摘要
"趋中评分"指在作文评分等主观性评价过程中,评分员较少给出高分或低分,分数多集中在评分量表中间段的现象。趋中评分是一种系统性的评分误差,它对考试质量有较大影响。本研究分析了主观性试题网上评阅中的趋中评分现象,归纳出三种趋中评分类型,分析了趋中评分的成因,认为趋中评分可以通过校验卷法和统计指标法进行判定,在考试研发和评阅阶段可在多个方面、结合技术和非技术的手段进行控制。
Researchers find that in scoring process of subjective test items such as composition scoring, some raters tend to assign central scores, avoiding using the high or low end of the rating scale. This is called ＂central rating＂. Central rating belongs to systematic scoring errors which will cause deterioration of test quality. This paper analyzes central rating in net-based scoring of subjective test items. It suggests three types of central rating and analyzes causes of central rating. Central rating can be detected by two methods, which are anchor paper method and statistic index method. All through the test development and scoring process, multiple measures should be applied to control central rating.
