    Abstract
    Die K3-Architektur zur technischen Entwicklung und Realisierung des netzbasierten Wissensmanagement in der Lehre wird dargestellt. Das aktuelle K3-System besteht aus drei zentralen Komponenten; K3Forum (Diskurs), K3Vis (Visualisierung) und K3Wiki (kollaborative Textproduktion, z. B. für Zusammenfassungen). K3 verwendet Open-Source-Software unter der LGPL Lizenz.. Dadurch können freie Verwendung, überschaubare Entwicklungskosten und Nachhaltigkeit garantiert und die Unabhängigkeit von kommerziellen Software-Anbietern gesichert werden. Dank des komponentenbasierten Entwicklungskonzepts kann K3 flexibel und robust laufend weiterentwickelt werden, ohne die Stabilität der bestehenden Funktionalitäten zu beeinträchtigen. Der Artikel dokumentiert exemplarisch die Hauptkomponenten und Funktionen von K3, so dass nachfolgende Entwickler leicht eine Übersicht über das K3-System gewinnen können. Die Anforderungen an den Transfer des Systems in Umgebungen außerhalb von Konstanz werden beschrieben.

    Abstract
    The design and development of web-based educational systems for people with special abilities have recently attracted the attention of the research community. However, although a number of systems that claim to meet accessibility needs and preferences are proposed, most of them are typically supported by hypermedia and multimedia educational content that is specially designed for the user targeted group. Such approaches prevent their user groups (both learners and their tutors) from accessing other available resources. Therefore, it is important to be able to built generic e-learning systems that would allow the reuse of existing learning resources in different accessibility demanding applications. To this end, in this article we propose a methodology for defining an accessibility application profile that captures the accessibility properties of learning objects in a standard form and we examine its application to the IEEE Learning Object Metadata (LOM) standard.

    Abstract
    Purpose - The purpose of this paper is to review recent developments in educational informatics relating to the provision by information systems of pedagogical support to web-based learners, and to propose further investigation of the feasibility and potential value of web-based "conversational" information systems to complement adaptive hypermedia and information retrieval systems. Design/methodology/approach - The potential of Pask's conversation theory is considered as a potentially useful framework for the development of information systems capable of providing pedagogical support for web-based learners, complementary to that provided by existing computer-assisted learning and adaptive hypermedia systems. The potential role and application of entailment meshes are reviewed in relation to other forms of knowledge representation including classifications, semantic networks, ontologies and representations based on knowledge space theory. Findings - Concludes that conversation theory could be a useful framework to support the development of web-based "conversational" information that would complement aspects of computer-assisted learning, adaptive hypermedia and information retrieval systems. The entailment mesh knowledge representation associated with conversation theory provides the potential for providing particularly rich pedagogical support by virtue of its properties of cyclicity, consistency and connectivity, designed to support deep and enduring levels of understanding. Research limitations/implications - Although based on a considerable body of theoretical and empirical work relating to conversation theory, the paper remains speculative in that the gap is still great between, on the one hand, what has so far been achieved and, on the other, the practical realisation of its potential to enhance web-based learning. Much work remains to be done in terms of exploring the extent to which procedures developed and benefits found in relatively small-scale experimental contexts can effectively be scaled to yield enhanced support for "real world" learning-related information behaviour. Originality/value - The ideas of Pask, discussed in this paper, are capable of guiding the structuring of information according to parameters designed to facilitate deep and enduring understanding via interactive "conversational" engagement between the conceptual structures of information source authors and learners. If one can scale Pask's work to "real world" learning-related information behaviour, one can increase the range of web-based information systems and services capable of providing pedagogical support to web-based learners.

    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
    Millions of computer users in the USA have a disability making it difficult to use the Web. The University of Wisconsin System recently required that all System Web pages meet Priority 1 accessibility guidelines as set by the World Wide Web Consortium's Web Accessibility Initiative (W3C/WAI). Class materials available in online learning management systems should also be accessible to students with disabilities. Four systems, Blackboard 4 and 5, Prometheus 3, and WebCT 3, were assessed against theW3C/WAI guidelines for a numerical statistic of accessibility. Practical accessibility was tested with Lynx, IBM Homepage Reader, and JAWS. Validation was performed with A-Prompt and the W3C/WAI checklist.

