Klasik Test Kuramı’na ve Madde Tepki Kuramı’na Dayalı Test Eşitleme Yöntemlerinin Karşılaştırılması

This study aims to decide the equating method with the least equating error by using the equating methods in Classical Test Theory and Item Response Theory. In this study, booklet 1 and booklet 3 data were used for PISA 2012 Mathematics test. For this study, data from Turkey, Indonesia, Shanghai/China and Finland countries participating in PISA 2012 were selected. Linear equating methods (Tucker (w1=1, w1=0.5), Levine observed score (w1=1, w1=0.5), Levine true score, Classical Congeneric and Braun-Holland), equipercentile equating methods (pre smoothing according to C6 polynomial degree, beta4, post smoothing according to S 0.05 cubic function, frequency estimation (w1=1, w1=0.5)) were used in the study. In Classical Test Theory, the least error is obtained from the frequency estimation method with a synthetic universe weight of w1 = 0.5. For the Item Response Theory, the calibration method was first decided and this method is the Stocking-Lord method. In Item Response Theory, it was decided that the true and observed equating methods were equated with the least errors in the IRT true score equating method. When the theories are compared, the actual score equating method based on the IRT method is the recommended equating method with the least equating errors.
