Rasch 모형을 이용한 교직 적성·인성 검사 도구의 타당화

초록

The purpose of this study is to verify the validity of Teaching Aptitude and Personality Test using Rasch measurement model A; a total of 364 subjects were surveyed. The results showed that the reliability of Teaching Aptitude and Personality Test was high. In addition, the five-point scale of the test tool did function properly. The results of the item analysis showed that the items except for 28, showed a good fit. As a result of the principal component analysis using standardized residuals, it was found that the Rasch model, which assumes the single dimensionality of the test is inappropriate, but according to the test characteristic curve, the data used in this study is appropriate. Based on the results of this study, we proposed some suggestions for future research.
