This study investigated the objectivity, reliability, and the validity of the Basketball Throw Test (BTT) as an upper-body muscular strength measure. Participants (33 boys and 32 girls; mean age = 8.75 ± 1.47) performed the BTT on 2 occasions (1-week apart), and the hand-grip test as criterion measure. The objectivity and reliability were…

Research has established that reading and writing skills are closely linked for most individuals, which can be explained by the shared knowledge and functional relations theoretical perspectives. The current study used quantile regression to explore differences between and within Grades 3-5 in the United States in the associations between a…

Personal values are broad motivational goals that have been found to have systematic relations with subjective wellbeing in adults. Values that promote higher subjective wellbeing are considered "healthy" while those that hamper it are considered "unhealthy" (Schwartz & Sortheix, 2018). However, little is known about these…

We studied the effect of the number and characteristics of siblings (sex, age) on school achievement in several grades (kindergarten, first grade, and fifth grade), in two large French cohorts, with more than 16,000 children. Running linear mixed-effects models, we find that, independently of socioeconomic status, having more siblings is…

Purpose: Syntax provides critical support for both academic success and linguistic growth, yet it has not been a focus of language research in school-age African American children. This study examines complex syntax performance of African American children in second through fifth grades. Method: The current study explores the syntactic…

Early algebraic thinking is the reasoning engaged in by 5- to 12-year-olds as they build meaning for the objects and ways of thinking to be encountered within the later study of secondary school algebra. Ever since the 1990s when interest in developing algebraic thinking in the earlier grades began to emerge, there has been a steady growth in the…

Purpose: Good verbal signals and low background noise are key factors for all children to maximize understanding of what is being taught. Classroom shape, surroundings, and even furnishings change how the environment "sounds" and how speech is "heard" in the classroom. Classroom acoustics is perhaps one of the most important,…

Evidence for associations between spatial skills and mathematics has led to the argument that spatial visualization plays a role in mathematical calculation. However, there is no single accepted definition of what spatial visualization encompasses. Here, we investigated spatial visualization in the context of a mental imagery framework. We applied…

Over the past six decades, the field of teaching modern foreign languages to young learners has come a long way, from the early surmises about the advantages of a young start to today's widespread integration of foreign languages into curricula in public and private schools. The chapters in this book bring together internationally renowned…

Reading disability (RD) may be characterized by reduced print-speech convergence, which is the extent to which neurocognitive processes for reading and hearing words overlap. We examined how print-speech convergence changes from children (mean age: 11.07±0.48) to adults (mean age: 21.33±1.80) in 86 readers with or without RD. The participants were…

This study investigates the effect of programming courses on the computational thinking (CT) skills of elementary school students and the learning effectiveness of students from different backgrounds who are studying programming. We designed a OwlSpace programming course into an elementary school curriculum. Students in fourth and fifth grades…

The main aim of this study was to investigate a conceptual model linking subtypes of social withdrawal, social/asocial dissatisfaction, and internalizing problems in late childhood and early adolescence. Participants were N = 459 students (n = 247 girls) aged 8-14 years (M = 11.24, SD = 1.66), who completed self-reports assessments of social…

Recent studies established that making concurrent judgments of learning (JOLs) can significantly alter (typically enhance) memory itself--a "reactivity" effect. The current study recruited 190 Chinese children (M[subscript age] = 8.68 years; 101 female) in 2020 and 2021 to explore the reactivity effect on children's learning, its…

Evaluative conditioning (EC) refers to a change in liking of a conditioned stimulus (CS) consecutive to its repeated pairing with a valent unconditioned stimulus (US). We relied on a multinomial processing tree model to compare the processes underlying EC in middle-aged children (n = 57, M[subscript age] = 8.65, range = 6.94-11.03; 31 females) and…

Anxious and depressive symptoms are highly prevalent in school-aged youth and can lead to a multitude of negative outcomes. School-based mindfulness interventions may be able to target gaps in evidence-based treatments for anxious and depressive symptoms. The current meta-analysis aimed to synthesize the literature of school-based mindfulness…
