Foundations of statistics research aims to establish fundamental principles guiding inference about populations under uncertainty. It is concerned with the process of learning from observations, notions of uncertainty and induction, and satisfying inferential objectives. The growing interest in predictive methods in high-stakes fields like…

This dissertation address two significant challenges in the causal inference workflow for Big Observational Data. The first is designing Big Observational Data with high-dimensional and heterogeneous covariates. The second is performing uncertainty quantification for estimates of causal estimands that are obtained from the application of black box…

This study has three primary objectives. First to provide insight into possibilities for moderation/mediation analysis in education research by discussing analytical methods based on the counterfactual and developed in other disciplines. Second is to highlight specific issues related to mediation and the estimation of effects when the outcome is…

Well-educated and informed elementary educators provide the highest of quality instruction to elementary students. Elementary educators are expected to provide instruction from all academic subjects throughout the school day. As standardized testing continues to be a priority in U.S. classrooms, educators must be prepared to continue to deliver…

The demographic composition of America's population has changed significantly over the past several decades which is reflected in classrooms that are culturally and linguistically more diverse. In particular, the rapidly growing population of non-native English speaking students has highlighted the need for language instruction programs to…

The purpose of this hermeneutic phenomenological was to describe teacher efficacy in the lived experiences of secondary teachers actively engaged in the instructional coaching process. The theoretical framework guiding this study was Albert Bandura's (1992) social cognitive theory as it expounds upon the role efficacy plays in human agency as it…

Response to Intervention (RTI) programs are designed to support students at risk of failing in school due to academic or behavioral problems. When RTI programs are applied inconsistently due to teachers' resources or knowledge, students may be wrongly identified for special education services. The purpose of this qualitative bounded descriptive…

The idea of data use as an educational reform strategy has gained significant traction in recent years, but there is limited research that illuminates what actually happens when teachers use data in practice. This study investigates the ways a group of middle school mathematics teachers used data in their classrooms and as part of an action…

This basic qualitative research study explored the lives of 14 elementary teachers in their classroom environment to answer two central research questions which are: what coping strategies do teachers find most effective and what coping mechanisms provided by administration helps them cope with classroom stress? Data were collected through…

The purpose of this phenomenological study was to examine how teachers from various levels of technology self-efficacy perceive and implement technology within their specific classroom. Using a qualitative approach, I explored four public schools from a medium to large-sized school district in the Southeastern United States. The Technology…

Critical analysis of the literature reveals that many questions about the knowledge and practice of mathematics teacher educators (MTEs) remain in need of further research: how do they know what to teach; how do they learn how to teach teachers; how do they prepare to teach their courses; how does the research on teacher education inform their…

In this dissertation, I explored the lives of 10 children who were diagnosed with a language disorder. The children were enrolled in a therapeutic half-day speech-language preschool classroom for 3- and 4-year-old children within a public-school system in the rural Southeast. The research included a 15-week mini-ethnographic case study utilizing…

Young students' genre knowledge and learning have been of interest to literacy researchers for some time. How students learn and recognize genres, how they deploy them, how they learn the circumstances under which to deploy particular genres are key concerns for literacy educators and researchers. While the field of Composition Studies has long…

This dissertation examines the role of conceptions of data's value in data practices. Based on a study of three small teams of scientists carrying out ecological research at a biological station, my study addresses the following main question: How do scientists conceive of the value of their data, and how do scientists enact conceptions of value…

The purpose of this qualitative case study is to identify how PLCs influence the high school English teachers' practice in response to key instructional shifts within teaching standards in the Southwest United States. Legislation from the last two decades puts expectations in place that raise the bar for American students and their teachers…
