Performance support systems are mechanisms enabling users) productivity while reducing training expenses as support is being delivered in real time, often eliminating the need for costly pre‐performance training. Mobile technologies have created new opportunities for improved performance support systems, especially for tasks performed outside the offi ce. This article describes the fi rst mobile learning and performance support initiative taken by the Israeli Air Force. The project included the development and eff ectiveness pilot study of a learning and performance support application delivered via tablet to helicopter engine technicians. The application provided support videos and illustrations of maintenance routines, thereby enabling learning and practicing at the same time. Pilot study results show high performance levels of application users compared to those applying traditional methods. Results also show that self‐effi cacy levels were not aff ected by the successful performance achieved when using the mobile performance support application. Plans to expand mobile support use are also described.  相似文献

The education of young people with profound and multiple learning difficulties continues to raise challenges and controversies. In this article, Ben Simmons, an ESRC funded PhD student and research assistant, and Phil Bayliss, programme director for the masters degree in special education and disability, both based in the School of Education and Lifelong Learning at the University of Exeter, describe their research into provision for pupils with profound and multiple learning difficulties in a special school in the south west of England. Their work, based in an interpretivist, qualitative approach, set out to illuminate issues relating to the inclusion of pupils with profound and multiple learning difficulties. The findings presented here suggest that the school, in spite of its strong reputation, struggled significantly to provide appropriate learning experiences for pupils with profound and multiple learning difficulties. Ben Simmons and Phil Bayliss discuss the need for improved staff development opportunities focused on enhancing current levels of knowledge and skills. They conclude by calling for a reappraisal of the established view that special schools necessarily provide the best learning environment for pupils with profound and multiple learning difficulties.  相似文献

This study investigated the relations of early working‐memory abilities (phonological and visual‐spatial short‐term memory [STM] and complex memory and episodic buffer memory) and later developing reading skills. Sixty Hebrew‐speaking children were followed from kindergarten through Grade 5. Working memory was tested in kindergarten and reading in Grades 1, 2, and 5. All memory measures, but phonological STM, correlated with reading up to Grade 5. Regression analyses (with intelligence quotient controlled) demonstrated that phonological complex memory predicted all reading skills in Grade 1, and accuracy in Grade 2. The rather understudied visual‐spatial memory predicted comprehension in Grades 2 (STM) and 5 (complex memory). The results point to an important role of the phonological complex memory in early assessment, and suggest a long‐lasting role of early visual‐spatial memory in predicting variance in reading. Whether this role of the visual‐spatial memory is unique to the Hebrew orthography because of its visual features requires, however, further investigation.  相似文献

This article examines the emergence of ‘digital governance’ in public education in England. Drawing on and combining concepts from software studies, policy and political studies, it identifies some specific approaches to digital governance facilitated by network-based communications and database-driven information processing software that are being discursively promoted in education by cross-sectoral intermediary organizations. Such intermediaries, including National Endowment for Science, Technology and the Arts, Demos, the Innovation Unit, the Education Foundation and the Nominet Trust, are increasingly seeking to participate in new digitally mediated forms of educational governance. Through their promotion of network-based pedagogies and database-driven analytics software, these organizations are seeking to delegate educational decision-making to socio-algorithmic forms of power that have the capacity to predict, govern and activate learners' capacities and subjectivities.  相似文献

To explore the citation evolution of papers published in the same year but different month, we selected papers from a discipline (physical geography), a subject (diabetes: endocrine and metabolism) and a journal (Journal of Biological Chemistry) published in 2005 as research objects. These papers were divided into six groups according to the difference in publication month, and we analyzed citations to these papers for the 9 years after publication. The results showed that within 5 years after papers from physical geography were published, the overall differences in citations of papers in different groups were statistically significant (P < 0.05); after that, the differences were not statistically significant. Within 5 years after papers from diabetes (endocrine and metabolism) were published, the overall differences in citations of papers in different groups were statistically significant (P < 0.05); thereafter, the differences were not statistically significant. Within 7 years after papers from the Journal of Biological Chemistry were published, the overall differences in citations of papers in different groups were statistically significant (P < 0.05); thereafter, the differences were not statistically significant. Citations of papers followed the same pattern irrespective of discipline, subject or journal: citations of papers published in the same year but different month were obviously different in the first few publishing years, but as time went on, only the difference in publication month in a calendar year did not affect the papers' longer‐term citation.  相似文献

通过历史资料分析、对比研究、逻辑分析等方法对狩猎、体育以及相关社会问题进行研究,研究认为:狩猎与体育的发展是相辅相成的;狩猎的过程和体育竞赛的过程是高度吻合的,体育竞赛可以视为一种抽象的狩猎活动,而升级、变异的狩猎和体育可能导致战争的发生;在当今社会,商务人士、沉迷于网络游戏的群体以及罪犯,都从事着象征性的狩猎活动,并引发了一系列社会问题。现代社会密集型的体育赛事有缓解人类狩猎欲望和社会冲突的功能,但却又为恐怖袭击和暴乱活动的制造者们提供了良好的"狩猎场所",文明社会如何解决人类的狩猎本能问题还需要进一步的探索。  相似文献
