This longitudinal cross-lagged panel study investigated the development of the structure of young children's spontaneous number focusing tendencies and their longitudinal associations with numerical abilities and mathematics achievement over the course of a 3-year period, that is, in the second and third year of kindergarten and in first grade of…

The current study presents a review of intervention studies conducted in the Low Countries (i.e., The Netherlands and Flanders) focusing on social-emotional behaviors in the school. The primary purpose of this review was to assess whether studies included an operational definition of the intervention under study and reported data on the…

People often have difficulties in understanding situations that involve non-linear processes. Also, the topic of non-linear functions is introduced relatively late in the curriculum. Previous research has nevertheless shown that already children aged 6 years and older are able to discriminate non-linear from linear processes. Within the present…

Despite numerous studies, the link between verbal working memory (WM) and calculation abilities remains poorly understood. The present longitudinal study focuses specifically on the role of serial order retention capacities, based on recent findings suggesting a link between ordinal processing in verbal WM and numerical processing tasks. Children…

The current study examines the impact of alternative education on children's early school engagement in terms of school enjoyment and independent participation. A sample of 2,776 children from traditional (e.g., mainstream) and alternative (Freinet and Waldorf) Flemish schools was followed from their 3rd year of kindergarten until 3rd grade. The…

This longitudinal study evaluated the impact of dyadic and classroom-level teacher-child relationship quality in first grade on children's psychosocial and academic adjustment in first (N = 3,784), second (N = 3,666), and third (N = 3,582) grade, controlling for several child features, namely, child demographics and children's initial levels of…

In a 3-year longitudinal study, 471 children were classified, based on their performances on arithmetic tests in first and second grade, as having persistent arithmetic disabilities (AD), persistent low achieving (LA), persistent typical achieving, inconsistent arithmetic disabilities (DF1), or inconsistent low achieving in arithmetic. Significant…

Arithmetic abilities acquired in kindergarten are found to be strong predictors for later deficient arithmetic abilities. This longitudinal study (N = 684) was designed to examine if it was possible to predict the level of children's arithmetic abilities in first and second grade from their performance on preparatory arithmetic abilities in…
