It is estimated that less than 20% of young people worldwide are receiving the recommended 60 minutes of moderate-to-vigorous physical activity (MVPA) per day (Riley, Lubans, Holmes, & Morgan, 2014). Delaware and many other states around the country use FITNESSGRAM to assess students' overall physical fitness. The FITNESSGRAM® is a physical…

This embedded case study sought to answer the question of what obstacles and opportunities presented when a reading initiative aimed at increasing the amount of time students spent reading independently was implemented during the COVID-19 pandemic. Four embedded grade level cases from a small rural elementary school were explored over the course…

At-risk students are at risk of falling behind in contributing to tomorrow's 21st-century technological workforce unless educators address deficits early on. Scholars have indicated school librarians can raise at-risk students' self-efficacy levels and address inequity through access to technology and instruction. Nonetheless, there are…

Students who identify as transgender, non-binary, and gender non-conforming navigate multiple messages and realities under the current media and political climate. While transgender individuals are seeing greater representation in popular culture, the political arena, and other areas of power, they are still at higher risks for violence,…

Fractions are foundational for success in algebra and STEM, but they are notoriously difficult for students. In past work, two separate branches of research from psychology and math education have studied fractions knowledge using different, isolated approaches. In this dissertation, I synthesize research from both fields about proportional…

This manuscript provides information on datasets pertaining to Project KIDS. Datasets include behavioral and achievement data for over 4,000 students between five and twelve years old participating in nine randomized control trials of reading instruction and intervention between 2005-2011, and information on home environments of a subset of 442…

Eye movements provide a sensitive window into cognitive processing during reading. In the present study, we investigated beginning readers' longitudinal changes in temporal and spatial measures of eye movements during oral versus silent reading, the extent to which variation in eye movements is attributable to individual differences and text…

The purpose of this case study was to examine how the K-5 elementary alternative program All Students Can Thrive (ASCT) used student-centered learning practices to influence the whole child. There is a lack of research on K-5 elementary alternative programs, such as ASCT, and specifically those that integrate student-centered learning practices to…

Most school districts across the country continue to research how to help their students become better prepared to enter the workforce and higher education. As a result, the extent to which dynamic teaching techniques affect the success of classroom-taught material currently is not known. Much of the current literature reveals studies on teaching…

In recent years, the number of English learners (ELs) in U.S. public schools has rapidly grown, with Hispanic children accounting for more than half of Texas public school students, including pre-kindergarten and early childhood education. ELs continue to demonstrate lower reading achievement in comparison to their native English-speaking peers.…

This study emphasizes formal and informal reading development, race, and socioeconomic status as significant components of the lived experiences of four low socioeconomic Black/Brown second- and third-graders who struggled with reading. The research acknowledges historical progression of the American public education system, exploring…

Supporting students with mathematics learning difficulties (MLD) as they transition from arithmetic to algebra remains a challenge within the special education and mathematics education research communities. This dissertation includes 3 manuscripts focused on how fifth graders with MLD develop algebraic understandings related to equivalence and…

Social-emotional competence (SEC) is a set of cognitive, affective, and behavioral skills that enable an individual to engage in healthy interactions with oneself and other human beings. SEC is a critical factor for individual well-being and may also contribute to creating a more safe and caring community. SEC can develop throughout a lifetime,…

The overall aim of this grounded theory multiple-case study was to better understand how K-12 independent schools ("schools") in the United States cultivate a connection between children and adolescents ("students") and the natural world ("environment") by exploring the interplay between this connection and (a) the…

The purpose of this mixed-methods study was to examine the extent to which a digital dialogic reading intervention, shared among adult-child dyads, impacted the reading comprehension of three at-risk readers of primary school age, between six and nine. This age range was an appropriate age for assessing reading comprehension, therefore…
