Privatisation,Decentralisation and Education in the United Kingdom: The Role of the State 总被引:1,自引:0,他引:1

Since the early 1950s, the axis centralisation–decentralisation, especially as thematised in the work of Isaac Kandel, has represented a major focus of comparative studies in education. Kandel argued that issues relating to the internal conduct of the classroom (interna ) should, so far as possible, be decentralised, while issues relating to administration, school structure and organisation of the educational system (externa ) might safely be centralised. After 1988, successive governments in the United Kingdom have undertaken reforms which have placed more central control on the curriculum and even methods of teaching (interna ), while school finance and administration (externa ) have been devolved to the school level. The present essay argues that a simplistic approach to centralisation and decentralisation is not likely to be fruitful. Instead, we should acknowledge the role of the State in creating a permissive framework for educational systems. Local action can then be seen as part of a policy accommodating or resisting the implications of that framework. 相似文献

This article reports on a study that investigated the extent to which central ministry policy initiatives result in large‐scale educational change in developing countries. Specifically, Lesotho's policy of inclusive special education was examined as a case study. The study employed a multi‐method approach to yield a large data‐set. Results indicate that policy implementation was limited in both depth (the approaches to inclusive education in some schools) and breadth (the number of schools that have received training in inclusive education). Where implementation was present, perceived teacher knowledge and skill was a strong predictor of success and teachers had positive attitudes toward children with disabilities. 相似文献

Dissertation committees are complex social arenas that underscore expertise, image, and peer relationships—all of which affect
professional identity and advancement. This study presents a sampling of how early career women faculty members learn about
and negotiate their participation on dissertation committees. Research questions focused on participants’ concerns about the
social and political aspects of participation viz à viz peer relationships and faculty rewards. We analyzed interview data
using both holistic and constant comparative methods, resulting in a working model of active participation across three domains:
knowledge, access, and membership. We also identified developmental trends of dissertation committee engagement across the
early career. 相似文献

Herman Witkin's research in differentiation theory proposed a conceptual framework describing the cognitive style known as field dependence‐independence. The operational measures of this construct are restructuring skills and interpersonal competencies, and were originally conceived to be fixed in an individual. A recent reconceptual‐isation, however, suggested that there may be some malleability in learning strategies that flow from cognitive style. Learners predisposed to field dependence might gain access to restructuring skills brought to problem‐solving situations by field independents. This study undertook to examine the effects and practicability of restructuring training as a means of addressing individual learner differences. Field independent subjects significantly out‐scored field‐dependent subjects on all three test tasks in the control group. Experimental group field independents did not significantly outscore experimental field dependents. Training enhanced field dependent subject performance on two dependent measures tasks. There was interaction across treatment and field dependence on all three dependent measures. 相似文献

OBJECTIVE: Children's Advocacy Centers (CACs) aim to improve child forensic interviewing following allegations of child abuse by coordinating multiple investigations, providing child-friendly interviewing locations, and limiting redundant interviewing. This analysis presents one of the first rigorous evaluations of CACs' implementation of these methods. METHODS: This analysis is part of a quasi-experimental study, the Multi-Site Evaluation of Children's Advocacy Centers, which evaluated four CACs relative to within-state non-CAC comparison communities. Case abstractors collected data on investigation methods in 1,069 child sexual abuse cases with forensic interviews by reviewing case records from multiple agencies. RESULTS: CAC cases were more likely than comparison cases to feature police involvement in CPS cases (41% vs. 15%), multidisciplinary team (MDT) interviews (28% vs. 6%), case reviews (56% vs. 7%), joint police/child protective services (CPS) investigations (81% vs. 52%) and video/audiotaping of interviews (52% vs. 17%, all these comparisons p<.001). CACs varied in which coordination methods they used, and some comparison communities also used certain coordination methods more than the CAC with which they were paired. Eighty-five percent of CAC interviews took place in child-friendly CAC facilities, while notable proportions of comparison interviews took place at CPS offices (22%), police facilities (18%), home (16%), or school (19%). Ninety-five percent of children had no more than two forensic interviews, and CAC and comparison differences on number of interviews were mostly non-significant. CONCLUSIONS: Relative to the comparison communities, these CACs appear to have increased coordination on investigations and child forensic interviewing. The CAC setting was the location for the vast majority of CAC child interviews, while comparison communities often used settings that many consider undesirable. CACs showed no advantage on reducing the number of forensic interviews, which was consistently small across the sample. 相似文献

There are many influences on how assessors grade themselves and others. Oral presentations are useful for exploring such factors in peer, self‐ and tutor marked assessments, being rapidly completed and assessed, commonly used in HE and very difficult to anonymize. This opportunistic study examined the effects of gender and level of attainment on the triangulation of marks awarded to student presenters. Grades generated by peer assessment were associated more strongly with tutor‐awarded marks than those from self‐assessment. For self‐assessment there was a strong effect of gender (female students undervalued their performance compared with tutor grades). Peer assessment produced higher marks than from tutors, perhaps because of the close‐knit community developed during residential courses. For tutor marks, the greatest variability was at the lower end of the scale, whereas peer assessors were most variable when marking students who self‐evaluated or peer assessed highly. Students awarded a narrower range of marks to peers compared with tutors, but when self‐assessing used a larger range. Presentations by students who admitted to little sleep the night before received lower grades from both peers and tutors, but this was not reflected by self‐assessments, suggesting they were unaware of their poorer performances. Sessions with fewer talks (four rather than seven) reduced the ‘dip’ in marks previously observed in the middle of sessions. Findings are discussed in the context of bias in this mode of assessment. 相似文献

This study utilized early reading assessment data from a randomized trial of 210 urban and rural schools in Texas to examine
contextual effects on risk prediction in first and second grade. The primary objective was to examine the roles of (a) individual
differences, (b) the grade 1 classroom, and (c) the pairing of first and second grade teachers in determining grade 2 outcomes
in word reading and fluency. A second objective was to investigate whether the administration format of the assessment (paper,
paper plus desktop, handheld plus desktop) or the level of teacher support (web mentoring, no mentoring) moderated the prediction.
These moderator variables proved not to be significant. Subsequent analyses found that a combination of student pretest and
mean of pretest classroom was a better predictor than student pretest alone. Additionally, the effect of student scores varied
by teacher-pair. On average, intraclass correlations (ICCs) ranged from 6% to 17%. Differences in ICCs at the classroom level
were much greater than at the school level, and differences in urban schools were twice that of rural schools. 相似文献

When searching for health information, results quality can be judged against available scientific evidence: Do search engines return advice consistent with evidence based medicine? We compared the performance of domain-specific health and depression search engines against a general-purpose engine (Google) on both relevance of results and quality of advice. Over 101 queries, to which the term ‘depression’ was added if not already present, Google returned more relevant results than those of the domain-specific engines. However, over the 50 treatment-related queries, Google returned 70 pages recommending for or against a well studied treatment, of which 19 strongly disagreed with the scientific evidence. A domain-specific index of 4 sites selected by domain experts was only wrong in 5 of 50 recommendations. Analysis suggests a tension between relevance and quality. Indexing more pages can give a greater number of relevant results, but selective inclusion can give better quality. 相似文献
