Many children have significant mathematical learning disabilities (MLD, or dyscalculia) despite adequate schooling. The current study hypothesizes that MLD partly results from a deficiency in the Approximate Number System (ANS) that supports nonverbal numerical representations across species and throughout development. In this study of 71 ninth graders, it is shown that students with MLD have significantly poorer ANS precision than students in all other mathematics achievement groups (low, typically, and high achieving), as measured by psychophysical assessments of ANS acuity (w) and of the mappings between ANS representations and number words (cv). This relation persists even when controlling for domain-general abilities. Furthermore, this ANS precision does not differentiate low-achieving from typically achieving students, suggesting an ANS deficit that is specific to MLD. 相似文献

This paper documents the new trend towards a first-language-first multilingual model in formal education in three former French
colonies of West Africa, namely Burkina Faso, Mali and Niger. It compares the sociolinguistic situations, the conditions of
the development of multilingual education and the achievements of mother-tongue-medium education in all three countries. The
evidence is that, contrary to common discourse in francophonie, a strong first-language-first model in formal education is the best guarantee of a good mastery of French and, more generally,
of quality education in francophone countries. 相似文献

This chapter first presents a review of research on the development of adopted children, focusing on meta‐analytic evidence and highlighting comparisons between adopted children with and without histories of early adversity. Some methodological issues arising from this literature are considered as well. Second, 7 longitudinal studies of adopted children's development are described, and the convergence of findings across the longitudinal studies and with the cross‐sectionally based meta‐analytic evidence is discussed. Third, the role of the adoptive family in supporting adopted children's development is explored. 相似文献

This paper presents some results of a qualitative study carried out in a secondary school in the city of Buenos Aires (Argentina). It examines how two students from poor families responded to, and viewed, aggression by peers at their school. This paper argues that the examination of students’ narratives about aggression (based on classism and sexism) illustrates the analytical usefulness of the moral dimension of social life to unpack crucial aspects of the micro politics of class and gender and processes of identity-making. Following Sayer, this article maps students’ responses to immoral sentiments and misrecognition: the search for respect and respectability, and moral boundary drawing. It demonstrates that these reactions are entangled in students’ class and gender identity-making. It also shows how ‘victims’ are able to regain respect. However, the individualized nature of these processes and the spirals of aggression they instigate demonstrate the fragile and temporary nature of this achievement. 相似文献

This article examines how students from the ‘loser’ sections of the middle class dealt with the game of secondary schooling in a ‘good’ state school in the city of Buenos Aires (Argentina). It engages with Bourdieu’s theory of social practice and, in particular, with its concepts of game, habitus and cultural capital. It argues that middle‐class students embody a school habitus, which I call zafar. Zafar (a Spanish slang word) refers to students’ dispositions, practices and strategies towards social and educational demands of teachers and their school. Zafar propels middle‐class students to be just ‘good enough’ students, and promote an instrumental approach to schooling and learning. Although this paper offers an account within which the reproduction of relative educational advantage of a group of middle‐class students takes place, it also poses questions about their future educational and occupational opportunities. 相似文献

A group randomized controlled trial tested the efficacy of the Friendly Schools program to reduce student bullying behaviour. This socio‐ecological intervention targeted the whole school, classroom, family, and individual students to reduce bullying behaviour. Self‐report data were collected in 29 schools over three years from a cohort of 1968 eight to nine‐year‐olds. Surveys measured frequency of being bullied, bullying others, telling if bullied and observing bullying. Results indicate that intervention students were significantly less likely to observe bullying at 12, 24 and 36 months and be bullied after 12 and 36 months, and significantly more likely to tell if bullied after 12 months than comparison students. No differences were found for self‐reported perpetration of bullying. The findings suggest whole‐of‐school programs that engage students in their different social contexts appear to reduce their experiences of being bullied and increase their likelihood of telling someone if they are bullied. 相似文献

Objective
Psychological maltreatment (PM) is the most prevalent form of child abuse, and is the core component of most of what is considered as child maltreatment. The aim of this work was to explore differential adverse outcomes of the different types of PM in the mental health and functioning of children living in homes in which they are exposed to intimate partner violence (IPV).Method
Participants were 168 children, aged between 4 and 17, whose mothers experienced IPV. They were assessed using different measures of psychopathology and functioning: Diagnostic Interview for Children and Adolescents-IV, Child Behavior Checklists and Child and Adolescent Functioning Assessment Scale. Furthermore, IPV was assessed with the Schedule for Assessment of Intimate Partner Violence Exposure in Children and the Index of Spouse Abuse. Statistical analyses were carried out with regression models adjusted by means of Generalized Estimating Equations.Results
Spurning was the PM subtype with the greatest global effect on the children, as it was significantly associated with internalizing and externalizing problems. Denying emotional responsiveness specifically increased the risk of internalizing psychopathology and impairment in the emotional area. Terrorizing was not significantly associated with a greater number of negative outcomes in children's psychopathology or functioning in this population.Implications
The results suggest the importance of taking PM types into account in order to fully understand the problems of children exposed to IPV at home, and for the design of effective treatment and prevention programs. 相似文献68.

Digital libraries of scientific articles contain collections of digital objects that are usually described by bibliographic metadata records. These records can be acquired from different sources and be represented using several metadata standards. These metadata standards may be heterogeneous in both, content and structure. All of this implies that many records may be duplicated in the repository, thus affecting the quality of services, such as searching and browsing. In this article we present an approach that identifies duplicated bibliographic metadata records in an efficient and effective way. We propose similarity functions especially designed for the digital library domain and experimentally evaluate them. Our results show that the proposed functions improve the quality of metadata deduplication up to 188% compared to four different baselines. We also show that our approach achieves statistical equivalent results when compared to a state-of-the-art method for replica identification based on genetic programming, without the burden and cost of any training process. 相似文献

Our work concerns the design of robust information retrieval environments that can successfully handle queries containing misspelled words. Our aim is to perform a comparative analysis of the efficacy of two possible strategies that can be adopted. 相似文献
