The paper is a theoretical reflection on a research study of ‘Create-A-Scape’, a software resource for making mediascapes
to support learning in the primary and secondary school curriculum. Mediascapes are collections of location-sensitive texts,
sounds and images that are geo-tagged or ‘attached to’ the local landscape, and learners use mobile technologies, such as
PDAs, to roam in a space or landscape to detect and respond to these multimedia tags. The study, commissioned by Futurelab,
was conducted in the summer of 2007 in England. Its aims were to investigate the Create-A-Scape resource and present insights
into its use, perceptions of use, and the implications and potential of mediascape tools for learning, teaching and pedagogy.
A survey of all who had downloaded the software outlined early perceptions and use of the resource. Five selected case studies
were developed through visits, observations and interviews with teachers and pupils using the resources to create mediascape
activities. A cross-case analysis articulated three distinctive theoretical perspectives, namely creativity, teacher knowledge
and a sense of place. The paper presents the conduct and findings of the study, develops the discussion of the theoretical
framework, and considers the potential of such resources for mobile technologies in curriculum integration, and supporting
learning in meaningful physical places. 相似文献

The paper describes a case study of the development and implementation of a policy to monitor teachers’ classroom practice
in a secondary comprehensive school in Wales, UK. The change process is interpreted from an affective standpoint to explain
how the experience of feelings and emotions shapes organisational practice. In particular, the interpretation illustrates
how affective experience may influence the distinction between espoused and in use theories, which may in turn have an effect
on individual and organisational resistance to change and the success of the implementation. Differences between espoused
and in use theories may increase both organisational anxiety and resistance in a self-sustaining cycle. We argue that when
the anxieties and emotions of organising in schools are allowed to surface in the change process and are reflected upon, the
espoused and in use theories are more likely to correspond and organisational anxiety and resistance to change to decrease. 相似文献

Interest in real-time syndromic surveillance based on social media data has greatly increased in recent years. The ability to detect disease outbreaks earlier than traditional methods would be highly useful for public health officials. This paper describes a software system which is built upon recent developments in machine learning and data processing to achieve this goal. The system is built from reusable modules integrated into data processing pipelines that are easily deployable and configurable. It applies deep learning to the problem of classifying health-related tweets and is able to do so with high accuracy. It has the capability to detect illness outbreaks from Twitter data and then to build up and display information about these outbreaks, including relevant news articles, to provide situational awareness. It also provides nowcasting functionality of current disease levels from previous clinical data combined with Twitter data.The preliminary results are promising, with the system being able to detect outbreaks of influenza-like illness symptoms which could then be confirmed by existing official sources. The Nowcasting module shows that using social media data can improve prediction for multiple diseases over simply using traditional data sources. 相似文献

The article examines the process of innovation and knowledge sharing from a perspective that focuses on the influence that local circumstances can have. In particular, it looks at the problems of knowledge sharing between groups of professionals. It presents a comparative analysis of two studies, one involving two groups of IT professionals; the other a network of healthcare professionals. The data was collected in two sets. The first set consisted of the results from two earlier, independent studies; the second was collected specifically for this article. We investigate the role played by boundary objects and brokers. Through an analysis of the interplay between boundary object and broker, we uncover the dynamics of the innovation process and show that the role played by the broker can be political. We identify two strategies that are used by brokers in the selection of a boundary object. The first is directed towards achieving a balance between the actors involved and the second is directed towards controlling their activities. We conclude by suggesting that other researchers should also consider the interplay between broker and boundary object when examining cross-boundary knowledge sharing. 相似文献

