从事中学物理教学的教师都会有这样的一个同感:学生在准确表达物理概念、叙述物理规律、说明实验现象和准确书写物理名词方面存在困难。口头回答问题时不能兼顾准确性、系统性和科学性,往往顾此失彼、漏洞百出。我们在不断地在同行中交流这些同感的时候,是否思考过是什么原因让学生 Teachers who engage in middle school physics teaching share this sympathy: Students have difficulties in accurately expressing physical concepts, describing physical laws, explaining experimental phenomena, and accurately writing physical nouns. When answering questions verbally, they cannot take account of accuracy, systematization, and science. They often miss out on each other and suffer from loopholes. When we constantly exchanged these sympathies with our peers, did we think about the reasons for students?
