The effects of accountability measures in English secondary schools: early and multiple entry to GCSE Mathematics assessments     

Rachel Charlotte Taylor 《牛津教育评论》2016,42(6):629-645

This study used semi-structured interviews with staff in 14 secondary schools in England to explore strategies for entering students to GCSE Mathematics, focusing on the use of early and multiple examination entry. The key findings suggest that teachers were keenly aware of performativity pressures and that this prompted the use of a number of strategic entry practices, including the frequent use of early entry to allow students multiple examination attempts. This approach aimed to maximise the number of students achieving a grade C, the threshold for school accountability measures and for accessing further education and employment opportunities. Widespread use of early and multiple entry is likely to cease in England following amendments to accountability measures announced in 2013, yet this study adds a further perspective to the well-established literature detailing the impact of accountability measures in schools, as well as depicting teachers’ views on the effects of early and multiple entry upon pupils’ education.  相似文献   

The relationship between A-level subject choice and league table score of university attended: the ‘facilitating’, the ‘less suitable’, and the counter-intuitive     

Catherine Dilnot 《牛津教育评论》2018,44(1):118-137

Abstract

English students from less privileged backgrounds and state, rather than private, schools remain significantly under-represented at high-status universities. There has been little work to date on the role of A-level subject choice, as opposed to attainment, in access to university. Using linked administrative data for three recent cohorts of English entrants to UK universities, I examine the relationship between league table score of university attended and A-level subject choices, using a taxonomy of A-levels categorised according to their published efficacy for Russell Group university admission as ‘facilitating’, ‘useful’, or ‘less suitable’. I further examine the relationship of three ‘less suitable’ A-levels with league table score of university for related degree courses commonly leading to professional business careers (accountancy, business, and law). Holding more facilitating A-levels is associated with attending a higher ranked university overall, even controlling for degree subject, and the converse is true for ‘less suitable’ subjects. The heterogeneous relationships of professionally-related A-level subjects with university ranking make decision-making for aspirational 16-year-olds problematic: an apparently sensible subject choice for students wishing to prepare for a professional career may, in fact, put them at a disadvantage.  相似文献   

Policy transfer,sustainable development and the contexts of education     

Michael Crossley 《Compare》2019,49(2):175-191

As comparative and international researchers in education we are especially well placed to contribute to the analysis and understanding of global trends in both education and international development. In times of ever increasing complexity and uncertainty it can also be argued that we have a responsibility to do so, and to do so in rigorous but accessible ways. In this Presidential Address I: (1) consider how we might do this in the light of the BAICE 2018 Conference theme; (2) argue how and why the critical interrogation of the processes of educational policy transfer lie at the heart of this; and (3) draw upon work inspired by BAICE during its first 20 years, along with my own related research in a diversity of contexts worldwide.  相似文献   

The importance of adjusting for pupil background in school value-added models: A study of Progress 8 and school accountability in England     

George Leckie  Harvey Goldstein 《British Educational Research Journal》2019,45(3):518-537

In the UK, USA and elsewhere, school accountability systems increasingly compare schools using value-added measures of school performance derived from pupil scores in high-stakes standardised tests. Rather than naïvely comparing school average scores, which largely reflect school intake differences in prior attainment, these measures attempt to compare the average progress or improvement pupils make during a year or phase of schooling. Schools, however, also differ in terms of their pupil demographic and socioeconomic characteristics and these factors also predict why some schools subsequently score higher than others. Many therefore argue that value-added measures unadjusted for pupil background are biased in favour of schools with more ‘educationally advantaged’ intakes. But others worry that adjusting for pupil background entrenches socioeconomic inequities and excuses low-performing schools. In this article we explore these theoretical arguments and their practical importance in the context of the ‘Progress 8’ secondary school accountability system in England, which has chosen to ignore pupil background. We reveal how the reported low or high performance of many schools changes dramatically once adjustments are made for pupil background, and these changes also affect the reported differential performances of regions and of different school types. We conclude that accountability systems which choose to ignore pupil background are likely to reward and punish the wrong schools and this will likely have detrimental effects on pupil learning. These findings, especially when coupled with more general concerns surrounding high-stakes testing and school value-added models, raise serious doubts about their use in school accountability systems.  相似文献
