- Abstract
- Elektronische Produktion, Verbreitung und Rezeption von Texten - deren integrative Wechselbeziehungen eingeschlossen - verändern unausweichlich unsere Forschungs-, Lernund Arbeitsbedingungen. In diesem Wandel braucht es Orientierung, Strategien und Kompetenzen. Dieser Band bietet sie in interdisziplinärer Vielfalt. Teil 1 befaßt sich mit Wissen und Wissenschaft. Er spannt den Bogen der Medientheorie von der Antike bis ins 21. Jahrhundert und bietet einen konstruktivistischen Ansatz für das Wissensmanagement. Textsortenkonventionen und Hypertext sind ebenso Schwerpunkte wie empiriegestützte Guidelines und innovative Werkzeuge für das wissenschaftliche Arbeiten. Teil 2 ist Lernumgebungen gewidmet. Reflexionen zur Theorie von hypermedialem Lernen und Kognition werden ergänzt durch ein Produktionssystem für interaktive Software. Eine Felduntersuchungvergleicht Varianten kooperativen Schreibens, ein Schreibdidaktik-Projekt vermittelt zwischen Studium und Beruf. Teil 3 vereint unter dem Titel «Domänen der Praxis» empirische Erhebungen zur Text(re)produktion und elektronischen Kommunikation im Berufsalltag, die Konzeption eines Werkzeugs für die Übersetzungsarbeit und den Ausblick auf kulturspezifische Web-Sites in der Wirtschaft.

- Abstract
- Models administrative and operating costs surrounding a hypermedia database and determines 7 conditions for the cost justification of hypermedia; higher linking costs proportionately reduce the total number of links implemented; increasing the benefits from using the database increases the total number of links proportionately; increasing database size results in an increase in the total number of links implemented; if the database user learns from the database slowly, then a larger number of links need to be provided: the maximum size of databases which is justified on cost will increase as the average cost of linking each node becomes smaller; the total benefit from usage required in order to cost justify a database will decrease as the average cost of linking each node becomes smaller and the maximum size of database which is cost justified will increase rapidly as the learning rate increases. The learning rate can be increased by construction of links and nodes so that they are maximally informative

- Abstract
- Navigating through hyperlinks within a Web site to look for information from one of its Web pages without the support of a site map can be inefficient and ineffective. Although the content of a Web site is usually organized with an inherent structure like a topic hierarchy, which is a directed tree rooted at a Web site's homepage whose vertices and edges correspond to Web pages and hyperlinks, such a topic hierarchy is not always available to the user. In this work, we studied the problem of automatic generation of Web sites' topic hierarchies. We modeled a Web site's link structure as a weighted directed graph and proposed methods for estimating edge weights based on eight types of features and three learning algorithms, namely decision trees, naïve Bayes classifiers, and logistic regression. Three graph algorithms, namely breadth-first search, shortest-path search, and directed minimum-spanning tree, were adapted to generate the topic hierarchy based on the graph model. We have tested the model and algorithms on real Web sites. It is found that the directed minimum-spanning tree algorithm with the decision tree as the weight learning algorithm achieves the highest performance with an average accuracy of 91.9%.

- Abstract
- Experiential learning theory, introduced by Kolb, suggests that people develop different learning styles. A study was conducted to determine whether or not individuals who exhibit certain learning styles are more successful in using a hypermedia problem solving system. The Learning Style Inventory was used to classifiy subjects into 4 groups based on their learning styles: converger, diverger, assimilator, and accomodator. The study found that learning style had an impact on problem solving quality when using the hypermedia system. The preferred learning style in a hypermedia based problem solving environment is the converger. In terms of learning orientation, abstract conceptualizers performed a higher quality of hypertext based problem solving than those who prefer concrete experience

- Abstract
- Hypertext ist ein neuartiges Medium des Lesens und Schreibens, das insbesondere die intensive Integration von Text und Bild ermöglicht. Text erhält einen bildlichen Charakter, und Layout und Graphik vermitteln wesentliche Information. Hypertext ist auch interaktiv und unterstützt autonomes Arbeiten und Lernen. Schreiben von Hypertext unterscheidet sich daher stark vom Schreiben linearer Texte. Diese innovativen Eigenschaften machen es oft schwierig, Hypertext in der universitären Lehre einzusetzen. StudentInnen zögern oft, Hypertext zu verwenden, da sie Probleme mit seiner vernetzten Struktur und seinem «bildlichen» Charakter haben. Die Beobachtung des Einführungsprozesses von Hypertext kann Einsichten darüber vermitteln, wie diese Probleme überwunden werden können.

- Abstract
- There has been an increased growth in the use of hypermedia to deliver learning and teaching material. However, much remains to be learned about how different learners perceive such systems. Therefore, it is essential to build robust learning models to illustrate how hypermedia features are experienced by different learners. Research into individual differences suggests cognitive styles have a significant effect on student learning in hypermedia systems. In particular, Witkin's Field Dependence has been extensively examined in previous studies. This article reviews the published findings from empirical studies of hypermedia learning. Specifically, the review classifies the research into five themes: nonlinear learning, learner control, navigation in hyperspace, matching and mismatching, and learning effectiveness. A learning model, developed from an analysis of findings of the previous studies, is presented. Finally, implications for the design of hypermedia learning systems are discussed

- Abstract
- Hypermedia information systems, because of their inherent qualities of nonlinearity and associative linking, offer the potential of facilitating enhanced knowledge representation and construction for users. These capabilities will be more fully realized if hypermedia information systems are developed and implemented based on constructivist learning theory. Examines the qualities of hypermedia systems that enable them to facilitate learning, discusses the background of current learning theories and provides a brief view of a possible hypermedia system based on constructivist learning principles that could be developed through the use of intellegent autonomous agents

- Abstract
- Reports on a study into the acquisition and transfer of complex knowledge using a conceptually indexed hypertext learning environment based on recent cognitive theory and research. It employed 2 differently structured hypertext thematic criss-crossing (TCC) treatments, Guided TCC and Learner Selected TCC, that demonstrated interrelationships between abstract conceptual and case specific knowledge components in the hypertext materials. Results suggest that students need explicit modelling and scaffolding support in order to learn complex knowledge from a case-based, conceptually indexed hypertext learning environment
