2013年上海高考物理试卷第20题,问题情境与生产作业过程和中学教学实际产生明显冲突,导致在不同认知和分析的情况下,出现不同的答案.关于该题讨论的多篇文章刊载于中学物理主流期刊,该题也被多本主流教学资料选用,给出的两组答案也各不相同,给中学物理教学带来诸多困难.本文对这两组答案进行比较分析,并据此建议该题应该淡出中学教学实际.
There was a clear conflict between the problem situation and the production process and the teaching practice in middle school in 2013 Question 20 of the Shanghai college entrance examination physics exam, leading to different answers under different cognitive and analytical situations. Many articles on this topic are published in Middle School Physics mainstream journals, the subject has also been selected by the number of mainstream teaching materials, given two sets of answers are also different, to the physics teaching in secondary schools to bring many difficulties.This paper comparative analysis of these two sets of answers, and accordingly recommended The title should fade out of high school teaching practice.
