描述统计法在外语教学测试中的应用

    The Application of Descriptive Statistical Analysis of Foreign Language Teaching and Testing

    • 摘要: 在日常的教学测试中,教师对学生成绩大多采用平均值和分数段方法进行分析,虽然计算简单、操作方便,但平均值容易受极端数据的影响,且当成绩呈偏态分布时,也无法解释其分布情况,不利于教学信息的发掘和反馈,也影响了教学决策。针对上述传统方法的局限性,本文所提出的描述统计法,将集中趋势、离中趋势、标准分有效地结合起来,对样本定量分析,真实、全面地反映了学生成绩水平,从中找出有利于教学的信息,不断实现衡量标准的科学化。

       

      Abstract: In the traditional way of language testing, teachers usually analyze the scores by calculating the mean and classifying point segments. Though easy to operate, the method of mean calculation is susceptible to extreme data and the classification of point segments cannot tell the distribution of scores when they are abnormally distributed, resulting in the unavailability of positive feedback on teaching from the test. Therefore, this paper proposes the use of Descriptive Statistical Analysis and the Combination of Measures of Central Tendency, Divergence Tendency and Standard Score, which will find out valuable information to enhance the teaching quality.
