笔者在教学实践中自制教具、合理选择实验器材,既解决了高中物理实验中的难点,又方便了学生,还节约了开支,现介绍如下: 1.自制复写纸片和纸带 练习使用打点计时器;测定匀变速直线运动的加速度;验证机械能守恒定律;验证牛顿第二定律等实验均要用到复写纸片和纸带,可所配复写纸片数量 The author self-made teaching aids and reasonable selection of experimental equipment in the teaching practice not only solved the difficulties in high school physics experiments, but also facilitated the students and also saved expenses. Now it is introduced as follows: 1. Self-made carbon paper and tape practice using tick timer Measure the acceleration of uniform linear motion; Verify the conservation of mechanical energy; Validate Newton’s second law and other experiments must use carbon paper and tape, can be equipped with the number of copies
