This dissertation compares the performance of equivalence test (EQT) and null hypothesis test (NHT) procedures for identifying invariant and noninvariant factor loadings under a range of experimental manipulations. EQT is the statistically appropriate approach when the research goal is to find evidence of group similarity rather than group…

In conducting confirmatory factor analysis with ordered response items, the literature suggests that when the number of responses is five and item skewness (IS) is approximately normal, researchers can employ maximum likelihood with robust standard errors (MLR). However, MLR can yield biased factor loadings (FL) and FL standard errors (FLSE) when…

The purpose of this study was to examine whether there was a statistically significant (p < 0.05) difference in student-athletes' resilience by whether they attended religious or secular higher education institutions. The study utilized data from the 2018 Multi-Institutional Study of Leadership (MSL) survey, which was completed by 8,163…

Measurement invariance is crucial for making valid comparisons across different groups (Kline, 2016; Vandenberg, 2002). To address the challenges associated with invariance testing such as large sample size requirements, the complexity of the model, etc., applied researchers have incorporated parcels. Parcels have been shown to alleviate skewness,…

Nonverbal behavior is essential in human interaction (Gullberg, de Bot, & Volterra, 2008; McNeill, 1992, 2005). For second language speakers, nonverbal features can be helpful for successful and efficient communication (e.g., Dahl & Ludvigsen, 2014). However, due to the complexity of nonverbal features, language testing institutions have…

Focus on instructional leadership for school principals continues to be prominent in educational research and reform, as accountability for student achievement increases. The relationship between instructional leadership and special education needs more representation in research and literature. In this study, a review of relevant historical and…

This dissertation explored whether unnecessary linguistic complexity (LC) in mathematics and biology assessment items changes the direction and significance of differential item functioning (DIF) between subgroups emergent bilinguals (EBs) and English proficient students (EPs). Due to inconsistencies in measuring LC in items, Study One adapted a…

This study of over 100 kindergarten through 12th grade teachers in southern California focused on the exploration of teacher spirituality, specifically relationship with God and spiritual connection to others, through investigating its predictive role on teacher self-efficacy, specifically efficacy in student engagement, instructional strategies,…

Two leading theories regarding the neurocognitive basis of attentional disorders are the executive dysfunction theory and the state regulation theory. The executive dysfunction theory takes a top-down approach, explaining the symptoms of ADHD as a byproduct of general deficits in executive functioning--particularly disinhibition. The state…

This quasi-experimental mixed methods study investigated the interaction between social emotional competencies and mathematics performance for students in grades 9-12 in the 2020-2021 academic year. An intervention was designed to bolster specific social emotional competencies, and a corresponding survey was designed to measure them. Nine high…

The purpose of this study was to assess the impact of acquiescence on both positively and negatively worded questions, both when unidimensionality was assumed and when it was not. To accomplish this, undergraduate student responses to a previously validated survey of student engagement were used to compare several models of acquiescence, using a…

Despite the fact that international students face challenges at the United States (U.S.) universities and colleges, little research exits on these student's sense of belonging. This study investigates the factors of sense of belonging for international students and provides insights on factors like academic adjustment, homesickness, peer…

Problem and Purpose: Much research over several decades has established the importance of ongoing professional learning for teachers and has identified what effective professional learning should look like. Little research has been done, however, on the professional learning practices of teachers in faith-based schools, and few studies have…

Research on attachment in adult relationships has included minimal studies to encompass a Hispanic population. Mexican Americans have specific characteristics grounded in historical, demographic, and family contexts which are different from other groups. Therefore, cross-cultural validation of instruments to assess family relationships increases…

Proficient reading comprehension provides an academic advantage for 21st century learners. However, students at the upper elementary level face increasingly challenging texts that require use of metacomprehension skills. Yet, there is a lack of formal instruction that assists students in practicing these metacomprehension skills in classrooms.…
