现行客观性外语测试题评分的缺陷主要表现在:对不同考查任务的赋分差异充满主观偏向,对同一考查任务中的各个小题进行平等赋分难以反映各个小题对外语能力的不同要求,造成这两方面问题的根源在于评分没有反映不同的试题对有不同的外语能力要求。为了纠正客观外语测试题的评分缺陷,本研究尝试提出基于难度系数的动态评分设想:首先根据考生的答题情况,计算出各题的难度系数;接着根据各个小题的难度系数,对其进行赋分,作为评分标准,称作基于难度系数的赋分;根据难度系数赋分,统计考生的原始分;最后,把考生的原始分转换成符合接受习惯的T分数。这种评分方法不是基于测试设计者的预设标准,而是基于不同考生群体的具体表现,随考生群体情况的变动而变动,所以叫动态评分。为了更详细地解释这种评分方法,本文还进行了实例演示。
The defects of the current objective test questions in foreign language test are mainly manifested in that: the sub-bias of different test tasks is full of subjective bias, and it is difficult to reflect the different requirements of each small topic on foreign language ability by equally giving equal emphasis to each small question in the same test task. The root cause of these two problems is that the score does not reflect the different requirements of the foreign language proficiency test. In order to correct the scoring defects of objective foreign language test questions, this study attempts to propose a dynamic score assumptions based on the difficulty coefficient: First, according to the candidates’ questions, calculate the difficulty coefficient of each question; Then according to the difficulty coefficient of each small topic, Points, as the grading criteria, are referred to as points based on the degree of difficulty; points are given based on the degree of difficulty, the original points of the candidates are counted; and finally, the candidates’ original points are converted into T-scores that match the accepted habits. This scoring method is not based on the test designer’s default criteria, but based on the specific performance of different candidates groups, with the changes in the group of candidates changes, so called dynamic score. In order to explain this scoring method in more detail, this article also gives an example demonstration.
