Examination paper analysis and evaluation of clinical hematology laboratory technique in four-year medical laboratory specialty / 中华医学教育探索杂志

ABSTRACT

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 corre-lation 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 teaching methods, and finally help further improvement of teaching work.
