This study aimed to understand how the COVID-19 pandemic impacted the stress levels and life satisfaction of individuals with disabilities and what role social support plays in mitigating these impacts. Data from individuals with disabilities (n = 600) were extracted from a larger international cross-sectional survey study. Regression analyses…

In this dissertation, I use data from Chile to study the determinants of schooling trajectories. Chapters 1 and 2 focus on higher education, Chapter 3 on secondary education, and Chapter 4 on teachers. Chapter 1 explores the role of a socio-emotional ability, self-efficacy, in understanding why students with comparable qualifications transit…

Although studies have investigated educational attainment of groups of students professing low and high educational self-expectations, groups of noncommittal students, rather than being studied as a discrete group, have been treated as missing and ignored. This study investigated the differences between students of noncommittal, low, and high…

This study investigates the contribution of personality traits (HEXACO traits and Schizotypy) and social status dimensions (sociometric and perceived popularity) in understanding boys' and girls' respective academic achievement. The sample included 163 elementary school students from Serbia, aged 14-15 (87 girls and 76 boys). Regression analysis…

A well-established empirical association exists between family background and children's educational attainment. Studies have shown the importance of parental education for not just children's educational outcomes but also other behavioral, and health outcomes. In this paper, data collected by African Population and Health Research Center in 2012…

We tested theories of links between musical expertise and language ability in a sample of 6- to 9-year-old children. Language ability was measured with tests of speech perception and grammar. Musical expertise was measured with a test of musical ability that had 3 subtests (melody discrimination, rhythm discrimination, and long-term memory for…

This study employed hierarchical linear modeling to investigate the student- and school-level factors associated with the secondary mathematics achievement of English language learners (ELLs) and non-ELL students among a nationally representative sample of ninth graders in the United States. While certain characteristics, such as socioeconomic…

This study aimed to identify variables that may influence English Language Learner reintegration/exit rates from special education. It examined the variables of parental participation, English Language Learner status, and socioeconomic status. A correlational research design using secondary data analysis of an existing data set was conducted. A…

Half of kindergarten teachers split children into higher and lower ability groups for reading or math. In national data, we predicted kindergarten ability group placement using linear and ordinal logistic regression with classroom fixed effects. In fall, test scores were the best predictors of group placement, but there was bias favoring girls,…

Research suggests that youth with more financial and social resources are more likely to have access to mentorship. Conversely, the rising star hypothesis posits that youth who show promise through their individual successes are more likely to be mentored. Utilizing a nationally representative sample (N = 4,882), we tested whether demographic…

The Home Learning Environment (HLE) focuses on everyday learning habits in families to support children's competency development. In this study, we used multitrait-multimethod (MTMM) analyses to compare two theoretical dimensions and three methods for assessing the HLE and their associations with linguistic and mathematical competencies of…

Background: Socioeconomic status (SES) is the most accurate predictor of academic performance in US schools. Third-grade reading is highly predictive of high school graduation. Chronic physical activity (PA) is shown to improve cognition and academic performance. We hypothesized that school-based PA opportunities (recess and physical education)…

Background: Child development and life outcomes are partly linked to prenatal and maternal conditions such as mother's age at birth. Thus, the issue of teenage motherhood has attracted significant concern from researchers and policymakers because of its potential implications for children. The existing literature on effects of teenage motherhood…

In this article, we analyze symbolic and non-symbolic numerical abilities of parents in order to understand whether these are predictors of children's numerical skills, considering basic symbolic, non-symbolic, and formal math skills (i.e., written calculation). A battery of cognitive and math tasks was administered to a sample of 83 children with…

This four-wave longitudinal study examined bidirectional associations among pupils' social status (preference and popularity) and teacher-child relationship characteristics (quality, support, satisfaction, and conflict) in special education. Participants included 586 pupils (86% boys) initially attending Grades 4 and 5 (M[subscript age Wave 1] =…
