立体几何命题的出发点及几何问题坐标化——算法思想的本质. Through the statistics of the application of the geometric method and the vector coordinate method in the national volumetric solid geometry in the recent ten years and the target analysis of the new curriculum standard method by the geometric method and the vector method, The focus of this work is to highlight the convenient beauty of the vector method in comparison with the geometric method and the vector method, and to redefine the starting point of the geometric geometric proposition and the problem of how to coordinate the geometric problem - the nature of the algorithmic thought.
