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…

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…

School adjustment is an important factor in children's, and research attributes an important role to the quality of the teacher-student relationship in predicting more favourable school adjustment. The purpose of this study is to expand our knowledge of the relationship between teacher-student relationship quality and school adjustment (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…

There are large differences in expulsions and suspensions on the basis of race starting in preschool and divergent explanations for their cause. The current study explores how developmental methodology can shed light on this vexing issue. We leverage two measures: (1) childcare provider complaints about children's behavior and their recommended…

The current paper uses data collected from a publicly available, nationally representative data set to examine the effects of TV viewing and video gaming on adolescent behavioral problems and cognitive achievement. Results revealed that extended hours of TV viewing were associated with greater anxiety/depression and antisocial problems. On the…

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…

This study explored negative emotional, behavioral, and academic performance outcomes for highly mobile students and potential protective factors. Participants were fourth and fifth-grade students (N = 647, 51% male) from three schools with low socioeconomic status, highly mobile student populations within a large, suburban school district in the…

Background: It has become increasingly important to shift education research and programming from a deficit focused perspective to a positive youth development perspective in order to identify and promote factors that support students' positive functioning and outcomes. One outgrowth of positive youth development is Positive Mental Health (PMH),…

Positive behaviors are essential for individual student success as well as an overall positive school climate. Students with problem behaviors are at risk for lower academic achievement and poor social skills. Schools with high incidents of problem behaviors are at risk for a negative school climate. School-wide positive behavior interventions and…

This study investigated how two aspects of the classroom environment (teachers' emphasis on mastery goals and descriptive norms (i.e., the average student disruptive, prosocial, and achievement-related behavior in a classroom), moderated the relationship between student behaviors and coolness. The sample included 976 students nested in 54 fifth-…

Depression, anxiety, and stress are common mental health problems among adolescents. Cross-sectional and longitudinal studies have found that students who suffer from mental health problems (e.g., ADHD, anxiety, or depression) tend to manifest school and social problems. It is urgent to identify and intervene early to help children with mental…

Causal search algorithms have been effectively applied in different fields including biology, genetics, climate science, medicine, and neuroscience. However, there have been scant applications of these methods in social and behavioral sciences. This article provides an illustrative example of how causal search algorithms can shed light on…

The current study evaluated bidirectional associations between mother and father positive parenting and child effortful control. Data were drawn from 220 families when children were 3, 4, 5, and 6 years old. Parenting and effortful control were assessed when the child was 3, 4, and 5 years old. These variables were used to statistically predict…

Self-regulation is an essential ability of children to cope with various developmental challenges. This study examines the developmental interplay between emotional and behavioral self-regulation during childhood and the relationship with academic achievement using data from the longitudinal Millennium Cohort Study (UK). Using cross-lagged panel…
