Çoktan Seçmeli Testlerde Kategorili ve Önsel Ağırlıklı Puanlamanın Diferansiyel Madde Fonksiyonuna Etkisi ile İlgili Bir Araştırma

Bu araştırmanın amacı, iki kategorili ve önsel ağırlıklı puanlama yöntemleri kullanılarak puanlanan bir testte, cinsiyet grupları ve okul türüne göre diferansiyel madde fonksiyonunu ortaya koymaktır. Çeşitli illerdeki 7'si özel, 8'i devlet okulu olmak üzere 15 ilköğretim okulundan seçilen 780'i erkek, 698'i kız öğrenciden elde edilen madde puanları, MH test istatistiği ile DMH katsayısına ve lojistik regresyon modeline göre analiz edilmiştir. Hem okul türü hem de cinsiyet bakımından maddelerin çoğunda göz ardı edilebilir düzeyde DMF olduğu, bir maddede ise okul türü bakımından özel okullarda okuyan öğrenciler lehine, cinsiyet bakımından da erkek öğrenciler lehine DMF ortaya çıktığı belirlenmiştir.

The Effects of Binary and Priori Weighted Scoring on the Differential Item Functioning Multiple Choice Tests

The purpose of this study is to determine the differential item functioning of a test scored via binary and priori weighting scoring methods in terms of gender and scbool type. The item scores collected from 780 maale and 698 female students chosen from 15 etementary schools of 7 private and 8 puplic schools were analyzed using DMH coefficient and MH test statistics and logistic regression models. The research findings showed that most of the items have ignorable DIP in terms of both gender and school type. Only in one item did DIF favor the students attending private schools in terms of school type and female students in terms of gender.
