Whereas history is seen by some as crucial in developing a sense of identity and fostering social cohesion, it is however, often based around narrowly nationalistic views of the past, and yet little is known about how students relate to the past they are taught. Thus, this paper focuses on the history curriculum and the ways in which students aged 12–14, from different ethnic backgrounds, relate to it. Moreover, the small-scale study which enabled this paper, focused, in particular, on whether students enjoyed and valued history and whether they felt any sense of personal connection to the topics studied. Drawing on survey data collected from 102 students and focus group discussions with 42 students, from two high schools, the findings indicate that although many students enjoy history, they fail to fully understand its value. Additionally most students, especially those from minority ethnic backgrounds, feel a lack of personal connection to the past, as they do not see themselves in the history they are taught.  相似文献

Though the themes in Howards End and Mrs.Dalloway are many and varied,the master theme is a connection of fragments and divergences,and the powerfully drawn female characters have long been the focus in the interpretation of the theme of the novels.In this paper,tentative conclusions are drawn that connection the heroines have seemingly fulfilled in the end is problematic for its vulnerability and superficiality through a careful study of narrative techniques in the molding of Mrs.Wilcox and Mrs.Dalloway;and that such problematic connection revealed in the human relationship is,to some extent,the expression of an ambiguous stance of Forster and Woolf towards the definiteness of connection in a modern binary world.  相似文献

By the resultant theory, the E-characteristic polynomial of a real rectangular tensor is defined. It is proved that an E-singular value of a real rectangular tensor is always a root of the E-characteristic polynomial. The definition of the regularity of square tensors is generalized to the rectangular tensors, and in the regular case, a root of the E-characteristic polynomial of a special rectangular tensor is an E-singular value of the rectangular tensor. Moreover, the best rank-one approximation of a real partially symmetric rectangular tensor is investigated.  相似文献

A case is made for working in higher education across and between disciplines, variously known as inter- and multidisciplinarity. Integrativism is proposed as an inclusive term for these different but related modes of academic work. Working integratively is presented as a creative activity. The application of integrativism to the curriculum leads to the notion of a pedagogy of connection. Sociocultural theory is a theoretical foundation for a pedagogy of connection which consists of a framework for focusing on the contexts of connection and tools for making connections. Activity theory is the basis of analysing context and analogy and conceptual blending are examples of tools. The pedagogy of connection is demonstrated through the example of a sense of place. The example takes the form of a design experiment.  相似文献
