الأداء التفاضلي لفقرات اختبار القدرات الرياضية (TOMA-3)‎ تبعا لمتغير الجنس وأثره على دقة تقدير القدرة للأفراد ودالة المعلومات للاختبار وفق نظرية الاستجابة للفقرة

Abstract EN

This study aimed investigate differential item function of the test of mathematical abilities (TOMA-3) according to gender and its effect on the accuracy of estimating the person's ability and information function according to (IRT), to achieve the study objective, the researcher used the (TOMA-3) prepared by brown (2012).

the sample number (560) male and female students, the results of the statistical program (Bilog-Mg3) verified that (100) test item fit the three parameters model, (17) of which presented item differential (IDF).

and that they have an impact on the accuracy of estimating abilities, the results also showed that there between statistically significant differences estimating the functions of test information before and after removing the items with differential performance, which indicates that the deletion of these items.

from the test has reduced the values of standard errors for in estimating capabilities achieving accuracy estimating functions of the information related to it, which can contribute to achieving accuracy and efficiency in assessing students' abilities.
