Abstract

BACKGROUND

Pathophysiology, a bridge between basic and clinical medicine, is particularly crucial for dental students. This article analyzes the final pathophysiology examination paper for the 2021 grade dental medicine students at Xi'an Jiaotong University to understand the students' knowledge mastery, assess teaching effectiveness, and ultimately improve teaching quality.

METHODS

The theoretical examination results of 93 dental medicine students from the 2021 grade were analyzed and graded using the Optical Mark Recognition digital grading system to ensure accuracy and efficiency in processing multiple-choice responses. Statistical analyses were conducted using SPSS 26.0 to determine the score distribution, difficulty index, discrimination index, and reliability.

RESULTS

The examination scores of the 93 dental medicine students showed a skewed distribution, with an average score of 74.32, a median of 76, and a standard deviation of 17.31. The pass rate was 83.87%. The detailed score distribution was as follows: 23.66% of students scored between 90 and 100, 18.28% scored between 80 and 89, 22.58% scored between 70 and 79, 19.35% scored between 60 and 69, and 16.13% scored below 60. The Kolmogorov-Smirnov (K-S) test confirmed a significant deviation from normality (K-S value = 0.1477, P < 0.0001), with a skewness coefficient of -0.75 and a kurtosis coefficient of 0.45. The overall difficulty index of the exam was 0.73, the discrimination index was 0.42, and the reliability was high at 0.86.

CONCLUSIONS

Our data suggest that the examination demonstrated high reliability and acceptable discrimination but was relatively easy. Future examinations should increase the difficulty level and discrimination appropriately. In teaching, we should continue to enhance teaching quality by focusing on key knowledge points, optimizing the assessment system, exploring innovative teaching modes, and further improving overall teaching quality.

摘要

背景

病理生理学作为基础医学与临床医学之间的桥梁，对口腔医学生尤为重要。本文分析了西安交通大学2021级口腔医学专业学生的病理生理学期末考试试卷，以了解学生的知识掌握情况，评估教学效果，最终提高教学质量。

方法

分析了2021级93名口腔医学专业学生的理论考试成绩，并使用光学标记识别数字评分系统进行评分，以确保处理多项选择题答案时的准确性和效率。使用SPSS 26.0进行统计分析，以确定分数分布、难度指数、区分度指数和信度。

结果

93名口腔医学专业学生的考试成绩呈偏态分布，平均分为74.32，中位数为76，标准差为17.31。及格率为83.87%。具体分数分布如下：23.66%的学生成绩在90至100分之间，18.28%的学生成绩在80至89分之间，22.58%的学生成绩在70至79分之间，19.35%的学生成绩在60至69分之间，16.13%的学生成绩低于60分。Kolmogorov-Smirnov（K-S）检验证实显著偏离正态分布（K-S值 = 0.1477，P < 0.0001），偏度系数为 -0.75，峰度系数为0.45。考试的总体难度指数为0.73，区分度指数为0.42，信度较高，为0.86。
