Adolescent Internet Use, Academic Performances, And Problem Behaviors: Findings From A National Sample Of Rural And Urban China, Yunqi Wang

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

Adolescent internet use in non-western countries and its association with behavioral problems are understudied. Informed by Bronfenbrenner’s socioecological framework and displacement hypothesis, the present study explored adolescent internet use in rural and urban China, and examined the mediation of academic performances between internet use and problem behaviors. Drawn from a nationally representative program, samples for this study included 3,379 adolescents aged between 9-17 years from 29 provinces. Results showed that rural adolescents had less access to mobile phones and internet, as well as a lower frequency of internet use than urban peers. Hybrid structural equation modeling results revealed that academic …

Integrating Narratives With Digital Humanities Tools To Inform Holocaust Education Pedagogies, Beth S. Dotan

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

Holocaust educators have a concern regarding how to learn and teach about the Holocaust after survivors and liberators are no longer alive to provide first-hand testimony. In response to this dilemma, I have developed a digital humanities web portal unique to Nebraska to preserve the survivors’ and liberators’ collective and individual memories. The Nebraska Holocaust Survivor & WWII Veteran Network and Educational Portal, the product for this dissertation, integrates local narratives with digital humanities frameworks to establish a dynamic, public platform and provide various educational opportunities. The site encourages engagement with online primary resources of Holocaust survivors and Nazi camp …

Why I Keep Doing Science Fair: Using Constructivist Grounded Theory To Study Out-Of-School-Time Science Learning Among Females And Underrepresented Minorities, Justin Andersson

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

Science education in the United States has endured substantial reform due to national needs for a bolstered, more diverse science, technology, engineering, and mathematics workforce. Recent reform efforts call for students to be engaged in scientific inquiry through the practices of scientists and engineers. Opportunity gaps exist in science education and in the STEM pipeline for those who have traditionally been underrepresented, especially females and minorities. Research highlights the potential of science fair experiences to engage students in inquiry learning that could meet the needs of updated standards. Furthermore, students from diverse backgrounds might benefit from out-of-school time science learning …

Phonics And Spelling Intervention For Children With Intellectual Disabilities, Bridget Leutzinger

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

The current study is a replication and adaptation of Lemons and colleagues (2018) by using an explicit, adapted version of the SPARK curriculum to assess its effectiveness on the literacy outcomes for students with Down Syndrome. The primary purpose was to determine the effectiveness of the explicit reading intervention package (independent variable) on letter-sound knowledge (dependent variable) in elementary students with DS. The secondary purpose was to evaluate whether the explicit spelling intervention of letter-sound correspondence generalized the spelling skills of whole taught and untaught words. Two students, ages 10 and 11, participated in a multiple probe across lessons single-case …

Experiences With Vitamin A In Copperbelt Province, Zambia, Topacio Ortiz

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

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., …

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 …
