This study examined how adolescents' emotions in mathematics develop over time. Growth curve modeling was applied to longitudinal data collected annually from 2002 to 2006 (Grades 5-9; N = 3425 German adolescents; M[subscript age] = 11.7, 15.6 years at the first and last waves, respectively; 50.0% female). Results indicated that enjoyment and…

Discrepancies among family members' ratings on aspects of family functioning are challenging both, methodological and interpretational. Family members' perspectives and their discrepancies are indicators of family functioning, affecting adolescents' psychological development. Previous research focused on linear effects, ignoring that rather…

The following survey study uses a quantitative research design to investigate motivational and affective aspects of students (aged 14-17) in a mathematical workshop on graph theory. Motivational and affective aspects are related to heart rate measurement (using the digital medium of a pulse watch) in mathematical knowledge development processes in…

In their recently renamed theory, situated expectancy-value theory (SEVT), Eccles and Wigfield (2020) emphasized the importance of situations in influencing individuals' motivational beliefs and academic choices. Adopting a novel approach--network analysis--this study aimed to examine how situations may impact the associations among expectancies,…

We examined whether German adolescents who participated in an adapted 8-week school-based intervention, the "Identity Project," reported greater changes in heritage and global identities and perceptions of classroom cultural climate. We used a longitudinal, wait-list control design pooling eight classrooms across the school years of…

A central goal of physical education (PE) is to empower students to be physically active in a health-enhancing way. Therefore, using a competence-based approach, the objective of the health- and fitness-related PE intervention 'Promotion of physical activity-related health competence in PE' (GEKOS) was to address practical and theoretical content…

Nature conservation and environmental protection are not only visible in the media, but also play a role in the everyday life of young people, as evidenced by 'Fridays for Future', a demonstration for climate justice. To facilitate the embedding of conservation in school contexts, this study addresses the ideas and approaches which students have…

Purpose: This paper aims to propose and evaluate an innovative approach to education for sustainable consumption (ESC) which empowers teenagers and young adults to improve sustainable consumption competences. This approach combines pedagogical learning approaches such as real-world learning (e.g. experiential learning and research-based learning)…

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…

This study investigated whether a country's policy context for immigrant integration was related to native adolescents' attitudes towards ethnic minorities in European countries, using data from the International Civic and Citizenship Education Study. We found that students in a country with more inclusive and multiculturalist policies for…

Many students suffer from motivational problems when doing homework. To investigate whether an intervention that effectively promoted value beliefs in mathematics promoted students' homework motivation and behavior, we analyzed data from a cluster randomized controlled study with two classroom-based relevance interventions (writing a text or…

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…

Political education in school is aimed at preparing adolescents for their role as citizens, which comprises political participation as well as political knowledge. While it is generally agreed that basic knowledge about politics is a prerequisite to participation, the specific link between knowledge and participation is left unclear in normative…

Teen dating violence (TDV) and school violence (SV) are two major social problems in adolescence. Until recently, the antecedents of both TDV and SV have been analyzed largely independently of each other. This study analyses and compares the determinants of both TDV and SV, with a focus on physical violence. Based on a comprehensive survey of…

Biology, a living science, is known as a balance and complement among other branches of science. Just like the science of biology, biology as a course also plays a very important role among other courses at all school types and grades. It is thought that the adults of the future should not be deprived of knowledge in the field of biology and…
