School disciplines,social representations,and the construction of the didactics of history,geography, and civics 总被引：1，自引：0，他引：1
The author presents a concept of the didactics of history, geography, and civics that seeks to link, through a single dynamic, the civic, political, and social goals of school knowledge with everyday classroom practice and pupils' learning. Two concepts occupy the heart of this construction: those of school disciplines and social representations. The concept of school disciplines addresses the fact that school knowledge is a creation of the school, designed to enable it to achieve the social goals it is assigned. A school discipline is thus a particular combination of goals, content (in the form of shared knowledge), methods, and practices. The concept of social representations is a tool serving to analyze knowledge as theories of the natural and social world, its production, and its reception by the different actors involved. 相似文献

It has been widely documented that accountability systems, including school inspections, bring with them unintended side effects. These unintended effects are often negative and have the potential to undo the intended positive effects. However the empirical evidence is limited. Through a European comparative study we have had the rare opportunity to collect empirical evidence and study the effects (both intended and unintended) of school inspections (a key system of accountability) in a systematic way, across seven countries. We present the findings of the unintended effects in this paper. Survey self-report responses from school principals in each country, with differing school inspection systems, are analysed to measure the prevalence of these unintended effects and to investigate the part played by pressure to do well in inspections. A key finding is that increasing pressure in school inspection systems is associated with the undesired effect of the narrowing and refocusing of the curriculum and instructional strategies. We also show that a proportion of school principals admit to misrepresenting the school in data sent to the inspectorate and show evidence for formalisation/proceduralisation (excessive focus on records) and ossification (fear of experimentation in teaching), although these factors are less related to changes in pressure. 相似文献

Research involving standardized reading achievement tests has been widespread, but there has been little investigation into the relationships among the more widely used tests of reading achievement. In the present study, the Reading subtest of the WRAT, the Reading Comprehension subtest of the PIAT, and the SORT were compared with each other and with the WISC-R. Results showed a high correlation between the WRAT and the PIAT, a moderately high correlation between the SORT and the PIAT, and a very low correlation between the SORT and the WRAT. The WRAT and the PIAT had higher correlations with the various components of the WISC-R than did the SORT. These findings imply that the WRAT and the PIAT measure essentially the same dimension of reading achievement, possibly verbal fluency, but that the SORT is measuring a different dimension, one that is also tapped to some extent by the PIAT. 相似文献

Hyper-femininity and the construction of the ‘girly girl’ label have been documented widely, but there has been less attention to their content (or any distinctions between these constructs). Indeed, it can be argued that the content of femininity remains a controversial and somewhat under-researched topic in feminist scholarship. This is also the case in relation to science, which has been widely characterised as a masculine terrain, but there has been less attention to why femininity is excluded from/by science. This article attempts to unpick some of these issues, with a particular focus on the construct of the ‘girly girl’, in relation to access to science. Drawing on qualitative data from the Economic and Social Research Council-funded ASPIRES 2 project, we analyse the discourses used by young people and parents in discussion of ‘girly girls’ and physics. We show the misogynist and excluding discourses projected onto the ‘girly girl’, and indeed that are used to interpolate femininity more broadly. We found that in discussions of science and (hyper-)femininity, even potentially positive feminine attributes were denigrated. Hyper-femininity was produced as ‘more than lack’: vacuous, but also a risible presence. In reflecting on our findings we consider whether femininity may be more derided in some discursive contexts (e.g. science discourse) than others, and whether femininity can or should be conceived as more than lack. 相似文献

Two education reports commissioned by the United Nations Educational, Scientific and Cultural Organization (UNESCO), Learning to be, otherwise known as the Faure report (1972) and Learning: The treasure within, otherwise known as the Delors report (1996), have been associated with the establishment of lifelong learning as a global educational paradigm. In this article, which draws on archival research and interviews, I will explore how these two reports have contributed to debates on the purpose of education and learning. In the first half, I will shed light on their origins, the context in which they came about, how they have been received by the education community and by UNESCO member states and how they have been discussed in the scholarly literature. In the second half, I will discuss the key themes of the reports, in particular lifelong learning as the global educational ‘master concept’. In the last section, I will reflect on how the Faure report and the Delors report are still relevant for our debates about learning today. I will argue that the concept of lifelong learning, as put forward by these reports, was a political utopia which is at odds with today's utilitarian view of education. 相似文献

《Journal of moral education》2012,41(4):430-442
Here the author takes ren-humanity to be, as Confucius says, an underlying, ineffable, potentially universal human quality, and draws a distinction between three different types of moral capacity in the Lunyu: the man of ren’s capacity for li-proper interactions, his capacity for total reciprocity with another, and his capacity to make moral discriminations. The nature of these moral judgments is then discussed in relation to the praxis of entering into shu-reciprocity with another and that of recognizing others’ actions as being li-proper. A key question is that of whether even an intuitive feeling of commonality, if not identity, with another man-of-ren involves a subjective judgment. Confucius’ view that foreigners can respect ren even if they may not possess it is also discussed. The author suggests that any viable ethical model would need to maintain a universal standard of humaneness while also including a maximum degree of openness to the other. 相似文献
