Background: Students' social emotional competencies (SECs; also known as non-cognitive skills) are the skills or knowledge that allow them to successfully navigate social and academic environments such as self-management, social awareness, and relationship skills. Research has established cross-sectional associations between SECs and student…

The purpose of this study was to observe how within-person variation in motivation, self-efficacy and academic performance scores are correlated or can be predicted. The reciprocal association between these variables was analysed through a four-wave longitudinal study and a within-person analytical approach (random intercept cross-lagged panel…

Although personal and environmental correlates of adolescents' happiness have been found, the temporal direction of these relationships is less known. The present study explored the longitudinal and reciprocal relationships between self-esteem, school adjustment, and happiness during secondary school years in South Korea. Longitudinal data of…

An explanation for the underrepresentation of women in mathematical fields is the communal goal congruity perspective; that women tend to value communal over agentic goals, perceived to not be afforded by mathematical careers. Less is known about how agentic and communal goals may interact to influence mathematical career trajectories. Analysing a…

Three-year longitudinal and concurrent associations of leadership with overt aggression, exclusion of others, effortful control (EC), popularity, unpopularity, prosocial behavior, and academic achievement were assessed in this study of Indonesian adolescents. Participants were initially assessed in the 10th grade (n = 462, 256 girls; M[subscript…

This study focuses on the disparities between the educational aspirations and expectations of high school students in the U.S., and explores why students do not expect to earn a bachelor's degree despite their aspirations. Using a national dataset and logistic/multinomial logistic regression analyses, the study identified the factors associated…

The effects of Content and Language Integrated Learning (CLIL) on students' foreign language skill development have been overestimated by previous studies, as most studies needed to have considered selection and preparation effects appropriately. We used complete survey data from a 1996-2003 cohort to investigate English skill development of N =…

In this study, the authors examined a group of related literatures that used the same large-scale nationally representative dataset with algebra achievement as the outcome to explore why results from the same dataset may differ across studies. More specially, the authors synthesized the extant research literature that utilized data from the High…

In this study, high school physics textbooks published by People's Education Press (PEP) and Educational Science Publishing House (ESP) (a total of 6 books) in China were analyzed via a self-developed scale measuring nature of science (NOS) including three first-level indicators of scientific knowledge, scientific process, and scientific…

The development of anti-racist ideology in adolescence and emerging adulthood is informed by parent socialization, parenting style, and cross-race friendships. This study used longitudinal, multi-reporter survey data from White youth and their parents in Maryland to examine links between parents' racial attitudes when youth were in eleventh grade…

According to the National College Attainment Network (NCAN, 2023), each year, thousands of high school graduates leave billions of dollars in federal student aid unclaimed because they do not complete the Free Application for Federal Student Aid (FAFSA). To holistically investigate this phenomenon, this dissertation accomplished three goals. The…

Background: Adolescent behaviors and academic outcomes are thought to be shaped by school climate. We sought to identify longitudinal associations between school climate measures and downstream health and academic outcomes. Methods: Data from a longitudinal survey of public high school students in Los Angeles were analyzed. Eleventh-grade health…

Background: Despite extensive research examining features of adolescents' ego-identity development, little research has demonstrated patterns of ego-identity development and its relationship with various individual and environmental factors that are theoretically important for identity development. Objective: The current study investigated…

The racial/ethnic disparities and average declines in science, technology, engineering, and mathematics (STEM) motivation during adolescence are worrisome. Although STEM motivational beliefs are theorized to function in conjunction with one another, the unique patterns and how they change over time for different racial/ethnic groups remain…

The association between students' academic identity and their academic outcomes has been well-established. The importance of a positive school climate has also been widely documented. However, Black males experience factors that uniquely and collectively comprise their school climate. As such, the purpose of this study was to test the extent to…
