CAT구축을 위한 차별기능문항에 관한 연구

Developing Test Item Banking using Differential Item Functioning for Biomedical Certificate Examinations

  In spite of their demerits the classical methods for item analysis have been used so far without distinct alternatives. However, various innovative item analysis methods using computers were emerging and the analysis methods are still being advanced everyday. In some advanced countries they adopt CAT system in certifying or licensing examinations in the areas of social sciences, natural sciences, engineering and medical sciences. For the CAT executions the test item banking should go side by side with the strict selection of items through the Differential Item Functioning. Since the authors checked the DIF through M-H method and got desirable results, we want to report them here.
