This paper examines the ways in which a culture of performance has impacted on schooling in the English setting and draws parallels with other post‐industrializing nations. There is a growing awareness amongst researchers and practitioners that improving the quality of teaching and learning through performance management is not working. In education policy terms the UK Government has made much of the importance of modernizing the teaching profession in raising levels of achievement, attainment, and success in schools and colleges. The proposed trade‐off for teachers is improved pay for improved standards. Advocates of such reform point to the benefits derived from greater devolution of market principles to frontline professionals which, it is argued, enhance performance, remuneration, and motivation (Barber 2001). Critics, on the other hand, have criticized the deprofessionalizing tendency of tying performance management to government targets, which fail to connect with the contextual realities of teaching and learning in the classroom or education workplace (Elliott 2001, Merson 2001). Recently such criticism was rejected by the (then) Secretary of State for Education as cynicism. ‘In education it is those who offer cynicism in the guise of experience who can drive young teachers to look for other careers. We shall always try to combat cynicism wherever it threatens progress on standards’ (Morris 2001: 9). This paper seeks to avoid such inference by arguing for greater authenticity in the way education practice might drive, rather than being driven by, the policy and performance agenda. 相似文献

ABSTRACT The British government's proposals for the reform of primary initial teacher education (ITE), including the transfer of major responsibility to schools, are examined in the context of their plans for more centralised control over the curriculum and the imposition of traditional methods of teaching. A model of appropriate objectives for school‐based primary ITE is outlined and an alternative concept of partnership based on co‐operation between higher education institutions and schools put forward. Implications of the reforms for primary schools are considered. In an attempt to make sense of the government's proposals, the apparent contradiction between its commitment to an educational market and the actual concentration of power in its own hands is explored. The reforms are shown to be part of a sustained attack on education professionals, and to illustrate how market relations may be used to promote the dominance of the central state by fragmenting opposition. 相似文献

This paper presents mean fatigue lifetime predic- tion of a wire-bond structure model in power electronic module using a failure physics approach that integrates high fidelity modelling and reduced order modelling. Loading current with variable amplitudes is applied to a finite element model of simplified wirebond structures. The resulting accumulated fatigue damage due to random loads is predicted by using reduced order modelling based on failure physics, a cycle counting algorithm, and various nonlinear fatigue damage models widely used in the literature. The reduced order mod- elling approach based on failure physics uses prediction data for the electro-thermo-mechanical behaviour of the wire-bond design of a power module obtained through non-linear transient finite element simulations, in particular for the fatigue life-time of the aluminium wire attached to the silicon chip of the wire in the module. The reduced order models that capture the black box function of the accumulated plastic strain are used in pre- dicting the mean fatigue life time of the wire bond structure under random loads. One of the widely used cycle counting algorithms, rainflow counting algorithm, is used to count cycles of the temperature profile at the specific point of the wire bond structure in a power electronic module. The cycle data from the rainflow algorithm mean life time of the wire bond structure are predicted with various cumulative fatigue models. Non-linear cumulative fatigue models such as damage curve approach (DCA), double linear damage rule (DLDR), and double dam- age curve approach (DDCA), and linear cumulative fatigue damage model such as Palmgren-Miner rule are used to predict the mean fatigue life of the wire bond structure, and the results are compared. 相似文献

The popularity of visual literacy may have resulted, in part, from some school authorities rushing the process of determining school curriculum. This article argues that the haste is reflective of pressure placed on educational discourse to conform to neo-liberal reforms of the sector, and is not the result of a careful and complex debate within the education community. In Australia, such reform has contributed to the erosion of visual art as a discrete subject in the general curriculum. The article accounts for the fact that the lack of careful debate may be due to art educators rehearsing tired arguments for retaining the place occupied by visual art, which smack of sentimentality. The author examines the conceptualisation of visual art at a cultural and theoretical level, and argues that by considering the function art has traditionally played in relation to conceptions of human subjectivity, we may disclose the marginalisation of visual art as a signal of much larger threats to political and economic structures in democratic society. The article considers whether the absorption of ‘art’ within a broader preference for visual communication, graphic design, or design and technology, is symptomatic of a long-term cultural stagnation. 相似文献

The purpose of the present study was to determine the extent to which anxiety sensitivity and speech trait anxiety serve as predictors of state anxiety during public speaking. A model is proposed and tested, in which anxiety sensitivity and speech trait anxiety are found to be significant predictors of state anxiety during public speaking. The model accounted for 43.1% of the variance in the dependent variable. Anxiety sensitivity, or fear of physical sensations or consequences, contributes unique variance to anxiety during public speaking beyond that of trait anxiety alone. Implications for theory development, instruction, and therapy are examined. 相似文献

The optimisation of undulatory underwater swimming is highly important in competitive swimming performance. Nineteen kinematic variables were identified from previous research undertaken to assess undulatory underwater swimming performance. The purpose of the present study was to determine which kinematic variables were key to the production of maximal undulatory underwater swimming velocity. Kinematic data at maximal undulatory underwater swimming velocity were collected from 17 skilled swimmers. A series of separate backward-elimination analysis of covariance models was produced with cycle frequency and cycle length as dependent variables (DVs) and participant as a fixed factor, as including cycle frequency and cycle length would explain 100% of the maximal swimming velocity variance. The covariates identified in the cycle-frequency and cycle-length models were used to form the saturated model for maximal swimming velocity. The final parsimonious model identified three covariates (maximal knee joint angular velocity, maximal ankle angular velocity and knee range of movement) as determinants of the variance in maximal swimming velocity (adjusted-r2 = 0.929). However, when participant was removed as a fixed factor there was a large reduction in explained variance (adjusted r2 = 0.397) and only maximal knee joint angular velocity continued to contribute significantly, highlighting its importance to the production of maximal swimming velocity. The reduction in explained variance suggests an emphasis on inter-individual differences in undulatory underwater swimming technique and/or anthropometry. Future research should examine the efficacy of other anthropometric, kinematic and coordination variables to better understand the production of maximal swimming velocity and consider the importance of individual undulatory underwater swimming techniques when interpreting the data. 相似文献

Though commercial interest in the World Wide Web is growing, the potential uses of the medium as a learning tool are numerous. The GLOBE Visualization Project is one such educational application. We have designed and implemented a WWW-based, user-friendly, language-independent, graphical user interface providing access to visualizations created for GLOBE, a multinational program of education and science. The target users of the system are K–12 students and their teachers from over 1100 schools in 39 countries; other clients include the GLOBE scientific investigators and members of the public internationally. Navigation is intuitive, and employs the metaphors of a Control Panel which changes the image appearing in a Viewscreen. The interface can be learned empirically by persons of all ages regardless of technical expertise or native language; context-sensitive help is provided for users who prefer documentation. The GLOBE Visualization server is on the World Wide Web at URL http://globe.gsfc.nasa.gov/globe/. 相似文献

This paper examines how staff in schools formulate decisions about pupil organisation. A small sample of primary and secondary schools from across Scotland was involved in the study.
In 1996 Her Majesty's Inspectors published a report entitled Achievement for All (SOEID, 1996) which, it was envisaged, would form the basis of school evaluations into the effectiveness of classroom organisation. This report, and in particular the six principles on which it suggested effective organisational arrangements should rest, formed the organising framework for the study.
