Taking the distinction between the Institution of Apprenticeship, that is, the social partnership arrangements which underpin its organisation, and Apprenticeship as a Social Model of Learning, in other words, he configuration of pedagogic and occupational etc. dimensions which constitute the model, as its starting point the paper: (i) argues the emergence of de-centred, distributed and discontinuous conditions associated with project-work present challenges for extant ideas about apprenticeship as a social model of learning; (ii) explores this claim in relation to Fuller and Unwin’s four inter-connected dimensions of apprenticeship as a social model of learning by considering a case study of apprenticeship designed to prepare apprentices to work in the above conditions; (iii) relates issues arising from the case study to research on project work from the fields of Organisational and Cultural Studies; and (iv) based on this evidence base introduces a typology of ‘Apprenticeship for Liquid Life’.  相似文献

There is widespread consensus in the research and policy‐related literature over the last decade that young people who have been permanently excluded from school are at a far greater risk of a variety of negative outcomes than young people who have not had this experience. These negative outcomes include prolonged periods out of education and/or employment; poor mental and physical health; involvement in crime; and homelessness. This article presents evidence from a small‐scale qualitative study of destinations and outcomes post‐exclusion for a group of young people considered to be at particular risk of such negative outcomes: namely, those who have been permanently excluded from special schools or Pupil Referral Units (now known as short‐stay schools). The specific focus of this paper is on the 24 young people's educational trajectories pre‐ and post‐exclusion; the reasons for their exclusion from school; and on what forms of alternative provision were available to them after their permanent exclusion.  相似文献

Many user-centred studies of electronic information resources include a think-aloud element – where users are asked to verbalise their thoughts, interface actions and sometimes their feelings whilst using these resources to help them complete one or more information tasks. These studies are usually conducted with the purpose of identifying usability issues related to the resource(s) used or understanding aspects of users’ information behaviour. However, few of these studies present detailed accounts of how their think-aloud data was collected and analysed or provide detailed reflection on methodological decisions made. In this article, we discuss and reflect on the methodology used when planning and conducting a think-aloud study of lawyers’ interactive information behaviour. Our discussion is framed by Blandford et al.’s PRET A Rapporter (‘ready to report’) framework – a framework that can be used to plan, conduct and describe user-centred studies of electronic information resource use from an information work perspective.  相似文献

The collection, organization, and long-term preservation of resources are the raison d??être of archives and archivists. The archival community, however, has largely neglected science data, assuming they were outside the bounds of their professional concerns. Scientists, on the other hand, increasingly recognize that they lack the skills and expertise needed to meet the demands being placed on them with regard to data curation and are seeking the help of ??data archivists?? and ??data curators.?? This represents a significant opportunity for archivists and archival scholars but one that can only be realized if they better understand the scientific context.  相似文献

As new media technologies and platforms emerge and take hold in our society, traditional publishers are wondering: What’s in this new content climate for me? The simple answer is: a lot. The digital world, mobile content delivery mechanisms and the public’s increasing comfort—even preference for—a media menu from which they can pick and choose what they want and how they want to receive it, brings exciting and potentially lucrative opportunities. For publishers who understand how to leverage their brand and create authentic, identifiable value in the eyes of the customer, risk can be reduced and new revenue streams built. Here are four best practices to position your publishing company for growth.  相似文献

During backstroke, an optimum shoulder entry angle of 180° has been anecdotally suggested; however, this has yet to be investigated biomechanically. The aim of this study was to quantify shoulder entry angles for advanced and intermediate backstroke swimmers. Six advanced (season's best?<150?s) and six intermediate (season's best?>160?s) 200-m backstroke swimmers had markers applied to the medial humeral epicondyles and glenoid cavities. Following a familarization period, participants completed backstroke swimming trials (90?s each) in a swimming flume at 50%, 60%, 70%, and 80% of their season's best 200-m velocity. A camera positioned above the flume recorded frontal plane motion, which was digitized and analysed in Simi Motion Systems. The mean peak angle between the upper arm and the line of progression was established in ten strokes for each participant. The results showed backstroke shoulder entry angles for advanced swimmers (170°) were significantly closer to the suggested optimum 180° compared with those of intermediate swimmers (161°). The non-dominant arm displayed values closer to the optimum (171°), while swimming speed had no effect on backstroke shoulder entry angle. In conclusion, backstroke shoulder entry angle may help discriminate between advanced and intermediate backstroke swimmers and may be influenced by laterality dominance, being independent of swimming speed.  相似文献

This is part of a new series in this regular feature regarding trends in the provision of information by health science libraries. By sharing expertise and drawing together relevant trends the series intends to serve as a road map for both health science librarians and health informatics professionals. This article shows how a medical and biomedical research library changed practices, and reassessed user needs for the COVID‐19 emergency. Discusses changes to online education (and collaborative working) to provide user‐friendly services, researcher support tailored to need and re‐visioning library space. J.M.  相似文献

It is an accepted fact that resilience is a multifaceted phenomenon which has been proven to affect the learning, growth and development of individuals. A child’s formative years are a time when resilience needs to be promoted so they can cope with the challenges of life. This paper reports some of the findings of an Australian Research Council-funded longitudinal study which investigated resilience in the context of significant transitions in the lives of children and young adults. This study explored the conditions and characteristics of resilience, looking at the educational, health, work-related or leisure interventions that support and foster resilience. Outlined in this paper are findings from the early years cohort of the study involving teachers’ pedagogy informing the practical approaches and strategies that promote and protect resilience in young children. It is argued that teachers working with young children need to be mindful of using enabling strategies in which their practice works purposively with the school environment and the building of relationships.  相似文献

In this article, we explore how youth audiences evaluate the quality of youth-produced films. Our interest stems from a dearth of ways to measure the quality of what youth produce in artistic production processes. As a result, making art in formal learning settings devolves into either romanticized creativity or instrumental work to improve skills in core content areas. We conducted focus groups with 38 youth participants where they viewed four different films produced by the same youth media arts organization that works with young people to produce short-form, autobiographical documentaries. We found that youth focused their evaluations on identifying the films' genre and content and on assessing how well the filmmakers' creative decisions fit with identifications of genre and content. Evaluations were mediated by audiences' expectations and seemed to inform judgments of quality and creativity. We hope that our work can inform the design of formal learning spaces where young people are producing narrative art.  相似文献
