Value Added By Using Joint Displays In Mixed Methods Research, Elizabeth Svoboda

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Mixed methods research collects, analyzes, and integrates rigorous qualitative and quantitative methods to gain a deeper understanding of a phenomenon than would be gained by using either method alone. Integration is one of the key features of mixed methods research and consists of mixing qualitative and quantitative research in a systematic way to generate new inferences or follow-up studies. However, the process of integration can be challenging to draw on expertise in both qualitative and quantitative methods, decide when and how to integrate qualitative and quantitative research, and combine multiple data sources in a coherent way to generate new inferences. …

Practical Recommendations For Mixed Methods Sampling In Psychological Intervention Research: A Mixed Methods Case Study, Analay Perez

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Sampling is integral to the research process and, if not appropriately addressed, can affect the meta-inferences of the mixed methods study. Sampling is also closely related to recruitment, retention, and additional methodological components. Sampling issues are magnified in social and health sciences intervention research due to the temporal placement of data collection and analysis. Limited research has examined sampling based on researchers’ rationales and decision-making across mixed methods psychological intervention research. This study explored this phenomenon to develop and refine a list of practical recommendations for sampling in mixed methods that were tested using content validity.

The Examination Of Nonparametric Person-Fit Statistics As Appropriate Measures Of Response Bias In Ordered Polytomous Items, Mark F. Beck

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Survey research is ubiquitous within the social sciences; however, surveys are vulnerable to response biases. Response biases introduce construct-irrelevant variance into survey responses, which degrades the accuracy of conclusions drawn through the use of surveys. Nonparametric person-fit statistics have been shown to accurately identify response biases in dichotomous response data but are not well studied in polytomous response data. This study examines the accuracy of nonparametric person-fit statistics in polytomous response data. A 6 x 4 x 4 x 2 simulation study was conducted, with type of aberrancy (6), number of response options (4), dimensionality (4), and test length (2) …

Job Stress Moderates The Effects Of A Mindfulness Intervention On Early Childhood Teachers' Emotion Dysregulation, Emily J. Starr

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Addressing the current crisis of early childhood (EC) teacher turnover is essential for supporting the development of young children. Teacher attrition remains a concern for policymakers globally, and in the United States, early childhood teachers frequently cite job stress and lack of support as reasons for leaving the field. For over 40 years, researchers who study childcare have been concerned about the consequences of work-related stressors. Even if these stressors do not result in turnover, EC teachers’ psychological well-being may be impacted, leading to increased emotion regulation difficulties and more frequent negative teacher-child interactions. Young children’s emotional development is significantly …

Following The "Iron Lady" And Finding A University: A Phenomenological Study Of Organizational Identity, Erin Pearson

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Higher education culture is steeped in institutional identity and ties to history. But what happens when that history is challenged, and an institution must change its name? While a merger was not initially intended for Kearney State College, merging into the University of Nebraska system was the only way to reflect the change and growth that emulated the type of institution it had become. By interviewing sixteen participants that lived the experience of the merge, a concise and collective history of the events that led to the creation of the University of Nebraska at Kearney was obtained and studied. Through …

Vitamin A deficiency (VAD) is one of the most common micronutrient deficiencies in Sub-Saharan Africa. Zambians face high VAD rates, despite a mandate for fortified sugar and crops. Limited data have been collected from the most vulnerable segments of Zambia’s population; hence this study was designed as an initiatory study for future research to be conducted with primary school children and pregnant women in Zambian communities.

Once IRB approvals were obtained from the University of Nebraska-Lincoln (UNL) and the Copperbelt University School of Medicine, data were collected in Zambia’s Copperbelt Province, in the cities of Ndola and Luanshya, during May …

A Latent Class Analysis Of Personality Traits With Educational Attainment, Tyler Minter

College of Education and Human Sciences: Dissertations, Theses, and Student Research

The five-factor model of personality (extraversion, agreeableness, conscientiousness, neuroticism, openness to experience) is an empirically based personality model that has been utilized in multiple psychological assessments. Recent works have found Block & Block’s (1980) three personality profiles (resilient, overcontrolled, undercontrolled) within the context of the five-factor model. This study performed a latent class analysis using a short FFM assessment from the SAPA project, a free online personality test. The intention of this study was to replicate the three personality profiles within the five-factor model. Four latent classes were included in the final solution. Two of the three personality profiles emerged …

Non-Nutritive Suck Burst Pattern Stability In Extremely Premature Infants, Alejandra Marquez

College of Education and Human Sciences: Dissertations, Theses, and Student Research

