在中学物理教学过程中，我们经常是采用演示实验的方法，来加深学生们对物理现象及基本概念的认识．然而，传统的实验更多地是借助于实物装置进行，而实物装置很难对物理现象的局部和微观加以展现，这无疑将影响学生对概念的理解．随着计算机技术的不断发展，多媒体教学的不断 In the middle school physics teaching process, we often use the demonstration experiment method to deepen students’ understanding of physical phenomena and basic concepts. However, traditional experiments are more often performed with the aid of physical devices. Physical devices, however, can hardly reveal the local and microscopic aspects of physical phenomena. This will undoubtedly affect students’ understanding of concepts. With the continuous development of computer technology, continuous multimedia teaching