Although elite athletes have been reported to be high academic achievers, many elite soccer players struggle with a stereotype of being low academic achievers. The purpose of this study was to compare the academic level (pre-university or pre-vocational) and self-regulatory skills (planning, self-monitoring, evaluation, reflection, effort, and self-efficacy) of elite youth soccer players aged 12-16 years (n = 128) with those of 164 age-matched controls (typical students). The results demonstrate that the elite youth soccer players are more often enrolled in the pre-university academic system, which means that they are high academic achievers, compared with the typical student. The elite players also report an increased use of self-regulatory skills, in particular self-monitoring, evaluation, reflection, and effort. In addition, control students in the pre-university system had more highly developed self-regulatory skills than those in the pre-vocational system, whereas no difference was observed within the soccer population. This suggests that the relatively stronger self-regulatory skills reported by the elite youth soccer players may be essential for performance at the highest levels of sport competition and in academia. 相似文献

Physical therapists seeking to use evidence to guide their practice may have limited time to read research reports. One way to reduce the time required to identify and read about the research that is relevant to a particular clinical question is to read a systematic review that summarizes multiple studies. This paper explains the process that is used to conduct systematic reviews, which includes the establishment of a protocol, comprehensive searching, appraisal of the quality of the included studies, data extraction and metaanalysis, and consideration of the clinical and research implications of the findings. We also consider how the reader of a systematic review can determine whether the review is likely to provide an unbiased (believable) estimate of the treatment effect. A systematic review of randomized trials of a cardiopulmonary physical therapy intervention is used as an example. The issue of appraisal of quality is then discussed further, with a demonstration of how one validated tool for quality appraisal–the PEDro scale–can be used to evaluate a randomized trial in cardiopulmonary physical therapy.Key Words: systematic review, physical therapy 相似文献

This study investigated how changes in the material properties of a landing mat could minimise ground reaction forces (GRF) and internal loading on a gymnast during landing. A multi-layer model of a gymnastics competition landing mat and a subject-specific seven-link wobbling mass model of a gymnast were developed to address this aim. Landing mat properties (stiffness and damping) were optimised using a Simplex algorithm to minimise GRF and internal loading. The optimisation of the landing mat parameters was characterised by minimal changes to the mat's stiffness (<0.5%) but increased damping (272%) compared to the competition landing mat. Changes to the landing mat resulted in reduced peak vertical and horizontal GRF and reduced bone bending moments in the shank and thigh compared to a matching simulation. Peak bone bending moments within the thigh and shank were reduced by 6% from 321.5 Nm to 302.5Nm and GRF by 12% from 8626 N to 7552 N when compared to a matching simulation. The reduction in these forces may help to reduce the risk of bone fracture injury associated with a single landing and reduce the risk of a chronic injury such as a stress fracture. 相似文献

Although teacher–student relationships are assumed to in part reflect early caregiving quality, their social provisions also undergo notable normative change over the course of primary school, shifting from a secure base for social exploration to an instrumental relationship centered on achieving academic goals. This report leveraged prospective, longitudinal data from the Study of Early Child Care and Youth Development (N = 1,306, 52% male, 77% White/non-Hispanic) to investigate whether the association between early caregiving and subsequent teacher–student relationship quality remains stable or diminishes in magnitude over time. Associations between early maternal sensitivity and teacher–student closeness faded from Kindergarten to Grade 6. In contrast, associations between early caregiving and teacher–student conflict endured and were partially accounted for by child externalizing problems. 相似文献

This article considers the impact of Superhighways technology on schools in the UK, in terms of the debate concerning the development of the conditions of postmodernity. In particular, it charts how the collapse of boundaries associated with postmodernism may have affected traditional divisions within schooling, following the introduction of broadband connectivity and Internet capability to schools and colleges. The authors review the broad approaches taken to the introduction of new technologies, such as the Utopian and Dystopian, transformative and incrementalist. By drawing upon the findings of the Education Departments' Superhighways Initiative, the authors explore the effects of new information and communication technologies on a number of traditional boundaries, including those between curriculum subjects, between pupils and teachers, and, more generally, traditional conceptions of space and time. The article concludes that, although initial indications suggest that the impact of Superhighways capability may be a transformative one, the effect on boundaries is mixed. While some boundaries such as those of space and time seem to be dissolving, others such as the division between academic subjects are much more resistant. 相似文献
