Ortak maddeli denk olmayan gruplar desenine ilişkin test eşitleme çalışması

Abstract

This research aims at testing the statistical equivalence of different forms of a test which are administered at the same time. For our purposes, an equating design with shared items was used for non-equivalent groups. Nonequivalent groups design with common items is used for problems that might arise in relation to the reliability and implementation of tests in which different forms are applied. The data set of the research was obtained from responses given by students participating in the PISA 2009 application within Turkey's sample. The data collected from the 761 students of 15 age group who had answered the 3rd and 10th booklets of the science studies literacy test were analyzed through Tucker Linear equating, Levine linear equating, frequency prediction and BraunHolland linear equating methods. The weighted mean error squares averages indices that were obtained through equating procedures were 0.046 for the Tucker-linear equating, 0.072 for the Levine-linear equating, 0.049 for frequency prediction, and 0.034 for the Braun-Holland linear equating. It was observed based on the WMSE coefficient that the Braun-Holland linear equating method was the most Özet

An Investigation of Group Invariance in Test Equating According to Gender

“…Similar results are obtained when the past studies are examined. A study by Demir & Güler (2014) compared frequency prediction equipercentile equating, Tucker, Levine and Braun-Holland Linear Equating methods and determined that the most appropriate method was Tucker equating method and also reported that Levine observed score equated method had the highest error. Topczewski et al, (2013) stated in their study in which they used a different version of Tucker, Angoff-Levine, congeneric -Levine and a different version of congeneric Levine by addressing the differences between the skills of the groups that Tucker equating method was the most suitable one in case that group variance is similar.…”

“…Multiple studies that investigate the group invariance condition according to different subgroups s available (Dorans, 2004;Yang, 2004;von Davier & Han, 2004;Yin, Brennan & Kolen, 2004;von Davier & Wilson, 2008;Yang & Gao, 2008, Yi, Harris & Gao, 2008Dorans, Liu & Hammond, 2008). However, although there are plenty of studies related to equating in Turkey (Kelecioğlu,1994;Şahhüseyinoğlu, 2005;Bozdağ & Kan, 2010;Kan, 2011;Kilmen, 2010;Gök, 2012;Öztürk, 2010;Kahraman, 2012;Kelecioğlu & Öztürk Gübeş, 2013;Mutluer, 2013;Demir & Güler, 2014;Atalay Kabasakal, 2014;İnci, 2014;Uysal, 2014), there is no more research which investigated group invariance of equating results. 2017).…”
