在课标教材的几何部分,降低了对演绎推理能力的要求,加强了对几何直观、几何变换与几何应用能力的要求,这进一步说明了培养空间想象力在几何教学中的中心地位。因此,培养学生空间想象能力,要加强几何教学与实际的联系;处理好实物(或模型),几何图形与文字语言的关系;提高学生的逻辑思维能力;进行抽象问题形象化的训练,培养学生的几何直觉能力。
In the geometric part of the textbook teaching materials, the requirements on the ability of deductive reasoning are reduced, and the requirements on geometrical intuition, geometric transformation and geometric application are strengthened, which further illustrates the central position of culturing space imagination in geometry teaching. Therefore, to cultivate students 'spatial imagination ability, it is necessary to strengthen the connection between geometry teaching and reality; to handle the relationship between objects (or models), geometry and language; to improve students' ability of logical thinking; to carry out the visualization of abstract problems to train students Geometrical intuition ability.
