The paper introduces the highly problematic nature of modelling in design and technology education and examines the relationship between cognitive and concrete modelling. Its aim is to gain insight into what learners do, rather than what others say they ought to do in their learning activities. The variety of purposes that educators have for learners’ modelling are discussed through examining the contested curriculum justification for design and technology education itself. The paper proposes that learners’ modelling cannot be extracted from the social milieu in which they act and it provides some insights of these social influences through the analysis of two case studies. Their settings are a girls’ secondary school and a college of higher education. Each case study is presented independently but organised with a common format to consider a) the impact of assessment on learning intentions and outcomes; b) cultural influences on learning and modelling; c) social influences on learning and modelling. A discussion of the emergent themes considers implications for teachers. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

How does the presence of multinational companies affect plant survival in the host country? We postulate that multinational companies can impact positively on plant survival through technology spillovers. We examine the nature of the effect of multinationals using a Cox proportional hazard model, which we estimate using plant‐level data for Irish manufacturing industries. Our results show that the presence of multinationals has a life‐enhancing effect only on indigenous plants in high‐tech industries, suggesting the presence of technology spillovers. In contrast, multinationals compete with each other in low‐tech sectors in the host country.  相似文献

It appears that programme development in technology education is emerging from an atheoretical perspective. This could be attributed to the absence/neglect of conceptual frameworks (philosophical underpinning) in the development of programmes in technology education. This article explores the role of the content dimension of the 'essential features' of technology and technology education in OBE (Outcomes Based Education) related programme development. An instructional programme was developed using criteria derived from the essential features of technology and technology education. In order to gauge learners' experience, in relation to these essential features, a qualitative case study involving 20 learners was undertaken at a College of Education. Engagement with theprogramme proved to be an empowering experience for the learners who had hitherto not had the opportunity to experience a formal programme in technology education. Although it could not be proved conclusively that cognitive development had occurred, positive inter-dependence,shared responsibility, social skills and enhanced learning were evident. The study has shown that criteria derived from the 'essential features' of technology and technology education could serve as a reliable yardstick to measure the extent of learning in relation to these essential features  相似文献

This study examines the effect of initiating discount and no discount dividend reinvestment plans on shareholder wealth. The results show a negative response to DRP announcements, which is significantly smaller than that found in studies of new equity offerings. These results are consistent with the Scholes and Wolfson (1989) hypothesis that managers in need of equity capital use DRPs to mitigate the adverse stock price effects of new equity issue announcements. Furthermore, there is a significant difference in the price response of discount and no discount DRPs for industrial firms. This result is supportive of the signaling potential of discount DRPs. Supportive evidence is also found in the analysis of firm characteristics for industrial firms.  相似文献
