Structural equation modelling was used to investigate the predictive associations between kindergarten developmental, socio-behavioural, and biotic influences on third grade achievement among a nationally representative sample of low-SES children. The findings validate the understanding that developmental and learning trajectories start early in…

A multisite cluster-randomized trial (by school) was conducted to examine the effects of a combined mental health literacy and dialectical behavior therapy skills program implemented by teachers on three protective factors related to social and emotional well-being. The sample of eight schools that were randomly assigned to intervention included…

Early fine motor ability is significantly associated with later achievement, even after controlling for typical child-level predictors of school outcomes. Previous longitudinal studies have confirmed this but typically have not included low-income, at-risk populations. Research has distinguished two different aspects of fine motor skills: those…

Background and Context: Educators and researchers are interested in building the computational thinking (CT) skills of K-12 students. However, the availability of language-agnostic assessments for lower elementary graders remains limited. Objective: We present preliminary insights into the reliability and validity of the Computational Thinking…

This study examined the impact of a commonly adopted elementary universal social-emotional learning program, Second Step, on student social-emotional and academic outcomes following 2 years of implementation. The cluster-randomized wait-list control trial included 61 schools, 321 teachers, and 8,941 early elementary students across 2 states, with…

Evidence suggests that children's expectations for how their teacher responds to students' aggression moderate concurrent links between peer victimization and adjustment. This study extends this work by examining these associations longitudinally. Youth (N=366; 196 girls; M[subscript age]=9.25years) reported on their teacher's use of five…

At school entry, girls are rated by teachers as more competent on measures of social skills than boys. It is less clear if this higher rating is stable or grows over time. To address this question, multiple group curve of factors models investigated gender-specific growth trajectories across seven waves of measurement in a large, longitudinal…

Direct instruction is required in the use of different comprehension skills in order to advance students' ability to independently comprehend texts. Being able to make connections is an important reading comprehension strategy which allows students make meaning of what they are reading. The aim of the current study was to investigate the…

With a focus on within-person effects, this study investigated mutualism among academic skills (reading, math, science) and between those skills and verbal working memory in a general population sample and groups with high or low skills from Grades 2 to 5 (2010-2016, N = 859-9040, age 6.27-13.13 years, 49% female, ethnically diverse). Mutualism…

Children's positive perceived motor competence (PMC) provides motivation for physical activity. Theoretically young children (<8 years) have inflated PMC but as children cognitively develop, perceptions are hypothesized to decrease. This study investigated strength of PMC association over time, whether any change was negative (i.e. PMC…

The "Developing Inclusive Youth" program is a classroom-based, individually administered video tool that depicts peer-based social and racial exclusion, combined with teacher-led discussions. A multisite randomized control trial was implemented with 983 participants (502 females; 58.5% White, 41.5% Ethnic/racial minority; M[subscript…

The aim of this study was to evaluate relationships among the primary school students' social connectedness to parents, teachers and peers, and their career and talent development self-efficacy (CTD-SE). CTD-SE encompasses talent development, career exploration and the acquisition of good work habits. Results suggest that the connectedness with…

The purpose of this study is to determine the third and fourth grade primary school students' metacognitive awareness and perception of their decision-making skill and the relationship between them. The study employed the relational survey model. The population of the study is comprised of the third and fourth grade primary school students…

Learning coding during early childhood is an effective way for children to practice computational thinking. Aspects of children's motivation can increase the likelihood that children approach computational thinking activities with enthusiasm and deep engagement. Gender inequities may interfere with children's readiness to take advantage of…

Ample of knowledge leads to positive attitude. Knowledge is an important tool that promotes attitude changes. Knowledge and Attitude of students towards safety is important because action of a person depends on believe. Unsafe actions of students are caused most of injuries and harms. It is important to minimize such harms by knowledge. Present…
