某高校临床医学“5+3”专业医学统计学试卷分析

目的 通过分析某高校临床医学“5+3”专业学生《医学统计学》考试试卷，了解学生学习情况，改善试卷质量，为进一步教学改革提供依据。方法 采用教育测量学的原理与方法对试卷的难度、区分度、信度（Cronbach α 系数）和覆盖度及考试成绩进行分析。结果 147 名八年制临床医学学生《医学统计学》试卷的平均成绩为78.25±11.70 分，最低分为42.5 分，最高分为98.5 分，及格率为91.2%；选择题平均得分率85%，名词解释题平均得分率87.2%，填空题平均得分率78%，简答题平均得分率74.1%，计算题平均得分率76.3%；试卷难度系数为0.22，区分度为0.28,；试卷的Cronbach α 系数为0.846，题目间的相关系数＜ 0.2的占89%。结论 本次考试学生成绩优良；试卷难度稍显偏低，总体区分度一般，信度良好，试题覆盖面较广，试卷整体质量优良，能够反映学生掌握知识的水平，今后的教学中应开展多元统计相关知识及统计软件的操作，提高学生的科研素质。

Analysis of the test results of medical statistics in a Qingdao university

Objective To analyze the students' learning situation, improve the quality of the test papers, and provide reference for further teaching reform, all based on the test results of medical statistics in “5+3” program clinical majors.Methods The principles and methods of educational measurement are used to analyze the difficulty, discrimination,reliability (Cronbach α coefficient) and coverage and test scores of the test paper. Results The average test score of 147 “5+3” program medical students was 78.25±11.70, ranged from 42.5 to 98.5, and the passing rate was 91.2%. The average scoring rates for choice questions, terms explanations, fill-in-the-blank questions, short-answer questions, and calculation questions were 85%, 87.2%, 78%, 74.1%, and 76.3%, respectively. The difficulty coefficient of the test paper was 0.22, and the discrimination index was 0.28. The Cronbach α coefficient of the test paper was 0.846, and the correlation coefficient between the questions less than 0.2 accounted for 89%. Conclusion The students in this test had excellent grades; the difficulty of the test paper was slightly lower, the discrimination index was large, the reliability was common, and the test coverage was wide. The quality of this test paper was good, which could reflect the level of knowledge of students. In the future teaching, the operation of multi-statistical knowledge and statistical software should be carried out to improve the scientific research quality of students.
