The methodology of protecting the European stained glass windows against environmental risk (e.g. meteorological factors, air pollution, microorganisms) by means of an external glazing is not new. In spite of many scientific studies carried out in the last 20 years, some questions were still up for discussion. The European VIDRIO (2002–2005) project gave an answer to these questions. The research carried out by the different project partners established a new multidisciplinary approach aimed at evaluating the efficiency of the protective glazing systems and their effects on stained glass windows conservation, and finally at assessing the most appropriate strategy to preserve stained glass windows. Scientific results showed that the so-called isothermal glazing (i.e. ventilation by the air coming from the inside of the building) protected efficiently the ancient stained glass window from environmental attack (i.e. rain, pollutants, condensation, thermal shocks) with very limited secondary effects. The scientific research highlighted that its efficiency was strongly related to the technical design of the protective system. In particular, the ventilation and the size of the interspace had to be carefully considered. The research developed within the VIDRIO project was turned into general recommendations to the owners and practitioners on the best practice for the stained glass windows future conservation. 相似文献

Coopetition, i.e., cooperation between competing actors, has become a pervasive strategy for innovative firms. The primary focus of studies investigating coopetition centers on inter-firm relationships, highlighting the benefits, limits and configurational patterns of cooperative relationships between competing firms. Only a small, emerging group of studies seeks to extend the concept to the intra-firm level, stressing the existence and effects of competition and cooperation between units that are part of the same organization. This paper contributes to this latter group by investigating the effects of internal coopetition on knowledge and innovation sharing and highlighting the fundamental role of knowledge brokers in managing the resulting tensions. Based on a qualitative case study of the video game publisher Ubisoft, we stress how the tensions raised by internal coopetitive settings limit knowledge sharing between units, and we analyze the mechanisms through which the knowledge broker helps to overcome these limits. We identify three main functions of this knowledge broker that allow the promotion of knowledge and innovation transfer to occur between coopeting units: (1) protecting the unit’s competitive advantage by introducing a lagging principle in the transfer process, (2) reducing sharing costs by standardizing innovative solutions, and (3) enhancing awareness of and trust in innovative solutions by centralizing knowledge diffusion. 相似文献

Students with learning disabilities (LD) consistently struggle with word problem solving in mathematics classes. This difficulty has made curricular, state, and national tests particularly stressful, as word problem solving has become a predominant feature of such student performance assessments. Research suggests that students with LD perform poorly on word problem‐solving items due primarily to deficits in problem representation. Therefore, it is imperative that teachers provide these students with supplemental problem‐solving instruction that specifically targets the development of representational strategies. This article describes how one representational strategy, using number lines, can be used to model word problems as part of a comprehensive problem‐solving intervention to improve the conceptual understanding of math word problems and, subsequently, the problem‐solving performance of students with LD. 相似文献

Understanding students’ conceptions of sustainability 总被引:2,自引:2,他引:0

There has recently been significant emphasis placed on environmental education through, for example, the UN’s Decade of Education for Sustainable Development. Despite this, there is still considerable debate within the literature as to how the aims of environmental education can be achieved within schools. It seems likely that if there is a lack of agreement as to what education for sustainable development should include, then this will impact students’ understanding of sustainable development. This paper presents findings from research investigating how one class of 12‐ to 13‐year‐old geography students in the UK understands the concept of sustainability. The research used concept‐mapping and semi‐structured interviews to explore the students’ understandings of sustainability, within a case study framework. The substantive findings of this research suggest that there is a wide variety of understanding of sustainability among the students, but that generally they allude to three: the nature, purpose and timescale of sustainability. The paper also considers the impact of method on researching students’ subject understandings, in particular the use of context when considering abstract concepts, such as sustainability, and the different results obtained when conducting interviews versus concept maps. 相似文献

Teachers’ responses to inspection were investigated using a questionnaire survey of a random sample of 821 secondary school teachers who had undergone a full OFSTED inspection and in‐depth interviews with a further 35 teachers. The research found that inspection causes additional stress and that female teachers, regardless of level of seniority, felt more nervous about inspection than male teachers. Both male and female teachers felt more nervous when an inspector of a different gender to themselves was observing them in the classroom. Teachers’ affective responses to inspection alter their behavioural ones, thus affecting the resultant picture not only of the school itself but also of schools in this country‐‐a picture on which future advice and policy may be based. Explanations for gender differences are sought using the frameworks of stress and power differentials. 相似文献

Educators and researchers are increasingly interested in the benefits of using Facebook groups attached to university courses, largely around connectedness, engagement and sense of belonging. However, thus far, there have been no broad-scale investigations on the potential outcomes of course-attached Facebook groups. The current study used both within- and between-group analyses on 471 participants, in order to investigate whether courses with an attached official or unofficial Facebook group was related to increased student engagement (in the categories of relationships with faculty members, peer relationships, behavioural engagement, cognitive engagement, valuing and a sense of belonging) and degree identity compared to courses without Facebook groups. Results indicated that students reported interacting more with unofficial than official Facebook groups. Courses with an official Facebook group had significantly greater staff connectedness compared to courses without an official Facebook group, while courses with either an official or unofficial Facebook group had a significantly higher peer relationships compared to courses without any Facebook group. Students with either an official or unofficial Facebook group had a significantly higher sense of belonging. Though students with either an official or unofficial Facebook group reported higher degree identity, this may be primarily due to the unofficial, rather than official Facebook groups; this difference may only exist in the unofficial, but not the official Facebook groups. 相似文献

This paper deals with a semester-long educational experience the authors led at the University of Calabria for reproducing current developments and uncertainties in real-world concurrent engineering, knowledge management practice and virtual enterprise organization. Students with different backgrounds (mechanical engineering, computer science engineering and management engineering) were selected in order to form a laboratory class and then were divided into many multidisciplinary teams. Such teams played different roles and were required to collaborate on the Web to simulate a virtual enterprise, which was aimed at designing virtual prototypes of average complexity articles. In addition to that, any team was involved in the construction of a knowledge base for codifying the explicit knowledge arising from the execution of technical and managerial tasks. The paper deals with models, methodologies and technologies that have been used in this laboratory experience and, moreover, it describes an approach for simulating, in an educational environment, some aspects of the behaviour of virtual enterprises generated by a virtual organization. 相似文献

AbstractThe term ‘feedforward’ is increasingly employed in higher education, and this paper focuses on the way in which it fits into contemporary debates about feedback and its impact on practitioners. Semi-structured interviews were used to investigate the practices academics associate with feedforward and the ways in which their intentions and understandings varied. The term resulted in practices being framed as a process and prompted academics to consider the points in the future when students were expected to deploy information and improve. Three future horizons were identified: the ‘within-module’ future horizon dominated, while the challenges of ‘beyond-module’ and ‘beyond-programme’ horizons became apparent. Written comments, guidance, formative assessment and design practices were associated with feedforward, comprising both transmission and student-focused approaches. It is concluded that the modular system restricts longer-term future horizons and sustainable practices, and more must be done to address the divide between theoretical and practitioners’ perspectives. 相似文献
