The article starts with some basic considerations of crucial trends such as the expansion of new technologies and media, demographic changes, economic crises, changes in the relation between the sexes and the emergence of multicultural societies.The following two sections deal with the global dimensions in socio-economic change and the tension between universality and diversity in education. They also consider the relation between schools and their competitors in the area of nonformal education, such as youth movements, sports clubs, etc.Following this, some essential expectations in relation to the changing role of schools from governmental institutions to service agencies are analyzed; other aspects treated include the demands on participation at the grassroots level, knowledge transmission with regard to practical utilization, the growing interest in vocational education and the wide-spread divergencies in moral standards within societies.The conclusion to the article concentrates on the postulate that schools must define their existence and legitimacy by finding an equilibrium between adjustment (in terms of modernization) and conservation (in terms of maintaining continuity).
Zusammenfassung Im ersten Teil des Artikels stellt der Verfasser grundlegende Betrachtungen an über wichtige Entwicklungsströmungen wie z.B. über die Ausweitung neuer Technologien und Medien, demographische Veränderungen, Wirtschaftskrisen, Wandlungen in den Beziehungen zwischen den Geschlechtern und die Entstehung multikultureller Gesellschaften.Die beiden nächsten Abschnitte handeln von den globalen Dimensionen des sozioökonomischen Wandels sowie von der Spannung zwischen der Universalisierung und der Diversifizierung des Erziehungswesens. Ferner werden die Beziehungen zwischen den Schulen und den mit ihnen konkurrierenden Einrichtungen im Bereich der nicht-formalen Erziehung wie z.B. Jugendbewegungen, Sportvereinen usw. erörtert.Darüber hinaus werden wesentliche Erwartungen analysiert in Hinblick auf die sich ändernde Rolle der Schulen von Regierungseinrichtungen zu Dienstleistungsagenturen. Die Forderung nach Beteiligung auf der Basisebene sowie die Vermittlung von praxis-orientierten Kenntnissen, das wachsende Interesse an beruflicher Bildung und die weitverbreiteten Divergenzen moralischer Richtlinien innerhalb verschiedener Gesellschaften, werden im Hauptteil des Aufsatzes besprochen.Der Artikel schließt mit dem Postulat, daß Schulen zu einer Definition ihrer Existenz und ihrer Legitimität gelangen müssen, indem sie das Gleichgewicht herstellen zwischen Anpassung (im Sinne von Modernisation) einerseits und Erhaltung (im Sinne von Kontinuität) andererseits.

Résumé Cet article présente tout d'abord quelques considérations fondamentales sur les tendances cruciales telles l'expansion des nouvelles technologies et des media, l'évolution démographique, les crises économiques, les changements qui apparaissent dans les rapports entre les deux sexes, l'émergence de sociétés multiculturelles.Les deux parties qui suivent traitent les dimensions globales du changement socioéconomique et examinent les tensions entre l'universalité et la diversité de l'éducation. Elles examinent également la relation entre les écoles et leurs concurrents dans le domaine de l'éducation non-formelle, tels les mouvements de jeunes, les associations sportives, etc.Ensuite l'auteur analyse quelques-unes des exigences essentielles relatives au rôle variable des écoles comme institutions gouvernementales se mouvant en organismes de service; les autres aspects traités incluent les demandes de participation au niveau de la base, le transfert des connaissances en ce qui concerne l'utilisation pratique, l'intérêt sans cesse croissant pour l'enseignement professionnel et les normes de plus en plus divergentes concernant les valeurs morales au sein des sociétés.La conclusion de cet article met un accent sur le postulat selon lequel les écoles doivent définir leur existence et leur légitimité en trouvant un équilibre entre adaptation (en termes de modernisation) et conservation (en termes de maintien de la continuité).

This article investigates whether different formats of visualizing information result in different mental models constructed in learning from pictures, whether the different mental models lead to different patterns of performance in subsequently presented tasks, and how these visualization effects can be modified by further external representations during task performance. A total of 80 university students learned from an illustrated text different day times and different dates exist simultaneously on the earth. One half of the participants received the text combined with pictures visualizing the earth as a kind of carpet (carpet pictures), whereas the other half received the text combined with pictures visualizing the earth surface as a circle (circle pictures). After learning, the participants received a test including different kinds of tasks. In both visualization groups, one half of the participants solved the tasks with an additional external representation, whereas the other half solved the tasks without an external representation. The findings indicate that the form of visualization affects the structure of mental models. Different structures of mental models result in different patterns of performance, when individuals solve tasks based only on their mental representations acquired during their previous learning. However, these effects decrease, when further external representations are made available to the learners. The findings are discussed within a broader framework of learning with multiple external representations.  相似文献

After many years of neglect, the subject of giftedeness as a topic of research has once again received more attention in German speaking countries since the end of the 1970s. The somewhat hesitant, systematic study of highly gifted children and adolescents, especially the question of how to identify and encourage them, was accompanied over the years by controversial and exhaustive educational policy debates. Emphasis on aspects such as equality of opportunity and elitist education has, inter alia, contributed considerably to the fact that the interests of gifted children–even if discussions have aroused increasing public interest, i.e. discussion of giftedness has became socially acceptable — have only slowly begun to be emphasized. It is probably for this reason that little attention has been paid to grade skipping. The students in the present study who skipped a grade coped as a group quite well with work in the higher grade, depite a low level of support from the schools.  相似文献

Basic theoretical approaches in the history of text comprehension research have been reviewed and compared to their instructional implications: readability research, comprehensibility research, traditional psycholinguistics, traditional elementaristic models of text processing, and new holistic models of text processing. Contrary to a sceptical view, which denies the practical instructional relevance of text comprehension research, recommendations for instructional design can be shown to be closely related to specific theoretical perspectives. Especially in the last years important advances in research have taken place which have considerably changed our picture of text comprehension. The more refined understanding of text processing implies more differentiated and specific recommendations for instructional design, which go far beyond everyday knowledge about text comprehension. This is illustrated on the basis of new holistic theoretical approaches combined with the notion of procedural semantics. The instructional value of the new theories on text processing is seen in their heuristic function. They provide new perspectives on instructional problems and suggest new ways of thinking. Thus, they are a basis for attaining a more comprehensive and differentiated analysis and, thus, for better founded instructional decisions.  相似文献

Towards mapping library and information science   总被引:3,自引:1,他引:3  
In an earlier study by the authors, full-text analysis and traditional bibliometric methods were combined to map research papers published in the journal Scientometrics. The main objective was to develop appropriate techniques of full-text analysis and to improve the efficiency of the individual methods in the mapping of science. The number of papers was, however, rather limited. In the present study, we extend the quantitative linguistic part of the previous studies to a set of five journals representing the field of Library and Information Science (LIS). Almost 1000 articles and notes published in the period 2002–2004 have been selected for this exercise. The optimum solution for clustering LIS is found for six clusters. The combination of different mapping techniques, applied to the full text of scientific publications, results in a characteristic tripod pattern. Besides two clusters in bibliometrics, one cluster in information retrieval and one containing general issues, webometrics and patent studies are identified as small but emerging clusters within LIS. The study is concluded with the analysis of cluster representations by the selected journals.  相似文献
