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. …

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 …

The purpose of this longitudinal study was to examine generativity development among college student leaders who mentor. There were four research objectives: (a) the nature of change in generativity among college student leaders who serve as a Leadership Mentor for three years, (b) the predictive relationship between generative concern and generative behavior at Time One, Time Two, and Time Three, (c) the moderating effect of having been or currently being an informal or formal mentee on generativity levels and generativity development, and (d) the influence of participant sex (i.e., male or female) on generativity level and generativity development. Participants completed …

Evaluation Of Modern Missing Data Handling Methods For Coefficient Alpha, Katerina Matysova

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

When assessing a certain characteristic or trait using a multiple item measure, quality of that measure can be assessed by examining the reliability. To avoid multiple time points, reliability can be represented by internal consistency, which is most commonly calculated using Cronbach’s coefficient alpha. Almost every time human participants are involved in research, there is missing data involved. Missing data means that even though complete data were expected to be collected, some data are missing. Missing data can follow different patterns as well as be the result of different mechanisms. One traditional way to deal with missing data is listwise …

The Development Of A Situational Judgment Test To Assess Collegiate Judgment: A Pilot Study, Jared Stevens

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

Traditionally, colleges and universities have focused primarily on cognitive predictors (e.g., ACT/SAT scores, high school GPA), and have struggled to find an accurate and objective way of measuring non-cognitive skills, often resorting to personality measures or interviews, or deciding not to measure them at all. Recently, there has been a push for alternative forms of student selection that result in less adverse impact and do not ignore important skills and traits that are necessary to be successful in college (Peeters & Lievens, 2005; Atkinson, 2001).

Growing evidence suggests Situational Judgment Tests (SJTs) may be one way to achieve this goal. …

The Influence Of Previous Subject Experience On Interactions During Peer Instruction In An Introductory Physics Course: A Mixed Methods Analysis, Judy A. Vondruska

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

Over the past decade, peer instruction and the introduction of student response systems has provided a means of improving student engagement and achievement in large-lecture settings. While the nature of the student discourse occurring during peer instruction is less understood, existing studies have shown student ideas about the subject, extraneous cues, and confidence level appear to matter in the student-student discourse. Using a mixed methods research design, this study examined the influence of previous subject experience on peer instruction in an introductory, one-semester Survey of Physics course. Quantitative results indicated students in discussion pairs where both had previous subject experience …

Tacit Cultural Knowledge: An Instrumental Qualitative Case Study Of Mixed Methods Research In South Africa, Debra Rena Miller

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

Notwithstanding the dramatic expansion of mixed methods research, research methodologies, methods, and findings are culturally situated. Problematically, studies conducted outside the global north often embrace canonical methodologies aimed at understanding concepts more explicit than tacit. Learning about the needs of researchers and participants in South Africa may bring to light taken-for-granted assumptions in Anglo-American orientations of mixed methods. Hence, the purpose of this study is to explore aspects of tacit cultural knowledge that contextualize mixed methods research in South Africa.

In-person interviews among South African professors as well as a corpus of books, sections, journal articles, and theses informed the …

Can Analyzing Spatial Relationships Through Geographically Weighted Regression Improve Our Understanding Of Low School Attainment? A Gis-Based Analysis Of Census And Acs Data, William England

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

In this study I present a relatively new technique for analyzing a recurring problem in our communities. Using a set of innovative and relatively new modeling methods, I demonstrate ways in which it is possible to directly account for, capture, and visualize the spatial variability in the relationships between U.S. Census data from 1990 and the recent low-school-attainment landscape in both the Omaha and Lincoln Public School (OPS) districts in Omaha and Lincoln, NE. Low school attainment in adults is a correlate of a host of troubling health and economic factors, which, in turn, have an impact on a child's …

The Adoption Of Mixed Methods In China: An Exploratory Instrument Design, Yuchun Zhou

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

Mixed methods is “the third research paradigm” and a methodology along with traditional quantitative and qualitative methodologies (Johnson & Onwuegbuzie, p.14). It is at the expansion/diffusion stage of development where researchers are most interested in how this method is adopted across disciplines and countries. However, very little literature is found regarding the use of mixed methods in non-Western cultural contexts, such as East Asia. Hence, the current study aimed to explore the expansion of mixed methods in an underrepresented population, China, a non-Western context and developing country.

