Bireyselleştirilmiş Bilgisayarlı Test Uygulamalarında Madde Kullanım Sıklığı Kontrol Yöntemlerinin İncelenmesi

Abstract

It has been seen that some issues that could imperil the validity of the tests are arisen after the Computerized Adaptive Testing (CAT) administrations have been preferred recently. These issues such as skewness of the item pool utilization, the possibility of remembering the over-exposed items by examinees, not being able to progress the sustainability of item pool are caused to add new a component to CAT. Therefore item exposure control methods have been developed in order to ensure test security and to make the use of item pool more efficient. This study aims at investigating the various item exposure control methods in CAT under dichotomously IRT model by using different item pool characteristics and item selection methods in terms of measurement presicion and test security.
