课程论文评分中的主题偏倚分析方法研究

An analytical method for topic bias in course paper grading

课程论文评分往往主观性较强,教师在对课程论文进行评分时可能因对特定主题的论文存在偏倚而在评分中引入偏差,导致论文评分不能准确反映学生的真实水平。本文以《临床药理学》课程论文评分结果为实例,对检验课程论文评分结果中是否包含主题偏倚的分析方法进行了探讨。通过计算纵向偏倚因子和横向偏倚因子,比较了同一教师对不同主题的论文和不同教师对同一主题的论文评分上的差异,构建了一种科学、易行的分析方法。该方法可帮助教师快速发现课程论文评分中是否隐含相关偏差,从而使课程论文评分更加客观准确。

Course paper grading often involves subjective factors.Teachers may introduce biases into the grading due to their preferences for certain topics,resulting in inaccurate grading results that fail to reflect the true abilities of students.Taking the grading results of the"Clinical Pharmacology"course as an example,this article investigates the analytical method for detecting topic bias in the course paper grading.A comparative analysis was performed on the differences in the scores between different topics graded by the same teacher and between the same topic graded by different teachers by calculating the vertical bias factor and the horizontal bias factor,and a scientific and feasible analytical method was established.This method can help teachers quickly discover biases in their course paper grading,thereby making the grading more objective and accurate.
