Income Level, Gender, Ethnicity, and Household Composition as Predictors of Children''s School-based Competence 总被引:5,自引:0,他引:5
In the United States, being black, male, or growing up in a low-income and/or single-parent household have all been identified as risk factors for maladjustment during childhood. Interpretation of these findings is, however, often difficult because of the well-known associations among these variables. In the present study, we compared predictions of 3 different forms of children's competence from each of these 4 variables. In a sample of 868 black and white elementary school children from 2-parent and mother-headed 1-parent homes, we studied 3 aspects of school-based competence: conduct, peer relations, and academic achievement. Results showed that although the independent variables accounted for different amounts of variance in each domain of competence, income level and gender were better overall predictors of children's competence in conduct and peer relations than were ethnicity or household composition. Income level and ethnicity were better overall predictors of academic achievement than were gender or household composition, although each of the 4 variables made a significant contribution. Overall, income level and gender were thus the strongest predictors of children's competence. Black children were, however, more likely than white children to live in low-income homes. Our results thus highlighted some correlates of the unequal distribution of economic resources among black and white children growing up in the United States today. 相似文献

This paper reports on a study involving the identification and measurement of collaboration in an online asynchronous discussion (OAD). A conceptual framework served for the development of a model which conceptualises collaboration on a continuum of processes that move from social presence to production of an artefact. From this model, a preliminary instrument with six processes was developed. Through application of the instrument to an OAD, the instrument was further developed with indicators added for each process. Use of the instrument to analyse an OAD showed that it is effective for gaining insight into collaborative processes in which discussants in an OAD do or do not engage. Use of the instrument in other contexts would test and potentially strengthen its reliability and provide further insight into the collaborative processes in which individuals engage in OADs. Analysis of an OAD using the instrument revealed that participants engaged primarily in processes related to social presence and articulating individual perspectives, and did not reach a stage of sharing goals and producing shared artefacts. The results suggest that the higher‐level processes related to collaboration in an OAD may need to be more explicitly and effectively promoted in order to counteract a tendency on the part of participants to remain at the level of individual rather than group or collaborative effort. 相似文献

The acquisition of early mathematical knowledge is critical for successful long-term academic development. Mathematical language is one of the strongest predictors of children's early mathematical success. Findings from previous studies have provided correlational evidence supporting the importance of mathematical language to the development of children's mathematics skills, but there is limited causal evidence supporting this link. To address this research gap, 47 Head Start children were randomly assigned to a mathematical language intervention group or a business-as-usual group. Over the course of eight weeks, interventionists implemented a dialogic reading intervention focused on quantitative and spatial mathematical language. At posttest, students in the intervention group significantly outperformed the students in the comparison group not only on a mathematical language assessment, but on a mathematical knowledge assessment as well. These findings indicate that increasing children's exposure to mathematical language can positively affect their general mathematics skills. This study is an important first step in providing causal evidence of the importance of early mathematical language for children's general mathematical knowledge and the potential for mathematical language interventions to increase children's overall mathematics abilities. 相似文献

ABSTRACTThis article explores the lived realities for young people growing up and learning in a climate of racial discrimination, religious intolerance, misogyny, and xenophobia, and how school-sponsored and school-supported uses of digital media can afford young people opportunities to navigate their experiences of social injustice and resist exclusionary discourses and practices. In a collaborative inquiry into the practices of two youth media producers, we explore how these counternarrative efforts are forms of restorying, in which young people write themselves into existence in ways that can reconfigure school spaces. Framed in Black feminist and critical cosmopolitan perspectives, this article considers how young people use new media tools in school to engage the narrative imagination and build the worlds they want to live in, simultaneously representing the political histories and realities of their everyday worlds and imagining alternative futures. We explore the ways schools can create opportunities for youth to engage in these new media practices that re-author themselves and the institutional spaces they encounter – and how these opportunities are situated within broader intersectional forms of systemic inequity and oppression. 相似文献

The paper gives a brief overview of the use of digital video in distance education, the background to The Open University's Digital Video Applications (DiVA) Project, the contexts in which the Digital Video Library system is being used and some evaluation findings. Through DiVA, the university is investigating how it can use its video assets effectively, to support reuse of existing materials in course production. The project team is also evaluating student use of the system. The paper reports on an observation study which revealed several usability issues and stakeholders' opinions about potential uses of the DiVA system. This is followed by findings from an evaluation of student use of the system at a residential school and its use as part of an online learning activity undertaken by students accessing the system remotely. Evaluation findings to date indicate some quality and workload issues but they also show opportunities that come to light when using the DiVA system. 相似文献

An overview of information ethics issues in a world-wide context 总被引:2,自引:0,他引:2
Elizabeth A. Buchanan 《Ethics and Information Technology》1999,1(3):193-201
This article presents an overview of significant issues facing contemporary information professionals. As the world of information continues to grow at unprecedented speed and in unprecedented volume, questions must be faced by information professionals. Will we participate in the worldwide mythology of equal access for all, or will we truly work towards this debatable goal? Will we accept the narrowing of choice for our corresponding increasing diverse clientele? Such questions must be considered in a holistic context and an understanding of the many levels of information inequities is requisite. Beginning with an historical perspective, Buchanan presents Mustapha Masmoudi's seminal review of forms of information inequities. She then describes qualitative forms of inequities, such as information imperialism and cultural bias embedded in such practices as cataloging and classification. Following, a review of quantitative inequities is presented. Such issues as the growing commoditization of information and information services demand attention from the ethical perspective. And, finally, the Internet and implications surrounding the world-wide dissemination of information is discussed. The article concludes with an extraction form Richard Sclove's Democracy and Technology, and asks that we as information professionals actively examine the information industry around us and demand a more democratic process within which to work. 相似文献

Two important sets of performance indicators have become established in the United Kingdom: research quality ratings and teaching quality ratings. The research quality ratings and, to a lesser extent, the teaching quality ratings, influence the level of government funding provided to higher education institutions. This paper considers the correlation between the two ratings and the possible consequences of policies that reshape the higher education sector by concentrating research resources in a limited number of institutions. Comparisons are made between quality assurance/assessment approaches in the United Kingdom and those in the United States. 相似文献

Driven by claims of efficacy, flexibility and resource effectiveness, higher education is increasingly utilising the Web as an instructional tool. The claims for pedagogical effectiveness are often just that – claims — and appear not to have been proven in the reality of subject presentation and evaluation. Thus, it is necessary to examine assumptions regarding the benefits of Web‐based instruction in terms of effectiveness. This article discusses aspects of an investigation which examined and compared the effectiveness of HIV/AIDS related collaborative tutorial activities carried out in both a Web‐based learning environment and a face‐to‐face class situation within an undergraduate health education subject. Effectiveness of the pedagogical strategy and the different learning environments were measured in terms of observed learning outcomes and reported perceptions of the learners regarding their learning experience. Preliminary results based on measured learning outcomes related to the subject matter, HIV/AIDS, demonstrated that collaborative learning activities were significantly more effective in the Web‐based than in the class environment. Additionally, the vast majority of learners perceived the Web‐based environment to be as effective or more effective than the face‐to‐face, class environment in terms of facilitating their understanding of the issues explored in the subject. 相似文献
