2002, 2003년도 의사국가시험에서 확장결합형 문항의 양호도 평가

Abstract

Purpose: In 2002, extended-matching type (R-type) items were introduced to the Korean Medical Licensing Examination. To evaluate the usability of R-type items, the results of the Korean Medical Licensing Examination in 2002 and 2003 were analyzed based on item types and knowledge levels. Methods: Item parameters, such as difficulty and discrimination indexes, were calculated using the classical test theory. The item parameters were compared across three item types and three knowledge levels. Results: The values of R-type item parameters were higher than those of A- or K-type items. There was no significant difference in item parameters according to knowledge level, including recall, interpretation, and problem solving. The reliability of R-type items exceeded 0.99. With the R-type, an increasing number in correct answers was associated with a decreasing difficulty index. Conclusion: The introduction of R-type items is favorable from the perspective of item parameters. However, an increase in the number of correct answers in pick 'n' type questions results in the items being more difficult to solve.
