Clustering Educational Digital Library Usage Data: Comparisons Of Latent Class Analysis And K-Means Algorithms, Beijie Xu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There are common pitfalls and neglected areas when using clustering approaches to solve educational problems. A clustering algorithm is often used without the choice being justified. Few comparisons between a selected algorithm and a competing algorithm are presented, and results are presented without validation. Lastly, few studies fully utilize data provided in an educational environment to evaluate their findings. In response to these problems, this thesis describes a rigorous study comparing two clustering algorithms in the context of an educational digital library service, called the Instructional Architect.

First, a detailed description of the chosen clustering algorithm, namely, latent class analysis …

Exploring The Relationship Between Place Identity And Personalization Of Space In Temporary Student Housing, Joshua H. Rowley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study is to better understand the relationship between the personalization of one’s physical environment and the degree of place identity the person has toward their space, specifically those living in temporary student housing. There have been several studies on peoples’ inherent need to personalize their space. While previous research has identified key factors that help to define place identity in general, this study addresses the fact that not much has been said about how people in temporary housing, specifically student housing, actually go about creating their living spaces.

The key issues this research addressed were the …

Sexual And Religious Identity Development Among Adolescent And Emerging Adult Sexual Minorities, Angie L. Dahl

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As the majority of Americans identify with a religious affiliation, the religious context is an important backdrop upon which identity development occurs. For lesbian, gay, bisexual, transgender, queer, questioning, and allied (LGBTQA) youths, the process of development may be complicated in a religious context due to denominational positions on same-sex sexuality. While recent researchers highlighted the importance of contextual influences on LGBTQA developmental processes, few studies have examined LGBTQA sexual and religious identity development. The goal of the current study was to gain a better understanding and appreciation of LGBTQA adolescent and young adult experiences of religious and sexual identity …

Evaluating Reliability And Validity Evidence For Merrill's 2007 5 Star Instrument, Max Hale Cropper

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Merrill’s 2007 5 Star instrument, hereafter called the M-5 Star, is based on Merrill’s well recognized First Principles of Instruction. However, the instrument has not been tested for reliability and validity. In a pilot study, Cropper’s version of his instrument (C-5 Star) showed some reliability and validity evidence, but the M-5 Star needed similar evidence. To address this gap in the literature, the purpose of this study is to assess the reliability and validity evidence for M-5 Star. Raters were drawn from a graduate course in online course evaluation and asked to rate a sample (N = 6) of …

Fluency Instruction In Contemporary Core Reading Programs, Brady E. Donaldson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Core reading programs (CRPs) provide the curriculum and guide reading instruction for many classroom teachers. The purpose of this study was to conduct a content analysis of reading fluency instruction in current (2008-2011 copyright) grade 2 and 3 top-selling core reading program lessons to answer the following two research questions: (1) How do core reading programs recommend that fluency skills be taught? (2) How do reading fluency instructional practices in core programs compare to evidence-based reading fluency instructional practices defined in current research? The results of the analysis revealed that fluency instruction is more prevalent in current core reading programs …

Making The “Good” Professor: Does Graduate Mentoring Promote Gender Equality In Academia?, Anita Harker Armstrong

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Mentorship is a critical component of a graduate education and facilitates the process of socialization into the role of professorship. Numerous studies continue to support the idea that mentorship, particularly woman-to-woman mentoring, is essential for overcoming barriers to women’s mobility within male-dominated fields. This study critically examines this assumption through the analysis of 59 qualitative interviews with faculty mentors and graduate students in science, technology, engineering, and mathematics conducted at one Canadian and one American institution. Initially, I explore how mothers in academe are socialized from differing levels to fit into narrowly defined roles as “good” professors. This expands our …

A Social Norms Approach To College Alcohol Use: Drinking In A Low-Use Environment, Jared M. Cox

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Social norms interventions have been shown to be effective in reducing problematic alcohol use on college campuses. However, not all interventions have been successful, and the campus environment may be responsible for the variable reactions that students have to these interventions. The following three articles investigate the nature and utility of social norms interventions in an environment where alcohol use is relatively low. The first article details an online social norms intervention implemented on a low-use campus. Results suggest that if adapted to the campus culture, a social norms approach to reducing alcohol use could be successful in this unique …

Correspondence Of Job-Preference And Job-Matching Assessment With Job Performance And Satisfaction Among Youth With Developmental Disabilities, Julie Hall

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study investigated the effects of job preference and job match on job performance among four 19-to 20-year-old young adults with developmental disabilities placed in community-based job conditions. Prior studies have examined the effects of job preference on community-based job performance without the job-matching component. The researcher identified high-preference, high-match and low-preference, low-match job conditions and tasks using a video web-based assessment program. Each participant was subsequently placed in a randomized sequence of 30-min sessions on one high-preference, high-match job condition performing a preferred task and one low-preference, low-match job performing a non preferred task. Job coaches instructed and prompted …

