It is suggested that sport is not only popular but also plays a highly significant part in the lives of many. One explanation focuses on the analysis of the tension excitement generated by sporting encounters. Particular emphasis is placed on the work of Elias and Dunning, who suggest that in societies at a late stage in the “civilising process,” affect-control is strongly established, so that people's expressions of sentiment are strongly restrained. Excitement in such societies is thus to be found not so much in real-life situations as through mimetic or “imitative” excitement, which resembles that produced in critical situations in real life, but in a safe and pleasurable way. A second approach draws on a variety of theoretical perspectives, although the contributions derived from Emile Durkheim's later work on the sociology of religion are prominent. The argument is advanced that sports encapsulate symbolically the social natures, relations, and identities of the collectivities that generate them. Sport, therefore, is perceived as a form of collective representation that may be invested with great social significance. Finally, relationships between the two approaches are considered.  相似文献

We designed Knowledge Integration Environment (KIE) debate projects to take advantage of internet resources and promote student understanding of science. Design decisions were guided by the Scaffolded Knowledge Integration instructional framework. We report on design studies that test and elaborate on our instructional framework. Our learning studies assess the arguments students construct using the Knowledge Integration Environment debate project about light propagation and, explore the relationship between students' views of the nature of science and argument construction. We examine how students use evidence, determine when they add further ideas and claims and measure progress in understanding light propagation. To a modeate degree, students' views of the nature of science align with the quality of the arguments.  相似文献

This research investigates the inherent dilemma evident in attempts to promote decentralization initiatives in urban public schools. Detroit provides a natural experiment in decentralized education reform given both the collaborative and the competitive reform efforts that were advanced between 1988 and 1994. A collaborative partnership, the Detroit Compact, was created, and schools of empowerment and choice were partially implemented, conceptually designed to enlarge the community role in the operation of the schools. Results indicate that efforts at promoting decentralization, over time may produce counterpressures to recentralize decision making.  相似文献
