In response to the high school dropout crisis, which comes with great economic and social costs, early warning systems (EWSs) have been developed to systematically predict and improve student outcomes. The purpose of this study is to evaluate different statistical and machine learning methods to predict high school student performance and improve…

The purpose of this study was to examine the effects of proactive student-success coaching, informed by predictive analytics, on student academic performance and persistence. Specifically, semester GPA and semester-to-semester student persistence were the investigated outcomes. Uniquely, the community college focused the intervention on only…

Community college transfer students often experience "transfer shock" at receiving four-year institutions, which includes a variety of academic, social, and institutional challenges associated with the first-year transfer experience. Research has demonstrated that first-year program interventions can facilitate the transition of…

Behavioral feeding difficulties occur at a high rate in children with autism spectrum disorders (ASD) and can have a serious impact on their overall health and development. Although there are a number of studies demonstrating effective strategies for addressing behavioral feeding difficulties in children with ASD, the majority of them have been…

This dissertation examines the college experience of traditional-age community college students. The objectives of this dissertation are threefold. To explain early exits from higher education, the first manuscript integrates Tinto's interactionalist theory and Coleman's theory of social capital to describe the mechanisms through which…

Community colleges are a crucial channel for achieving postsecondary education success, especially for minority and nontraditionally aged students. Nonetheless, community colleges are inadequate to meeting national goals for postsecondary educational attainment. Most notably, the lack of a strong guidance of academic interventions stifles a…

This dissertation describes a design for training, in accordance with probability judgment heuristics principles, for the Angoff standard setting method. The new training with instruction, practice, and feedback tailored to the probability judgment heuristics principles was called the Heuristic training and the prevailing Angoff method training…

Stochastic understanding of probability distribution undergirds development of conceptual connections between probability and statistics and supports development of a principled understanding of statistical inference. This study investigated the impact of an instructional course intervention designed to support development of stochastic…

The Texas Statewide Youth Leadership Forum (TXYLF) provides self-advocacy training to high school youths with disabilities. TXYLF is an enhanced version of the Youth Leadership Forum (YLF) that is comprised of an initial five day training, a nine month support phase, regional YLFs, and the opportunity for participants to return to the five day…

An existing data set for a sample of 3rd grade students was used to determine the relationship between performance during a reading intervention and short-term achievement test outcomes, and long-term risk status. Students participated in a reading intervention, one-on-one practice with a trained adult, during which weekly curriculum based…

This study examined the effects of the "READ 180"[R] program on the reading achievement levels of fourth grade students who participated in the "READ 180"[R] program (Scholastic Incorporated, 2005) compared to fourth grade students who were reading below grade level but who were not participating in the "READ 180"[R]…

In an effort to improve academic performance for students receiving special education services, a large urban school district in Tennessee has implemented Integrated Service Delivery Model. The purpose of this study was to compare the performance of students receiving instruction in self-contained classrooms to the performance of students…

In this study, the author examined the relationship of probability misconceptions to algebra, geometry, and rational number misconceptions and investigated the potential of probability instruction as an intervention to address misconceptions in all 4 content areas. Through a review of literature, 5 fundamental concepts were identified that, if…

Despite having drawn from empirical evidence and cumulative prior expertise in the formulation of research questions as well as study design, each study is treated as a stand-alone product rather than positioned within a sequence of cumulative evidence. While results of prior studies are typically cited within the body of prior literature review,…

An experimental study was conducted to investigate the effects of an Employee Wellness Program on physiological risk factors, job satisfaction, and monetary savings in a South Texas University. The non-probability sample consisted of 31 employees from lower income level positions. The employees were randomly assigned to the treatment group which…
