Previous research has shown that early numerical abilities are predictive of later mathematical achievement. In line with these previous studies, we investigated whether early numerical abilities are also associated with later probabilistic reasoning abilities. In the present study, we examined children's numerical abilities in the second grade of…

The many studies with coin-tossing tasks in literature show that the concept of randomness is challenging for adults as well as children. Systematic errors observed in coin-tossing tasks are often related to the representativeness heuristic, which refers to a mental shortcut that is used to judge randomness by evaluating how well a set of random…

Findings on children's proportional reasoning abilities strongly vary across studies. This might be due to the different contexts that can be used in proportional problems: fair-sharing, mixtures, and probability. A review of the scientific literature suggests that the context of proportional problems may not only impact the difficulty of the…

The present study investigates the effects of teachers (background qualifications, attitudes and beliefs, and instructional practices) on student achievement in mathematics, reading, and spelling in 1st grade. Its theoretical framework and methodology are based on recent work by Palardy and Rumberger (2008). Data from the SiBO Project, a…

Academic emphasis, collective efficacy, and faculty trust in students and parents (3 school characteristics positively associated with student achievement) are assumed to form a higher order latent construct, "academic optimism" (Hoy, Tarter, & Woolfolk Hoy, 2006a, 2006b). The aim of the present study is to corroborate the latent…

The role of children's on-task behavior in the prevention of aggressive behavior was assessed among 570 Dutch speaking children followed from second- to third-grade elementary school in Flanders, Belgium. A first objective was to investigate whether individual level variation of on-task behavior moderated the impact of a universal preventive…

This study examined whether teacher-child interactions characterized by teacher involvement, structure, and autonomy support at the beginning of second grade predicted children's global, academic, social, and behavioural self-concept at the end of second grade. The study was conducted in 30 second grade classrooms with 570 children and their…

This study aimed to understand how relationships with peers and teachers contribute to the development of internalizing problems via children's social self-concept. The sample included 570 children aged 7 years 5 months (SD = 4.6 months). Peer nominations of peer rejection, child-reported social self-concept, and teacher-reported…

The links between children's externalizing behaviors and two characteristics of children's social interactions within the classroom, namely, peer social preference and received support from the teacher, were studied in 570 children followed from their 2nd- to 3rd-grade years of elementary school. Data consisted of peer and teacher reports of…

The role of teacher behavior management for children's disruptive behavior development (hyperactive and oppositional behavior) was investigated using a universal classroom preventive intervention study. Five-hundred seventy children were followed from second to third grade of elementary school. Observations of teacher behavior management and…

A considerable body of previous research has demonstrated that differences between schools and classes have an impact on students' learning and acquisition of skills. It is not yet clear, however, whether the effects persist in the longer term. The present study examines the effect of primary schools and classes on language and mathematics…

This study addresses the effects of secondary schools and classes on language achievement in Flanders, Belgium. The results of a three-level analysis (students within classes within schools) indicate that the group composition at the class level is very important. In classes with a high average initial cognitive ability or a large proportion of…
