立体几何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,学生在立体几何的学习中存在诸多困难,诸如空间想象能力的欠缺、逻辑推理能力的不足等,这些都对学生进一步学好数学产生了影响。为了激发学生学习立体几何的热情,中国人民大学附属中学教师有效地将信息技术与立体几何结合起来,开发了“三维软件、3D建模打印与立体几何”课程,为学生创建了良好的认知环境,培养了学生的空间想象能力和逻辑推理能力,提高了课堂教学效果。
Three-dimensional geometry is a mathematical discipline that studies the shape, size and position of objects in the real world. Students have many difficulties in learning three-dimensional geometry, such as lack of spatial imagination ability and lack of logical reasoning ability, which further improve students’ abilities Math has an impact. In order to arouse students’ enthusiasm for learning solid geometry, the middle school teachers attached to Renmin University effectively combined information technology with solid geometry to develop a course called “3D Software, 3D Modeling Printing and Stereo Geometry” to create a good Cognitive environment, cultivate students’ ability of spatial imagination and logical reasoning, improve the effect of classroom teaching.
