中学物理实验的作用是什么?新物理教学大纲已明确指出,是“能够使学生理解物理概念和规律的建立与实验的关系,培养学生一定的实验能力。”并且“对于培养学生学习物理的兴趣也是十分重要的。”然而怎样使物理实验教学达到上述效果还需我们下功夫探索。在教学中有时会遇到这样的情形,由于课前准备不足,上课时演示现象出不来,或者虽动了一点但极不明显。于是教师手忙脚乱,满头大汗,语言缺乏伦次。学生则垂头丧气,索然无味,实验走了过 What is the role of the middle school physics experiment? The new physics syllabus has clearly stated that it is “can enable students to understand the relationship between the establishment of physical concepts and laws and experiments, training students a certain degree of experimental ability.” and “for students to learn The interest in physics is also very important.”However, how to make physics experiment teaching achieve the above-mentioned effect requires us to make great efforts to explore. In the teaching sometimes encountered such a situation, due to insufficient preparation before class, the demonstration phenomenon can not come out in class, or even though a little but very obvious. So the teachers scrambled and sweated and the language was lacking. The student is dejected, uninteresting, and experiment passed
