几何历来是中学数学教学内容的一个难点,也是素质教育的一个突破口。点线面系统教学的核心任务是让学生树立空间概念;要紧紧抓住几何学与其它数学内容在教学方法上的相似性展开教学;制作立体模型,让学生手脑并用是培养学生的最佳辅助手段。
Geometry has always been a difficult point in middle school mathematics teaching content, but also a breakthrough in quality education. The key task of point-line surface system teaching is to let students establish the concept of space; to grasp the similarity of geometry and other mathematical contents in teaching methods; to make the three-dimensional model so that the students ’brain can be used to train students’ best Auxiliary means.
