高中立体几何学习过程中,学生应以特殊几何体的认识作出直观感受,在教学中鼓励学生善于观察,发现问题,从特殊图形思考,猜想得到一般图形的性质、结论,引导学生通过直觉去判断。有科学家说直觉大多是错误的,但直觉是一切创新的源泉。结合理论,去证明认识正确与否,发现正确规律,拓宽空间思维,达到培养空间想象能力和教学的目的。一、空间几何体的认识教学中通过影片或同学亲身体验或参观的各种建筑,体会旋转体,对称性的运用,曲面设计的运用等,感受美好事物,发现生活中几何之美,激发创造灵感。“横看成岭侧
During the process of high school three-dimensional geometry learning, students should make intuitive perceptions of special geometric bodies. Students should be encouraged to observe and discover problems in teaching. From special graphic thinking and speculation, they should get the nature and conclusion of general graphics and guide students to judge through intuition. Some scientists say intuition is mostly wrong, but intuition is the source of all innovation. Combination of theory, to prove that the correct understanding or not, to find the correct law, broaden the space of thinking, to achieve the imagination of space and teaching purposes. First, the understanding of spatial geometry Through the film or classmates personally experience or visit the various buildings, experience rotating body, the use of symmetry, the use of surface design, feel good things, discover the beauty of life geometry, inspire the creation of inspiration. ”Horizontal as the ridge side
