An Examination Of The Psychometric Properties Of The Student Risk Screening Scale For Internalizing And Externalizing Behaviors: An Item Response Theory Approach, Sara E. Moulton
Theses and Dissertations
This research study examined the psychometric properties of the Student Risk Screening Scale for Internalizing and Externalizing Behaviors (SRSS-IE) using Item Response Theory (IRT) methods among a sample of 2,122 middle school students. The SRSS-IE is a recently revised screening instrument aimed at identifying students who are potentially at risk for emotional and behavioral disorders (EBD). There are two studies included in this research. Study 1 utilized the Nominal Response and Generalized Partial Credit models of IRT to evaluate items from the SRSS-IE in terms of the degree to which the response options for each item functioned as intended by …
The Development And Validation Of A Spanish Elicited Imitation Test Of Oral Language Proficiency For The Missionary Training Center, Carrie A. Thompson
The Development And Validation Of A Spanish Elicited Imitation Test Of Oral Language Proficiency For The Missionary Training Center, Carrie A. Thompson
Theses and Dissertations
The Missionary Training Center (MTC), affiliated with the Church of Jesus Christ of Latter-day Saints, needs a reliable and cost effective way to measure the oral language proficiency of missionaries learning Spanish. The MTC needed to measure incoming missionaries' Spanish language proficiency for training and classroom assignment as well as to provide exit measures of institutional progress. Oral proficiency interviews and semi-direct assessments require highly trained raters, which is costly and time-consuming. The Elicited Imitation (EI) test is a computerized, automated test that measures oral language proficiency by having the participant hear and repeat utterances of varying syllable length in …
Investigating How Equating Guidelines For Screening And Selecting Common Items Apply When Creating Vertically Scaled Elementary Mathematics Tests, Maria Assunta Hardy
Investigating How Equating Guidelines For Screening And Selecting Common Items Apply When Creating Vertically Scaled Elementary Mathematics Tests, Maria Assunta Hardy
Theses and Dissertations
Guidelines to screen and select common items for vertical scaling have been adopted from equating. Differences between vertical scaling and equating suggest that these guidelines may not apply to vertical scaling in the same way that they apply to equating. For example, in equating the examinee groups are assumed to be randomly equivalent, but in vertical scaling the examinee groups are assumed to possess different levels of proficiency. Equating studies that examined the characteristics of the common-item set stress the importance of careful item selection, particularly when groups differ in ability level. Since in vertical scaling cross-level ability differences are …
The Strength Of Multidimensional Item Response Theory In Exploring Construct Space That Is Multidimensional And Correlated, Steven Gerry Spencer
The Strength Of Multidimensional Item Response Theory In Exploring Construct Space That Is Multidimensional And Correlated, Steven Gerry Spencer
Theses and Dissertations
This dissertation compares the parameter estimates obtained from two item response theory (IRT) models: the 1-PL IRT model and the MC1-PL IRT model. Several scenarios were explored in which both unidimensional and multidimensional item-level and personal-level data were used to generate the item responses. The Monte Carlo simulations mirrored the real-life application of the two correlated dimensions of Necessary Operations and Calculations in the basic mathematics domain. In all scenarios, the MC1-PL IRT model showed greater precision in the recovery of the true underlying item difficulty values and person theta values along each primary dimension as well as along a …
