The number line estimation task is frequently used to measure children's numerical magnitude understanding. It is unclear whether the resulting straight, horizontal, left-to-right-oriented estimate patterns indicate task constraints or children's intuitive number--space mapping. Three- to six-year-old children (N = 72, M[subscript age] = 4.89, 56%…

The development of key linguistic abilities is essential for young children and their academic success at school, in particular for children with a migration background who are at a greater risk of developing language deficits. Here, family interactions can provide valuable opportunities to support children's linguistic learning within the Home…

Number of books at home is often associated with reading, mathematics, and science skills. Number of children's own books has rarely been considered in previous studies as a separate variable. The present study aimed to investigate relations between both of these indicators and cognitive and socio-emotional outcomes in secondary school students,…

Estimates of shared environmental influence on educational attainment (EA) using the Classical Twin Design (CTD) have been enlisted as genetically sensitive measures of unequal opportunity. However, key assumptions of the CTD appear violated for EA. In this study we compared CTD estimates of shared environmental influence on EA with estimates from…

This paper informs about a specific German concept in Pedagogy, the concept of "tact". Following an initial discussion of the particularities of the concept of (socio-) pedagogical tact, including its ethical and moral self-positioning and current demands for its operationality (1); will come the presentation of an empirical examination…

It is now 10 years since the "European Declaration on the Health of Children and Young People with Intellectual Disabilities and their Families: Better Health -- Better Lives" was adopted by the World Health Organization. Through discussions with key informants and an online literature review, we reflect on actions and progress made in…

This study explores the unique experience of disrupted sojourns and early reentry among U.S. college students who were abruptly repatriated from their study abroad experience in March 2020. Using a combination of focus groups and interviews with 25 U.S. returning students, the findings suggest that students' experiences were characterized by…

This study investigated whether various aspects of the home learning environment -- that is, learning-related processes, parental perceptions of their child, and structural characteristics -- predicted private tutoring attendance in Grade 8. We used the data of 7393 students from the German National Educational Panel Study. Seventeen percent of…

Despite the fact that third parties are present during a substantial amount of face-to-face interviews, bystander influence on respondents' response behavior is not yet fully understood. We use nine waves of the German Family Panel "pairfam" and apply fixed effects panel regression models to analyze effects of third-party presence on…

This large-scale and longitudinal study examines early home support for learning, formal/informal home mathematics activities, and their associations with children's mathematical development between age two and six. Data were collected in Germany between 2012 and 2018, N = 1184 (49% girls, 51% boys), and 15% of children had parents with a…

The successful acquisition of a heritage language (HL) has been the focus of much of the research on early bi-, tri- and multilingualism in the last years, since it is this language which is generally delimited within the family environment and finds less continuity outside this context once the multilingual child starts socialising in the…

The United States and Germany are two predominantly monolingual countries with a significant number of multilingual speakers. Previous research on multilingualism in children on the autism spectrum has found no adverse effects on children's language and communication development but often excluded children with complex communication needs or…

The present study investigates the incremental validity of the traditional books-at-home measure and selected extensions (i.e., number of children's books and number of ebooks) for explaining students' academic achievement as measured by their academic language comprehension. Using multiple linear regressions, we additionally explore the role of…

This paper presents findings from a pre-post study on pre-service teachers' beliefs about multilingualism and language use. A full cohort of pre-service middle school teachers in Germany (n = 259) was surveyed before and after completing a compulsory module on multilingualism using a validated instrument that captures participants' beliefs about…

This study analyses practices regarding home languages in a nursery school from a multilingual district in Germany, and the language policies and discourses that become visible in these. First, the context is outlined of Early Childhood Education and Care for multilingual children in Germany; then, the concepts of practices, discourses and…
