This study examined the contributions of the different components of the working memory (WM) model to a range of mathematical skills in children, using measures of WM function that did not involve numerical stimuli. A sample of 148 children (78 Year 3, mean age 8 years and 1 month, and 70 Year 5 pupils, mean age 9 years and 10 months) completed WM measures and age‐appropriate mathematics tests designed to assess four mathematical skills defined by the National Curriculum for England. Visuo‐spatial sketchpad and central executive, but not phonological loop, scores predicted unique variance in children’s curriculum‐based mathematical attainment but the relative contributions of each component did not vary much across the different skills. Subsequently, the mathematics data were re‐analysed using cluster analysis and new performance‐related mathematics factors were derived. All three components of WM predicted unique variance in these performance‐related skills, but revealed a markedly distinct pattern of associations across the two age groups. In particular, the data indicated a stronger role for the visuo‐spatial sketchpad in the younger children’s mathematics performance. We discuss our findings in terms of the importance of WM in the development of early mathematical ability.  相似文献

Internationally, the quality of teachers is a growing focus of educational reform, with new policies attempting to ensure that only the ‘best and brightest’ are selected for the teaching profession. This article tests the assumption underpinning these developments that prospective teachers lack the desired academic and personal qualities. Drawing on data on the career aspirations of 6492 Australian school students in Years 3–12, we investigated who, among these students, expressed interest in teaching and their reasons for doing so. Using logistic regression, we found that interest in teaching was widespread and prior academic achievement was not a significant predictor. Thematic analysis of reasons expressed for interest in teaching indicated that working with children and/or in specific subject areas, altruism, and perceptions of personal suitability for the job dominated student responses. These data provide a counter-narrative to the primacy, in policies for teacher recruitment and selection, of needing to attract ‘better’ students. We argue that policies for improving teacher quality should also capitalise on the widespread interest in teaching among school students. Without such a discursive broadening, we caution that current attempts to attract the ‘best and brightest’ risk undermining the very goals espoused.  相似文献

The view taken in this article is that Total Quality Management (TQM) in the new universities (the former Polytechnics) and the development of a so‐called managerialist ideology has led to the inevitable adoption of an approach to Human Resource Management (HRM) policy and practice that is functionalist. The criteria favoured by managerialism represented by TQM is not only inappropriate in higher education, but more importantly, it limits the productive activity of individuals. This limitation occurs to the extent that at the level of the individual academic in higher education organizations, quality control and assurance, that has traditionally been a localized process of self‐ and close‐peer review, has become formalized by externally imposed systems and procedures ‐ a necessary condition under the current funding arrangements for enabling internal quality assurance systems to meet the requirements of external agencies. However, the authors suggest that only a truly professionalizing, soft, individualistic, and user‐focussed collegial culture will provide a sufficient condition for total quality enhancement to become a reality.  相似文献

Most of us in the Western world are accustomed to learning about the world primarily through our senses of sight and hearing. Despite a few interesting experiments in the education of the "lower" senses, smell, taste and touch have not been accorded a place in mainstream Western education. These senses tend to be associated either with "savagery" or sensualism. When we look across cultures, however, a different sensory picture emerges, in which each of the senses has a vital role to play in the acquisition of knowledge of the world. The example is taken of the Desana people of the Colombian rainforest. For the Desana the sound of every bird call, the colour and scent of every flower, the taste of every fruit is imbued with a message about the social and cosmic order. The Desana remind us in the modern West that knowledge does not just come from books and computers, it comes from the full-bodied experience and interpretation of our environment.  相似文献

The purpose of this study was to investigate the development of preservice science teachers’ knowledge structures in the domain of oxidation and reduction chemistry. Knowledge structures were elicited through video-recorded semi-structured interviews before and after the unit of instruction, and analyzed using a visual flow map representation. Paralleling these interviews, the preservice teachers were tasked with diagnosing middle school students’ scientific understandings. Data analyzed quantitatively and qualitatively showed large variation in knowledge structure complexity across the preservice teachers, strong correlations between measures of knowledge structure and diversity (as defined by the Shannon Wiener diversity index), and the development of more balanced knowledge structure representations. For most preservice teachers, their diagnostic scores of the middle school students showed a small increase.  相似文献
