Mathematical competence in school-related contexts is a multidimensional construct that encompasses several content areas and cognitive components. Kindergarten children have experiences with different types of mathematical content. However, empirical research has focused mostly on children's numerical skills, and less is known about their…

The objective of the current study was to identify an effective learning environment for kindergarten students as they acquire an initial understanding of scientific inquiry activities (SIA) and a simple (idealized) scientific inquiry cycle (SIC). The study aimed to examine (a) the effects of instructional support and (b) the role of similarity…

Evolution is the integrative framework of the life sciences. Even though the topic is often not formally introduced before high school, young children already have various ideas about evolutionary principles (variation, inheritance, and selection) and their underlying key concepts (e.g., differential fitness, reproduction, and speciation).…

The usage of high-quality learning applications (apps) at home may increase children's mathematical and literacy competencies. This approach was tested in a family intervention study. Intervention families (n = 302) in two German cohorts (N = 500; M (SD)[subscript age] = 61.0 (4.6) months; n[female gender symbol] = 302) received tablets with newly…

Early childhood education [ECE] can foster the social-emotional adjustment and development of young refugee children. Still, the large numbers of newly arriving refugee families challenge the ECE capacities of host countries. In Germany, state authorities have subsidized flexible ECE programs for refugee children in response to this situation. The…

This 6-wave longitudinal study (2014-2018) of 161 German 5- to 10-year-olds from a midsized city and rural area in southern Germany (89 females, 72 males; predominantly White; mostly middle class) found that scientific-reasoning abilities first develop at 6 years. Abilities were highly stable, with the kindergarten score predicting 25% of…

Initiating conversations and responding to initiations of others via gestural and verbal means are prerequisites for participating in Early Childhood Education and Care (ECEC) interactions. However, research to date has not addressed the multimodal initiations and responses of young second language learners (SLLs) in natural ECEC settings. This…

Parents play a vital role in identifying children's needs for support and Early Childhood Education and Care (ECEC) features that support children's well-being. This study examined parental perspectives on features of ECEC that foster young children's well-being under and above the age of 3 years by interviewing 359 parents across nine European…

In Germany, there is still a great need for research on the quality of teacher-child interactions in ECEC institutions. Especially, because social interactions and relationships are crucial for (early) learning and development (Ulferts et al., 2019). However, there are hardly any results on factors influencing the interaction quality. This paper…

How does teacher-child interaction quality in early child care and education settings influence the development of social-emotional skills in children at around two to three years of age? We measured the quality of interactions on the side of the child care teachers (N = 9, CLASS Toddler) and assessed self-regulatory skills through an individual…

Children's early numerical competencies are of great importance for later academic achievement. Young children gain these competencies in the context of the home numeracy environment (HNE). Additionally, child characteristics and families' socioeconomic status (SES) are associated with children's competencies. In this study, we investigated…

Valid information on early social-emotional competence is essential to diagnose, treat, and prevent behavioral problems in children and adolescents. Particularly in young children, social-emotional competence is frequently measured using parent and teacher ratings that frequently exhibit low agreement. Therefore, the present study on n = 532…

The Home Learning Environment (HLE) focuses on everyday learning habits in families to support the development of children's early cognitive competencies. A growing number of studies have assessed the HLE by using different conceptual approaches and various assessment methods, often focusing on either the home literacy environment or the home…

Research Findings: The study examined the development of children's social-emotional problems between 2019 (T1) and winter 2021/22 (T2) during the COVID-19 pandemic, as well as the role of children's home and preschool learning environments. The sample included 228 German children ages 3-7 years at T1 (M[subscript Age] = 5.13, SD = 0.79, 46%…

Introducing kindergarten children to the engineering design process (EDP) is an important objective of early STEM education. Studies indicate that children often miss the crucial steps of testing and optimising during the EDP and do not persist in making solutions better. The present study explores how children's goal awareness, self-evaluation…
