摘要
针对现有试卷质量评价理论依据不充分、分析指标标准不一,科学性差的特点,结合CTT(classical test theory)真分数不变性、误差安全性及IRT(item response theory)参数不变性、线性等值等优点,提出了一个基于CTT和IRT的试卷质量评价系统的建设思路,并完成系统实现。以某大学五门课程试卷及考生成绩为例,进行了试卷分析和试题分析,分析结果显示,IRT得到的学生能力更贴近实际情况,正确反映了学生能力在该考试中的位置,通过分析结果说明考试排名与学生的客观能力的符合程度,并给出该次考试试卷的改进建议。
Considering the characteristics that inadequate theoretical basis for quality evaluation of the existing papers, the analysis of indicators of different standards, poor science features, combining with the CTF （classical test theory） parameter invariance proper fraction invariance, and error safety and IRT （item response theory） parameter invariance, Linear equivalent advantages, a constructive thought for paper quality evaluation system based on CTT and IRT is put forward and realized. Based on the five course papers and candidates＇ results of a certain university, paper analysis and item analysis are carried out. The analysis results show that the students＇ ability get closer to the actual situation analyzed by IRT, and gives suggestions for improvement of the examination papers.
