Curriculum innovation within an evaluative state: issues of risk and regulation     

David Halpin  Marny Dickson  Sally Power  Geoff Whitty  Sharon Gewirtz 《Curriculum Journal》2013,24(3):197-206

The English EAZ experience illustrates the difficulties of developing an innovative, responsive and inclusive curriculum within an evaluative state characterized by high stakes testing. Consequently, while government exhortations to ‘raise standards’, ‘innovate’ and ‘promote social inclusion’ clearly serve an important rhetorical function, they may underestimate the challenges involved and overestimate the capacity of schools within disadvantaged areas to ‘make a difference’.  相似文献   

Beginning teachers as enquirers: m-level work in initial teacher education     

Beth Dickson 《欧洲师范教育杂志》2011,34(3):259-276

In order to deliver life-long learning for teachers, practitioner-based enquiry learning is being promoted by teacher education institutions on the basis that this form of learning gives teachers the ability to understand factors affecting learning within their own classrooms by systematic investigations of issues and the construction of an evidence-base on which decisions which improve learning can be taken. In turn this enhances teacher professionalism. This article presents a study of how practitioner-based enquiry was embedded in an initial teacher education programme; the reasons for this; and the purposes of the strategy, which raised the one-year postgraduate qualification to masters-level. It looks at the reasons for the change; the nature of the change, which included educating teachers intending to teach in primary schools together with those intending to teach in secondary; the introduction of practitioner-based enquiry; some early student reaction; and the structural, cultural and learning issues which have emerged.  相似文献   

Economic returns to education: What We Know, What We Don’t Know, and Where We Are Going—Some brief pointers     

Matt Dickson  Colm Harmon 《Economics of Education Review》2011,30(6):1118-1122

The estimation of the economic return to education has perhaps been one of the predominant areas of analysis in applied economics for over 50 years. In this short note we consider some of the recent directions taken by the literature, and also some of the blockages faced by both science and policymakers in pushing forward some key issues. This serves by way of introduction to a set of papers for a special issue of the Economics of Education Review.  相似文献

Analysis of a laminar-flow diffusional mixer for directed self-assembly of liposomes     

Matthew J. Kennedy  Harold D. Ladouceur  Tiffany Moeller  Dickson Kirui  Carl A. Batt 《Biomicrofluidics》2012,6(4)

The present work describes the operation and simulation of a microfluidic laminar-flow mixer. Diffusive mixing takes place between a core solution containing lipids in ethanol and a sheath solution containing aqueous buffer, leading to self assembly of liposomes. Present device architecture hydrodynamically focuses the lipid solution into a cylindrical core positioned at the center of a microfluidic channel of 125 × 125-μm² cross-section. Use of the device produces liposomes in the size range of 100–300 nm, with larger liposomes forming at greater ionic strength in the sheath solution and at lower lipid concentration in the core solution. Finite element simulations compute the concentration distributions of solutes at axial distances of greater than 100 channel widths. These simulations reduce computation time and enable computation at long axial distances by utilizing long hexahedral elements in the axial flow region and fine tetrahedral elements in the hydrodynamic focusing region. Present meshing technique is generally useful for simulation of long microfluidic channels and is fully implementable using comsol Multiphysics. Confocal microscopy provides experimental validation of the simulations using fluorescent solutions containing fluorescein or enhanced green fluorescent protein.  相似文献   

Reasonable Adjustments in Assessment: Putting Law and Policy into Practice in Australia     

Joy Cumming  Elizabeth Dickson  Amanda Webster 《International Journal of Disability, Development & Education》2013,60(4):295-311

The Australian Disability Standards for Education 2005 (Cth) require education providers to make reasonable adjustments in educational assessment so that students with disability can participate on the same basis as other students and be able to demonstrate what they know and can do. Reasonableness is governed by a determination of the balance of interests, benefits and detriment to the parties involved. The Standards require providers to consult with students and associates on adjustments, although guidance on how consultation should occur and how the views of students and associates are to be taken into account is vague. In this article, we identify three principles to be considered in order to put appropriate and effective reasonable adjustments in assessment into practice. While Australian law and assessment contexts are used to examine intentions, expectations and practices in educational assessment for students with disability, we argue that these three principles must be considered in any national education system to ensure equitable assessment practices and achieve equitable educational inclusion for students with disability.  相似文献   

Competitive balance trends in elite table tennis: the Olympic Games and World Championships 1988-2016     

Jinming Zheng  Seungmo Kim  Geoff Dickson  Veerle De Bosscher 《Journal of sports sciences》2018,36(23):2675-2683

ABSTRACT

Competitive balance is important because it enhances outcome uncertainty and therefore it promotes spectator interest, and encourages government investment in a sport. This article analyses the distribution of gold medals, medals, medal points and top eight points amongst nations in table tennis from 1988 to 2016 at the Olympic Games and the World Championships respectively. A normalised version of the Herfindahl-Hirschman Index and a coefficient of variation are calculated for each nation’s share of these performance indicators. The key findings are that China dominates both events, with successful female players being more dominant than their male counterparts. The competitive balance for gold medals has declined, whilst there is a trend towards improved competitive balance for top eight points for women, suggesting that more teams are featuring in the top eight (but not necessarily the top three) placings. This research has implications for the development of table tennis competitions. Compared to other racket sports, the issue of competitive imbalance in table tennis is particularly thorny, which threatens the long-term development of this sport. Accordingly, some measures are recommended for the International Olympic Committee and the International Table Tennis Federation to propel a more balanced development of international table tennis.  相似文献   

Relative shank to thigh length is associated with different mechanisms of power production during elite male ergometer rowing     

Andrew J. Greene  Michael H. Dickson  Floren Colloud  Richard M. Smith 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(4):302-317

The effect of anthropometric differences in shank to thigh length ratio upon timing and magnitude of joint power production during the drive phase of the rowing stroke was investigated in 14 elite male rowers. Rowers were tested on the RowPerfect ergometer which was instrumented at the handle and foot stretcher to measure force generation, and a nine segment inverse dynamics model used to calculate the rower's joint and overall power production. Rowers were divided into two groups according to relative shank thigh ratio. Time to half lumbar power generation was significantly earlier in shorter shank rowers (p = 0.028) compared to longer shank rowers, who showed no lumbar power generation during the same period of the drive phase. Rowers with a relatively shorter shank demonstrated earlier lumbar power generation during the drive phase resulting from restricted rotation of the pelvic segment requiring increased lumbar extension in these rowers. Earlier lumbar power generation and extension did not appear to directly affect performance measures of the short shank group, and so can be attributed to a technical adaptation developed to maximise rowing performance.  相似文献
