在物理教学中适时地运用比较法,对突破教学难点和突出教学重点有着非常重要的作用,能使一些不易直接从理论上理解的问题变得简单而直观。通过比较,可以深刻理解物理概念及规律的内容和本质,有助于知识的记忆、巩固、深化迁移,有助于创造性思维能力的培养。因此,比较法已成为物理教学中的重要逻辑方法之一。 The timely application of comparative law in physics teaching plays an important role in breaking teaching difficulties and highlighting the teaching focus, and can make some problems that are not easily understood directly from the theory become simple and intuitive. By comparison, the content and essence of the concepts and laws of physics can be profoundly understood, which helps to memorize, consolidate and deepen the transfer of knowledge, which is helpful for the cultivation of creative thinking ability. Therefore, comparative law has become one of the important logical methods in physics teaching.
