Abstract

This study aimed to reveal the gender related differential item functioning for Jordanian national test items for mathematics learning quality control for tenth grade. The sample of the study consisted of 2400 students (1200 males and 1200 females) who took the exam for the year 2013/2014. To achieve the purpose of the study we used the students responses at the test which consist of (39) items by using Measures of Differential Functioning of Items and Tests (Noncompensatory: NCDIF), where the items in its final form was (25) items for one-parameter logistic model and (34) items for two-parameter logistic model. The results revealed that there is a uniform differential functioning for (9) items out of (16) common items and revealed non- uniform differential functioning for (15) items out of (26) common items. This study concluded a number of recommendations claiming different studies in other subjects related to differential item functioning in the national test of the learning quality control. And Detection of differential item functioning of other national tests that have been applied to students electronically.
