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…

Research on the big-fish-little-pond effect demonstrates that class-average achievement negatively affects students' academic self-concept via social comparison processes. The neighborhood-effects literature reports positive effects of advantageous socioeconomic neighborhood conditions on students' academic development via collective socialization…

Young students who speak a different language at home than that spoken in school (i.e., a minority home-language) appear to exhibit a biased reading self-concept. Importantly, this biased reading self-concept may correspond with altered causal pathways between reading self-concept and achievement in minority home-language students. To test this…

The relation between nonword repetition and vocabulary has been the focus of a theoretical controversy for several decades. The point of contention is whether the ability underlying nonword repetition drives vocabulary growth or vice versa. The present study examines longitudinal interrelations between nonword repetition and vocabulary from age 3…

In this study, we examine the knowledge of students in a master program in business and economics and explore whether migration-specific influences can be determined. We tested the knowledge of 1,451 students from 40 universities in Germany in the content areas of accounting, finance, and microeconomics. Migration background had a significant…

In times of climate change, worldwide diseases, and the question of sustainable energy, scientific literacy has never been more important. The acquisition of scientific literacy starts in early childhood and depends on children's experiences in learning environments such as the parental home and kindergarten. The Starting Cohort 2 of the German…

Research Findings: Are family literacy activities linked to gains in preschool-aged dual language learners' (DLLs') societal language vocabulary? To understand connections between literacy activities and vocabulary, we separately considered literacy activities in the respective heritage language and in the societal language, German, and accounted…

This article examines factors that promote active multilingualism. For this purpose, the "Peabody Picture Vocabulary Test" was used with 48 children. Their results were linked to a parental questionnaire designed to evaluate the children's linguistic input in their immediate environment. The study shows that, besides a minimum amount of…

Lexical development of bilingual children is influenced by a number of input factors. In the present study, early lexical skills of 25-month old children growing up with Turkish and German were assessed. Parents of 92 children filled out a newly developed list for productive Turkish vocabulary, as well as a vocabulary list for German. A parental…

Several studies have revealed the cognitive and linguistic benefits of balanced bilingualism, but the research on balanced biliteracy is still in its initial stages (Marinis et al. submitted. "Biliteracy Education Impacts on Cognition Selectively"). This study investigates the positive effects of balanced biliteracy on the development of…

This paper focuses on the influence of socio-economic risk factors and different aspects of the home learning environment in early childhood on children's language competencies (vocabulary and grammar skills). The assumption is that children with more risk factors have lower competencies, but the home learning environment (measured by everyday…

Academic language has been shown to significantly contribute to success across school subjects. However, to date, there are no empirical studies addressing its development across primary school age. The present study investigated the growth of academic vocabulary and influential conditions from Grades 2 to 4 based on a newly developed and…

Background: Although various studies on general language performance have investigated determinants of students' reading comprehension (e.g., reading amount), they have paid insufficient attention to how students perceive parental values influence their language-related values and behaviour--and, as a consequence, their performance. This is…

This study investigates social and ethnic differences in the use of early childhood education and care (ECEC) centers with different learning environments in an ECEC system with universal state-subsidized provision and low fees. Based on the German National Educational Panel Study-Kindergarten Cohort from 2011, we matched data on 587 groups in 253…

Children develop linguistic competencies during interactions with more knowledgeable others. Consequently, one way to support this development is by enhancing the home literacy environment (HLE) in which children live. In this study a non-intensive intervention procedure was developed to improve HLE and linguistic competencies of 125 German…
