摘　　要：本研究运用多面Rasch测量分析软件FACETS分析了14名有经验的阅卷员在网上和传统方式下批阅20篇作文的评分信度。这些作文从大学英语四、六级考试2002年6月考次上海地区的作文卷中随机抽取。结果显示网上评分信度高于传统评分信度。In this study, FACETS, a many-facet Rasch measurement computer program, was implemented to analyze the data derived from a previous study conducted to explore differences in rater severity and consistency among 14 experienced CET raters in both online and conference marking settings. These raters marked a random sample of 20 compositions written by students studying in universities in Shanghai who took the CET in June 2002. Results indicated that reliability estimates favored the online marking method.
