This dissertation includes three individual articles that explore the relationship between witnessing bullying and defending behavior among students who are bystanders of bullying. Chapter One provides the rationale and purpose of this dissertation and an overview of the three articles that comprise it. Chapter Two employed a cross-sectional…

This study investigates the effect of a female STEM professional mentoring program on perceptions among K-12 female participants. Led by STEM professionals, the program aims to enhance understanding of STEM careers. The findings reveal significant changes in the K-12 females' attitude and career aspirations towards STEM following their involvement…

Given the worldwide shortfall of engineers that threatens innovation and global stewardship, educators and industry must find ways to engage and prepare the next generation of engineers. To attract and train candidates to fill global needs, researchers need to expand engineering career pathway perceptions for students of all ages. Engineering…

This ethnographic study explores the crucial role of family engagement in educational systems and the impact a human-centered design team has on students' success at an elementary school. The research addresses the historical impact of racism and colonization on student outcomes alongside the ongoing challenge of narrowing the opportunity gap.…

Achieving proficiency in core foundational oral language (OL), reading, and writing skills remains difficult for students with specific learning disabilities (SLD) and foundational OL difficulty (National Center for Educational Statistics, 2022). Despite evidence linking OL skills in grammar (morphosyntax, syntax) and vocabulary (semantics) to…

Special education comprises specially designed instruction, at no cost to parents, to meet the unique needs of children with disabilities (IDEA, 2017, Sec. 300.39). IDEA further states that specially designed instruction can be implemented in the classroom, in the home, in hospitals and institutions, and in other settings. Placement decisions are…

This study investigated the predictive relationship between mathematics anxiety and mathematics performance using a more sensitive measure of performance, fluency. Fourth and fifth grade students completed a seven-page packed which included a demographic questionnaire, the Mathematics Anxiety Scale for Children (MASC), a mixed math probe measuring…

Justification has received an increased emphasis in more recent years and is considered an essential component of mathematical reasoning and sense making. Despite its importance to school mathematics, the practice of engaging students in constructing justifications remains a hurdle for teachers. This mixed methods research study explores the…

The problem that prompted this qualitative case study was a continuous below proficiency level performance of the kindergarten through second-grade students in a U.S. Southern state in reading, despite response to intervention (RTI) being implemented since 2011. The purpose of the study was to explore K-2 teachers' perceptions regarding the…

Trusting relationships between teachers and students is a cornerstone of success in the classroom. As a means for continuous professional growth, teachers should have an understanding of other teachers' positive experiences with and accessible strategies for how to build these relationships. Current research is missing the narrative voices of…

Cover-Copy-Compare (CCC) has been identified as an empirically supported and socially valid intervention for promoting math fact fluency across instructional settings. However, limited research has investigated the effectiveness of CCC as a math fact fluency intervention within the setting IV environment with even fewer studies including…

Research shows that parental involvement in children's school life has a positive impact on children's academic and social success, especially for children with disabilities (CWD), and even more so for CWD in island rural communities. The involvement of parents of CWD in primary schools in rural communities in Trinidad and Tobago has not been…

Dyslexia is a reading disability that interferes with accurate and fluent word reading. Deficits in word reading may cause secondary consequences, including reading comprehension difficulties. However, despite inherent word reading problems, there are students with dyslexia who exhibit resiliency that manifests as better than expected educational…

Angle measurement is a significant topic in almost all areas of mathematics learning and also in many disciplines outside mathematics education, such as engineering and architecture. According to the literature, there are three common conceptions of angles--as union of rays, rotations, and wedges. Researchers argued that students must consider…

Over two-thirds of youth participate in a structured sport, making it a vital context in which transactional relations with cognitive development can occur. Yet, little is known about how these constructs inform one another across childhood. Most previous studies have focused on health benefits of sport participation, or on demographic and family…
