摘要 计算机自动评分(CAS)在大规模考试主观题评分中的应用,能够有效提高考试评分效率与客观性。在本研究中计算机自动评分技术首次被引入自学考试领域,用于本科阶段外语类课程《综合英语(四)》的主观题评分。通过对72名考生的主观题自动评分与人工评分数据进行相关分析及配对样本t检验,发现主观题的自动评分与人工评分高度相关,主观题总分的自动评分与人工评分无显著差异,总体而言本次《综合英语(四)》考试的主观题自动评分是可靠的。 Computer-automated Scoring (CAS for short), is applied to large-scale tests for subjective items' scoring, which promotes test scoring efficiency and objectivity. In this article CAS is brought into English testing in Self-taught examinations for the first time and used for subjective items' scoring in Comprehensive English IV. In this study we adopted Pearson Correlation and Paired-Samples T-Test to analyze the scoring data (automated vs. manual) of 72 examinees. The result shows that automated scoring has got significantly high correlation with manual scoring, subjective items' total scores of automated scoring and manual scoring have got no significant mean difference. In general computer-automated scoring of subjective items in Comprehensive English IV is statistically reliable.
