Many theories of giftedness either explicitly or implicitly acknowledge the role of genetic influences; yet, empirical work has not been able to establish the impact that genes have specifically on gifted behavior. In contrast, a great deal of research has been targeted at understanding the etiology of individual differences in general and specific cognitive abilities across the entire range of ability and to a lesser extent, high cognitive ability. This paper attempts to outline what we know and what we don't know about the etiology of giftedness as operationally defined as high g. We review studies selected to represent a variety of approaches that each address a different question about genetics and giftedness. These studies include quantitative genetic research which estimate heritability, shared and nonshared family environment – at the high and low ends of intelligence – as well as the heritability of group differences for general cognitive ability and specific cognitive abilities. We discuss the molecular genetic methods and mechanisms contributing to cognitive ability and suggest how epigenetic factors may operate. Quantitative and molecular genetic studies that include endophenotypes representing intelligence at a level closer to the genotype, are also included. This last group of studies represent a relatively new area of work that builds on and extends the extensive groundwork established by classic quantitative genetic studies of behavior.  相似文献

This study explores how university students representing diverse disciplines and gender differ in their self‐regulation in learning. The definition of self‐regulated learning (SRL) in the present study is based on Pintrich’s and Zimmerman’s theories of SRL and comprises motivational and learning strategies. The sample consisted of 1248 undergraduate students at several Finnish universities. The data were retrieved from the IQ Learn online self‐assessment and tutoring system. Female students scored moderately higher than male students on help‐seeking strategies, utility value and on performance anxiety. Among the diverse disciplines, minor mean differences emerged on all the sub‐dimensions of SRL, though no clear regularity on any discipline’s favour was perceived. However, male and female students of behavioural sciences and female students of sciences scored highest consistently, and the technology students, especially the male students, scored lowest. In the future, the relations between the students’ self‐regulation in learning and instructional approach should be studied further.  相似文献

Educational theorists frequently invoke rights claims to express their views about educational justice and authority. But the unyielding nature of rights claims presents a significant quandary in democratic contexts, given the tension between rights claims and majoritarian democracy. Educational theorists have given limited attention to this tension, while political theorists tend to sideline education in their analyses. In this essay Anne Newman addresses this gap by advancing a democratic rationale for educational rights. Newman's purpose is to provide a framework for advancing educational rights that protects these rights from the whims of majoritarian politics. Her central argument is that the importance of educational rights warrants giving democratic bodies far less deference than they are typically accorded. Yet the assertion of a right to a quality education, Newman emphasizes, should not be viewed as an undue constraint on democratic authority but rather is consistent with and required by the values that underlie democracy.  相似文献

The aim of the study is to compare gender patterns of student attitudes toward school, teachers and peers in grade 6 over time. In 1967–68 and in 2003, 1500 pupils responded to the same 40‐item questionnaire. A confirmatory factor analysis was applied. In the gender comparison the within‐class level was used. The more traditional school factors, Interest in School, View of Teacher, and Work Atmosphere, showed no differences between the two time periods. The factor Interest in School showed that girls were more positive than boys. In contrast to this, changes with more positive attitudes had occurred especially in boys’ peer relational factors. In Relations with Classmates and in View of Fuss, the scores were now equal between the two genders, but in View of Peers, and Lack of Anxiety the boys’ attitudinal scores were significantly higher than those of the girls.  相似文献

This article employs a transnational feminist lens to examine the experiences of racialised immigrant girls who provide care for their younger siblings. The article draws on findings from a participatory action research study in Victoria, British Columbia, Canada to examine the role that immigrant girls’ caregiving practices play in transnational families’ social, economic, and cultural survival. It argues that greater attention should be given to the diverse and complex contexts, consequences, costs, and contributions of immigrant girls’ caregiving labour.  相似文献

The aim of this study is to investigate how a community of practice focused on becoming a teacher of secondary school mathematics emerged during a pre-service teacher education programme and was sustained after students graduated and began their first year of full-time teaching in schools. Bulletin board discussions of one pre-service cohort are analysed in terms of Wenger’s (1998) three defining features of a community of practice: mutual engagement of participants, negotiation of a joint enterprise, and development of a shared repertoire for creating meaning. Emergence of the online community was associated with our own role in facilitating professional dialogue, the voluntary and unstructured nature of participation, initial face-to-face interaction that created familiarity and trust, and the convenience of using email rather than logging on to a website. The study shows that the emergent design of the community contributed to its sustainability in allowing the pre-service and beginning teachers to define their own professional goals and values.

This paper explores the development of children’s centres in England between 2004 and 2008, focusing on the newly created centres that have been located on primary and nursery school sites. Using both an analysis of policy documents and interview data from three urban local authorities, we examine the use of premises and the differing priorities of centre staff and school heads, particularly in relation to the balance of services between early years education, childcare and family support. We also explore governance issues, focusing especially on patterns of accountability. In so doing, we also examine the tensions that exist between children’s centres located on primary and on nursery school sites and the schools themselves.  相似文献
