贵刊1997年第1期《命题失误探究》(以下简称《命文》)一文,对当前中学物理命题中出现的一些失误作了较为详细的分析.作为一个合格的物理教师应该在命题中避免出现这些错误.但据笔者观察,《命文》中的个别错题在部分地区不但未得到纠正,反而有人将其作为妙题传播,因此有必要从理论上深入探究这些错题.下面将对《命文》中例3详细分析.
The first issue of Propositional Mistakes Inquiry (herein referred to as “Ming Wen”) in your first issue of 1997 is a detailed analysis of some mistakes that appear in the current middle school physics propositions. As a qualified physics teacher, you should avoid the propositions. These mistakes have occurred. However, according to the author’s observation, some of the wrong questions in “Ming Wen” have not been corrected in some areas. Instead, they have been spread as miracles. Therefore, it is necessary to inquire into these wrong questions theoretically. A detailed analysis of Example 3 in “Meng Wen”.
