ABSTRACT
Objective@#To analyze the quality of final exam papers of Surgery and Field Surgery for five-year medical students from comprehensive class of Grade 2014, so as to check the mastery of different students, perfect the construction of item banking, verify the quality of teaching and learning, and thus provide references to further teaching reform.@*Methods@#SPSS 21.0 was used for statistical analysis of 133 Surgery and Field Surgery papers of students from comprehensive class of Grade 2014.@*Results@#The highest score was 93.5, the lowest score was 52.0, and the average score was (70.60±9.00). Among those 133 students, six students were failed, occupying 4.51%. The overall difficulty coefficient of examination paper (P) was 0.71, and P value of multiple choice questions and blank-filling questions was 0.4-0.7. Difference degrees (D) of question types were more than 0.600 and the overall reliability was 0.764. Scores of examination paper were generally in normal distribution. The average scores of students form anesthesiology major were higher than those of students from navigation medicine major, but the average scores of students from above two majors were higher than those of students from psychology major, with statistically significant differences (P<0.05).@*Conclusion@#Question types of this paper are comprehensive and reasonable. The overall difficulty is not high, the difference degree is good, the reliability is good and the score distribution is reasonable. However, the question should be further improved, focusing on the reasonable distribution of difficulty of question. In addition, we should strengthen the teaching of the course in students from psychology major.

Objective To analyze the quality of final exam papers of Surgery and Field Surgery for five-year medical students from comprehensive class of Grade 2014, so as to check the mastery of different students, perfect the construction of item banking, verify the quality of teaching and learning, and thus provide references to further teaching reform. Methods SPSS 21.0 was used for statistical analysis of 133 Surgery and Field Surgery papers of students from comprehensive class of Grade 2014. Results The highest score was 93.5, the lowest score was 52.0, and the average score was (70.60 ±9.00). Among those 133 students, six students were failed, occupying 4.51％. The overall difficulty coefficient of examination paper (P) was 0.71, and P value of multiple choice questions and blank-filling questions was 0.4-0.7. Difference degrees (D) of question types were more than 0.600 and the overall reliability was 0.764. Scores of examination paper were generally in normal distribution. The average scores of students form anesthesiology major were higher than those of students from navigation medicine major, but the average scores of students from above two majors were higher than those of students from psychology major, with statistically significant differences (P<0.05). Conclusion Question types of this paper are comprehensive and reasonable. The overall difficulty is not high, the difference degree is good, the reliability is good and the score distribution is reasonable. However, the question should be further improved, focusing on the reasonable distribution of difficulty of question . In addition , we should strengthen the teaching of the course in students from psychology major.
ABSTRACT
Objective To explore the application and evaluation of S-P chart in analyzing examination papers of nutrition and food hygiene and improve the quality of examination.Methods 15 papers were randomly selected from 56 examination papers of nutrition and food hygiene and 5,4,5,1,0 were randomly selected from the students with scores of ＜60,60-69,70-79,80-89,and 90-100 with stratified samplingmethod.S-P chart and fuzzy S-P chart were drawn according to objective and subjective questions.Results In the S-P chart of multiple choice,both the P-curve and S-curve were in the lower right corner.There was no obvious fault on the S-curve,while P-curve had obvious faults.There were 2 questions and 1 student with alarm coefficient ＞ 0.75.The difference,difficulty coefficient,stability coefficient and suitability coefficient were 0.13,0.66,0.55 and 0.58 respectively.In the S-P chart of multiple choices,both the P-curve and S-curve were in the upper left corner.There was no obvious fault on the S-curve,while P-curve had obvious faults.There were 1 question and 1 student with alarm coefficient ＞ 0.75.The difference,difficulty coefficient,stability coefficient and suitability coefficient were 0.10,0.30,0.64 and 0.60 respectively.In the S-P chart of subjective questions,the difference was 0.275,and both the P-curve and S-curve were in the upper left corner and had no obvious fault.Conclusion The application of S-P chart can help teachers to analyze the difference between the quality of test questions and the grade of students,thereby making teaching more targeted and improving the quality of teaching and examination.
ABSTRACT
Objective Based on the objective test (A type) results of the 2014 comprehensive clinical course graduation test of 3+2 assistant general practitioners training,this article analyzed the differences between different teaching units,so as to provide objective basis for improving the teaching level of each unit.Method We established a database with EXCEL 2000,and put each question's ID and points,and the score of each student into the computer,so we could get the difficulty coefficient,distinction degree and reliability of the test paper,and calculate the difficulty coefficient and difference of each question.Then we analyzed the difficulty coefficient,the difference and the reliability of the 122 students' testing results,and compared the accuracy to the same question of the 6 teaching units.Result The objective test's (A type) difficulty coefficient is 0.77,distinction degree is 0.19,and reliability is 0.99.The highest score of the 122 students is 47 points,and the lowest score is 28 points,the average score is (38.5 ± 3.9) points.In the 50 questions,3 questions' difficulty coefficient is less than 0.4,14 questions' difficulty coefficient is between 0.4-0.7,33 questions' difficulty coefficient is above 0.7,so the difficulty degree of the paper is relatively low.In the 50 questions,23 questions' distinction degree is less than 0.15,17 questions' distinction degree is between 0.15-0.30,10 questions' distinction degree is above 0.30,so the distinction degree of the paper is relatively high.In the 50 questions,20 questions' accuracy appears larger differences between each unit:9 questions' accuracy has decreased significantly among 1-2 units,4 questions' accuracy decreased significantly among 3 units,3 questions' accuracy decreased significantly among 4 units,only 1 unit has high accuracy among 2 questions,and 2 questions' accuracy decreased significantly among all units.These problems are related to the teachers' teaching ability,the difficulty in mastering the key points of the curriculum,the lack of the concept of the general practitioners training.Conclusion The design of the examination paper is basically in line with the study purpose and the objectives of the training course.This examination paper was highly reliable,and suitable for the professional theory and ability test.There are site differences between each unit,which can provide an objective basis for improving the teaching level of different teaching unit,and we will solve the problems in the form of collective preparation next step.
ABSTRACT
Objective: In order to sum up the teaching experience and improve the teaching quality.Methods: The human anatomy final examination papers for the students of 2007 majoring in clinical medicine were analysed.Results: The averaged 83.87,showed an appropriate degree of difficulty and discrimination of the examination paper and reasonable scores with negative skew distribution.Conclusions: This analysis as an objective index can be used to evaluate the response of teaching in human anatomy as well as improve the quality of test paper.
