This study followed from a previous investigation into the impact of guidance given in writing tasks when six hundred eleven year olds completed writing tasks with varying content and structural support. The aim was to find if the support facilitated better writing and if the nature of the support had differing effects. The findings suggested that the support provided in the stimuli did not significantly affect performance. A qualitative study investigated the reasons why the support did not have a significant effect and explored the factors which affected children as they faced a writing task. ‘Think aloud’ strategies were used to encourage them to verbalise their thoughts as they planned a piece of writing from a given stimulus. The children were then interviewed according to a semi‐structured interview schedule and their planning sheets were also considered. 相似文献

The temporal-difference (TD) algorithm from reinforcement learning provides a simple method for incrementally learning predictions of upcoming events. Applied to classical conditioning, TD models suppose that animals learn a real-time prediction of the unconditioned stimulus (US) on the basis of all available conditioned stimuli (CSs). In the TD model, similar to other error-correction models, learning is driven by prediction errors-the difference between the change in US prediction and the actual US. With the TD model, however, learning occurs continuously from moment to moment and is not artificially constrained to occur in trials. Accordingly, a key feature of any TD model is the assumption about the representation of a CS on a moment-to-moment basis. Here, we evaluate the performance of the TD model with a heretofore unexplored range of classical conditioning tasks. To do so, we consider three stimulus representations that vary in their degree of temporal generalization and evaluate how the representation influences the performance of the TD model on these conditioning tasks. 相似文献

Background: In the recent times of recession and budget cuts, it is more important than ever for library and information services to deliver cost‐effective services. Objectives: This rapid review aims to examine the evidence for the most cost‐effective ways of delivering enquiry services. Methods: A literature search was conducted on LISA (Library and Information Sciences Abstracts) and MEDLINE. Searches were limited to 2007 onwards. Results: Eight studies met the inclusion criteria. The studies covered hospital and academic libraries in the USA and Canada. Services analysed were ‘point‐of‐care’ librarian consultations, staffing models for reference desks and virtual/digital reference services. Conclusions: Transferable lessons, relevant to health library and information services generally, can be drawn from this rapid review. These suggest that ‘point‐of‐care’ librarians for primary care practitioners are a cost‐effective way of answering questions. Reference desks can be cost‐effectively staffed by student employees or general reference staff, although librarian referral must be provided for more complex and subject‐specific enquiries. However, it is not possible to draw any conclusions on virtual/digital reference services because of the limited literature available. Further case analysis studies measuring specific services, particularly enquiry services within a health library and information context, are required. 相似文献

Objectives: To systematically review the UK published literature on e‐learning in the health workplace and to apply the findings to one of the most prolific UK e‐learning initiatives in the health sector—the National Library for Health Facilitated Online Learning Interactive Opportunity (FOLIO) Programme. Methods: Sensitive searches were conducted across assia , Australian Education Index, British Education Index, cinahl , CSA Abstracts, Dissertation Abstracts, Emerald, eric , ibss , Index to Theses, lisa , medline , Psyc Info and Social Science Citation Index. Additional citations were identified from reference lists of included studies and of relevant reviews; citation tracking and contact with experts. Twenty‐nine studies met the inclusion criteria and were coded and analysed using thematic analysis as described by Miles & Huberman (Qualitative Data Analysis: A Sourcebook of New Methods. Newbury Park, CA: Sage, 1984). Results: Five broad themes were identified from the 29 included studies: (i) peer communication; (ii) flexibility; (iii) support; (iv) knowledge validation; and (v) course presentation and design. These broad themes were supported by a total of eleven sub‐themes. Components from the FOLIO Programme were analysed and existing and proposed developments were mapped against each sub‐theme. This provides a valuable framework for ongoing course development. Conclusion: Librarians involved in delivering and supporting e‐learning can benefit from applying the findings from the systematic review to existing programmes, exemplified by the FOLIO Programme. The resultant framework can also be used in developing new e‐learning programmes. 相似文献
