2005年度上半年PETS三级考试作文评分效度研究

Study on the Scoring Validity of Essays in PETS 3 in 1995

对2005年3月份PETS三级考试的作文语料进行了大规模的抽样调查,运用定性和定量相结合的方法研究了PETS三级考试作文评分效度.结果显示:虽然2005年3月份PETS三级考试的作文原始分与多人再评的参照分数相关,但原始分与多人再评的平均分之间存在统计上的显著性差异;该作文考试的题目说明没有详细、清晰地说明写作程序及评分方法,导致部分考生不能准确把握写作内容.

The compositions in PETS 3 in March, 2005 were sampled, and the scoring validity in terms of raters for compositions in PETS 3 was tested with quantitative and qualitative methods. The results show that： although original ratings and standardized ratings in 2005 are correlated, their average scores are significantly different; the writing specification in this test could not show the writing procedures and scoring methods accurately, which results in that some examinees could not write accurately.