The development of non-nutritive suck (NNS) burst dynamics in preterm infants reflects the integrity of the brain and is used clinically to assess feeding readiness and orofacial motor development (Mizuno and Ueda, 2005). The application of NNS analytics in the present report represents one outcome measurement set that is part of an ongoing clinical trial involving extremely preterm infants (EPI’s,[GA]) randomized to receive either pulsed orocutaneous stimulation therapeutics or a sham (blind pacifier), in conjunction with salivary sampling twice weekly to map gene expression of key proteins involved in neural development and molecular sensing of feeding related pathways in the …

Analyzing Clustered Longitudinal Data Using Latent Curve Model With Structured Residuals (Lcm-Sr), Dongho Choi

College of Education and Human Sciences: Dissertations, Theses, and Student Research

The LCM-SR can provide an inferential basis for understanding reciprocal relations while controlling for individual differences in the trajectories of young children’s psychological development. Yet, a hierarchical structure in the data has not been often adequately addressed even though that is common in social and educational research. The purpose of this study is to explore the impact of dependency among observations on the results when using the LCM-SR, and how to appropriately analyze the clustered longitudinal data for more accurate inference. To do this, the MLCM-SR (disaggregated approach; the “two-level” model) was introduced and compared with the single level LCM-SR …

Education Anywhere? A Constructivist Grounded Theory Study Of Montessori Around The World, Victoria J. Johnson

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Providing education for children residing in remote or difficult-to-access locations, including children in refugee and displacement camps, is a staggering global challenge. In addition to logistical challenges (such as access, infrastructure, teaching professionals and resources), differences in language, culture, environment, and values render conventional (i.e., Western-based, traditional) modes of education unfeasible and frequently ineffective. However, a strengths-based lens reminds us that communities have the capacity to initiate solutions when they have access to the right tools. Historically underrepresented in the literature, Montessori education has been used for over a century by communities all over the world to prepare children through …

Understanding Unwanted Sexual Experiences Of Transgender And Gender Diverse Individuals: An Interpretative Phenomenological Study, Melissa Larosa

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Transgender and gender diverse (TGD) people represent a small percent of the population and yet, they experience sexual violence at disproportionately high rates compared to their cisgender counterparts (Grant et al, 2011; James et al., 2016). The purpose of this interpretative phenomenological study is to gain a more nuanced understanding of the role that unwanted sexual experiences play in the lives of transgender and gender diverse people, particularly in relation to how they conceptualize their gender identity and the construct of posttraumatic growth (PTG). Semi-structured interviews were conducted with eight TGD participants who met the inclusion criteria. Two superordinate (i.e., …

Assessing The Role Of Biology Undergraduates' Metacognitive Calibration And Neural Activity During Model-Based Reasoning, Mei Grace Behrendt

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Metacognition refers to the critical awareness of or ability to monitor, regulate, control, and sequence of one's thoughts and performance. There is limited research that examines the relationship between metacognition and (a) academic performance and (b) general cognition among undergraduates. Moreover, there is an even greater paucity of literature that focuses more specifically on undergraduate biology students’ neural activity in relation to their metacognition.

This study aimed to examine the relationship between undergraduate life sciences students' metacognitive calibration, i.e., their capacity to self-evaluate their own performance, and their behavioral performance and brain activity during a biological error reasoning task. Thirty-four …

Correlation Of The Anterior Salience Network With Attention: A Resting-State Fmri Analysis, Matthew Brooks

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Background: Some studies have broadened our understanding of attention while other studies have used resting-state functional magnetic resonance imaging (fMRI) analyses to identify brain regions that are functionally connected and may be associated with salience processing. This thesis sought to examine the relationship between the anterior salience network and attentional control. The current study hypothesized that resting-state functional connectivity between regions of the anterior salience network would be associated with attentional control ability. Methods: Forty-eight college-aged students completed the affective Stroop task to assess attentional regulation ability. Accuracy on trials of the task was examined in correlation with resting-state functional …

Embracing A Pedagogy Of Care In The Infant And Toddler Classroom, Paige D. Wernick

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Care is a universal concept which connects us all as humans. Everyone comes into this world needing care and most of us will exit this world in need of care. Care is necessary throughout the span of our lives and should be considered a human right. Everyone is entitled to quality care, no matter their age or social status. The U.S. society has been entrenched in a decades long division between education and care which has historically prioritized education over care. This division has contributed to care being hidden and undervalued within the context of early childhood (EC) as a …

Relational Trust In Group Coaching With First-Grade Teachers: A Single Case Study, Jentry Stoneman Barrett

