As academic library collections are moved off site to make room for learning commons-type collaboration spaces, exploratory research processes (e.g. stacks browsing activities) are threatened. Given the range of benefits associated with chance information encounters in the physical book stacks, the disappearance of accessible collections is problematic. Fortunately, by focusing on embodied aspects of the physical browsing experience we can leverage emerging technologies to preserve instances of serendipitous information retrieval. Virtual reality, in this case, provides a browsing platform that allows for the type of search activity typically associated with research in the physical books stacks and preserves the benefits thereof. 相似文献

INTRODUCTIONAt present, plastic as a substitute for metals in products is the most important mainstay in industrial raw materials. Furthermore, plastic injection molding is one of the most common and versatile methods for mass production of complex plastic parts with excel-lent dimensional tolerance. Since the technology of injection molding has been widely applied in manu-facturing, training on injection molding is of great importance. The traditional approach is to consult some technica… 相似文献

The high drop-out rate in upper secondary education is a major challenge to European and US educational programmes. Upper secondary education in Norway faces a similar challenge, because in recent decades, around one-third of the students drop out of the educational programmes. The majority of the drop-outs are students in vocational programmes, and a substantial number are apprentices at the workplace. With these high drop-out rates and the ensuing personal, social and economic consequences, it is vital to address how upper secondary education systems can keep students connected throughout the programmes. By thoroughly analyzing learning environments and the experiences, interactions and processes which youth deal with during vocational education, insights into how characteristics of the learning environments relate to dropping-out and connectedness may be brought into educational discussions. The case study presented in this article explores how workplaces constitute learning environments and how apprentices participate in the learning environments of work according to their dispositions, aims and life plans. The findings show that the apprentices had different agencies and that they were involved in two distinct participation patterns at the workplace: a collaborative pattern and an executive pattern. Our findings also suggest that strong agency for the vocation may keep apprentices connected throughout the educational programme, although they are aftbrded an executive participation pattern. Based on our findings, it is appropriate to raise questions as to whether an unclear agency for the vocation, together with affordance of executive participation patterns, may suggest one possible answer for the high drop-out rate among apprentices. 相似文献

The paper discusses the approaches of virtual university strategies and developments in Europe. The discussion is partly based on the work done in the Activity 5 in the EU Thematic Network E4 and partly to the experiences gained through the activities of EUNITE virtual university network of six European universities. Based on our experience we see, that e-learning and virtual university approach can be used for renewal of teaching and learning, both on and off campus. Just three years ago, universities seemed mainly to aim only to develop on campus teaching and learning through ICT. Lately, the use of e-learning as a tool for international cooperation and for virtual mobility (Virtual Erasmus) has started to develop through the activities of the European Union e-learning programmes and through the activities of some European university networks, like EUNITE. To promote virtual universities and e-learning, commitment and actions at all levels from EU to individual institutions are needed. 相似文献
