高等教育自学考试复本试卷平行性的试后初步评价

The Parallelity of Higher Education Self-taught Examination Papers and Its Post-examination Evaluation

与高等教育自学考试复本试卷平行性有关的因素主要有四类:试卷结构的、题目内容的、题目功能的和结果分数的。复本试卷内容上的平行是试卷平行性的前提与基础,对内容平行的判定主要通过专家判断题目的取样代表性来实现。对复本试卷总体分数的比较主要借助方差齐性检验和平均数差异显著性检验,还可通过雷达图比较同一专业下多个学科的水平变化。题目功能的平行主要借助难度分布和区分结构的比较,多个难度级别分值相差较大表明复本试卷未能满足平行性要求,不同区分功能类型的题目分值较为一致则表明试卷实现了区分功能的平行。

There are four factors which can influence or influence the understanding of the parallelity of higher education self-taught examination papers. They are test construction, item contents, item function and output data. The parallelity of contents is the basis of the whole parallelity of papers, which can be measured by independent experts through the judgment of sample representativeness. The comparison of output data can be achieved through test for homogeneity of variance and T test. It can also be achieved through contrasting the scores of multi-subjects of the same major by means of radar chart. The difficulty distribution and discriminative structure can be used to confirm the item functions to be parallel. If the scores of items within difficulty levels differ significantly between papers, the Darallelitv mav be questioned. While the scores of items within discriminate types are close between papers, the parallelity of item functions can be guaranteed.
