임상병리 시험의 IRT-CAT 실시 구축에 관한 연구

Developing of Test Item Bank for Biomedical Laboratory Sciences Certificates Using IRT

  The license examinations for health and medical fields have been developed. the classical item analysis, however, has been used the test system and most of the tests are paper and pencil test so far. The relative difficulty of the tests depend on intellectual levels of candidates and few solutions for the changes of the relative difficulty of the test often lead to various test contingences. The IRT was a logic theory for the CAT. The data for relative difficulty, discrimination, guessing parameter were calculated by IRT and Item Banking was made from the calculated data. Through the study we have finally confirmed that the big step program has its ability to check the validities of items from preparing or scoring to item analysis.
