摘要
在命题实践中,一味求新求异,致使试题所考查的知识点超出中学物理范畴,难以达到检测学生核心素养的发展过程与现有水平的目的.以一个考查连接体的经典错题为例,尝试采用微元法、求导法、极坐标法及Origin绘图4种策略厘清连接体中加速度关联情景,剖析该题错误成因,分析相同知识点在高考题中应如何设问,以规避错误的发生.希望引起一线命题者的共鸣,以此促进命题质量的提升.
In proposition practice,blindly seeking novelty and innovation has led to the knowledge points tested in the questions exceeding the scope of high school physics,making it difficult to achieve the goal of testing the development process and existing level of students′core literacy.Taking a classic wrong question about the connection body as an example,this paper tries to adopt four strategies:the infinitesimal method,the derivation method,the polar coordinate method,and Origin drawing,to clarify the acceleration correlation scenario in the connection body,analyze the causes of the wrong question,and analyze how to set questions in the college entrance examination questions with the same knowledge point to avoid the occurrence of wrong questions.It is hoped that it will resonate with the front line question writers and promote the improvement of the quality of question writing.
