This paper presents the findings from one of the first empirical research studies which has investigated the impact of Inter-Life; a novel three-dimensional immersive virtual learning environment, on learning and development of social and educational life transition skills in a group of looked after and accommodated children. Drawing on social constructivism in which meaningful learning is related to context and situated in practice, we report on a series of Inter-Life workshops that enabled young people to work together and through the processes of participation in authentic learning activities contributed to the development of life transition skills such as self-confidence, empathy, negotiation and mediation skills, teamwork and active problem-solving skills. The novel affordances of the Inter-Life virtual world which contributed to the development of the learning community included the ability to personalise learner engagement and activities from the outset along with ‘co-presence’ and ‘immersion’ and the flexibility provided by the innovative, technology-enhanced Inter-Life platform. This study presents some empirical evidence to demonstrate the efficacy of new models of learning that are mediated by innovative malleable technologies that can be shaped by the learner in a participatory manner. 相似文献

This paper examines one particular response of the Canadian government to the issue of multi‐ethnicity in higher education: the constraints placed on people of Indian origin with regard to attendance at universities until the 1950's, and traces the historical development of special programmes within universities for Indian students. It suggests that while special programmes for Indian students may be a positive step in terms of Indian control of Indian education and the development of an infrastructure for both self‐government and economic development, such programmes are nevertheless problematic. In particular, special programmes tend to reinforce negative and potentially racist stereotypes about Indian culture. They suggest that Indian people trained in special programmes are only capable of dealing with other Indian people. The degrees granted by special programmes are devalued by employers. State efforts to increase the level of education amongst Indian people are aimed at creating a new set of agents of social control. 相似文献

Abstract In this paper we outline an analytical approach to identifying points in the policy process where management intervention to adjust organizational design could enhance delivery of innovation policy over time. We illustrate this approach using an example from native vegetation policy in the state of Victoria, Australia. We then use this approach to interpret recent reviews of the Australian Cooperative Research Centres (CRC) Program, a policy instrument aimed at enhancing national economic growth by fostering innovation in research and development. The approach described in this paper is grounded in the idea of policy as a complex and adaptive organizational system. From the findings it was apparent that reviews of the Australian CRC Program have recognized some of its complex and dynamic properties. However, they have been limited in their capacity to translate this recognition into practical recommendations for organizational design to improve delivery on innovation, particularly in relation to the uptake of research outputs by industries such as agriculture. We propose that this is likely to reflect the bureaucratic foundations of innovation policy and the difficulties associated with changing processes and ways of managing them that have become locked in to the organizational system. The design of policy instruments to deliver innovation, such as the CRC Program, should be informed by a detailed understanding of the dynamics that are mediating between policy objectives and outcomes over time. Dynamics such as the impact of bureaucratic constraints on the flexibility of policy processes and the participants engaged in them. In the absence of this sort of understanding, dynamics that critically affect the capacity of policy instruments to deliver innovation are likely to go unidentified and left to run their own course to an unpredictable and potentially counterproductive end. While the idea of policy as a complex organizational system is well known, there remains a substantive gap in knowledge as to how thinking about policy in this way might be applied to generate practical options for improving organizational design. The analytical approach described in this paper addresses this gap in knowledge. In the absence of such approaches, the effectiveness of policy instruments such as the CRC Program, which are intended to foster innovation, will continue to be limited by deficiencies in organizational design. 相似文献

A network-centric university teaching and research environment based around mobile robots is described. It supports teaching a wide spectrum of computer science and engineering subjects (e.g., digital electronics, computer architecture, operating systems, communications, distributed processing, software engineering, machine vision, artificial intelligence, embedded computer design, real-time computing, HCI, computer graphics, virtual reality, etc.) within a single unified experimental environment. This enables students to combine their coursework so as to build more complex, interesting and industrially relevant systems, thereby significantly increasing their motivation and knowledge. The laboratory infrastructure makes extensive use of networks to produce a versatile and cost effective teaching and research environment. This paper will focus on the teaching aspects of the laboratory, describing the technical infrastructure and showing how it is used to support the Essex Un! iver sity information technology curriculum and report on the effectiveness of the approach. Finally, to demonstrate the more general academic synergy provided by this laboratory a short overview of some of the research applications is presented. 相似文献

Earlier research revealed that many elderly people in The Netherlands are worried about their forgetfulness and are afraid of incipient dementia. Until now, no systematic research has been conducted on the effects of public education about normal forgetfulness and dementia, and therefore an information brochure was developed and evaluated. The main function of this brochure was to reassure people who were unnecessarily worrying about possible dementia. A second function was to motivate people to seek professional help when this seemed advisable. Sixty‐two percent of all respondents (307 of 400) who had been worried about dementia before reading the brochure said that their anxiety decreased or disappeared after reading it; approximately 3% became more worried after reading the brochure. A cognitive test battery was administered to 104 people to determine whether their increased or decreased anxiety was justified. Thirty subjects had low test scores, yet 16 of these subjects had been reassured by the brochure that their forgetfulness was nothing to worry about. This group was characterized as experiencing fewer problems in daily life as a result of their forgetfulness and as having a higher internal locus of control. Seventy‐four subjects performed well on the cognitive tests, yet 18 of them had remained worried about their forgetfulness after reading the brochure. Anxiety for heredity of dementia could be a possible explanation for their persistent concern. Although many people were reassured by the brochure, the results also show that it is important to evaluate information brochures used as intervention instruments—in one third of the present sample, the effects of the brochure were not in accordance with its goal. 相似文献
