In many engineering curricula a period of practical training in industry is either compulsory or advised. Often the educational goals of such a period are defined as 'learning to put knowledge and skills into practice'. The assessment is usually based on a technical report of the activities during the period. In this paper, how the definition of educational objectives led to the introduction of practical training is discussed. These objectives are acquiring insight in the engineering profession, learning to 'survive' in a different culture and learning to apply as well as broadening technical knowledge and skills. Furthermore, an assessment procedure is introduced which allows for testing whether the students have met the objectives.  相似文献

One of the most salient arguments in favor of a semiotic approach, put forward on various occasions among others by Luis Radford, claims that semiotics is most appropriate to treat the interaction between socio-cultural and objective aspects of knowledge problems. But if we want to take such claims seriously, we have to undertake revisions of our basic conceptions about reality, existence, cognition, and cultural development. The semiotic evolutionary realism of Charles S. Peirce provides, or so it appears, an appropriate basis to such intentions. Man is a sign, Peirce had famously said, and ??thought is more without us than within. It is we that are in it, rather than it in any of us?? (Peirce CP 8.256). And as there is no thought without a sign, we have to accept thoughts, concepts, theories, or works of art as realities sui generis. Concepts or theories have to be recognized as real before we can ask for their meaning or relevance. This was the problem that concerned critics and protagonists of the New Math Reform of the 1960s and 1970s of the twentieth century, like Thom or Bruner.  相似文献

Legal provisions, cross-company data exchange and intra-company reporting or planning procedures require comprehensively, timely, unambiguously and understandably specified business objects (e.g. materials, customers, and suppliers). On the one hand, this business metadata has to cover miscellaneous regional peculiarities in order to enable business activities anywhere in the world. On the other hand, data structures need to be standardized throughout the entire company in order to be able to perform global spend analysis, for example. In addition, business objects should adapt to new market conditions or regulatory requirements as quickly and consistently as possible. Centrally organized corporate metadata managers (e.g. within a central IT department) are hardly able to meet all these demands. They should be supported by key users from several business divisions and regions, who contribute expert knowledge. However, despite the advantages regarding high metadata quality on a corporate level, a collaborative metadata management approach of this kind has to ensure low effort for knowledge contributors as in most cases these regional or divisional experts do not benefit from metadata quality themselves. Therefore, the paper at hand identifies requirements to be met by a business metadata repository, which is a tool that can effectively support collaborative management of business metadata. In addition, the paper presents the results of an evaluation of these requirements with business experts from various companies and of scenario tests with a wiki-based prototype at the company Bayer CropScience AG. The evaluation shows two things: First, collaboration is a success factor when it comes to establishing effective business metadata management and integrating metadata with enterprise systems, and second, semantic wikis are well suited to realizing business metadata repositories.  相似文献

Against the backdrop of the recent political discourse on elite and excellence in the German education system, this paper examines how such constructions manifest themselves in programmatic concepts of schools and in the orientations of their pupils and their peers. They are reconstructed on the basis of a qualitative research project on educational careers of young people. This paper focuses on pupils and their peers at an elite school of sports and an international school. Firstly, the state of research on those types of school as well as on educational careers of their pupils will be presented. Secondly, the theoretical reference points and the methodological design of the study will be introduced. At the core of the paper is the analysis of the education related orientations of selected cases of young people and their peers: How do they position themselves towards elite and excellence in their individual and collective orientations and how is this relevant for processes of distinction and coherence building in the groups? In the resuming part of the paper, the results will be summarised and related to the state of research and the scientific discourse on elite and excellence.  相似文献

The unification of the two German states in October 1990 had a significant impact on educational politics. The combination of two educational and university systems that were based on clearly divergent political and social foundations lay ahead. The thesis is discussed here that the unification of FRG and GDR could not lead to the renewal of universities in Germany but only to an adaptation of eastern society to western society. But with the foundation of a Faculty of Educational Sciences at the Technical University of Dresden (Land Saxony) successful attempts to renewals at an intermediate level are also presented. The author describes the production and realization of a project he helped to develop and at the same time addresses the emerging problems the new faculty triggered.  相似文献

This paper describes the use of a three-circle Venn diagram as a vehicle for introducing pre-service elementary teachers to pedagogical content knowledge (PCK). Each circle of the diagram represents pedagogy, content and context individually. The overlap of any two circles represents the interaction between the circles. For example, the overlap of pedagogy and context relates to the ways that each of these general topics influences the other. The overlap of all three circles represents a complete lesson that is an integration of the three major components of PCK. The Venn diagram is an easily remembered graphic illustration of PCK that can be useful in planning lessons. The use of this graphic organizer in a science capstone course required of all pre-service elementary teachers is described.  相似文献

This paper gives a concise historical account of government policy in the development of nuclear power reactors in West Germany. In addition to published sources, information is drawn from the minutes of government advisory bodies and from interviews with individuals involved in policymaking. It is found that the decentralization of decision-making was a key factor in the relative success of the West German reactor programme. Government support was given in a way that left the essential technical and commercial decisions with manufacturers and utilities. The development work for the eventual successful light-water reactor was a largely self-financed effort of firms commanding a strong technical and commercial tradition in power plant construction. The utilities based their decisions on the basis of internationally available technology independent of, and initially even against, the programmes devised by the government. In the period up to the year 1972, less than ten percent of government expenditure for reactor development was spent on types that are now in commercial use, i.e. on light-water reactors, while the bulk was given to reactor types that have a chance for commercial application only in the longer term, such as the high-temperature gas-cooled reactor and the fast breeder reactor.  相似文献
