物理是以实验为基础的学科。在物理教科书中有演示实验、分组实验,还有每章安排的小实验。实验是我们师生最喜欢的一种教与学的方法。其实教师和学生在教与学的过程中开展得更多的还是小实验。我们可以利用日常生活中的常用物品和工具以及从废旧玩具上拆下的零件,自制各种各样简单的仪器,在课堂上、课后、学校甚至在家里开展。因小实验不受时间和地点的限制,在实验整个环节中,学生观察、操作都比较自由,容易触发其创新潜能,带来意想不到的效果。通过多年的物理教学总结,笔者认为小实验的积极开展具有以下的作用。 Physics is based on the experimental discipline. In physics textbooks are demo experiments, group experiments, as well as small experiments arranged by each chapter. Experiments are our favorite way of teaching and learning. In fact, teachers and students in teaching and learning process carried out more or small experiment. We can make all kinds of simple instruments by using the common objects and tools in our daily life and the parts we have removed from the used toys. We can do it in the classroom, after school, at school and even at home. Because small experiments are not limited by time and place, students have more freedom to observe and operate during the entire experiment. They are likely to trigger their innovative potential and bring unexpected results. After years of teaching physics, I believe that the small experiment to actively carry out the following functions.
