数学是一门抽象性学科,如果只靠“一张嘴、一块黑板、一支粉笔”很难给学生讲解清楚那些复杂的数学概念,更不能把几何图形中的关系生动展示出来,又加之初一学生缺乏空间想象能力,因此,传统教学模式很难激发学生学习几何的兴趣。但是,如果运用多媒体辅助教学,那形象的画面、详细的讲解、悦耳的音乐定会让学生耳目一新,定会让学生主动参与教学过程。下面是我在人教 Mathematics is an abstract discipline. If we only rely on “a mouth, a blackboard and a piece of chalk,” it is very difficult for students to explain complicated mathematical concepts and to show the relationship between geometric shapes vividly. The freshmen lack space imagination, so the traditional teaching model is very difficult to stimulate students interest in learning geometry. However, if multimedia-assisted teaching is used, the images, detailed explanations and pleasing music are sure to refresh the students. Students are expected to actively participate in the teaching process. Here is what I teach
