The purpose of the present pilot study was to evaluate the effects of particular educational math games in kindergarten on numerical skills in Grade 1. Our participants were 49 children with early math difficulties, 65 average achievers, and 48 high-achieving 5-year-old children. All of them played various adaptive math games for 5 weeks. To avoid…

Counting abilities have been described as determinative precursors for a good development of later mathematical abilities. However, an important part of variance in mathematical achievement has also been associated with differences between instruction methods given in schools. In this study counting and instruction as predictors for mathematical…

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…

When a child does not seem to be ready for primary school, a popular practice is to grant the child more time by letting it repeat kindergarten. However, previous quasi-experimental research demonstrated negative, though diminishing, effects of kindergarten retention on academic learning during the first years of primary school. The present study…

Summer learning studies have been set up to investigate the evolution of initial group differences in academic achievement, for example, between low- and high-socioeconomic status (SES) children. Moreover, this approach has been used to demonstrate the absolute effect of going to school on children's learning. In the present study, we used…
