Academic attainment is a core education policy priority. Wellbeing is recognized as critical for adolescent development, and is linked to academic attainment. Yet research with adolescents primarily focuses on life satisfaction or overall wellbeing, despite differentiating conceptually between two wellbeing components "feeling" good…

Teachers' knowledge of students' mathematical thinking is a growing area of research in mathematics education. The literature has reported plentiful evidence of the interplays between teachers' mathematical knowledge and their knowledge of students' mathematical thinking. The present study builds on this body of work to explain how such interplays…

The study aims to examine the relationship between anxiety and psychological needs of high school students during the COVID-19 pandemic period. The fact that the COVID-19 virus poses a threat to mental health as well as physical health, the effects of the pandemic period on the psychological needs and anxiety level of adolescents, especially in a…

Scientists have warned about climate change since the 1950's. Anthropomorphic conditions, such as patterns of personal consumption, have amplified the impacts of climatic shifts. Educational campaigns that promote sustainable consumption could potentially mitigate the environmental impacts of overconsumption. While this pattern seems to be…

We used a large state-wide sample of adolescent students in 8th, 10th, and 12th grades (N = 58,689) to examine the predictive value of screen time on bullying victimization, as well as its interaction with age by gender, including transgender and gender nonconforming identities. Participants were majority boys/men (52.3%), heterosexual (88.1%),…

Dimensional comparisons (i.e., comparing own performances across domains) may drive an increasing differentiation in students' math and verbal self-concepts over time, but little longitudinal research has directly tested this assumption. Using cross-sequential data spanning Grades 1-12 (N = 1069, ages 6-18, 92% White, 2% Black, 51% female,…

The construct of belonging has been studied in many marginalised student groups yet has been understudied among students with intellectual disability. The present study used a large dataset from the United States to quantitatively investigate the construct of belonging among 7th to 12th grade students with the educational classification of…

Psychosocial skills are variables related to human behavior, beliefs, and attitudes and shape social interactions, learning processes, academic achievements, and general goal-directed behavior. Psychosocial skills seem particularly important during the adolescent period when large changes in goal setting, learning attitudes, and ability…

We investigated performance levels on conducting continuous two-footed jumping of preschool children (4 years old) to high school students (16 years old) to clarify the developmental progression and sex differences in motor coordination and agility. In total, 450 children (boys: 227; girls: 223) participated in this study. We set 10 obstacles to…

Most literature on youth focuses on prominent issues of bullying/cyber abuse, dating and relationship issues, and mental health concerns for children and adolescents; however, specific to preadolescence, little is written in comparison due to the implication that the transition between the two life stages are well blended. However, the question…

Previous research on identity development among adolescents has focused on the processes involved. However, it is unclear how the sense of identity (synthesis and confusion) develops and how it relates to life satisfaction. This study aims to examine the relationship between sense of identity and life satisfaction among Japanese youth living in…

Piaget's theory of stage structure is synonymous with discussions involving cognitive development. As with any theoretical model, researchers inevitably and rightly seek to affirm and/or contest the elements of the model presented. In this comparative study, students' performance across three hands-on engineering tasks for two distinct student…

Many children experience challenges with school mathematics during the transition from primary to secondary education, with several studies documenting a decline of performance, motivation, and self-efficacy. In order to understand how early adolescents construct their mathematical identities during this transition, this study explores, along the…

Suicide continues to be a considerable health risk among adolescents and is the second leading cause of death among adolescents between the ages of 10 and 24. Middle school-aged adolescents may be at a heightened risk for suicide, as middle school can be rife with intrapersonal and interpersonal stressors. One such stressor may be sexual activity…

Middle school brings rapid developmental changes for adolescents, and parent engagement is as essential as ever. However, what worked for parent-teacher partnerships in elementary school doesn't fit so well in middle school. Adolescents are building their autonomy, and teachers must help empower parents' efforts to bolster students as independent…
