在小学数学的立体图形教学中,由于小学生的抽象思维能力和空间观念比较弱,学生对立体图形的学习感到非常抽象,不容易理解。教学中如果充分利用多媒体的图文并茂、声色同步这一优点,变抽象为直观、化静为动,通过多媒体动态的演示,展示几何图形的变化。课堂教学中合理运用CAI课件,让静止的形体动起来,把较难想象的立体几何图 In the three-dimensional graphics teaching of elementary mathematics, because of the abstract thinking ability and space concept of the pupils are relatively weak, the students are very abstract in the learning of the three-dimensional graphics and are not easy to understand. If you make full use of multimedia multimedia teaching in teaching, the advantages of sound synchronization, abstraction into an intuitive, static and dynamic, through the dynamic presentation of multimedia, display geometry changes. The rational use of CAI courseware in classroom teaching, so that static body move up, the more difficult to imagine the three-dimensional geometry
