Objective To explore the influence of the selecting questions from national question database on the Pediatrics theoretical examination of clinical undergraduates under the mode of teaching-examination separation. Methods to make an overall quantitative analysis of 304 test papers, selecting questions from national question database for the final pediatrics theoretical examination in the first term from 2017 to 2018, which was answered by two classes of clinical medicine students enrolled in 2014. Results From the distribution of these two classes' scores, it can seen that the frequency distribution on both sides of the average is relatively symmetrical and all of them presented normal distribution, but they are all below average and good grades are fewer. They account for 5.29% and 9.15% of the total number respectively in each class. The number of students who failed of the two classes accounts for 20.53% and 16.99% respectively. The difficulty coefficients of the total volume are respectively 0.67 and 0.69, whose overall difficulty is moderate. Moreover, the test reliability coefficients of two classes are 0.764 0 and 0.768 9 respectively. The discrimination of the total volume of these two classes are all 0.22. There are some errors for the examination papers including in multiple choice options, repetitive questions, too many ques-tions in circulatory system and questions above student current levels. Conclusion The result indicates that the testing questions show the difference of the students' ability and the reliability of the test through the overall quantitative analysis of the test. However, relatively low scores and a relatively large number of students failing the test indicate that students just stay in the old teaching and testing mode and they only master classroom knowledge. Therefore, they do not do self-learning well. Separation of teaching and testing could help to cultivate students' self-learning ability. At the same time, the quality of examination questions of the national question database and group questions should be constantly improved, which is the premise to ensure the objective reflection of students' learning ability.
Résumé
OBJECTIVE: To evaluate the ability of health emergency drill for sudden poisoning incidents in Guangdong Province. METHODS: A double-blinded method was used to organize 22 teams in Guangdong Province to conduct a health emergency drill which contained preliminary and repeated drill. The preliminaries contained blind sample analysis,theoretical examination and skills assessment. The repeated drills was desktop network exercise carried out for the teams ranked top 10 in the preliminaries. RESULTS: In the preliminary round,the median( M) of total score among the 22 teams was 72. 5. Among them,blind sample analysis,theoretical examination and skills assessment were 71. 0,61. 4 and 76. 5,respectively. The total score of skill assessment was higher than that of theoretical assessment( P < 0. 05). The passing rate of 22 teams was 68. 2%(15/22),and the failure rate was 31. 8%(7/22). The failing teams all came from the nonPearl River Delta region. The total preliminary scores,passing rate,the total scores of blind sample analysis and skills assessment of the teams in Pearl River Delta Region were higher than that in the non-Pearl River Delta region( P < 0. 01).In the theoretical examination,the scores of detection and investigation were both higher than that of medical rescue( P <0. 05). For the skills assessment,the scores of decision-making,personal protection and poisoning detection were in the top three,the scores of the medical rescue and investigation were relatively low( P < 0. 05). In the repeated round,the M of desktop exercise was 55. 0,passing rate was 20. 0%,and the failure rate was 80. 0%. CONCLUSION: The health emergency response capacity for sudden poisoning incidents in Guangdong Province needs to be improved. The construction of emergency response capacity for emergency poisoning in the non-Pearl River Delta region should be strengthened,especially the training on strengthening theoretical and practical knowledge of poisoning medical treatment and poisoning investigation.
