Critical pedagogical approaches are underpinned by the principal that education is an inherently political process which should be concerned with enabling students to be reflective, independent, and critical thinkers. In this paper we argue that facilitating the development of a critical consciousness is an integral part of the teaching of critical criminology in higher education. We contend that it is essential if students are to recognize the broader social and political contexts of their own, and others’, lived experiences and thus be able to challenge political oppressions and domain ideologies. By drawing on a pilot study conducted with final‐year undergraduates from a university in the north west of England, the paper will demonstrate how a critical education (critical in terms of subject content, and teaching practice) can better enable students to develop both academically and, as importantly, with regard to their personal, social, and political consciousness. 相似文献

This study examined how self-efficacy and motivation affected student persistence at an urban community college. Self-efficacy was studied at two dimensions: self-regulated learning efficacy and self-efficacy for academic achievement. Motivation was also investigated at two levels: intrinsic motivation and extrinsic motivation. Results show that self-regulated learning efficacy and extrinsic motivation predicted persistence. Intrinsic motivation and academic achievement self-efficacy failed to predict persistence directly. Two path models were constructed to assess the direct and indirect relationships among self-efficacy, motivation, and persistence. The reduced model explained 8% of the variance in persistence. In the reduced model, extrinsic motivation emerged as a mediator in the relationship between the two dimensions of self-efficacy and persistence. It was also found that self-efficacy measures correlated well with motivation measures. Implications and limitations of the research findings are discussed. 相似文献

The purpose of the paper is to explore Students' perception of university teaching behaviours in Pakistan. Three hundred and fifty students from the six public sector Pakistani universities returned questionnaires. Assessment framework, learning activities and instructional strategies emerged from factor analysis as common factors. Students' views on five conceptual variables were also analysed: instructional design, active teaching, learning activities, questioning styles; and assessment framework. University teaching in Pakistan was found to be driven by assessment. This is a matter of concern for all stake holders, including the administration of the universities, teachers, students and the Higher Education Commission. A teaching behaviour paradigm shift is required, switching from knowledge-oriented teaching behaviour focused on successful passage through assessment, to teaching behaviour focused upon the development of transferable skills demanded by external markets. 相似文献

This paper aims to solve the problem of sliding mode control for an uncertain two-dimensional (2-D) systems with states having time-varying delays. The uncertainties in the system dynamics are constituted of mismatched uncertain parameters and the unknown nonlinear bounded function. The proposed problem utilizes the model transformation approach. By segregating the proper Lyapunov–Krasovskii functional in concert with the improved version of Wirtinger-based summation inequality, sufficient solvability conditions for the existence of linear switching surfaces have been put forward, which ensure the asymptotical stability of the reduced-order equivalent sliding mode dynamics. Then, we solve the controller synthesis problem by extending the recently proposed reaching law to 2-D systems, whose proportional part is appropriately scaled by the factor that does not depend on some constant terms but rather on current switching surface’s value, which in turn ensures the faster convergence and better robustness against uncertainties. Finally, the proposed results have been validated through an implementation to a suitable physical system. 相似文献

Research on the adoption of systems for big data analytics has drawn enormous attention in Information Systems research. This study extends big data analytics adoption research by examining the effects of system characteristics on the attitude of managers towards the usage of big data analytics systems. A research model has been proposed in this study based on an extensive review of literature pertaining to the Technology Acceptance Model, with further validation by a survey of 150 big data analytics users. Results of this survey confirm that characteristics of the big data analytics system have significant direct and indirect effects on belief in the benefits of big data analytics systems and perceived usefulness, attitude and adoption. Moreover, there are mediation effects that exist among the system characteristics, benefits of big data analytics systems, perceived usefulness and the attitude towards using big data analytics system. This study expands the existing body of knowledge on the adoption of big data analytics systems, and benefits big data analytics providers and vendors while helping in the formulation of their business models. 相似文献

A Degree Apprenticeship model has recently been introduced into the United Kingdom (UK) Higher Education system as part of wider changes to vocational training. The system has experienced numerous rapid changes in regulation and funding, and it is now little understood by many stakeholders. Distinguishing different phases in UK Higher Education, and using a salience model as a lens for analysis, this article identifies and examines stakeholders with regards to their influence on the Higher Education curriculum. The new Degree Apprenticeship model is funded by an employer payroll levy and it requires Higher Education institutions to deliver training to specific standards. This research explores the implications of the model for the Higher Education curriculum, concluding that the direct involvement of employers in the design and delivery of vocational Higher Education introduces untried elements into UK Higher Education on the assumption that the funding requirement will lead to a change in employer behaviour. This, coupled with the opening of Higher Education provision to private providers, transfers power over the curriculum to those with potentially no commitment to wider public values, and may offer a threat to the international standing of UK Higher Education. This article contributes to research in understanding how Higher Education systems respond to, and actors cope with, imposed change. 相似文献

We present design, characterization, and testing of an inexpensive, sheath-flow based microfluidic device for three-dimensional (3D) hydrodynamic focusing of cells in imaging flow cytometry. In contrast to other 3D sheathing devices, our device hydrodynamically focuses the cells in a single-file near the bottom wall of the microchannel that allows imaging cells with high magnification and low working distance objectives, without the need for small device dimensions. The relatively large dimensions of the microchannels enable easy fabrication using less-precise fabrication techniques, and the simplicity of the device design avoids the need for tedious alignment of various layers. We have characterized the performance of the device with 3D numerical simulations and validated these simulations with experiments of hydrodynamic focusing of a fluorescently dyed sample fluid. The simulations show that the width and the height of the 3D focused sample stream can be controlled independently by varying the heights of main and side channels of the device, and the flow rates of sample and sheath fluids. Based on simulations, we also provide useful guidelines for choosing the device dimensions and flow rates for focusing cells of a particular size. Thereafter, we demonstrate the applicability of our device for imaging a large number of RBCs using brightfield microscopy. We also discuss the choice of the region of interest and camera frame rate so as to image each cell individually in our device. The design of our microfluidic device makes it equally applicable for imaging cells of different sizes using various other imaging techniques such as phase-contrast and fluorescence microscopy. 相似文献

Tomography is traditionally associated with medical ‘CT’ scanners that have been in use for over 30 years now. This mathematical
concept is now applied widely by scientists and engineers in a variety of measurements involving solids, fluid, gases and
plasmas. Instrumentation based on X-rays, gammarays, lasers and acoustics have been used successfully in these applications.
Inherent error in such measurements can be also be estimated thus making tomographic imaging a very powerful non-invasive
technique for field measurements.

Listening to children’s views of spiritual and metaphysical concepts: A new dimension to educational psychology practice? 总被引:1,自引:1,他引:0
Irvine Gersch Fiona Dowling Georgia Panagiotaki Anita Potton 《Educational Psychology in Practice》2008,24(3):225-236
Educational psychologists (EPs) have for many years been developing techniques for listening to children. The aim of the present research was to investigate ways of listening to the “spiritual” views of children in order to develop questions that educational psychologists might use as part of the assessment repertoire. The study explored children’s spiritual concepts such as their purpose for “being on the planet” and the “meaning of their life”. The findings suggest that primary and secondary school children from mixed religious backgrounds can respond to spiritual questions in a clear way. In addition, most children believed that spiritual views influence how children behave. Further research is required to explore whether children’s views of spiritual concepts are linked to learning and progress in school and in life. 相似文献
