立体几何是数学教学中的一个难点,对学生来讲,学好立体几何也是一个难点。我经过十几年的教学实践,及教学中学生的反馈情况,总结出了一些学习立体几何的方法,并且在教学中得到了一些收获,愿与同仁商榷。一、立体几何兴趣的培养培养兴趣是学好立体几何的首要条件,没有兴趣,一切都无从谈起。 Three-dimensional geometry is a difficult point in mathematics teaching. For students, learning solid geometry is also a difficult problem. After more than ten years of teaching practice and the feedback of middle school students, I have summarized some methods of learning three-dimensional geometry, and I have gained some achievements in teaching. I would like to discuss with my colleagues. First, the cultivation of interest in three-dimensional geometry Cultivation of interest is the prerequisite for learning a good three-dimensional geometry, no interest, everything is impossible to talk about.
