After a decade of virtual learning environments (VLEs) in higher education, many teachers still use only a minimum of its affordances. This study looked at how academic staff interacted with a new and unknown VLE in order to understand how technology acceptance and support materials influence (perceived and actual) task performance. In an experimental design, 36 participants were split into a control (online help) and experimental (instructor video) condition and completed five common teaching tasks in a new VLE. In contrast to most technology acceptance model research, this study found that perceived usefulness of the VLE was not related to (perceived) task performance. Perceived ease of use was related to intentions and actual behaviour in the VLE. Furthermore, no significant difference was found between the two conditions, although the experimental condition led to a (marginal) increase in time to complete the tasks. 相似文献

It is widely assumed that there is an eccentric hamstring muscle fibre action during the swing phase of high-speed running. However, animal and modelling studies in humans show that the increasing distance between musculotendinous attachment points during forward swing is primarily due to passive lengthening associated with the take-up of muscle slack. Later in the swing phase, the contractile element (CE) maintains a near isometric action while the series elastic (tendinous) element first stretches as the knee extends, and then recoils causing the swing leg to forcefully retract prior to ground contact. Although modelling studies showed some active lengthening of the contractile (muscular) element during the mid-swing phase of high-speed running, we argue that the increasing distance between the attachment points should not be interpreted as an eccentric action of the CE due to the effects of muscle slack. Therefore, there may actually be no significant eccentric, but rather predominantly an isometric action of the hamstrings CE during the swing phase of high-speed running when the attachment points of the hamstrings are moving apart. Based on this, we propose that isometric rather than eccentric exercises are a more specific way of conditioning the hamstrings for high-speed running. 相似文献

A large number of studies in CMC have assessed how social interaction, processes and learning outcomes are intertwined. The present research explores how the degree of self-determination of learners, that is the motivational orientation of a learner, influences the communication and interaction patterns in an online Problem Based Learning environment. Given the complexity of CMC, we expected that autonomous learners would be more willing to contribute to cognitive discourse. In time, we expected that control-oriented learners would develop a preferential attachment to contribute to discourse from autonomous learners. Data were gathered from 37 autonomous and 39 control-oriented learners who posted 1669 messages. Using a dynamic multi-method approach of content analysis of cognitive and social discourse, social network analysis, and measures of academic motivation, we find some preliminary evidence that motivational orientation influences communication and social interaction patterns amongst learners. From the beginning, most control-oriented learners develop a preference to connect to and communicate with autonomous learners, although a separate team-analysis indicates that group dynamics also influence how learners develop connections with other learners in time. Our findings further the understanding of differences found in distance learning courses about participation and drop-out. 相似文献

This paper discusses the reciprocal relationships among globalization, information and communication technologies (ICT), and the prospect of a ‘global village’. The current metaphor of a ‘global village’ (regardless of physical access to ICT) is problematic, and can be interpreted as a form of electronic colonization. However, through such concepts as blurred identity, nomadism, and hybridity, a distinctly (post‐modern) ICT landscape can be redrawn in a way that accepts the global identity of the ICT, but denies the colonial erasure associated with the global‐village narrative. ICT, in themselves, cannot serve as an end in education, but the demand for critical education involving ICT is pressing as the effects of globalization are experienced. Three methods of promoting decolonizing criticality are proposed: critical emotional literacy, collective witnessing, and collective intelligence. 相似文献

The current difficulties of scholarly publishing are set out and a response to them based upon publishing by the institutions of the authors involved is described. An account of the role of the FIGARO Project in facilitating such a response is then given. 相似文献

Owing to the growing internationalisation of research, educational researchers in the Netherlands are increasingly expected to publish through the medium of the English language. Though this undoubtedly benefits the communication between scholars, there are also side-effects. This paper discusses problematic issues from three perspectives: (i) the use of a non-native language for communication between scholars in the area of education; (ii) the use either exclusively, or not, of a publication record of such publications for purposes of recruitment and promotion of staff; (iii) the relationships between research groups of different disciplines and/or universities. It will be argued that the demand to publish exclusively in a non-native language has damaging effects as far as the context of education is concerned. Not only will it lead to a denial of one's own background and culture, but the uniformisation, (which is the result of it), will also stifle the rich educational landscape by allowing the publication only of items of international interest. The model of the natural sciences is not adequate for the context of education because of the necessarily more local character of the content of educational problems and production of strategies to deal with these. Thus it will become clear that the integrity of the educational researcher is at stake as the research area is selected. 相似文献

Innovation in a professional organization 总被引：1，自引：0，他引：1
The innovation of academic programs has been an issue of considerable interest in higher education policy in the Netherlands during the past five years. Both university administration authorities and the minister of education have tried to stimulate the innovation of academic programs by creating incentives.This article evaluates two innovative projects at the University of Utrecht, and the role of incentives in these particular cases. The results of this evaluation are then reconsidered from a theoretical point of view. Conclusions are formulated with respect to the extent to which innovation can be stimulated, and the kind of incentives suitable for this purpose.This article is a revised version of a paper presented at the 9th European Forum of the Association for Institutional Research, Enschede, The Netherlands, August 24–26, 1987. 相似文献
