The present study tests two predictions stemming from the hypothesis that a source of difficulty with rational numbers is interference from whole number magnitude knowledge. First, inhibitory control should be an independent predictor of fraction understanding, even after controlling for working memory. Second, if the source of interference is…

This study aims to establish a Turkish version of the Children's Inventory of Anger Scale (ChIA) developed by Nelson and Finch (2000) to evaluate the intensity of anger experienced in potentially anger-provoking situations in children. The research sample consists of 502 primary and secondary school students attending their education in Hatay…

Background: Children with developmental coordination disorder (DCD) frequently have difficulties performing gross motor skills such as the overarm throw. Our study examines the differences in both qualitative and quantitative characteristics of overarm throwing for accuracy between typically developing (TD) and children with DCD. Methods: A total…

This research investigates the prediction of delaying gratification on game addiction among primary school students who attend the 3rd and 4th-grade. This study, in which the delay of gratification behaviour correlated with game addiction among children, was carried out using a descriptive survey model. The study sample consisted of 318 students…

The current research used longitudinal data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (N = 1,103) to examine the developmental autoregressive cascades of prosocial behavior, academic competence, and peer exclusion in Grades 3-6. The cascade paths revealed that Grade 3…

The goal of this study was to examine the unique associations of aggression with peer status in a non-Western context. The moderating effects of peer community and teacher closeness at the classroom level and gender and grade at the individual level were considered. Participants were 1954 third to sixth grade students (M[subscript age] = 9.60…

The present longitudinal study examined how and why classroom-level victimization moderates the prospective association between peer victimization and depressive symptoms with 2,643 third- and fourth-graders (M[subscript age] = 10.01 years) in China. Multilevel modeling revealed that peer victimization was more strongly associated with increasing…

The purpose of this study was to evaluate the influences of a structured after-school program on student physical activity for third- through fifth-grade students at five schools in southern Colorado. The study utilized a pretest-posttest intervention design in which six elementary schools in a low socioeconomic status school district in southern…

Martin Wagenschein's ideas of prioritising phenomena in making sense of science processes have influenced the German "Lehrkunstdidaktik" (art of teaching) approach. This article sketches a "Lehrkunstdidaktik" teaching unit inspired by Michael Faraday's "Chemical History of a Candle." It shows how primary and lower…
