《普通高中数学课程标准(实验)》(下称《标准》)指出,通过立体几何初步的教学,使学生经历直观感知、操作确认、思辨论证、度量计算等方法认识和探索几何图形及其性质的过程;使学生直观认识和理解空间点、线、面的位置关系,能用数学语言表述有关平行、垂直的性质与判定,并对某些结论进行论证;培养和发展学生的空间想象能力、推理论证能力、运用图形语言进行交流的能力以及几何直观能力. “Ordinary high school mathematics curriculum standards (experiment)” (hereinafter referred to as “standards”) points out that through the preliminary teaching of solid geometry, students experience intuitive perception, operation confirmation, speculative argumentation, and metric calculations to understand and explore geometric shapes and their properties. The process enables students to intuitively understand and understand the positional relationship of spatial points, lines, and surfaces, and can use mathematical language to express the nature and judgment of parallelism and perpendicularity, and to demonstrate certain conclusions; to cultivate and develop students’ spatial imagination ability. Demonstrate theoretical competence, the ability to communicate using graphical languages, and the ability to visualize geometry.
