Bridge-building activities are practiced widely in the education systems of Europe. They are meant to bridge transitions between lower and upper secondary school and form a mandatory part of the youth guidance system in Denmark. By giving pupils the opportunity to experience the different educational context of upper secondary school, bridge-building activities are meant to facilitate their decision-making on educational paths, but also to attract more and new groups of pupils. However, the premises of the inherent differences of educational contexts and of pupils’ lacking knowledge of upper secondary education can be questioned. In this ethnographic case study of a bridge-building project in a rural area in Denmark, we analyse the implicit knowledge of the general upper secondary school, as it is practiced in a bridge-building project, and how it is experienced by the pupils on the background of their prior knowledge. The analysis is theoretically informed by especially the code concepts of Basil Bernstein. 相似文献

语篇应该具有连贯性,语篇连贯是依靠语篇衔接关系建立起来的。实现语篇连贯的衔接机制有显性和隐性之分,其中显性衔接是实现语篇连贯的主要手段,而隐性衔接则是实现语篇连贯的不可缺少的方式。二者相间使用,相互补充,促成整个语篇连贯的建立。 相似文献

In this article, we explore the meaning potentials of teacher education in terms of the significance of a research-based approach and the different pedagogic identities that such an approach implies. The study’s aim is to examine the important factors for education to be considered research-based and to identify and analyse the research base of teacher education in Sweden. The results from the analysis of a large number of course documents and from a survey administered to teachers and students in four teacher education programmes indicate that the emerging potential meaning is that teacher education is generally a strongly framed professional education with a relatively weak and adapted research base. The analysis of the classification and framing of disciplinary content and pedagogy in the Swedish teacher education curriculum points at different pedagogic identities emerging from the different meaning potentials that are made available to the students. We argue that a thorough understanding of research-based teacher education needs to be grounded in both course content and its research base as well as other possible pedagogical aspects of research-based education; the education as a whole must be included in the concept of research-based education. 相似文献

INTRODUCTION During the development of printing technology, digital printing has played an important role. Now various kinds of multi-color digital inkjet printers are available. Compared with the conventional digital inkjet printer, the multi-color digital inkjet printer has larger color gamut and can faithfully produce more colors. The conventional color printing devices nor- mally use three or four inks, e.g., CMY, CMYK. Although some adopt more than four inks, e.g., CMYKLcLm, the… 相似文献
