人教版高中《物理》第二册(必修加选修)第十章“机械波”中,新增加了“多普勒效应”这一节内容.现就本节内容教学中存在的一些常见问题,笔者与同仁提出讨论,供参考.一、物理教学中已经存在的问题高中物理新教材(已审定)的正式使用已有三年多的时间,在物理教学中已经存在的问题,除一些个别新出版的教学资料、书籍没将“多普勒效应”列入其中外,大部分资料不但要求进行“频变”的定量计算,而且经常出现不正确的知识概念.如在一套《高中物理新教材同步练习》的资料中,有这样一道题目:已知
People PEP version of high school “Physics” second volumes (compulsory optional) the tenth chapter “mechanical wave ”, the new added “Doppler effect ” this section is now the contents of this section teaching exists Some common problems, the author and colleagues to discuss for reference.A, the existing problems in physics teaching The new high school physics teaching (validated) the official use of more than three years, the existing problems in physics teaching, in addition to Some of the newly published teaching materials and books do not include the Doppler effect, and most of the information requires not only quantitative calculations of frequency-dependent variations but also often incorrect concepts of knowledge. In a set of “high school physics teaching new material synchronous practice” information, there is such a topic: Known
