几何作图法充分运用“数形结合”的思想,把抽象而繁杂的物理过程转化成一幅幅具体而清晰的物理图像,将物理问题转化成一个个几何问题.通过几何图形所蕴含的物理意义从图中来寻求答案,既直观形象,又易于理解,且避免了一些繁琐的推理与计算,对启迪学生的思维、拓展学生的思路、提高学生的学习兴趣有着不可替代的重要意义.下面通过几个具体实例,来展示一下几何作图法在高中物理教学中的妙用.
The geometric drawing method makes full use of the idea of “mathematical combination” to transform the abstract and complicated physical processes into concrete and clear physical images, transforming the physical problems into geometric problems. Physical meaning Seeking answers from the figure is both intuitive and easy to understand, and avoids some cumbersome reasoning and calculation. It has an irreplaceable significance to enlighten students’ thinking, expand students’ thinking and enhance students’ interest in learning. The following through a few specific examples to demonstrate the geometric drawing method magical effect in high school physics teaching.