Integrating Digital Technologies In The German Language Classroom: A Critical Study Of The Technology-Integration Experiences Of Three Secondary German Teachers, Stephen Van Orden

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

German language teachers are gaining increased access to smart classrooms and digital technologies that offer teachers and students greater access to authentic cultural and language materials and enable more student target language communication. Teaching with technology changes the teaching and learning environment in many ways. Little is known about how integrating technology into the daily German-language-teaching curriculum changes the implicit power structures embedded in all classroom interactions. Because of the central, decision-making role of the teacher, this study uses a critical theory of technology lens to examine the daily technology integration experiences of three secondary German language teachers. This study …

Young's Schema Theory: Exploring The Direct And Indirect Links Between Negative Childhood Experiences And Temperament To Negative Affectivity In Adulthood, Mark S. Jesinoski

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Young's schema theory offers a theoretical approach that relates negative childhood experiences, temperament, and early maladaptive schema, to the experience of negative affect and/or depression in adulthood. However, despite the widespread use of schema therapy in clinical practice, little research has explored the pathways theorized by Young. This study explored the pathways posited by Young and colleagues looking at the direct and indirect relationships among negative childhood experience, temperament, early maladaptive schema, and the experience of negative affect in adulthood. Self-report data were collected from 365 undergraduate students. Results demonstrated consistent and robust direct relationships between temperament and negative affect, …

The Rhetoric Of Space In The Design Of Academic Writing Locations, Amanda Nicole Metz Bemer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This dissertation explores the rhetoric of space as it relates to academic computer writing locations--specifically, computer labs, computer classrooms, and writing centers. Using observation, surveys, interviews, and textual analysis, the author discusses seven rhetorical principles of design for these spaces, including designing for specific audiences, attention, clarity, enthymematic flexibility, identification, pathos, and shared ethos. Ultimately, applying a rhetorical gaze to these areas can help us to design more effective computer spaces in academia.

Bosom Buddies: Factors Associated With Experiences Of Passionate Friendship Among Men And Women, Katherine A. Peterson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Scholars historically have separated friendships and romantic relationships into two qualitatively distinct relationship categories. Contemporary research examining passionate friendships, however, has identified qualities within platonic relationships that appear to mimic characteristics typically associated with romantic relationships. Primary critiques of the existing passionate friendship literature include exclusively examining females, including samples that predominately identified as lesbian, bisexual or questioning, and research utilizing solely qualitative designs.

The current study used a quantitative design to investigate 375 emerging adults' (18-26 years of age; 149 males, 226 females) friendship experiences. Specifically, four quasi-independent variables (i.e., biological sex, sexual orientation, gender-role orientation, and cross vs. …

The Essential Structure Of Compulsive Buying: A Phenomenological Inquiry, Letty Workman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

While many jokes and sales of specialty merchandise have been made that make light of consumers who frequently shop and buy (e.g., "When the going gets tough, the tough go shopping," or "I am a shopaholic"), for 18 million Americans suffering from compulsive buying, the process of shopping and buying has caused their lives to literally go out of control. The outcomes of this disease for individuals, families, and business are all negative. In a marketing era of social responsibility, if marketers either knowingly or unknowingly encourage increased consumption among compulsive buyers, potential negative outcomes stand to impact others well …

Attitudes Toward Immediate Annuities, Devon K. Robb

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Retirement security for Americans is one of the most critical public policy and personal financial issues and will be for decades in the future. Individuals that retire today can live an additional 30 or even 40 years with less secure income as corporations shift to defined contribution plans to fund retirement. Based on the life cycle savings hypothesis, immediate annuities should be appealing to retirees because they insure against the risks of outliving retirement assets by converting funds into a lifelong stream of income. However, research has found that retirees are reluctant to annuitize their wealth. This study examined the …

Thirty-seven couples who identified their marriages as being strong, happy, or highly satisfying, volunteered to be interviewed for this study. All individual participants (74 total) talked about finances in their marriages, and all interviews were used for the purpose of this study. Their descriptions were coded and analyzed to explore the way that they talked about money issues in their marriages. The research questions focused on …

Psychometric Properties Of Postsecondary Students' Course Evaluations, Michael J. Drysdale

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Several experts in the area of postsecondary student evaluations of courses have concluded that they are stable or reliable measures as well as being measures that provide ways of making valid inferences regarding teacher effectiveness. Often these experts have offered these conclusions without supporting evidence. Surprisingly, a thorough review of the literature revealed very few reported test-retest reliability studies of course evaluations and the results from these studies are contradictory. In the area of validity, the conclusions offered by scholars who conducted meta-analyses of mutlisection course studies are inconsistent. This leads to the following two research questions:

1. What is …

Environmental And Developmental Indicators In Early Childhood: Relations To Second-Grade Reading Comprehension, Gina A. Cook

