浅谈用模块化教学求摩擦力

On the Use of Modular Teaching for Friction

职高学生学习摩擦力,会出现静摩擦、最大静摩擦、滑动摩擦区分不清,往往错误百出,浅尝辄止。如果在教学中做大量练习,有时候反而是越练越乱。因此,在教师的指导下,建立物理学习模块,如水平地面上的物体受力模块,竖直面上物体受力模块,斜面上物体受力模块,分类归纳一些求摩擦力的典型办法,通过递进学习,有助于学生提升对摩擦力的认识,更重要的是形成正确的物理解题逻辑。

When vocational high school students learning friction,they will cannot distinguish static friction,maximum static friction,and sliding friction. Do a lot of practice in the teaching,and sometimes the more practice,the more mistakes.Therefore,under the guidance of teachers,establish physical learning modules,such as the force module on horizontal ground,the force module on vertical ground,and the force module on the slope ground. The paper makes classifications and inductions of some typical methods for friction,which will help students to raise awareness of friction through progressive learning. What more important is to form a correct logic to solve physical problems.
