Gestaltungsmerkmale und Effekte ganztägiger Angebote im Grundschulbereich

Zusammenfassung Ganzt?gige schulische Angebote spielen in der aktuellen Debatte um eine Bildungsreform eine zentrale Rolle. Erwartungen an ihre erzieherischen und leistungsbezogenen Wirkungen werden hier zun?chst theoretisch auf dem Hintergrund der Schuleffektivit?tsforschung diskutiert. Empirisch werden — erstmals repr?sentativ für Deutschland — p?dagogische Angebote und Schülerleistungen an Grundschulen mit und ohne Ganztagsangebot verglichen. Basis ist eine Sekund?ranalyse von Daten der internationalen Grundschul-Leseuntersuchung IGLU in Verbindung mit einer nachtr?glichen Schulleiterbefragung. Schulen mit ganzt?gigen Angeboten verfügten demnach über ein breites Spektrum von p?dagogischen Ma?nahmen, wobei in Ganztagsschulen mit systematischem Konzept die kognitive F?rderung relativ stark gewichtet war. Effekte auf das Niveau des Leseverst?ndnisses oder dessen Zusammenhang mit der sozialen Herkunft fanden sich nicht.      

Dynamic Management of Digital Rights for Long-term Preservation:the Expert System Approach

This presentation focuses on the complex issue of managing digital rights for long-term preservation. It describes the strategy and the methodology adopted within the SPAR project (French National Library), which rely on a special kind of knowledge-based system.     

Anticipating Ethical Challenges: Is There a Coming Era of Nanotechnology?

In this paper I question the claims made for a ‘coming era of nanotechnology’ and the ethical challenges, it is argued, that are entailed by this particular technological revolution. I argue that such futurist claims are sustained by an untenable modernist narrative which separates the technical and the social. This is exemplified by the work of K. Eric Drexler and his claim that whilst the course of scientific knowledge may remain unpredictable we nevertheless can predict with accuracy the trajectory of technology and particularly the emergence of nanotechnology. The problem then, on the basis of knowledge about the future state of technology, is to make choices now which will forestall unintended and undesirable consequences. Firstly, the paper argues for a radical scepticism towards all forms of forecasting or prediction but especially technological forecasting of the type exemplified in the debate around nanotechnology. Secondly, given this radical scepticism the paper criticises the idea that a prospective ethics can be created on the basis of an assessment of consequences of nanotechnology.     

Vowel perception and production in adolescents with reading disabilities

Perception and production of the vowels /I/, /?/, /æ/ in the words pit, pet and pat were investigated in two groups of adolescents who differed significantly on measures of reading and phonological awareness. Perception performance was assessed using slope measurements between vowel categories. Duration measurements and a rating system based on first and second formant (F1 and F2) values were used to analyze production performance. As a group, the students with reading disabilities not only perceived but also produced less well-defined vowel categories than the control group of age-matched good readers. Perception and production performance, however, were not correlated. Results suggest that the speech processing difficulties of the students with reading disabilities include weak phonological coding for vowel sounds with similar phonetic characteristics. The implications of these findings for intervention are addressed.     

How organisations evaluate their knowledge management projects: a meta-study of the period 1992–2002

The key objective of this research was to develop an understanding of what organisations are measuring within the context of knowledge management (KM) evaluation. A comprehensive meta-analysis of international articles dealing with the evaluation of KM, Intellectual Capital and other closely related domains between the years 1992 and 2002 was undertaken. A total of 1539 articles reflected the search topic. A manual review of all abstracts resulted in a narrowed selection of 223 articles, sourced from 126 different journals. Data for 1992–1995 were rejected due to insufficient occurrences of empirical measurement. Content analysis with the use of the NUD^*IST^® software of the data resulted in 12 evaluation factors being identified. Four factors made up 72% of the study's findings: human capital, financial, process and customer. However, by charting the number of measures within each factor against each year from 1996 to 2002, some identifiable trends were highlighted. Financial, human capital, internal infrastructure and composite measures, such as the Balanced Scorecard, have grown in varying degrees in frequency of use, while customer, process, intellectual property, innovation and quality-related measures have gradually lost ground.     

