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…

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…

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…

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…

Academic achievement and academic self-concepts are reciprocally related; hence, investigating academic self-concepts should offer a potential approach for gaining a better understanding of immigrant students' (lack of) school success. Proposing that immigrant students' acculturation orientations need to be taken into account, in this study, we…

The aim of the current study was to investigate the relationship between adolescents' social support, their internalising and externalising behaviour problems, and their alcohol consumption. Adolescents attending Grade 7-10 (N = 329), answered questionnaires regarding their perceived social support (from parents, teachers, classmates, and…

Although same-sex marriages are legally recognized in many Western societies, prejudices against gay men and lesbians remain and already appear in adolescents. Since a negative attitude toward gay men and lesbians is likely to foster malevolent behaviors, we investigated predictors of homonegativity in adolescents aged between 14 and 16 years.…

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…

The aim of the current study was to investigate whether the association between parental attachment and externalizing behavior is parallelly mediated by dysfunctional emotion regulation and callous-unemotional traits. The community sample included 296 adolescents (M[subscript age]?=?14.90, SD[subscript age]?=?1.31), who completed the Inventory of…

Participation in science is unevenly distributed among secondary school students, depending on gender, social class, and ethnicity. In the present study, the influence of the home environment on students' chemistry self-concept is investigated as a factor for explaining participation in science. For this, the sociological lens of chemistry capital…

Many studies have shown a decrease in scientific interest with an increase in age. Since interest is linked to a high degree of deep-level learning, it is of great relevance to foster interest in science. This study investigates interest in biology from 7th, 9th, and 12th grade students in Germany (N=257). Results show a significantly lower…

Adolescents often do not consider sustainability in their consumption behaviours. Sustainability issues are challenging to communicate through course content alone. Against this background, the concept of fashion libraries (FLs) was introduced to adolescents at a non-denominational school in a small German city. The purpose was to explore whether…
