Academic self-concept (ASC) is characterized by the dual nature of stability and change. That is, students strive for consistency in their self-concept but also receive achievement feedback that leads to changes in ASC. Only a few previous studies have scrutinized the stability of ASC. The STARTS model (Stable, AutoRegressive Trait, and State)…

Demonstrating the differential effectiveness of instructional approaches for learners is difficult because learners differ on multiple dimensions. The present study tests a person-centered approach to investigating differential effectiveness, in this case of reading instruction. In N = 517 German third-grade students, latent profile analysis…

Children in early childhood education and care (ECEC) spend a considerable amount of time interacting with their peers. However, open questions remain on whether and how children influence their peers' language development. The present study examined effects of peers' German receptive vocabulary (n = 1,871) on individual children's (n = 431)…

The objective of the study was to analyse whether young people with physical disabilities have lower global self-esteem and less positive domain-specific self-concepts than peers without physical disabilities, as well as which processes protect their self-esteem. Data were collected from 179 German adolescents with physical disabilities and 296…

With the growing popularity of early foreign language learning (EFLL) programmes in elementary schools, the transition to secondary school constitutes a crucial bridge. Ensuring a smooth transition that builds on students' L2 language proficiency and gradually shifts pedagogical approaches is key for long-term success. The present study examines…

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…

We examined independent and interactive links among three central characteristics of children's experiences in early childhood education and care and the German receptive vocabulary of single language learners and dual language learners (DLLs). We allowed for possible differential effects depending on children's language background. Our sample…

In recent years, the number of new asylum applications in Germany has risen with a peak in 2015. Many refugees arrive with high levels of prior education and corresponding educational aspirations. Hence, German universities and preparatory colleges (so-called 'Studienkollegs') have created additional preparatory courses and supporting services for…

Whereas equity issues are mainly discussed with respect to students at risk, this article focuses on mathematical potentials of under-privileged students and therefore elaborates a wide, dynamic and participatory conceptualization of (sometimes still hidden) mathematical potentials. An extended research review theoretically and empirically grounds…

Accessing higher education without having to overcome bureaucratic hurdles is a serious concern for refugees. Although empirical studies on the integration and success of refugees in higher education are scarce, the challenges related to this issue are becoming apparent. The Success and Opportunities for Refugees in Higher Education (SUCCESS)…

Foreign language education has now been implemented at the elementary school level across Europe, and early foreign language education has gained traction following language policies set by the European Commission. The long-term effects of an early start, however, have not received ample scientific scrutiny. The present study assessed early…

During student development, enriching academic and psychosocial activities in accordance with different educational needs of students is important. This study aims to identify primary school teachers' opinions in Turkey, Czech Republic, Italy, and Germany. The opinions of teachers were investigated and compared on the individual skills, interests,…

This study investigated how student characteristics predict the nature of girls' and boys' verbal interactions with their teachers in physics classes. The sample included (N = 1378) students from 81 randomly selected high-school physics classrooms in Germany and the German-speaking part of Switzerland. At the beginning of the school year, the…

TIMSS (Trends in International Mathematics and Science Study) is an international assessment of mathematics and science at the fourth and eighth grades that has been conducted every four years since 1995, with the most recent assessment in 2011. PIRLS (Progress in International Reading Literacy Study) is an international assessment of reading…

Prior research has demonstrated that teachers' professional knowledge and motivation are strongly related to students' learning and motivation. Symptoms of teachers' stress and burnout (e.g., emotional exhaustion) are also thought to influence students' achievement, but no empirical study has tested this prediction. Using multilevel analyses and a…
