Abstract

This study aimed to verify the One-dimensional Aassumption under Item Response Theory, Using Exploratory Factor Analysis Versus Confirmatory Factor Analysis. Comparative study. To achieve this aim, the concept of One-dimensional assumption was defined, and its importance, and the consequences resulting from its violation, were illustrated. The required conditions for One-dimensional were identified, and the One-dimensional Indicators were explained, in addition to the definition of structural equation model and its importance, and the required conditions of confirmatory analysis. were identified too. The indicators are discussed, exploratory factor analysis versus confirmatory factor analysis which they concede fit indicators. Among the procedures of the study was to generate data and generating an items were also generating the examinee's ability, and generating data rate (1000) were examined, test length (30) item, and Ability distribution (normal) according to Item Response Theory Models (three-parameter) and analysis of data generated depending on the software AMOS 21 and SPSS. The results showed confirmting the results of exploratory factor analysis with Confirmatory Factor Analysis for detecting the effectiveness of matching fit indicators. In addition especially the statistical indicators: RMR, RMSEA, IFI, GFI, AGFI. achieve One-dimensional assumption. Which comes confirmation of the indicators of exploratory factor analysis.

الملخص

هدفت الدراسة الحالية للتحقق من افتراض أحادية البعد باستخدام التحليل العاملي الاستكشافي مقابل التحليل العاملي التوكيدي، دراسة مقارنة. ولتحقيق هذا الهدف تم تعريف افتراض أحادية البعد وبيان أهميته والآثار الناجمة عن انتهاكه. وتم التعريف أيضا بمؤشرات الكشف عن أحادية البعد، إضافة إلى التعريف بنموذج المعادلة البنائية وبيان أهميته، والشروط اللازمة لإجراء التحليل العاملي التوكيدي كأحد تطبيقاته، وتمت مناقشة مؤشرات التحليل العاملي الاستكشافي مقابل مؤشرات التحليل العاملي التوكيدي وهي مؤشرات جودة المطابقة. ومن ضمن إجراءات الدراسة تم توليد البيانات، ومجموعة الفقرات، وقدرات للأفراد، ولتحقيق ذلك تم توليد بيانات بواقع (1000) مفحوص، وقد كان طول الاختبار (30) فقرة، وشكل توزيعات القدرة (طبيعي)، وفق النموذج الثلاثي المعلمة، تم تحليل البيانات المولدة باستخدام برمجية ((AMOS 21 وبرمجية SPSS. أظهرت النتائج تأكيد نتائج التحليل العاملي الاستكشافي للتحليل العاملي التوكيدي في الكشف عن افتراض أحادية البعد، إضافة إلى تفوق المؤشرات الإحصائية: (RMR), (RMSEA), (IFI) ,(GFI)(AGFI), . والذي يوصى باستخدامها في الكشف عن افتراض أحادية البعد والتي تأتي تأكيدا على مؤشرات التحليل العاملي الاستكشافي.
