This paper reports on the results of a survey and qualitative analysis on the teaching of ‘Basic Design’ in schools of design and architecture located in 22 countries. In the context of this research work, Basic Design means the teaching and learning of design fundamentals that may also be commonly referred to as the Principles of Two- and Three-dimensional Design. The body of knowledge associated with Basic Design may be regarded as part of the general theory of teaching and learning design as practiced in many design schools and which has its origins in the classical design schools such as the Bauhaus. In the author’s perception and practice, the pedagogy of Basic Design promotes a holistic, creative and experimental methodology that develops the learning style and cognitive abilities of students with respect to the fundamental principles of design. This includes an understanding of the elements of shape, colour, texture, light, and rhythm in a manner complementary but usually unrelated to the common design methods teaching approach. As is well known among design practitioners, including architects and industrial designers, a deep understanding of the purpose of these fundamental design elements and principles is still relevant to contemporary design practice. The main objective of the research described in this paper was to determine the status and development of Basic Design pedagogy in a significant number of contemporary design schools. On the basis of the results of two surveys conducted in 2001–2002, this paper will identify and illustrate interesting aspects concerning the programmes and organisation of courses delivered by teachers of ‘Basic Design’. This work will also survey the viewpoints of Basic Design teachers in elementary years of design courses and of those teaching design through projects during the subsequent years of the same courses. Interestingly, the design project teachers surveyed in this research expressed a desire to be more involved in the teaching of Basic Design fundamentals which indicates strongly that Basic Design principles are still relevant in contemporary design education terms as they have ever been and that more research is needed in order to better understand and apply the related pedagogy.  相似文献

What happens when educational ideas cross national and cultural borders? How do teachers respond to ideas originating in a different school system and a different national culture? This article reports on an empirical study investigating the transfer of ideas from Design &; Technology as a subject in England and Wales into Norwegian schools. A sample of teachers participating in a specific project on technology teaching inspired by this subject has been studied by means of interviews and classroom observation. Results of the study show that while some elements of Design &; Technology are adopted by the teachers, essential ideas of the subject are significantly transformed. Drawing on Barnes, (1992, Teachers and Teaching: From Classrooms to Reflection (pp. 9–32), The Falmer press, London) concept of teachers' professional frames for teaching, it is shown how specific aspects of the national and educational culture have had a considerable effect on?the teachers' interpretation of the nature of technology as a subject of teaching and its place in the curriculum. The study illustrates the importance of the cultural context in how educational ideas are interpreted, reshaped and realized in schools.  相似文献

The present paper examines the issue of whether interpersonal relationships are critical for global marketing of industrial products. The fields of relationship marketing, IMP group research, sales research, and network theory have stressed the importance of interpersonal relationships in the business-to-business or industrial marketing context. In contrast to this emphasis on interpersonal relationships, we argue that industrial firms can both conceive and enhance marketing strategies based on developing high quality and consistent processes, products, services or outcomes (consistent processes and outcomes). Such strategies are especially important given the fact that developing interpersonal relationships is expensive due to their reliance on frequent and/or face-to-face communications. In this paper, we examine industry and country contexts that lead to the choice of alternative industrial product marketing strategies and highlight some future research directions and managerial implications.  相似文献

2006年石油价格展望   总被引:1,自引:0,他引:1  
本文对影响2006年石油价格的因素做了系统分析。认为2006年形成油价风险的主要动因已从需求的波动转向供给的波动;2006年油价将由于供求的脆弱平衡维持高位运行的格局,并且,由于供给链中潜在的危机,油价波动性将会非常大;但在全球经济增速下降、石油需求增长放缓、石油生产国家和公司仍然在努力满足市场需求、炼油瓶颈有望缓和的大背景下,油价在2006年按2005年可比价格计不会大幅上升,不会对全球经济产生重大负面影响。  相似文献

人是不能离开关系而存活的,从哲学的维度来看,关系就是人的一种生存状态,为人的生存和发展提供了空间和可能。某种程度上说,关系也就是人类社会的代名词,它内涵有社会属性。当然这些关系是在实践中生成的,并且是和实践同构的关系。关系的本质就是一种动态的和谐,而不是一加一的累积。我们可以从社会化的关系、社会关系以及社会内的关系等角度来认识关系。鉴于现在人类面临着越来越多的严峻挑战,旧有的生存关系的“和谐”状态遭到破坏,全面的属人关系产生了一种失衡和异化。在这新的生存环境之中,怎样去建立一种真正的和谐关系,来体察人在现实生活空间中生存和发展的可能性,是值得我们深思的问题。  相似文献
