Analysis on an epidemiology examina tion for medical students of difierent specialties in a military medical university
AIM: To evaluate the teaching results of epidemiology by analyzing the scores of a final epidemiology examination for medical students of different specialties in a military medical university. METHODS: The difficulty, discrimination and reliability coefficient of a final epidemiology examination paper and items were calculated respectively, and the scores of the examination were analyzed. RESULTS: The distribution of the scores displayed a normal distribution, with the mean of 75. 84 and a SD of 6. 90. The range of reliability coefficient of the test items was 0.43 -0.72. The higher difficulty coefficients were found in the multiple choice question items, 50% of which were lower than 0.36. The lower difficulty coefficients were found in the calculating and analyzing question items, which ranged from 0. 69 to 0.91. The lower discrimination coefficients ( <0.20) were found in the multinomial choice items, while the discrimination coefficients for other items were all higher than 0. 40. The parts with the lowest scores were those of retention and application of knowledge. The difficulty coefficients of the test for the 7-year program in clinical medicine, the 5-year program in clinical medicine, the 5-year program in preventive medicine and the 4-year program in public healthcare management were 0.85, 0.80, 0.75 and 0.74 respectively. CONCLUSION: The results of the examination are reliable, for the paper has an appropriate difficulty coefficient, and good discrimination and validity coefficients. To achieve bet- ter teaching results, the course of epidemiology should be offered separately for 7-year program in clinical medicine and 5-year program in clinical medicine on the one hand, and for 5-year program in preventive medicine and 4-year program in public healthcare management on the other.
