新课程改革下高考物理选做题目等值性研究——以重庆物理高考试题结构为例

The Equivalence Study of Physical Selected Questions in College Entrance Examination under the New Curriculum Reform:Take the Structure of Chongqing Physical College Entrance Examination as an Example

我国高中新课程改革物理学科分为必修4个模块(物理1,物理2,3-1和3-2)和选修4个模块(3-3,3-4,3-5和2-2)内容。在高考中,针对选修模块,国家课程标准卷和某些省市自主命题的试卷出现了选做题型,即不同的考试人群可以选择不同的试题作答以获取相应的分数,这必然引起试题得分的非等值性。研究以重庆市物理高考试题结构为例,通过百分位等值和线性等值法研究物理高考中选做题目的等值问题,得出选做题目分数不等值的定量结果,并提出修正选做试题不等值的方法,为更好实现物理高考中选做试题的公平性提供一种科学的判断依据。

Senior high school physics course is divided into 4 required modules （physicsl ,physics2,3-1 and 3-2） and 4 elective mod ules（3-3,3-4,3-5 and 2-2） content under the new curriculum reform. In the entrance examination, for elective module, the national curriculum standard paper and some independent proposition provinces appeared optional questions. This means that different exam- inations crowd can choose different questions to answer in order to ohtain the corresponding score, which would inevitahly lead to non-equivalence of the exam score. In this paper, taking Chongqing physical college entrance examination structure as an example, through the percentile equivalent and linear equivalent method we study the equivalence of optional questions, and get the scores non- equivalent quantitative resu~,ts of selected questions and propose amendments optional questions non-equivalent method. That would provide a scientific judgement to implement optional questions fairness to the physics college entrance examination.
