It is now widely recognised that Britain's comprehensive system was never truly comprehensive. Families with sufficient financial capital were always able to ensure the entry of their children to particularly prestigious ‘comprehensive’ schools by purchasing a home within the appropriate catchment areas. According to government rhetoric, recent legislation established a market of schools, removed catchment areas and gave parents greater choice of school. This case‐study examines the workings of the local quasi‐market of schools within a prosperous town (Sutton Coldfield, England) which is part of the larger metropolitan area of the West Midlands. Because of a change in the age of entry to secondary education, Sutton Coldfield was first plunged into the market in 1992. This case‐study shows that the new situation initially caused confusion and anger. Some Sutton Coldfield residents were denied places for their children within the town and were instead offered places for their children in Birmingham working‐class estate schools. The article describes the formation and activities of a local pressure group which opposed these changes, and reports the results of a small‐scale study of a sample of parents’ choice‐making processes in 1993. It is shown that access to financial and cultural capital had become more, rather than less, important in the process of allocating children to secondary schools.  相似文献

In education, case studies have been employed as a major pedagogical means to engage students with realistic materials and practical problems. The usefulness and success of case studies have been documented in literature. In this paper, we move the case study and its technical affordance a step further toward more authentic or realistic learning and toward communities of practice. Drawing on current intellectual achievement in education, developmental psychology and computer-supported collaborative learning, this paper proposes four requirements for interactive case study libraries, focusing on authentic learning, social interaction, resource accumulation, and communities of practice. With a usability engineering case study library as an example, we discuss design concerns derived from these requirements as well as its use in practice.  相似文献

Abstract

To determine the energy cost of low impact aerobic dance while varying arm movement height and the use of hand weights, 10 adults volunteered to participate in four choreographed trials. All trials consisted of identical leg movements. Arm movements, however, were performed above shoulder level both with and without 0.9-kg hand weights and below shoulder level both with and without 0.9-kg hand weights. Open circuit spirometry was employed throughout the 10-min videotape guided trials, and heart rate was measured by telemetry. Neither the use of hand weights nor the change in arm position height significantly altered the energy cost of low impact aerobic dance. However, heart rate responses were significantly different. Caution should be observed by aerobics instructors and participants as to the use of heart rate as an indicator of intensity for low impact aerobic dance.  相似文献

This study reports entry-level mathematics attitudes of pre-service primary teachers entering an initial teacher education (ITE) program one decade apart. Attitudes of 360 pre-service primary teachers were compared to 419 pre-service teachers entering the same college of education almost one decade later. The latter experienced reform school mathematics curricula compared to the earlier cohort who experienced traditional curricula. Attitudes were determined by administering Aiken’s Revised Mathematics Attitude Scale (Aiken, 1974). Analyses indicate generally positive attitudes on entry to ITE. The earlier cohort demonstrated greater Enjoyment of Mathematics while the later cohort exhibited higher scores on the Value of Mathematics scale.  相似文献
