In this dissertation I report findings from two studies of the literacy abilities of children with Williams syndrome (WS), a genetic disorder associated with intellectual disability. I had two overarching goals: 1) evaluate the applicability of theories of reading and spelling acquisition developed based on typically developing children to…

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…

The much-needed interest in promoting a healthy lifestyle among school-age students has found a context for development: school gardens. There are numerous studies where using gardens as a teaching-learning context also improves students' performance in the experimental sciences. In this study, we proposed another interest that sets it apart and…

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…

Research Findings: Greater self-regulation has been identified as a protective factor for low-income children's academic achievement. However, we know less about the long-term protective nature of specific aspects of self-regulation. Data were drawn from predominantly African American and Latino children in low-income communities in Boston,…

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…

Multiple studies have shown that children conform to majorities in perceptual judgment tasks against their better knowledge. However, these studies report contradictory results about how conformity develops over age. Here, we study variation in conformity over the course of middle childhood: we examined potential informational and normative…

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…

In this article, the author focuses on spatial research in early childhood visual art education as a way to parse out the value of spatiality in research as an "ethics of participation." There are two specific ways that spatiality is explored in this paper. First, spatiality as material provides a way to highlight one's interconnected…

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…

Curiosity is a wonder of the human mind. It goes to the heart of modernity, as a driving force for learning, novel insights, and innovation, both for individuals and communities. In societies dependent on science and development, finding out what promotes or hampers curiosity and wonder in school curricula and science education is accordingly…

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…
