We provide an economic assessment of the operation of schooling quasi-markets, re-interpreting the findings of the mainly sociologically-based empirical research. We find that economic analysis is complementary to that of sociology, providing further explanations for the failure of greater competition to increase the diversity of provision and challenge traditional school hierarchies. 相似文献

Evaluating Corrective Feedback Self‐Efficacy Changes Among Counselor Educators and Site Supervisors 下载免费PDF全文
Analysis of pretest–posttest scores on the Corrective Feedback Self‐Efficacy Instrument (Page & Hulse‐Killacky, 1999 ) following a supervision workshop indicated a significant positive relationship between workshop training and supervisors' feedback self‐efficacy in giving corrective feedback. Furthermore, the association between prior supervision training, supervision experience, and feedback self‐efficacy was measured. Practical and research implications are discussed. 相似文献

In countries such as the UK, schools have a responsibility to prevent all forms of bullying, including those related to sexual orientation. However, relatively little is known about how schools go about this work successfully. This study aimed to identify how three secondary schools in south London, England, were addressing homophobia. Three different kinds of schools – a co-educational, boys' and girls' school – were selected, each known to have conducted work to counter homophobic bullying. In each school, interviews were conducted with staff and pupils. Work on homophobia and homophobic bullying was said by most staff respondents to be part of a general commitment to countering bullying. Pupils stated that they were keen that homophobic bullying should be tackled – and distinguished bullying from ‘cussing’, ‘taking the mick’ and ‘mucking about’. Work carried out in schools had influenced pupils to consider homophobia and its effects – although the media as well as personal and family relationships were also important in this respect. Findings are discussed with regard to ways in which schools might better align what they do with regard to pupils' own values and understandings about how best to address homophobia and bullying. 相似文献

With children using digital media at ever younger ages, media-education becomes a pressing issue for parents. As there is hardly any research on how parents guide the online activities of toddlers and young children an internet-survey was held among 792 Dutch parents of children aged between 2 and 12 years. Factor analysis revealed that for the internet, parents partly use the same strategies they also apply for television and video games: ‘co-use’, ‘active mediation’, and ‘restrictive mediation’. In addition, they also utilise new strategies: ‘supervision’ and ‘technical safety guidance’. Mediation was mainly predicted by the child's age and online behaviour (e.g., gaming, social networking), as well as by the number of computers in the home and the parents' gender, education and computer/internet skills. Finally, parents also use more mediation when they expect that the internet has a positive effect and particularly when they believe that it has a negative impact. 相似文献

The reverse k-nearest neighbor (RkNN) problem, i.e. finding all objects in a data set the k-nearest
neighbors of which include a specified query object, has received increasing attention recently. Many
industrial and scientific applications call for solutions of the RkNN problem in arbitrary metric spaces
where the data objects are not Euclidean and only a metric distance function is given for specifying
object similarity. Usually, these applications need a solution for the generalized problem where the
value of k is not known in advance and may change from query to query. In addition, many applications
require a fast approximate answer of RkNN-queries. For these scenarios, it is important to generate
a fast answer with high recall. In this paper, we propose the first approach for efficient approximative
RkNN search in arbitrary metric spaces where the value of k is specified at query time. Our approach
uses the advantages of existing metric index structures but proposes to use an approximation of the
nearest-neighbor-distances in order to prune the search space. We show that our method scales significantly
better than existing non-approximative approaches while producing an approximation of the true query
result with a high recall. 相似文献
