物理学中的综合计算是学生最棘手的问题之一, 造成这种现象的原因是:(1) 不能准确的分析物理过程, 理顺已知量与未知量的关系,(2)不能准确、科学、合理地利用隐蔽的条件或物理规律构建方程。物理习题中的一个“图示”、一个“关键词”或一个“数据”都有可能是极其重要的隐蔽方程,而且多数综合题,根本看不出条件与结论的关系,如何让学生尽快熟悉和掌握这方面的技能呢?笔者结合教学的实践,在此作一粗浅的介绍。
The comprehensive calculation in physics is one of the most difficult problems for students. The reasons for this phenomenon are: (1) The physical process cannot be accurately analyzed, and the relationship between the known quantity and the unknown quantity is straightened out. (2) It cannot be accurate. Science and rational use of hidden conditions or physical laws to build equations. A “graphic”, a “keyword” or a “data” in a physical exercise may all be extremely important covert equations, and most comprehensive questions do not show the relationship between conditions and conclusions. How to get students to become familiar with it as soon as possible And master the skills in this area? The author combines the teaching practice, made a rough introduction here.
