Background: Within the same school class, it is usual to find children who differ in age by almost a full calendar year. Although associations between being relatively young and poor academic outcomes are well documented, and relatively consistent, the associations between being relatively young and psychosocial outcomes are less clearly…

Children's low academic skills are associated with a variety of behavior problems and maladaptive outcomes throughout childhood and adulthood. Given the prevalence of behavioral disorders is approximately 19% of all US children, understanding of the mechanisms through which academic achievement and externalizing behavior problems interact can…

This dissertation is a three-piece dissertation, including two empirical research (Chapter 1 and Chapter 2) and a methodological improvement of prior work (Chapter 3), to address issues of the effects of approaches to learning on academic achievement in childhood and power analysis for a three-level model in meta-analysis. Approaches to learning…

This one-year longitudinal study examined the moderating effect of perceived social support from school-based Gay-Straight Alliances in the associations between homophobic cyberbullying involvement (i.e., victimization, bystanding) and academic outcomes (e.g., classroom misconduct, school readiness, academic performance, absenteeism, school…

As academic standards for incoming kindergarten students at Morris Early Childhood Center (MECC), in the Milford School District, increase, a significant obstacle to student achievement has emerged. The deficiency of social and emotional skills among MECC students has increasingly impeded school staff from focusing on instruction due to the…

The purpose of the study was to characterize the relationships between behavior problems, academic achievement, and loneliness of students in the upper and lower thirds of a social skills classification. Participants were 733 students (359 boys and 374 girls) ages 9 to 14 years, 642 without learning disabilities (LDs) and 91 with LDs. Their…

Some of the worst long-term outcomes of children are associated with the presence of both externalizing behavior and low academic achievement. Additionally, trajectories of externalizing problem behavior have shown that when children enter kindergarten with problem behavior, it tends to persist and is often associated with low academic…

Understanding achievement and discipline trajectories of Latinx students is critical given disproportionate dropout/pushout rates of Latinx students from schools across the U.S. Using a Critical Race Theory framework, the current study examined longitudinal associations amongst a sample of (N = 1672) Latinx youths' school readiness at kindergarten…

Externalizing behavior and low academic performance present key developmental challenges for school-age children, with the potential for these domains to predict each other over time, leading to worsened outcomes. Yet, previous studies have yielded inconsistent conclusions about the directional pathways between externalizing behaviors and academic…

Classroom incivility is a critical concept relating to the academic and psychosocial well-being of children and youth. However, there has yet to be research investigating whether there are social benefits to this behavior in early adolescence. Therefore, the goal of this study was to explore the relationship between classroom incivility and…

Introduction: The current school is strongly focused on student performance. Each student faces a large number of learning tasks, which place considerable demands on them, arouse in them a different degree of interest, evoke a different degree of commitment to work, are associated with different expectations or have a different degree of…

Background: Bullying has a profound and enduring impact on academic achievement. However, there is a lack of clarity surrounding the specific mechanisms of this relationship. Aims: This study examined the link between bullying at age 9 and Numeracy/Literacy achievement at age 15 to determine if this relationship is partially or fully explained by…

Background: Adolescents' school engagement, mental health, and substance use have been major concerns during the COVID-19 pandemic, particularly given disruptions to school instruction. We examined how the instructional setting was associated with academic and health-related outcomes within an adolescent cohort followed during the pandemic.…

Understanding executive functions (EFs) development is of high value to global developmental science. Recent calls for a more inclusive and equitable developmental science argue that tasks and questionnaires that are developed using only a subset of the population are not likely to be appropriate for EFs measurement in global contexts unless…

Due to the diversification of school systems, schools are being challenged to engage in more culturally responsive practices to meet the needs of diverse students. Therefore, this study utilized Gay's (2002) model of culturally responsive teaching to assess the relationship between sociocultural factors and the academic competence and mental…