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Coaching has become a prominent professional development tool for helping early childhood teachers implement curriculum and research-based practices in their classrooms. One of the coaching strategies found to create positive changes in teacher practice and child outcomes is building trust between the coach and teacher(s). Despite what is known in terms of the benefits of these positive relationships, there is limited understanding of the nature of trust-building between coach and teachers, in general, and particularly in group coaching configurations. There is also scant literature exploring the nature of trust between teachers participating in group coaching sessions. Researchers call these two …

An Intersectionality Framework On The Role Of Student-Teacher Relationships On Student Social Outcomes, Kenji Madison

College of Education and Human Sciences: Dissertations, Theses, and Student Research

This research aimed to build on the great wealth of knowledge on student-teacher relationships, social competence, and peer outcomes while utilizing a different approach integrating race and gender. The view of intersectionality may influence those who join in reading this research to consider race coupled with student gender as a strong influence affecting the formation of a relationship as instrumental as the student-teacher relationship.

In a sample of 10,886 (8489 White, 2397 Black) students from third to fifth grade, the research completed three aims: characterizing the relationship between teacher rated closeness and conflict and students’ social outcomes in fourth and …

Neurobehavioral Correlates Associated With Melodic Intonation Therapy For Adults With Nonfluent Aphasia, Caitlin Norquist

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Recent trends in neuroimaging, as it relates to the field of communication disorders, have shed new light on the nature of neuroplasticity and reorganization of brain function as it pertains to recovery from nonfluent aphasia following Melodic Intonation Therapy (MIT). However, demographic limitations in these client populations necessitate synthesis across individual studies to form meaningful patterns for application to clinical practice. We conducted a systematic review of all studies involving pre-and post-treatment neurological and behavioral measures following MIT treatment for adults with nonfluent aphasia. Ten studies were identified for synthesis involving a variety of languages, treatment conditions, and neuroimaging and …

Teaching Writing Strategies To Students Who Are Deaf Or Hard Of Hearing, Kyrie Kellogg

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Students who are deaf or hard of hearing (DHH) may access language differently than their typical hearing peers, or they may require additional supports and accommodations. This can lead to differences in communication modes and styles that can make communication and language development difficult, which can impact reading and writing skills. When their specific writing concerns are addressed, writing offers these students another outlet to express their ideas, share thoughts, and engage in meaningful communication with others. The purpose of this study was to examine whether Self-Regulated Strategy Development (SRSD) persuasive writing strategies would help improve writing length and quality …

Starting School Socially And Behaviorally Ready: The Impacts Of Malleable Home- And School-Based Relationships And Community Setting, Rachel Schumacher

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Children growing up in disadvantage often enter school without the requisite social, emotional, and behavioral skills to be successful. Considering the importance of social-emotional skills for school and later life success, it is critical to understand factors associated with social-emotional development across the transition to elementary school. The current study will utilize an ecological approach to identify the influence of malleable home- (i.e., parent-child relationship [microsystem]) and school-based (i.e., home-school connection [mesosystem]) contextual factors over time (chronosystem) on children’s school readiness and social-emotional adjustment to early elementary school, and uncover the role of community setting (exosystem) in understanding children’s school …

Investigating The Fit Of The Generalized Graded Unfolding Model (Ggum) When Calibrated To Irt Generated Data From Dominance And Ideal Point Models, Abdulla Alzarouni

College of Education and Human Sciences: Dissertations, Theses, and Student Research

The assessment of model fit in latent trait modelling, better known as item response theory (IRT), is an integral part of model testing if one is to make valid inferences about the estimated parameters and their properties based on the selected IRT model. Though important, the assessment of model fit has been less utilized in IRT research than it should. For example, there have been less research investigating fit for polytomous dominance models such the Graded Response Model (GRM), and to a lesser extent ideal point models such as the Generalized Graded Unfolding Models (GGUM), both in its dichotomous and …

Understanding The Needs And Knowledge Base Of Developing Speech-Language Pathology Programs: A Preliminary Mixed Methods Survey In The United States, Elaine Williams

College of Education and Human Sciences: Dissertations, Theses, and Student Research

The field of speech-language pathology provides important rehabilitation services for communication and swallowing disorders. Unfortunately, these services are lacking around the world, specifically in Majority countries, formally known as third world countries. This is significant given the high proportion of people with disabilities in Majority countries. While speech-language pathology services are actively being introduced to these areas, it is often with the inappropriate transfer of Minority world values. In an effort to provide a less biased and more formal approach to collaborating with countries requesting help to establish speech-language pathology services, the author of this thesis is proposing a process …
