استخدام نموذج راش في تدريج اختبار اللغة العربية لقبول طلبة المرحلة الثانوية المقبلين على الالتحاق بجامعة الكويت
The study aims to calibrate an Arabic language admission test for high school students who are applying to enroll in colleges of humanities at Kuwait University. An Arabic language admission test (60 items) was developed and administered to a sample of 729 high school students. Data were collected, entered and analyzed using both traditional psychometric techniques and Rasch analyses. Rasch model assumption was investigated, therefore unfit persons (11 students) and items (14 items) were deleted. Fit items (46 items) were calibrated using fit persons (718 students), resulted in developing a test with sound psychometric properties of the test. In addition, analyses of resulted estimates of items’ and persons’ parameters revealed an objective measurement. Estimate of item difficulty appears to be independent of person ability, and estimate of person ability appears to be independent of item difficulty. (Published abstract)
