Reconceptualising educational assessment in South Africa — testing times for teachers     

John Pryor  Cassius Lubisi 《International Journal of Educational Development》2002,22(6)

This paper explores some of the problems arising when Continuous Assessment (CA) is grafted onto established pedagogic practices. It focuses on three issues: teachers' restricted understandings of assessment, teachers' emphasis on criteria that demonstrate concern with social control, and some of the problems connected with peer assessment. Two vignettes derived from fieldwork associated with a project to improve the quality of primary education are used to raise the issues. We argue that the development of desired practices is hampered above all by tacit values in tension with those underpinning the new curriculum. These values, together with the complexity of curriculum design, create serious problems of manageability and interpretation, which can only be addressed through detailed interactive in-service training, aimed at reconceptualising teachers' notions of assessment.  相似文献   

Correlates of verbally aggressive communication in adolescents     

Charles Atkin  Sandi Smith  Anthony Roberto  Thomas Fediuk  Thomas Wagner 《Journal of Applied Communication Research》2002,30(3):251-268

This investigation identifies demographic, media, and social correlates of verbally aggressive communication in adolescence. Mail surveys were completed and returned by 2,300 adolescents between the ages of 13 and 15. These adolescents were asked about the prevalence of verbal and physical aggression, the context in which it occurred, demographics, and the interpersonal and media influences in their lives. The results indicate that verbal aggression is widespread, that committing and experiencing verbal aggression is largely reciprocal, that there is a strong relationship between committing verbal and physical aggression, and that peer social influence and listening to violently oriented music are mildly related to verbal aggression in adolescents. These findings suggest more resources should be allocated to teaching adolescents to understand and control verbal aggression. Further, they provide important answers to many prevention and intervention programmatic questions, including context, content, and targeting concerns. Since the negative consequences of verbal aggression are severe and long lasting, decreasing this destructive communication behavior should significantly improve the lives of many adolescents. These and other practical implications are expanded upon and discussed.  相似文献

同行评议一直是最权威、最有效的科学评价方式,美国、日本、欧盟等发达国家和国际组织都建立较为完整的同行评议制度,制定同行评议政策法规,建立标准化的评议流程,针对不同类型的项目采取不同评议方法。面对科技创新高质量发展的新要求、新任务,本文从加强相关法规体系建设、建立规范化的同行评议准则、构建完善的同行评议专家库、探索因项制宜的同行评议方式、大力营造良好的同行评议生态环境等方面对规范和完善我国同行评议制度提出对策建议。  相似文献   

Creating Better Learners Through Learning Science: A Sample of Methods     

Chris Brown 《图书馆管理杂志》2018,58(4):375-381

This article proposes the incorporation of learning science into the programming and operation of public libraries. Learning science, a multidisciplinary field spanning cognitive science, psychology, neuroscience, economics, anthropology, and linguistics, has identified proven methods for enhancing learning at any age. The article highlights some of the tools and insights that are most relevant to libraries in their role as centers for informal learning.  相似文献   

System-wide improvement of early-grade mathematics: New evidence from the Gauteng Primary Language and Mathematics Strategy     

《International Journal of Educational Development》2016

This article reports on a two-year evaluation of the Gauteng Primary Language and Mathematics Strategy (GPLMS), an innovative system-wide reform intervention designed to improve learning outcomes in Gauteng Province, South Africa. Using data from universal testing of all learners in 2008 on a provincial systemic evaluation, as well as data from the 2011, 2012 and 2013 Annual National Assessment tests, this article investigates whether or not the GPLMS improves the numeracy skills of learners in early-grade mathematics in underperforming schools. Using as identification strategy, the natural experiment that resulted from a miscalculation of the provincial systemic evaluation test scores in 2008, which had been used to assign schools to the GPLMS intervention, the study shows that the GPLMS intervention is positively associated with improvements in early-grade mathematics performance of schools in the neighbourhood around the assignment threshold. The findings of the study contribute to the growing body of knowledge that shows the effectiveness of combining lesson plans, learner resources, and quality teacher capacity building.  相似文献   

Peer victimization,deviant peer affiliation and impulsivity: Predicting adolescent problem behaviors     

《Child abuse & neglect》2016

Abundant evidence has demonstrated an association between peer victimization and adolescent problem behaviors. However, there is a large gap in knowledge about the potential mediators that associate peer victimization with problem behaviors and the potential moderators that exacerbate or buffer this association. The current study examined whether deviant peer affiliation mediated the association between peer victimization and problem behaviors and whether the direct and indirect associations were moderated by impulsivity. A sample of 1401 adolescents (50.1% boys, 11–14 years old) completed anonymous questionnaires regarding peer victimization, impulsivity, deviant peer affiliation, and problem behaviors. Gender, age and socioeconomic status (SES) were controlled for in the analyses. Structural equation models showed that peer victimization was significantly associated with more problem behaviors, and this association was mediated by deviant peer affiliation. Impulsivity moderated both the direct association (peer victimization → problem behaviors) and the second stage of the indirect path (deviant peer affiliation → problem behaviors). Specifically, these associations were especially stronger for adolescents with higher impulsivity. Identifying the processes by which peer victimization is associated with adolescent problem behaviors has important implications for an integrative framework of theory and prevention.  相似文献   

A coach’s political use of video-based feedback: a case study in elite-level academy soccer     

Michael Booroff  Lee Nelson  Paul Potrac 《Journal of sports sciences》2016,34(2):116-124

This paper examines the video-based pedagogical practices of Terry (pseudonym), a head coach of a professional junior academy squad. Data were collected through 6 in-depth, semi-structured interviews and 10 field observations of Terry’s video-based coaching in situ. Three embracing categories were generated from the data. These demonstrated that Terry’s video-based coaching was far from apolitical. Rather, Terry strategically used performance analysis technologies to help fulfil various objectives and outcomes that he understood to be expected of him within the club environment. Kelchtermans’ micropolitical perspective, Callero’s work addressing role and Groom et al.’s grounded theory were primarily utilised to make sense of Terry’s perceptions and actions. The findings point to the value of developing contextually grounded understandings of coaches’ uses of video-based performance analysis technology. Doing so could better prepare coaches for this aspect of their coaching practice.  相似文献
