基于多面Rasch模型的交替传译测试效度验证

A Validating Study on Consecutive Interpreting Test Using Many-facet Rasch Model

本研究对一次交替传译测试结果进行多面Rasch模型检验,从评分标准、评分员、被试和任务4个方面验证了测试的效度,并用偏差分析发现了影响测试结果的因素。检验结果显示:1)所用分项评分标准和任务设计能够显著体现和区分被试口译水平,适合用于口译教学测试的评分;2)评分标准中的"口译技巧与素质"子项对测试结果的整体效度略有影响,可做进一步改善。

Through many-facet Rasch analysis on a consecutive interpreting test,this paper validates the result of the test from four aspects,i.e.rating scale,raters,examinees and tasks.The results show that: 1) this rating scale and task design can effectively reflect and screen examinee's interpreting competence,thus making it suitable for assessing interpreting teaching effect;2) one of the sub-scales,i.e.interpreting skill and interpreter quality,has a slightly nega-tive effect on the overall validity of the test,making further revision on this sub-scale desirable.
