分析性英语口语测试评分标准的研究

基于多层面Rasch模型,研究分析某省随机抽样高中考生短文朗读和自由交谈两种口语考试任务的评分维度及量表的使用情况。结果表明,短文朗读任务和自由交谈任务的评分维度设置均较合理,能够较准确地反映考生的能力,但是短文朗读量表的等级之间存在非等距性问题,自由交谈任务评分维度中"交际策略"与其他三个维度存在显著差异。这些信息对于修改和完善评分量表及相关维度具有重要意义。

The fitness of rating dimension setting and scale distribution of two oral English tasks were analyzed based on Many- facet Rasch Model. The results showed that the rating dimensions of the two tasks were appropriate and the students＇ abilities could be effectivly measured. However,the points on the scales were not evenly spaced in the task of reading aloud and there was significant difference between the dimension of communicative strategy and three other dimensions with regards the task of free talk.
