ABSTRACT— This article examines the role of working memory, attention shifting, and inhibitory control executive cognitive functions in the development of mathematics knowledge and ability in children. It suggests that an examination of the executive cognitive demand of mathematical thinking can complement procedural and conceptual knowledge-based approaches to understanding the ways in which children become proficient in mathematics. Task analysis indicates that executive cognitive functions likely operate in concert with procedural and conceptual knowledge and in some instances might act as a unique influence on mathematics problem-solving ability. It is concluded that consideration of the executive cognitive demand of mathematics can contribute to research on best practices in mathematics education.  相似文献

The present study examined the relationship of child maltreatment to both emotion dysregulation and subsequent eating pathology. In an effort to extend previous research, the authors examined the unique impact of childhood emotional abuse (CEA) on emotion dysregulation and eating disorder (ED) symptoms while controlling for the effects of sexual and physical abuse. Structural equation modeling was utilized to simultaneously examine the effects of all three abuse types on multiple dependent variables as well as examine whether deficits in emotion regulation mediated the relationship between abuse and eating pathology. Results from a survey of 1,254 female college students revealed significant paths from abuse subtypes to specific eating disorder symptoms, with CEA evidencing the strongest association with ED symptoms. Additionally, emotion dysregulation was positively associated with ED symptoms, and mediated the effects of emotional abuse on symptoms. Findings support previous research on the enduring effects of emotional abuse as well as highlight the importance of the assessment of CEA in the treatment of ED symptoms.  相似文献

The environmental picture book Barbapapa’s Ark was published in 1974. I was keeping a parent-observer record of my two children at the time. The book had a strong influence on them from ages three to six, moving them to query pollution and hunting, in book and environment, and as adults, becoming committed activists for the environment. Young children are routinely underestimated. Learning about the environment and conservation can begin well before formal education.  相似文献

Abstract

This article reports on the findings of an investigation in which 30 secondary schools rated the priority being given to and the likely impact on teaching and learning of a selection of 23 issues currently on the agenda for school improvement. Results are considered for the whole sample, and according to the role of respondents and school context. Schools are giving high priority to the implementation of national policies and school‐generated initiatives directed at improved classroom practice. However, the perceived impact of externally generated change is less than that of change for which school staff feel a sense of ownership. Policies directed at a consideration of resource issues, professional development and salary changes are accorded low priority and are not considered to have a marked impact on teaching and learning. There is a potential for frustration and loss of morale when policies that are thought to be of limited value within schools require time and sometimes extensive consideration. The article's conclusions for policy‐makers are directed at minimising this risk.  相似文献

Alcohol use during pregnancy poses a significant risk of fetal alcohol syndrome. This study presents the interpretive findings of the formative research phase of a funded grant to develop a community‐based public health media campaign on the topic of drinking during pregnancy. In the initial wave of data collection, 50 rural women were recruited from four Women, Infants, and Children (WIC) clinics in southeastern Iowa to participate in semi‐structured interviews. In the second wave, 10 additional WIC clients were interviewed for member‐checking purposes. Findings revealed two competing discourses that organized these women's attitudes, beliefs, and behaviors surrounding drinking and pregnancy: the discourse of individualism and the discourse of responsible motherhood. These two discourses offer opposing normative guidelines for talk among their close female relatives and friends. The implications of these findings for designing a community‐based media campaign are discussed.  相似文献

Grant regulations under the Education Minutes of 1846 prohibited ministers of religion teaching in aided schools. This article examines the background to this professional disability, the extent of its application and its survival for 112 years. The impact of changing social conditions and the creation of new justifications as the policy became anachronistic are discussed. The fiftieth anniversary of its abolition in 1959 allows a long view of this regulation, unjust yet remarkably resistant to change. Documentary sources, public and personal, reveal the actions of policy‐makers and concerns of groups and individuals, and expose complex issues forming the historical context of this contested aspect of teacher employment. Attention is given to the effects of central policy on individual schools and teachers at significant stages in the account. Finally, suggestions are made for further research on the employment of ordained teachers since the ban was lifted 50 years ago.  相似文献
