We investigated the effect of cognitive training of executive functions on children's cognitive outcomes. To address this issue, a systematic meta-analysis of published research articles on cognitive training interventions was performed considering children's age, training duration, -procedure, and -technology in moderator analyses. The results (N…

Over half of the children in the U.S. experience adversity early in childhood. These experiences, along with conditions in their families and neighborhoods, have profound developmental effects. The bioecological model of development includes these proximal contexts in a theory of development that incorporates the threats and supports present in…

This study describes changes in cognitive persistence, a key measure of mastery motivation, between the ages of 10 (grade 4) and 14 (grade 8). Prior research in the field of mastery motivation has focused mainly on early childhood. No longitudinal research findings have been published about age changes in mastery motivation during the school…

One possible way of evaluating set curricula is to examine the consistency of study programmes with students' psycho-cognitive development. Three theories were used to evaluate matching between developmental theories and content proposed in the mathematics programmes (geometry section) for primary and the beginning of secondary education. These…

In a rural Alabama school district, 38.46% of the students failed the reading portion of the high school graduation examination. While the teachers in the school district were trained to differentiate instruction according to ability and gender, the impact of gender-differentiated reading instruction was unknown. The purpose of this case study was…

When do children develop the ability to imagine their future lives in terms of a coherent prospective life story? We investigated whether this ability develops in parallel with the ability to construct a life story for the past and narratives about single autobiographical events in the past and future. Four groups of school children aged 9 to 15…

Dual-process theories have been proposed to explain normative and heuristic responses to reasoning and decision-making problems. Standard unitary and dual-process theories predict that normative responses should increase with age. However, research has focused recently on exceptions to this standard pattern, including developmental increases in…

Science educators have long been concerned with how formal schooling contributes to learners' capacities to engage with science after school. This article frames productive engagement as fundamentally about the coordination of claims with evidence, but such coordination requires a number of reasoning capabilities to evaluate the strength of…

According to Klahr's (2000, 2005; Klahr & Dunbar, 1988) Scientific Discovery as Dual Search model, inquiry processes require three cognitive components: hypothesis generation, experimentation, and evidence evaluation. The aim of the present study was to investigate (a) when the ability to evaluate perfect covariation, imperfect covariation,…

In this study, we identified unique clusters of parenting behaviors based on parents' school involvement, community involvement, rule-setting, and cognitive stimulation with data from the Panel Study of Income Dynamics-Child Development Supplement. In early (n = 668) and middle adolescence (n = 634), parents who provided high cognitive stimulation…

What kind of developmental potential is present in elementary schoolchildren but hindered by the traditional type of education? Half a century ago Daniel El'konin and Vasili Davydov, the leaders of Russian Vygotskian educational psychology started answering this question. They suggested that reflection is a basic human ability and it can be…

The impact of date of birth on cognitive test scores is well documented across many countries, with the youngest children in each academic year performing more poorly, on average, than the older members of their cohort (see, for example, Bedard and Dhuey (2006) or Puhani and Weber (2005)1). However, relatively little is known about the driving…
