A Collaborative & Strategic Approach To Improve School Achievement Through Effective Attendance/Truancy Policies And Procedures, Hector Freytas

Dissertations

The purpose of this program evaluation was to review the current attendance/truancy policies and procedures of Mountain West High School (MWHS), identify gaps and concerns, analyze data, and make actionable recommendations that would foster improvement in academic achievement through attendance efforts. A growing body of research indicates that missing 10% or more of the school places students at risk of failing general education courses, having low grade point averages (GPA), and performing poorly on standardized testing in relation to peers with “good” attendance (i.e., 95% average daily attendance [ADA] or better). In addition, students who miss this much school time …

Becoming A Learning System That Maximizes The Modes Of Professional Learning: A Change Leadership Plan In A Middle School Setting, Emily Crement

Dissertations

This paper follows a program evaluation conducted at Hamlin Middle School. It begins with the premise that the Modes of Professional Learning function somewhat independently of each other and therefore, Hamlin Middle School fails to function of a learning system. The goal of the research is to establish a set of structures that leverages each of the four modes to their greatest advantage. The methodology is mixed method, utilizing quantitative results from the Illinois 5Essential Survey and qualitative data gathered during focus groups that convened to discuss the survey data. Results suggested that a) a culture of compliance negatively impacts …

Data included a survey of 61 kindergarten, first, and second-grade teachers and two focus group interviews in a large urban district in the Midwest. Three major themes emerged from the data concerning the writing instructional practices: (a) the importance of peer collaboration on instructional practices and professional learning, (b) the consistent use of a common writing curriculum, and (c) the application of a Writer’s Workshop approach. The findings suggest that because writing is not a consistent …

A Novel Linear Diophantine Equation-Baesd Low Diameter Structured Peer-To-Peer Network, Shahriar Rahimi

Dissertations

This research focuses on introducing a novel concept to design a scalable, hierarchical interest-based overlay Peer-to-Peer (P2P) system. We have used Linear Diophantine Equation (LDE) as the mathematical base to realize the architecture. Note that all existing structured approaches use Distributed Hash Tables (DHT) and Secure Hash Algorithm (SHA) to realize their architectures. Use of LDE in designing P2P architecture is a completely new idea; it does not exist in the literature to the best of our knowledge. We have shown how the proposed LDE-based architecture outperforms some of the most well established existing architecture. We have proposed multiple effective …

Interactions Between Amyloid-Beta And Microglial Cells, Lisa Gouwens

Dissertations

Alzheimer’s disease (AD), the most common cause of dementia, is a neurodegenerative condition characterized by loss of memory and intellectual abilities. Intracellular plaques of aggregated amyloid-beta (Ab) protein are a well-known pathology associated with AD. Although symptoms usually appear late in life, the accumulation of Ab begins decades earlier and causes activation of microglia, the brain’s immune cells. The ensuing inflammation contributes significantly to neurodegeneration. Determination of the particular form of Ab that causes the most damage in the brain is one of the major questions in the AD field. My research focused on the interactions of microglia with monomers, …

Processing Motion: Using Code To Teach Newtonian Physics, M. Ryan Massey

Dissertations

Prior to instruction, students often possess a common-sense view of motion, which is inconsistent with Newtonian physics. Effective physics lessons therefore involve conceptual change. To provide a theoretical explanation for concepts and how they change, the triangulation model brings together key attributes of prototypes, exemplars, theories, Bayesian learning, ontological categories, and the causal model theory. The triangulation model provides a theoretical rationale for why coding is a viable method for physics instruction. As an experiment, thirty-two adolescent students participated in summer coding academies to learn how to design Newtonian simulations. Conceptual and attitudinal data was collected using the Force Concept …

School Connectedness As A Moderator Between Racial Microaggressions And Academic Performance For African American High School Students, Courtney Wilson

Dissertations

Racial microaggressions are subtle, often unconscious, words or actions that demean African Americans (Sue et al., 2007). The impact of racial microaggressions may not be seen, and so it is important to study potential long-term consequences such as academic performance. This study addressed an identified gap in the literature on the relationship between racial microaggressions and academic performance among African American high school students. A quantitative design was used to study the relationship between racial microaggressions and academic performance, and school connectedness as a moderating variable of this relationship. There were 417 high school students who completed the surveys. Of …

Everyone, has at least once, encountered the difficulties involved with deciding what to do as a group. Some friends may be busy, others may have already seen the movie that the others want to see, and some do not like Mexican food. It is a challenge everyone has faced and continue to face. This is a result of …

Biophysical Mechanisms Of Frequency-Dependence And Its Neuromodulation In Neurons In Oscillatory Networks, David Michael Fox

Dissertations

In response to oscillatory input, many isolated neurons exhibit a preferred frequency response in their voltage amplitude and phase shift. Membrane potential resonance (MPR), a maximum amplitude in a neuron’s input impedance at a non-zero frequency, captures the essential subthreshold properties of a neuron, which may provide a coordinating mechanism for organizing the activity of oscillatory neuronal networks around a given frequency. In the pyloric central pattern generator network of the crab Cancer borealis, for example, the pacemaker group pyloric dilator neurons show MPR at a frequency that is correlated with the network frequency. This dissertation uses the crab …

