Abstract

The purpose of this study is to examine the number of DIF items detected by HGLM at different sample sizes. Eight different sized data files have been composed. The population of the study is 798307 students who had taken the 2006 OKS Examination. 10727 students of 798307 are chosen by random sampling method as the sample of the study. Turkish, science, and social studies subtests, all composed of 25 items and applied in the OKS-2006, are used as data gathering instruments in this study. It has been concluded that varieties in sample sizes have a great effect on DIF detection in test items.

Özet

Bu çalışmanın amacı, farklı örneklem büyüklüklerinde Maddenin Farklı Fonksiyonlaşmasında (MFF'nin belirlenmesinde) kullanılan yöntemlerden Genelleştirilmiş Aşamalı Doğrusal Modelleme (GADM) ile belirlenen MFF'li madde sayılarının incelenmesidir. Araştırmanın amacı farklı örneklem büyüklüklerinde GADM ile elde edilen MFF'li madde sayılarındaki değişkenliği gözlemek olduğundan sekiz farklı büyüklükte veri dosyaları oluşturulmuştur. Araştırmanın evrenini 2006 OKS' ye giren 798307 öğrenci; örneklemini de bu evrenden tesadüfi örnekleme yöntemi ile seçilen 10727 öğrenci temsil etmektedir. OKS-2006 yılında uygulanmış olan 25'er maddelik Türkçe, Fen Bilgisi ve Sosyal Bilgiler alt testleri veri toplama aracı olarak ele alınmıştır. Bu çalışmada, örneklem büyüklüklerindeki değişkenliğin test maddelerinde MFF belirlemede önemli bir etkisinin olduğu ortaya çıkmıştır.
