九年义务教育教科书《物理》中编排了较多的实验,这些实验从各个方面加强了对学生基础知识的夯实和基本技能的训练.其中有一些疑难实验,由于实验要点不易把握,容易失败而常被放弃,实验要点的把握已经成为制约实验成功的瓶颈.针对这个问题,笔者对教材中的几个疑难实验进行了分析、总结,提 Nine-year compulsory education textbook “Physics” has organized many experiments. These experiments have strengthened the basic knowledge of students and training of basic skills from various aspects. There are some difficult experiments, which are difficult to grasp because of the experimental points and are easy to fail. Often given up, the grasp of experimental points has become a bottleneck restricting the success of the experiment. In response to this problem, the author analyzed and summarized several difficult experiments in the teaching materials.
