For this dissertation, four item purification procedures were implemented onto the generalized linear mixed model for differential item functioning (DIF) analysis, and the performance of these item purification procedures was...
This study examined the effectiveness of the odds-ratio method (Penfield, 2008) and the multinomial logistic regression method (Kato, Moen, & Thurlow, 2009) for measuring differential distractor functioning (DDF) effects in comparison to...
Many studies have been conducted to evaluate the performance of DIF detection methods, when two groups have different ability distributions. Such studies typically have demonstrated factors that are associated with inflation of Type I...
The purpose of this study was to examine the coaching experience in charitable cause-based endurance training programs, in which participants receive coaching to complete a marathon or similar endurance athletic event in return for...
The focus of this study is to consider random differential item functioning (DIF) for polytomous items from a multilevel (3 level) logistic regression perspective. Often, in educational studies, three levels with nested variables are...
Making use of the observable response time data now available due to computerized testing offers exciting opportunities for the theory and practice of educational measurement. This study extends item response theory by developing a model...
There is a growing need to use response time data to improve measurement quality with the increasing popularity of computerized testing. This work simultaneously models item response and response time to improve on current IRT models...