Erosion Behavior And Scour Risk Of Extremely Coarse Streambeds, Abolfazl Bayat

Dissertations

Bridge scour, which is the erosion of soil and rock around bridge abutments and piers, is the principal cause of bridge failure in the United States and around the world. Previous investigations of scour have focused mostly on fine sediments such as sand, silt, and small gravel, because such alluvium underlies a majority of bridges. The erosion resistance of coarser sediments has received limited attention to date, even though they dominate many small to medium-size rivers in the northern tiers of the United States, Europe, and Asia. This study focuses on the scour behavior of extremely coarse particles (ECP), namely …

Engagement’S Mediation Of The Relationship Between Personalized Learning And Achievement, John-Patrick Grant Clark

Dissertations

The present study investigates the effect of engagement as a mediating variable on the relationship between personalized learning and achievement. Personalized learning involves instruction and learning that is individualized to the student by means of several components. These components include goal-oriented mastery learning, flexible pacing, ongoing formative assessment feedback, and the incorporation of personalized information. The literature suggests that each of these components, both individually and as a whole, have a positive correlation with achievement. Engagement may mediate this relationship given that it involves the students’ willingness to involve themselves in the learning process through the use of certain behavioral, …

Like many southern states, South Carolina has a history permeated by issues related to race, equity, and educational opportunity. As early as the 1949 South Carolina court case, Briggs v. Elliott, South Carolina has had to address issues of equity and educational opportunity among its disenfranchised and marginalized citizenry. More than 60 years later, in Abbeville County School District et al. v. the State of South Carolina et al., sectors of rural South Carolina, predominantly black and poverty laden, would unite and engage in a legal battle with the State over equity in public education and by judicial mandate, be …

Technology Integration And English Language Learners, Joshua James Carter

Dissertations

The purpose of this study was to examine teachers’ levels of mobile device implementation and any measured differences in English Language Learners’ (ELLs’) performance in each modality of the ACCESS test. Researchers often support the use of mobile devices in the classroom, but this study was unique because of a combination of how it was focused solely on language development in ELLs, how classrooms were placed on the SAMR spectrum, and how student performance was analyzed in each modality measured by the ACCESS test (Budiman, 2014; Donahue, 2014; Marek, 2014; Mulcahy, 2017). Included in this study were 37 classrooms and …

Perceptions Of School Leaders Regarding The Benefits Of Leadership Dashboards, Chance A. Wistrom

Dissertations

Implementation of continuous improvement structures in education continues to expand as demands for accountability increase in response to ongoing educational reform (Frickx, 2015). Park, Hironaka, Carver, and Nordstrum (2013) found the systemic nature of educational organizations often inhibits these organizations from successfully implementing continuous improvement structures characteristic of high-reliability organizations. Specifically, system leaders in educational entities are ill-equipped to lead system improvement due to poor preparation and lack of focus on specific implementation drivers (Kirkpatrick & Kirkpatrick, 2014). This has resulted in a need for educational system leaders to develop a leadership dashboard similar to dashboards created by Jack Stack …

Topics On Multiple Hypotheses Testing And Generalized Linear Model, Yalin Zhu

Dissertations

In applications such as studying drug adverse events (AE) in clinical trials and identifying differentially expressed genes in microarray experiments, the data of the experiments usually consists of frequency counts. In the analysis of such data, researchers often face multiple hypotheses testing based on discrete test statistics. Incorporating this discrete property of the data, several stepwise procedures, which allow to use the CDF of p-values to determine the testing threshold, are proposed for controlling familiwise error rate (FWER). It is shown that the proposed procedures strongly control the FWER and are more powerful than the existing ones for discrete data. …

Response To Intervention: A Study Of Intervention Programs In Rural Secondary Schools, Richard William Wylie Jr.

Dissertations

During the late 20th and early 21st centuries, a trend developed for schools to meet the needs of struggling and at-risk learners through the implementation of multi-tiered response to intervention models (Apple, 2014). Response to intervention (RtI) is one of those frameworks and has been extensively researched from the perspective of those working in urban elementary schools (Burns & Gibbons, 2013). This research project was designed to allow for better understanding of the rural secondary perspective of RtI through investigation of the perceptions of administrators, counselors, and educators who have implemented RtI frameworks. This qualitative examination resulted in a narrative …

A Comparative Analysis Of Missouri Elementary School Arts Curriculums, Shenicquel Larene Spotts

Dissertations

Since the beginning of recorded history, artists of distinction have contributed to society’s aesthetic sensibilities through their media of choice. The lives of these artists continue through their visually recorded work. We see their best products featured in history books and films, thus generally contributing to our day-to-day lives. Despite the influence of art on society, this deep and multi-faceted subject is often among the first to be cut during periods of economic instability or budget constraints. While funding may reflect the impact of arts programs on the educational experience, the true value of arts programs emerges when their usefulness …

Testing The Double-Deficit Hypothesis In Arabic Language Among Emirati Students In Grade-3, Mahmoud Fahid Mohammad Gharaibeh

Dissertations

The purpose of this dissertation was to test the validity of the double-deficit hypothesis as applied to a sample of third-grade Arabic-speaking students in the United Arab Emirates. The double-deficit hypothesis postulates that individuals with a combination of Rapid Automatized Naming (RAN) and Phonological Awareness (PA) deficits will tend to have worse reading ability than individuals with either a RAN deficit, a PA deficit, or no deficit. Thus, the double-deficit hypothesis has been advanced as an explanation of dyslexia. Descriptive statistics were used to describe the essential feature of data in the study, and a correlational study design was applied …
