The present study investigates the influence of multidimensionality on linking and equating in a unidimensional IRT. Two hypothetical multidimensional scenarios are explored under a nonequivalent group common-item equating design. The first scenario examines test forms designed to measure multiple constructs, while the second scenario examines a…

This quantitative correlational study investigated the potential impact of technostress on rural high school teacher burnout. The purpose of this study was to determine the possible correlations between the five techno-stressors that make up technostress and the burnout experienced by rural Arkansas high school teachers. The person-environment fit…

Despite the increasing demand for diagnostic information, observed subscores have been often reported to lack adequate psychometric qualities such as reliability, distinctiveness, and validity. Therefore, several statistical techniques based on CTT and IRT frameworks have been proposed to improve the quality of subscores. More recently, DCM has…

When we read, errors in oculomotor programming can cause the eyes to land and fixate on different words from what the mind intended. Previous work suggests that these "mislocated fixations" form 10-30% of first-pass fixations in reading eye movement data, which presents theoretical and analytic issues for eyetracking-while-reading…

The United States higher education institutions' mission is to support students' academic success and career development goals by preparing them to become globally competent citizens and workforce-ready graduates. With student workforce preparation at the core of their mission, there is concern that colleges and universities are not adequately…

Nationally, there is a mounting interest in better understanding students identified as having an emotional disturbance. Since 2005, clinical diagnosis and treatment of mental health issues in children has trended upward. Nationally, over that same timeframe, the number of students who qualify for special education due to an emotional disturbance…

This dissertation presents a series of case studies concerned with whether the signal in a given set of measurements that we take in the course of linguistic inquiry reflects grammatical competence or performance factors. We know that performance and competence do not always covary, yet it is not uncommon to assume that measurements that we take…

Undocumented children have a right to a public k-12 education in the United States, however there is no standard approach to higher education. About half of states allow undocumented immigrants to attend public colleges and universities at in-state rates of tuition (ISRT) and a subset of these also allow them access to state financial aid. This…

This dissertation analyzes the production and perception of lexical stress in trilinguals' first, second, and third languages (L1, L2, and L3) to evaluate how the cue-weighting transfer hypothesis applies to L3 acquisition. According to this hypothesis, acoustic cues to stress have different weights across languages, and results from both…

The purpose of the current study is to shed a light on institutional internationalization efforts and undergraduate students' global learning outcomes in four-year higher education institutions in the United States exploring the topic at the student, institutional, and academic-major levels. Specifically, three research questions lead the study:…

This dissertation seeks to answer three loosely-related questions regarding ergativity. First, what is the nature of the morphological phenomena known as ERG=GEN and ERG=POSS? After providing a thorough description with ample data from a wide range of sources, a typological survey of 40 ergative languages concludes that together, they are a fairly…

This study was conducted to analyze potential item parameter drift (IPD) impact on person ability estimates and classification accuracy when drift affects an examinee sub-group. Using a series of simulations, three factors were manipulated: (a) percentage of IPD items in the CAT exam, (b) percentage of examinees affected by IPD, and (c) item pool…

Multi-word sequences are important components of language because they are building blocks that can be used to create long stretches of discourse. They are word combinations that have particular importance because of their co-occurrence and function in discourse that suggest that they are stored and retrieved from memory as a whole rather than as…

Statement of Purpose and Method of Study: Historically, Mississippi has lagged behind the rest of the nation in student achievement and funding for education. This comparative quantitative study investigated whether significant differences in student achievement as measured by mean composite ACT scores of high school juniors in Mississippi public…

A key task in the professional development of counselors is the formation and refinement of their theoretical orientation, a framework based in theories of counseling and psychotherapy which helps one to understand human behavior and guide the therapeutic process. This study sought to explore counselor viewpoints on the current stage of their…
