实验课教学是一个既熟悉又陌生的课题。近年来物理教学中有的教师是将只要能演示的实验就绝不分组,能以多媒体代替的实验就绝不演示。不少教师还热衷于多媒体课件的研究,创作了不少可以替代实际实验的模拟实验。对学生而言没有了思维障碍,对教师来说减少了处置课堂突发事件的麻烦。但是,正是这几乎完美的过程却体现出实验课教学的不完美之 Experimental teaching is a familiar and unfamiliar topic. In recent years, some teachers in physics teaching will never group as long as they can demonstrate the experiment, and experiments that can substitute multimedia will never show. Many teachers also keen on the multimedia courseware research, created a lot of simulation experiments that can replace the actual experiment. There is no mental retardation for students, reducing the trouble for teachers to deal with unexpected incidents in the classroom. However, it is this almost perfect process that reflects the imperfection of experimental teaching
