Professional training for designers is crucial in the field of design studies. The characteristics of novices versus those of expert designers have been identified in the literature; however, studies exploring the issue of professional training processes in the actual workplace are not well developed. Our study addresses the topic by using qualitative research methods along with flexible design. Collected data from the interviewees with different work experience were analysed by open, axial and selective coding. Herein, we argue that the processes by which a designer transforms from a novice into an expert in the industry are constructed through the interaction of several complicated factors. The re‐learning inherent in design professions is implemented through knowledge transfer gained from participation in design projects, particularly regarding tacit knowledge. Also, the novice's process of learning and training yields the characteristics and skills that companies and firms require of designers; this process involves a series of disciplinary sub‐processes, from destructive to reconstructive, implemented by employers. In these sub‐processes, the subjectivity of designers is neglected, leading to the suppression of imaginative expression and feelings of alienation among these workers. 相似文献

There is a growing trend toward a consolidation of services for electronic resources management, A–Z journal listings, full text link resolving, and discovery services under a single service provider. In many cases, the adoption of a discovery service from a provider that is not the same as the libraries’ existing link resolver service means managing multiple knowledgebases. In this session, three librarians gave an overview of their experiences and strategies for maintaining separate link resolving and discovery services in lieu of adopting a full suite of services from a single service provider. Each speaker presented a case study on the advantages and challenges of managing their chosen discovery service: EBSCO Discovery Service, Ex Libris’ Primo and ProQuest’s Summon, in conjunction with the CUFTS/GODOT open source knowledgebase and link resolver service. 相似文献

We identified the perceptual–cognitive skills and player history variables that differentiate players selected or not selected into an elite youth football (i.e. soccer) programme in Australia. A sample of elite youth male football players (n?=?127) completed an adapted participation history questionnaire and video-based assessments of perceptual–cognitive skills. Following data collection, 22 of these players were offered a full-time scholarship for enrolment at an elite player residential programme. Participants selected for the scholarship programme recorded superior performance on the combined perceptual–cognitive skills tests compared to the non-selected group. There were no significant between group differences on the player history variables. Stepwise discriminant function analysis identified four predictor variables that resulted in the best categorization of selected and non-selected players (i.e. recent match-play performance, region, number of other sports participated, combined perceptual–cognitive performance). The effectiveness of the discriminant function is reflected by 93.7% of players being correctly classified, with the four variables accounting for 57.6% of the variance. Our discriminating model for selection may provide a greater understanding of the factors that influence elite youth talent selection and identification. 相似文献

A CD-ROM consisting of videos of two lessons by different teachers demonstrating exemplary science teaching was used to elicit,
develop and track the changing conceptions of good science teaching of student teachers enrolled for the one-year Postgraduate
Diploma in Education (PGDE) at several stages during the programme. It was found that the videos acted as an effective probe
to elicit student teachers’ conceptions and had significant impact on those conceptions at different stages of the programme
through the provision of teacher models demonstrating exemplary teaching. The experience has extended novice teachers’ awareness
of alternative teaching methods and approaches not experienced in their own schooling, broadened their awareness of different
classroom situations, provided proof of existence of good practices and prompted them to reflect on their current conceptions
of good science teaching. Most importantly, the strategy of asking student teachers to watch the same videos on three separate
occasions at different times of the course was recognized by them as a crucial element in facilitating their reflection on
their changing conceptions of good science teaching.
PGDE is the standard form of pre-service teacher education in Hong Kong. It provides qualified teacher status within Hong
Kong. Student teachers enrolled for the PGDE have completed a relevant undergraduate degree. 相似文献