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Reading success has been linked to high school completion, future job success, and future generations of children who can read. Unfortunately, children who are unable to read on grade level by the end of first grade are at a great disadvantage and unlikely to catch up later. Without the ability to read and comprehend text, all aspects of schooling become progressively more difficult and the challenge of poor reading ability can be so difficult to overcome that many poor readers will not complete high school. For these reasons, it is important to identify early experiences in a child's family environment …

Ordinary Spirits In An Extraordinary Town: Finding Identity In Personal Images And Resurrected Memories In Lily Dale, New York, Mary Catherine Gaydos Gabriel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Every summer, Lily Dale, New York, a community founded on spiritualist beliefs and steeped in an eccentric explosive past, hosts thousands of visitors seeking to communicate with dead friends and relatives, while the residents lead ordinary lives in the midst of the supernatural hype permeating their town. Their stories are considered by most to be secondary to the illustrious trappings of the community in which they occurred. My research employs oral histories prompted by personal photographs to showcase the residents' everyday experiences amidst the town's infamy, illuminating the undervalued individual experience of those living in communities of such extraordinary repute. …

Statistical Analysis Of The Usu Lidar Data Set With Reference To Mesospheric Solar Response And Cooling Rate Calculation, With Analysis Of Statistical Issues Affecting The Regression Coefficients, Troy Alden Wynn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Though the least squares technique has many advantages, its possible limitations as applied in the atmospheric sciences have not yet been fully explored in the literature. The assumption that the atmosphere responds either in phase or out of phase to the solar input is ubiquitous. However, our analysis found this assumption to be incorrect. If not properly addressed, the possible consequences are bias in the linear trend coefficient and attenuation of the solar response coefficient.

Using USU Rayleigh lidar temperature data, we found a significant phase offset to the solar input in the temperatures that varies ±5 years depending on …

Identifying Motivations To Encourage Women To Adopt Positive Financial Behaviors, Megan E. Rowley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Seventeen women between the ages of 25 and 54 who self-identified as having made a positive financial change within the past two years were interviewed in four focus groups. Participants were asked to identify their motivations for financial behavior change.

The analysis of this research data indicated the participants in this study progressed through the stages of change in Prochaska's Transtheoretical Model while making personal financial changes. Factors such as emotion, family influence, and life transition helped many women move from earlier stages (Precontemplation, Contemplation) to later stages (Preparation, Action) of change. Although participants utilized a wide variety of first …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The present study examined the factor structure of the Penn State Worry Questionnaire (PSWQ), the Student Worry Questionnaire-30 (SWQ-30), the Anxious Thoughts Inventory (AnTI), the Ruminative Responses Scale (RRS), and the Rumination-Reflection Questionnaire (RRQ). The present study also examined the measurement invariance between men (n = 186) and women (n = 316) in a university sample. Different models for each measure were identified through a review of the literature, and the models were examined through confirmatory factor analyses. The best-fitting models for each measure were retained for subsequent model modification to improve fit and for invariance testing across …

The Effects Of Teaching Prefix Meaning And A Strategy To Derive Word Meaning On A Prefix Vocabulary Test And Sentence Comprehension Test For Middle School Students With Learning Disabilities, Shannon K. Harris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Previous researchers have concluded that there is a need for determining how vocabulary instruction effects vocabulary comprehension and reading comprehension for young learners. Researchers have implemented morphemic strategies in various studies to identify effective methods for vocabulary instruction. In the present study, four prefixes were taught to students with disabilities to extend vocabulary research by using a morphological approach with a focus on prefix instruction. In addition students were taught how to combine the meaning of a prefix to the meaning of a root word. Data patterns indicate an increase in students' ability to provide definitions for prefixed words while …

Residential Landscape Water Check Programs: Exploring A Conservation Tool, Diana T. Glenn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In response to drought and regional growth in the arid western United States, urban water demand management is increasingly important. Single family residences use approximately 60% of their water consumption to irrigate landscapes often in excess of plant water requirements. This study utilized a quasi-experimental design to investigate outdoor water consumption and assess the effectiveness of a landscape water check conservation program. Study objectives included describing a contextualized landscape system to reveal variables influencing water use, identifying better ways to evaluate landscape water use, and more effectively targeting and delivering water conservation programs.

The study was conducted during the 2004 …

Parental Attitudes And Perceptions Related To Their Children's Physical Activity And Eating Patterns, Megan Leatham Dubois

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Children's physical inactivity and poor eating patterns have received a great deal of attention in our country and worldwide. Studies have been conducted to identify determinates related to children's physical activity and eating patterns and to identify strategies for promoting positive behaviors. Parental support is a well-accepted determinate of children's physical activity and eating patterns. However, little qualitative research has been done to determine parental attitudes and perceptions related to this critical role.

First, the study sought to gain a greater understanding of parental perspectives on their children's physical activity and eating patterns. Second, the study examined parental attitudes and …
