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

Cyril Smith’s distinguished career in industrial metallurgy was wonderfully transformed into his masterful engagement with
the history of science and technology. These two phases were bridged by a piece of research that particularly pleased him,
as epitomising his general ideas of form and organisation. It was based on his conception of the 2D soap froth as a prototype
for metallic grain growth (and much else). He rightly sensed that it would be an enduring source of understanding of some
of the complex effects that he so admired in materials. 相似文献

We describe an elaboration of an empirical cognitive model of reflection (McAlpine, Weston, Beauchamp, Wiseman, & Beauchamp, 1999). Specifically, we explain 2 fundamental constructs in the model that were previously less well understood: goal and type of reflection. 相似文献

Four experiments examined the utility of real-time text in supporting deaf students' learning from lectures in postsecondary (Experiments 1 and 2) and secondary classrooms (Experiments 3 and 4). Experiment 1 compared the effects on learning of sign language interpreting, real-time text (C-Print), and both. Real-time text alone led to significantly higher performance by deaf students than the other two conditions, but performance by deaf students in all conditions was significantly below that of hearing peers who saw lectures without any support services. Experiment 2 compared interpreting and two forms of real-time text, C-Print and Communication Access Real-Time Translation, at immediate testing and after a 1-week delay (with study notes). No significant differences among support services were obtained at either testing. Experiment 3 also failed to reveal significant effects at immediate or delayed testing in a comparison of real-time text, direct (signed) instruction, and both. Experiment 4 found no significant differences between interpreting and interpreting plus real-time text on the learning of either new words or the content of television programs. Alternative accounts of the observed pattern of results are considered, but it is concluded that neither sign language interpreting nor real-time text have any inherent, generalized advantage over the other in supporting deaf students in secondary or postsecondary settings. Providing deaf students with both services simultaneously does not appear to provide any generalized benefit, at least for the kinds of materials utilized here. 相似文献

The problem of position tracking of a mini drone subject to wind perturbations is investigated. The solution is based on a detailed unmanned aerial vehicle (UAV) model, with aerodynamic coefficients and external disturbance components, which is introduced in order to better represent the impact of the wind field. Then, upper bounds of wind-induced disturbances are characterized, which allow a sliding mode control (SMC) technique to be applied with guaranteed convergence properties. The peculiarity of the considered case is that the disturbance upper bounds depend on the control amplitude itself (i.e. the system is nonlinear in control), which leads to a new procedure for the control tuning presented in the paper. The last part of the paper is dedicated to the analysis and reduction of chattering effects, as well as investigation of rotor dynamics issues. Conventional SMC with constant gains, proposed first order SMC, and proposed quasi-continuous SMC are compared. Nonlinear UAV simulator, validated through in-door experiments, is used to demonstrate the effectiveness of the proposed controls. 相似文献

OBJECTIVE: To meet the information needs of isolated primary care providers and their patients in the US Navy, a digital health sciences library, the Virtual Naval Hospital, was created through a unique partnership between academia and government. METHODS: The creation of the digital library was heavily influenced by the principles of user-centered design and made allowances for the nomadic nature of the digital library's patrons and the heterogeneous access they have to Internet bandwidth. RESULTS: The result is a digital library that has been in operation since 1997, continues to expand in size, is heavily used, and is highly regarded by its patrons. CONCLUSIONS: The digital library is dedicated to delivering the right information at the right time to the right person so the right decision can be made, and therefore the Virtual Naval Hospital functions as a knowledge-management system for the US Navy Bureau of Medicine and Surgery. 相似文献
