摘要
讨论两种已有的成卷模型的试卷不可直接使用的原因,分析经典测验理论下的试题库系统的指标体系、指标取值和成卷要求的特点,通过将主观的特殊要求转化为评价函数,提出了一个改进的成卷模型。该模型不仅具有更强的通用性,而且大大改善了成卷结果的质量、提高了试卷的可用性。
Discusses the reason why two kinds of present test paper creating model can＇t be used directly, analyzes the index system, index value and test paper creating requirement of test paper database system in classical test theory. Presents an improved test paper creating model by using subjective special requirement transferred estimating function. The model not only has stronger common properties, but also improves the quality and usability of test paper output.
