The German school system employs centrally organized performance assessments (some of which are called "VERA") as a way of promoting lesson development. In recent years, several German federal states introduced a computer-based performance testing system which will replace the paper-pencil testing system in the future. Scores from…

Private supplementary tutoring is a widespread phenomenon. However, evidence that private tutoring has positive effects on academic achievement or about the specific conditions of successful private tutoring is rare. Adapting Carroll's (1963) model for school learning to private tutoring, we expected to find positive effects of tutoring duration,…

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,…

Fostering adolescents' self-efficacy and positive emotions through learning contexts which induce beneficial achievement goals can prevent motivational decline in adolescents. Achievement goal theory states that the learning context and gender moderate the interplay of self-efficacy, emotions, and achievement goals. This study compared female and…

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…

It is well-documented that academic achievement is associated with students' self-perceptions of their academic abilities, that is, their academic self-concepts. However, low-achieving students may apply self-protective strategies to maintain a favorable academic self-concept when evaluating their academic abilities. Consequently, the relation…

Principals (policy makers) have debated the progress in U.S. student performance for a half century or more. Informing these conversations, survey agents have administered seven million psychometrically linked tests in math and reading in 160 waves to national probability samples of selected cohorts born between 1954 and 2007. This study is the…

Students' intelligence and self-concept of ability are critical predictors of school achievement. However, studies focusing on the relative importance of both achievement predictors have produced mixed results. To clarify these inconsistencies, the present study investigated whether the relative predictive power of students' intelligence and…

In science, graphs are used to visualise data, relationships and scientific principles. Basic graph reading operations, i.e. reading single data points, recognising trends as well as conducting small extrapolations from the data are important skills for pupils and lay the groundwork for a comprehensive understanding of data visualisations across…

Background: Complexity models have provided a suitable framework in various domains to assess students' educational achievement. Complexity is often used as the analytical focus when regarding learning outcomes, i.e. when analyzing written tests or problem-centered interviews. Numerous studies reveal negative correlations between the complexity of…

This study examined personality similarity between teachers and their students and its impact on teacher judgement of student achievement in the domains of reading comprehension and mathematics. Personality similarity was quantified through intraclass correlations between personality characteristics of 409 dyads of German teachers and their…

Despite its increasing popularity and adoption across Europe, Content and Language Integrated Learning (CLIL) is not without its critics. It has been argued that CLIL programmes are highly selective, that is, the students possess more favourable learning prerequisites than their monolingually taught peers. The present study contributes to this…

Considering the essential role that socio-motivational relationships at school play with respect to achievement motivation, this study examined the differences between students with a low school self-concept and students with a high school self-concept in a large sample of 7th and 8th grade students (N= 1088; M[subscript Age]= 13.7) in secondary…

Currently, many societies are placing a greater onus on academic achievement--resulting in higher levels of stress being observed among adolescent students. Stress can have detrimental repercussions on adolescents' health and is also associated with anxiety and depression. However, since less is known about how high stress levels affect school…

Coping research has consistently shown that accommodative coping is positively correlated with individuals' health. Until now, however, there have been little to no studies on the prognostic impact of accommodative coping on health, and only a few studies investigating its buffering effect on the relation between stress and health in childhood and…
