几何学是研究现实世界中物体的形状、大小与位置关系的数学学科。人们通常采用直观感知、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。认识空间图形,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,是高中阶段数学必修系列课程的基本要求。近年来,立体几何教学的内容发生了很大的变化,教育内涵更加丰富,随之而来的是立体几何的教学方式必须做出相应的调整和变革,以适应这种变化。
Geometry is a mathematical discipline that studies the shape, size, and location of objects in the real world. People usually adopt the methods of intuition perception, operation confirmation, speculative argumentation and merit calculation to recognize and explore the geometry and its properties. It is the basic requirement of the high school math compulsory course to recognize the space figure, cultivate and develop the space imagination ability, reasoning and demonstrating ability, the ability to communicate in the graphic language and the geometric intuition ability. In recent years, the content of the three-dimensional geometry teaching has undergone great changes, the education connotation is more abundant, followed by the teaching of three-dimensional geometry must make the appropriate adjustments and changes to adapt to this change.