The study employed an exploratory instrument design to investigate Chinese scholars’ decisions of …

Psychosocial Food-Related Behavior And Food Intake Of Adult Main Meal Preparers Of Food For 9-10 Year-Old Children Participating In Icook, A Five-State Childhood Obesity Pilot Prevention Study, Ashley A. Miller

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

Understanding adult outcomes of programs aimed at childhood obesity prevention is necessary because parents/caregivers are the most important influence on a child’s physical activity and eating habits. Based on the principles of the social cognitive theory, the iCook 4-H pilot study taught dyads consisting of 9-10 year-old children and their primary meal preparers cooking skills, healthy shopping and meal habits, and easy ways to incorporate physical activity as a family. The program took place in five states, Maine, Nebraska, South Dakota, Tennessee, and West Virginia. In each state, adult-youth dyads (n = 54) were recruited by 4-H programs and nutrition …

Comparability Of Online And Paper/Pencil Mathematics Performance Measures, John L. Moon

The purpose of this study was to investigate the relationship between student mathematics performance of 4^th, 8^th, and 11^th grade students in Nebraska and the mode of test administration, online and paper-pencil. Schools were allowed to select the mode of test administration for their school with some exceptions for students needing accommodations. This resulted in four test groups, namely students taking the online tests in schools selecting paper or online assessments along with students taking the paper-pencil tests in schools selecting paper or online assessments. Since the students in the study were clustered within schools, …

Making Room For Formative Assessment Processes: A Multiple Case Study, Rob Mcentarffer

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

This qualitative instrumental multiple case study (Stake, 2005) explored how teachers made room for formative assessment processes in their classrooms, and how thinking about assessment changed during those formative assessment experiences. Data were gathered from six teachers over three months and included teacher interviews, student interviews, participant-observation notes, videos of classroom experiences, and classroom artifacts. These data were analyzed using a category construction method (Merriam, 2009) that involved open coding, axial coding, and finally a cross-case analysis that grouped axial codes according to themes relating to the two research questions. Four case studies describe the process of co-created work with …

A Pilot Study: The Use Of A Survey To Assess The Food Knowledge Of Nutrition Students At Various Levels Of Nutrition Education, Chante Chambers

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

A working definition of a concept known as ‘food literacy’ encompasses using basic food preparation knowledge that has been learned, understood, and practiced to make better food decisions. To advance these skills for client service, a post-secondary nutrition program would need to include objectives that allow application of knowledge. For this reason, the purpose of this study was to determine the difference in knowledge and application among students in 100, 200 and 400 level college nutrition course(s). A survey was developed to measure the food knowledge of these college students as they prepare for careers as health care professionals. The …

An Investigation Of The Potential Use Of Advanced Placement Examination Scores In The College Admission Of Transfer Students, Andrew Callahan Dwyer

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

Faced with making college admission decisions on an increasingly large number of applicants, many higher education institutions have begun to consider using additional information to assist with those decisions. Unlike college admissions practices for the population of first-time freshmen, however, admission practices for the population of transfer students have been largely ignored in the literature. There is evidence that the transfer student population is growing and will likely continue to grow for the foreseeable future, which emphasizes the need for colleges and universities to find additional suitable information to use in transfer student admission. Using data from the University of …

Evaluating Measurement Invariance With Censored Ordinal Data: A Monte Carlo Comparison Of Alternative Model Estimators And Scales Of Measurement, Natalie A. Koziol

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

Evaluations of measurement invariance provide essential construct validity evidence. However, the quality of such evidence is partly dependent upon the validity of the resulting statistical conclusions. The presence of Type I or Type II errors can render measurement invariance conclusions meaningless.

The purpose of this study was to determine the effects of categorization and censoring on the behavior of the chi-square/likelihood ratio test statistic and two alternative fit indices (CFI and RMSEA) under the context of evaluating measurement invariance. Monte Carlo simulation was used to examine Type I error and power rates for the (a) overall test statistic/fit indices, and …

Improving Irt Parameter Estimates With Small Sample Sizes: Evaluating The Efficacy Of A New Data Augmentation Technique, Brett P. Foley

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

The 3PL model is a flexible and widely used tool in assessment. However, it suffers from limitations due to its need for large sample sizes. This study introduces and evaluates the efficacy of a new sample size augmentation technique called Duplicate, Erase, and Replace (DupER) Augmentation through a simulation study. Data are augmented using several variations of DupER Augmentation (based on different imputation methodologies, deletion rates, and duplication rates), analyzed in BILOG-MG 3, and results are compared to those obtained from analyzing the raw data. Additional manipulated variables include test length and sample size. Estimates are compared using seven different …

The Impact Of Teaching Presence In Intensive Online Courses On Perceived Learning And Sense Of Community: A Mixed Methods Study, Elizabeth Laves

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

This mixed methods concurrent triangulation design study was predicated upon two models that advocated a connection between teaching presence and perceived learning: the Community of Inquiry Model of Online Learning developed by Garrison, Anderson, and Archer (2000); and the Online Interaction Learning Model by Benbunan-Fich, Hiltz, and Harasim (2005). The objective was to learn how teaching presence impacted students’ perceptions of learning and sense of community in intensive online distance education courses developed and taught by instructors at a regional comprehensive university.

In the quantitative phase online surveys collected relevant data from participating students (N = 397) and selected instructional …
