解题中易错的一类物理问题的分析

Analysis on a Kind of Physics Problems in Which Students Are Likely to Make Mistakes When Solving Them

解题是大学物理学习中的重要一环。学生解题出错并不可怕，关键是要重视、找出并认识产生错误的原因。解题出错的原因多种多样，但有一类错误具有一定的共性，这就是由于随意使用过去所学的一些物理经验知识而导致的错误，且这类错误学生自己往往还不容易发现。本文列举了与此类错误有关的若干例题，逐一加以具体的分析、说明，并提出了物理教师在《大学物理》教学中应重视运用的教学方法。

Solving problems is an important link in the study of college physics. It doesn't matter that students make mistakes in solving problems, the important thing is to pay much attention to, find and know the causes leading to mistakes.The causes of making mistakes are varied. But there is a kind of mistakes having a certain common property, that are the mistakes caused by carelessly applying some experiential knowledge in physics learned before, and students often fail to find this kind of mistakes themselves. This paper shows some examples related with this kind of mistakes, concretely analyses and explains them one by one, and puts forward some teaching methods that physics teachers should pay much attention to using in the teaching of College Physics.
