This study examined whether adolescent students' externalizing behavior and prosocial behavior affects their academic achievement (i.e., school grades and standardized test scores) in two major academic domains (i.e., mathematics and German) over and above well-established determinants of school achievement (i.e., prior achievement, intelligence,…

To promote pro-environmental behavior (PEB), it is crucial to understand the drivers behind it. Studies indicate that, in addition to environmental attitudes and nature activities, interest in nature drives people to engage in PEB. However, the relationship between interest in nature and PEB is still greatly understudied among adolescents even…

We tested whether a brief self-affirmation writing intervention protected against identity-threats (i.e., stereotyping and discrimination) for adolescents' school-related adjustment. The longitudinal study followed 639 adolescents in Germany (65% of immigrant descent, 50% female, M[subscript age] = 12.35 years, SD[subscript age] = 0.69) from 7th…

While school self-concept is an important facilitator of a student's school engagement, previous studies rarely investigated whether it may also explain the change in students' school engagement during secondary school. Moreover, as social relations play an increasingly important role in adolescence, the current research distinguishes between the…

By complying with their "job", i.e., completing the tasks set for them by teachers, pupils develop their subject skills. They do this in a classroom setting where they can perceive each other regarding their abilities. Besides content learning, pupils, thus, also have to position themselves emotionally and action-practically towards the…

This book presents the first results from the third cycle of the IEA International Computer and Information Literacy Study (ICILS 2023). This study investigated how young people are prepared for life in a world where the capacity to use computers and digital information responsibly, safely, and effectively is essential. The study reports on data…

Previous studies pointed out that dealing with difficult behaviour is perceived by teachers as a major challenge in inclusive settings. However, research on the students' perception of the classroom behavioural climate (CBC) is rare. Therefore, this study aims to examine students' perceptions of CBC and to identify predictors of CBC as well as…

Research has shown that there are positive associations between students' goals and learning behavior. However, less is known about these associations for adolescent students in competency-based learning compared to adolescent students in teacher-directed learning. The current study was conceptualized with the aim of getting more in-depth…

How others behave (descriptive norm) and what they expect from us (injunctive norm) has a strong influence on how we behave. However, children and adolescents often overestimate the prevalence of negative behavior among their peers. The current study tested whether prompting peer norms for cyberbullying may foster anti-cyberbullying norms in an…

Theories of creativity and empirical evidence have highlighted the importance of autonomy as a motivational source of creativity. However, we know little about the relationship between the implicit autonomy motive and creativity. Using a multi-method multi-informant design, we investigated the relationship between implicit autonomy motives and…

Cross-age tutoring is characterised by status and age differences between tutors and tutees. Tutees are often inactive in this setting, because responsibility for effective learning is transferred to the more experienced tutors. This study focused on improving the outcomes of cross-age tutoring for tutees by providing tutors with a tutor training…

The willingness to solve conflicts without violence and to strive for a reconciliation of interests is of central significance for the continued existence of democracies. In this paper, we aim to analyze school-related determinants of adolescents' conflict behaviour. Models predicting the conflict styles of "integrating",…

Student misbehavior is a pervasive problem and may seriously affect academic achievement. Previous research hints at different effects depending on whether achievement tests or achievement judgments are used as academic outcomes. Previous research also indicates that low achievement can conversely contribute to problem behavior and that low…
