The conceptual development of natural number in preschoolers is well-researched. However, less is known about the conceptual development of zero. Recent studies suggest that children develop an understanding of zero after learning to count. It remains unclear, when a conceptual understanding of "zero" as number word for an empty set…

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.

Background: Phonological difficulties are prevalent in children with speech and/or language disorders and may hamper their later language outcomes and academic achievements. These children often form a significant proportion of speech and language therapists' caseloads. There is a shortage of information on evidence-based interventions for…

"Research Findings:" Promoting children's science knowledge by adequate measures such as guided or free play is a cardinal goal of preschool. However, there is considerable variability in preschool teachers' instructional quality in block play, which might be associated with children's domain-specific science skills but also their…

Research Findings: We assessed socio-emotional behavior, nonverbal reasoning, German receptive language, and motor skills of refugee children attending early childhood development [ECD] programs and of those who did not (N = 207, mean age = 69.4 months). Young refugee children overall demonstrated lower levels of development and more…

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…

The early educational support of basic school skills during nursery can have a positive impact on a successful transition into primary school and future school success and achievement -- especially for in this context low-performing children. Therefore, most German nurseries developed additional concepts to support the acquisition of basic school…

The present study is based on longitudinal data from a German early childhood education and care (ECEC) governmental initiative assessing children's grammatical and vocabulary development between 2;6 and 4;0 years (N = 1,331), quality of the home learning environment and quality of the preschool setting. Results showed that the quality of the home…

Pretend play may be beneficial for young children's social development. However, empirical results to date are inconsistent and limited, which is partly due to a lack of psychometrically sound measures for children's social pretend play competence. The current study aimed to compare and validate different assessment methods for children's social…

This study investigates whether children's preschool experiences are associated with later achievement via enhanced learning behaviors using data from a German longitudinal study following children (N = 554) from age 3 in preschool to age 8 in second grade. There were two main findings. First, results suggest that more positive learning behaviors…

Based on longitudinal data (n = 338) from the German National Educational Panel Study (NEPS) competence development (mathematics and language) of three groups with different mathematical preconditions (+/- 1 SD) were compared between age 4 to 10. Groups were composed by first measurement of mathematical achievement in pre-school age (5/6 years).…

The general gender discourse has currently revealed gender gaps as early as at preschool age. To analyze developmental differences between boys and girls in Mecklenburg-Western Pomerania, n = 4,251 preschoolers aged 48-83 months were examined by means of the 'Dortmund Developmental Screening for Preschools 3-6' (DESK 3-6). Using the…

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…
