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

Peer assessment is recognised as a useful learning activity, not merely as a means by which assignments can be marked. In a design subject such as Human-computer Interaction, peer-assessment offers a unique opportunity for students to be exposed to a wide range of different designs in an environment that ensures that they reflect on these designs. However, it is important that the marking criteria are well specified and unambiguous. This paper reports on the use of peer-assessment as an effective learning activity for revealing the wide range of design issues and dimensions in interface design, where formal marking is based on clear, functional criteria. Subjective consideration of the interfaces is encouraged through a ranking system and the subsequent elicitation of interface design principles. The successful implementation of this scheme demonstrates its benefits both as a learning activity and as an opportunity for student reflection.  相似文献

In England, the presence of an established church places its adherents within the social mainstream. Other religious groups have been tolerated though suffering social and educational disadvantages. With the passage of time through the nineteenth and twentieth centuries, minority religious groups such as Irish Catholics have been assimilated into the host culture, and allowed to have their own schools.
However, it would appear that contemporary movements of people to the United Kingdom have retained loyalties not only to their own religion, but, in some instances to their own language, which they perceive as a vital element of their own culture and identity. Demands for schools, within the state-funded system, for minority religious groups have not lessened. As faith schools in England increase in number, their role in a multicultural society becomes increasingly problematic. Lessons about changing models of assimilation and identity can be learnt from a brief review of the historic Irish Catholic experience that, in turn, can illuminate the current experience of a Greek Orthodox school in south London.  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

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
