The purpose of the present article was to gain knowledge about what aspects of, and in what way, contextual and conceptual intersubjectivity contribute to emergent science knowledge about sound. Starting from a Vygotskian theoretical base, the article rests on the work of Fleer (early learning and development. Cultural-historical concepts in play,…

Analysis of life narratives of 20 West Bank Palestinians who grew up during First Intifada revealed an experience of having "lost childhood'. This experience included various aspects categorized into "lost child-friendliness" and "lost childlikeness". Participants attributed their sense of lost childhood to having grown up…

A randomized control intervention study was conducted to evaluate the effects of the highly structured Heidelberg Parent-Based Language Intervention (HPLI). The outcomes of 43 children (n = 23 intervention, n = 20 control) who had been identified as late talkers during routine developmental check-ups carried out in pediatric practices at the age…

This article reports results from a study investigating the impact of a sustained, comprehensive early algebra intervention in third grade. Participants included 106 students; 39 received the early algebra intervention, and 67 received their district's regularly planned mathematics instruction. We share and discuss students' responses to a written…

Communication partners who efficiently use augmentative and alternative communication (AAC) are essential interaction partners for children learning to communicate using AAC. This systematic review examines studies targeting interventions designed to help communication partners support children with complex communication needs who use AAC.…

Research Findings: Several recent studies carried out in the United States and abroad (i.e., Asia and Europe) have demonstrated that the ability of young children to regulate their behavior (including inhibitory control, working memory, attentional control) significantly predicts their academic achievement. The current study examined the…

Background: Individuals with fragile-X syndrome exhibit developmental delay, hyperexcitation and social anxiety; they also show lack of attention and hyperactivity. Few studies have investigated whether levels of functioning change with increasing age. Here, we explored developmental changes across adolescence in the cognitive and behavioural…

Teenage mothers are more likely to use drugs, and their children are more likely to use substances and become pregnant during adolescence. Teenage mothers' substance use may play a role in the intergenerational risk for adolescent pregnancy. Pregnant adolescents (12-18 years) were seen during pregnancy and postnatal years 6, 10, 14, and 16 (n =…

As schools become living sites of evidence-based practice, teachers increasingly accumulate large quantities of observations and records. In these times of an overabundance of documentation, there is a need to find the "unit of analysis" that determines the essence of what matters for assessment. In drawing upon cultural-historical…

Existing literature shows promising effects of physical activity on children's cognitive outcomes. This study assessed via a randomized, controlled design whether additional curricular physical activity during the school day resulted in gains for children's fluid intelligence and standardized achievement outcomes. Participants were children…

Across the country, state legislatures are turning to evidence-based policymaking to ensure that taxpayer dollars are spent efficiently and effectively. One example is family support and coaching. In response to research confirming that the early years of childhood affect learning, behavior, and health for a lifetime, many states have invested in…

The understanding of the significance of movement to learning benefits from advances in neuroscience. This study considered a neurophysiological perspective in relation to the educational theory of Accelerated Learning (AL) for which little empirical evidence exists. Childhood development themes and learning strategies from a…

Use of multivariate analysis (e.g., multivariate analysis of variance) is common when normally distributed outcomes are collected in intervention research. However, when mixed responses--a set of normal and binary outcomes--are collected, standard multivariate analyses are no longer suitable. While mixed responses are often obtained in…

A Community Based Participatory Research (CBPR) framework was used in this study to gather and analyze the perceptions of mothers involved in a critical family literacy program designed to foster social and emotional development. Through narrative inquiry, participants discussed perceptions of their children's social-emotional development and the…

As young children enter formal schooling, they are at various points along their individual developmental paths toward literacy. Generally, their egocentric speech is becoming more social and they are building their capacity for logical thought and concrete problem-solving. This is a gradual development and teachers can support children's literacy…
