四年制医学检验专业《临床血液学检验技术》试卷分析与评价

Examination paper analysis and evaluation of clinical hematology laboratory technique in four-year medical laboratory specialty

目的评估临床血液学检验技术试卷质量，探讨教学方法，以期提升课程质量。方法调取中国医科大学2014级第一届四年制医学检验专业临床血液学检验技术理论试卷和实验试卷各27份．采用SPSS19．0对试卷分数的分布频数和均数进行统计，应用相关函数公式分别计算各类型试题难度和区分度。根据分数分布评价学生知识掌握情况，根据试题的难度和区分度进行试卷质量分析。结果理论试卷平均成绩为（76．81±9．12）分，命题方案合理，总体难度为0．78，区分度为0．41；实验试卷平均成绩为（14．33±1．21）分，总体难度为0．72，区分度为0．10。结论理论试卷难度适中，具有良好的区分能力；实验试卷难度适中，但区分度较差。应借鉴ISO15189先进管理理念，结合四年制医学检验专业培养要求，强化学生灵活运用理论知识的能力，进一步完善实验考核机制、改进实验教学方法。

Objective To assess quality of the clinical hematology laboratory technique examination papers and to explore the teaching methods, in order to improve the quality of the course. Methods After gathering 27 clinical hematology laboratory technique theoretical and experimental papers of the first session four-year laboratory medicine students in China Medical University of Grade 2014, we adopted the method of SPSS 19.0 on test scores for statistics of distribution frequency and mean, and applied the correlation function formula to calculate the difficulty and discrimination of various types of test questions, and then evaluated the level of knowledge according to the score distribution, and analyzed the quality of the papers based on the difficulty and discrimination. Results The average score of theoretical papers was （76.81± 9.12） points, the proposition scheme is reasonable, the overall difficulty was 0.78, and the discrimi- nation is 0.41. The average score of experimental papers was （14.33 ± 1.21） points, the overall difficulty is 0.72, and the discrimination is 0.10. Conclusion The difficulty of the theoretical papers is moderate, equipped with better capacity to discrimination, the difficulty of the experimental papers is also moderate, otherwise with poor discriminatory ability. We should learn from advanced management concept of ISO 15189 and combining professional training requirements of the four-year laboratory medicine, and strengthen students＇ ability of using theoretical knowledge flexibly to further perfect the mechanism of the experimental exam, improve experimental teaehing methods, and finally help further improvement of teaching work.
