ABSTRACT
Objective To explore a reasonable,accuracy and effectual proposition model for medical imaging examination.Methods Mean scores and their standard deviation and distribution as well as the difficulty,discrimination,reliability and validity of the test paper were analyzed for the 2005 grade 7-year program students by using SPSS 13.0 statistic software.Results The scores of the 67 copies of test paper displayed a normal distribution,with the mean score of 73.76 and standard deviation of 11.88.The difficulty,reliability and validity indexes of the test paper were 0.74,0.78 and 0.25 respectively.The difficulty,discrimination,reliability and validity indexes of subjective items were higher than those of objective items(0.76 vs.0.73,0.94 vs.0.90,0.71 vs.0.68,0.32 vs.0.22,respectively).Conclusions We should keep quite high proportion of subjective items and make detailed scoring standard in medical imaging examination.Furthermore,as a supplement,objectively items such as multiple choice questions can expand the scope of knowledge examined.
