Aberrant Responding With Underlying Dominance And Unfolding Response Processes: Examining Model Fit And Performance Of Person-Fit Statistics, Jennifer A. Reimers
Aberrant Responding With Underlying Dominance And Unfolding Response Processes: Examining Model Fit And Performance Of Person-Fit Statistics, Jennifer A. Reimers
Graduate Theses and Dissertations
Researchers have recognized that respondents may not answer items in a way that accurately reflects their attitude or trait level being measured. The resulting response data that deviates from what would be expected has been shown to have significant effects on the psychometric properties of a scale and analytical results. However, many studies that have investigated the detection of aberrant data and its effects have done so using dominance item response theory (IRT) models. It is unknown whether the impacts of aberrant data and the methodology used to identify aberrant responding when using dominance IRT models apply similarly when scales …
Posterior Predictive Model Checking Of The Hierarchical Rater Model, Nnamdi Chika Ezike
Posterior Predictive Model Checking Of The Hierarchical Rater Model, Nnamdi Chika Ezike
Graduate Theses and Dissertations
Fitting wrongly specified models to observed data may lead to invalid inferences about the model parameters of interest. The current study investigated the performance of the posterior predictive model checking (PPMC) approach in detecting model-data misfit of the hierarchical rater model (HRM). The HRM is a rater-mediated model that incorporates components of the polytomous item response theory (IRT) model, such as the partial credit model (PCM) and generalized partial credit model (GPCM), at the second level of the hierarchy, to model examinees’ responses to performance assessments. To date, the HRM has not been rigorously evaluated using PPMC techniques. Monte Carlo …

Collegiate recreation programs and centers typically provide traditional programming space in addition to a range of physical activity spaces and resources, as a valuable part of the student experience. The external pressures of identifying and communicating departmental value and impact on the campus community has resulted in collegiate recreation departments’ use of data to communicate the effectiveness and impact of their work. The purpose of the study was to identify the data collection and assessment management practices of collegiate recreation departments, particularly focusing on the organization of data and assessment strategies as well as data collection, storage, reporting, analyzing, and …
Development Of An Effect Size To Classify The Magnitude Of Dif In Dichotomous And Polytomous Items, James D. Weese
Development Of An Effect Size To Classify The Magnitude Of Dif In Dichotomous And Polytomous Items, James D. Weese
Graduate Theses and Dissertations
A standardized effect size for the SIBTEST/POLYSIBTEST procedure is proposed, allowing for Differential Item Functioning (DIF) to be classified with a single set of DIF heuristics regardless of whether data are dichotomous or polytomous. This proposed standardized effect size accounts for both variability in responses and whether participants are included in the SIBTEST/POLYSIBTEST calculations. First, a new set of unstandardized effect size heuristics are established for dichotomous data that are more aligned with Educational Testing Service (ETS) standards using two and three parameter logistic (2PL and 3PL) models. Second, a standardized effect size is proposed and compared to other DIF …
How College Campuses Are Using Social Media During Severe Weather Events, Emmale Davis
How College Campuses Are Using Social Media During Severe Weather Events, Emmale Davis
Graduate Theses and Dissertations
This study explores how college campuses are using social media during severe weather events. This topic surfaced after a tornado devastated Moore, Oklahoma in May 2013 and those displaced flocked to the University of Oklahoma campus after a post made on Twitter went viral prior to an official message being sent out by the university. In order to further explore this topic, a qualitative phenomenological case study was conducted at the following sites: University of Alabama, Missouri Southern State University, University of Oklahoma, and Florida State University. This study included observations of social media posts on Facebook and Twitter on …
Analytical Comparison Of Contrasting Approaches To Estimating Competing Risks Models, Brian Stephen Rickard
Analytical Comparison Of Contrasting Approaches To Estimating Competing Risks Models, Brian Stephen Rickard
Graduate Theses and Dissertations
Survival analysis is a commonly used tool in many fields but has seen little use in education research despite a common number of research questions for which it is well suited. Researchers often use logistic regression instead; however, this omits useful information. In research on retention and graduation for example, the timing of the event is an important piece of information omitted when using logistic regression. A simulation study was conducted to evaluate four methods of analyzing competing risks survival data, Cox proportional hazards regression, Weibull regression, Fine and Gray's Method, and Cox proportional hazards regression with frailty. College student …
Examining Employees' Perceptions Of Energy Conservation Behaviors In Office Settings, Michele Belmont Halsell
Examining Employees' Perceptions Of Energy Conservation Behaviors In Office Settings, Michele Belmont Halsell
Graduate Theses and Dissertations
The estimates for potential energy and greenhouse gas (GHG) savings in office buildings are significant. Reports show that energy wasting behavior in office buildings such as computers being left on at night and on weekends result in billions of dollars lost annually and GHG's being emitted needlessly. The estimated potential for energy savings ranges from 20 to 50 percent. Despite the potential for significant energy savings, a review of the literature revealed that there are relatively few studies of energy conservation interventions in office buildings. Most of the research on energy conservation has been done in households. There is agreement …
Overcoming Roadblocks In Introducing Virtual World Technology To High Schools, Casey Dylan Bailey
Overcoming Roadblocks In Introducing Virtual World Technology To High Schools, Casey Dylan Bailey
Graduate Theses and Dissertations
The EAST (Environmental And Spatial Technology) Initiative is a non-profit educational organization that provides students in over two hundred schools in eight states with access to advanced computing technologies for the purpose of enabling students to develop technical skills early and to produce solutions to local community problems. Although many high-end technologies are available through EAST, they are desktop solutions that individual students use and there are none that enable students within a school or between schools to collaborate.
This thesis is a saga that documents the identification and removal of many roadblocks to introducing a 3D multi-user virtual simulation …