Chasing Heideggerian circles: Freedom,call, and our educational ground

Over the last couple of decades, Heideggerian philosophy has become an important resource for educationalists. A growing body of literature has demonstrated its educational potential, thus illumining pivotal educational features and phenomena. Whereas my research is situated in the critical space opened by this literature, I adopt a slightly different perspective: in this paper, I discuss what we may refer to as the thoroughly educational nature of Heideggerian philosophy. I contend that Heideggerian thought is not only anchored by questions and features that are quintessentially pedagogical but also represents a passionate and ethical call to freedom, becoming and the space of the ‘not-yet’, a call that appeals to the self to overturn his gesture and position; a call that is, in and of itself, educational. Rather than abandoning the initiative towards Being, Heidegger, in the late 1920s, created an ethic of resoluteness and choice that places freedom and responsibility centre stage. Hence, when analysing Heidegger’s thought, we need not necessarily place educational concerns and demands from without, nor must we necessarily apply Heideggerian insights to analyse educational features and phenomena, for Heideggerian philosophy is always already rooted in, and in a sense is, an educational endeavour.     

Integrated use of technologies and techniques for construction knowledge management

The last two decades have witnessed a significant increase in discussions about the different dimensions of knowledge and knowledge management (KM). This is especially true in the construction context. Many factors have contributed to this growing interest including globalisation, increased competition, diffusion of new ICTs (information and communication technologies) and new procurement routes, among others. There are a range of techniques and technologies that can be used for KM in construction organisations. The use of techniques for KM is not new, but many technologies for KM are fairly new and still evolving. This paper begins with a review of different KM techniques and technologies and then reports the findings of case studies of selected U.K. construction organisations, carried out with the aim of establishing what tools are currently being used in U.K. construction organisations to support knowledge processes. Case study findings indicate that most organisations do not adopt a structured approach for selecting KM technologies and techniques. The use of KM techniques is more evident compared to KM technologies. There is also reluctance among construction companies to invest in highly specialised KM technologies. The high costs of specialist KM technologies are viewed as the barrier to their adoption. In conclusion, the paper advocates integrated use of KM techniques and technologies in construction organisations.     

Academic self-concept,autonomous academic motivation,and academic achievement: Mediating and additive effects

Three conceptual models were tested to examine the relationships among academic self-concept, autonomous academic motivation, and academic achievement. This allowed us to determine whether 1) autonomous academic motivation mediates the relation between academic self-concept and achievement, 2) academic self-concept mediates the relation between autonomous academic motivation and achievement, or 3) both motivational constructs have an additive effect on academic achievement. A total of 925 high school students (404 boys and 521 girls) were asked to complete a questionnaire on two occasions separated by a year interval. Results from SEM analyses provided good support for the hypothesized model positing that autonomous academic motivation mediates the academic self-concept–academic achievement relation. Results are discussed in light of self-determination theory and self-concept theory.     

Was verbinden Museumsbesucher mit Lernen im Museum und in der Schule?

The present study was conducted in the Deutsches Museum in Munich, the Senckenberg Museum in Frankfurt am Main and the Landesmuseum Schloß Gottorf in Schleswig. 160 museum visitors were asked about their conceptions of learning in school and learning in a museum. These conceptions generate a persons’ individual concept of learning. It is formed by the influence of the subjectively different experiences each person makes in varying learning situations. Since every learning environment offers different opportunities and possibilities for learning, it can be assumed that there are location-specific concepts of learning. The results of this study show that concepts of learning in school can be differentiated from concepts in a museum; albeit reactive and constructive concepts of learning were found for schools as well as for museums. In addition it was found that different people’s concepts of learning depend on their places of learning.     

Disciplinary Networks and Bounding: Scientific Communication Between Science and Technology Studies and the History of Science

This article examines the communication networks within and between science and technology studies (STS) and the history of science. In particular, journal relatedness data are used to analyze some of the structural features of their disciplinary identities and relationships. The results first show that, although the history of science is more than half a century older than STS, the size of the STS network is more than twice that of the history of science network. Further, while a majority of the journals in the STS network are connected by weak ties, about half of the history of science network consists of strong ties. The history of science network is thus more cohesive than the STS network. The relatively strong cohesion within the history of science network is associated with comparatively high degrees of intra-disciplinary communication, but comparatively weak ties to only a few related disciplines. The analysis also shows that very few members of the history of science cliques are situated on the shortest path between both specialties. Moreover, given the relatively impermeable nature of the history of science network, the latter partially depends on STS to reach some of the neighboring disciplines.