    Abstract
    Recently, lecture videos have been widely used in e-learning systems. Envisioning intelligent e-learning systems, this article addresses the challenge of information seeking in lecture videos by retrieving relevant video segments based on user queries, through dynamic segmentation of lecture speech text. In the proposed approach, shallow parsing such as part of-speech tagging and noun phrase chunking are used to parse both questions and Automated Speech Recognition (ASR) transcripts. A sliding-window algorithm is proposed to identify the start and ending boundaries of returned segments. Phonetic and partial matching is utilized to correct the errors from automated speech recognition and noun phrase chunking. Furthermore, extra knowledge such as lecture slides is used to facilitate the ASR transcript error correction. The approach also makes use of proximity to approximate the deep parsing and structure match between question and sentences in ASR transcripts. The experimental results showed that both phonetic and partial matching improved the segmentation performance, slides-based ASR transcript correction improves information coverage, and proximity is also effective in improving the overall performance.

    Abstract
    Currently, adaptive educational hypermedia systems (AEHSs) are described using nonuniform methods, depending on the specific view of the system, the application, or other parameters. There is no common language for expressing the functionality of AEHSs, hence these systems are difficult to compare and analyze. In this paper we investigate how a logical description can be employed to characterize adaptive educational hypermedia. We propose a definition of AEHSs based on first-order logic, characterize some AEHSs resulting from this formalism, and discuss the applicability of this approach.

    Abstract
    Wie müssen wir virtuelle Rundgänge und Online-Tutorials gestalten, damit sie ihre Zielgruppe auch wirklich erreichen? Worauf müssen wir bei einer guten Präsentation unseres OPACs achten? Was machen wir mit großen Schülergruppen? Diesen Fragen stellten sich insgesamt 22 Bibliothekarinnen und Bibliothekare in Münster und Köln während zweier Fortbildungsveranstaltungen des HBZ im Juni 2003. Ziel der jeweils zweitägigen Workshops, die in Zusammenarbeit mit der Adhoc-Arbeitsgruppe "Informationskompetenz" der AG der Universitätsbibliotheken im VBNW konzipiert wurden, waren Konzepte und erste Schritte zur Umsetzung von elektronischen Angeboten zur Vermittlung von Bibliotheksbzw. Informationskompetenz. Dem voraus ging die konstruktive Bewertung von bereits existierenden Materialien, die zum einen von den Teilnehmern aus ihren Bibliotheken mitgebracht wurden, zum anderen über Bibliotheks-Homepages abrufbar waren. Die Teilnehmer, die in ihren Bibliotheken bereits Benutzerschulungen konzipieren und durchführen, beschäftigten sich dabei in Gruppen u.a. mit den Themen - Virtuelle Rundgänge, - Online-Tutorials - Bibliothekseinführungen für Schüler und Erstsemester - Präsentationen von Online-Katalog und Methoden zur Literatursuche. Im Folgenden werden einige wesentliche und manchmal durchaus kontrovers diskutierte Ergebnisse und Thesen wiedergegeben, die sich aus der Arbeit der Teilnehmer ergeben haben. Sie erheben keinen Anspruch auf Ausgewogenheit oder Vollständigkeit, können aber als Anregungen und Diskussionsgrundlage für zukünftige Projekte dienen.

    Abstract
    Das Internet entwickelt sich zusehends auch zu einer pädagogischen Lehrund Lernplattform. Durch die vielfältigen Möglichkeiten interaktiver Kommunikation und der Nutzung unterschiedlicher medialer Präsentationsformen eröffnen sich neue Wege der Wissens- und Kompetenzvermittlung. Erfahrungen mit internetbasierten Lehr-/Lernangeboten liegen inzwischen an fast allen deutschen Hochschulen vor. Für Bibliotheken ergeben sich hier neue Möglichkeiten, ihre Schulungsaktivitäten attraktiver und effizienter zu machen. Sie können die an den meisten Hochschulen inzwischen installierten E-Learning-Systeme nutzen, um Veranstaltungen zur Vermittlung von Informationskompetenz anzubieten. Erste Erfahrungen in der Nutzung eines solchen E-Learning-Systems wurden an der Universitätsbibliothek Heidelberg gesammelt.

    Abstract
    To arrive at relevant and reliable conclusions concerning the usability of a hypermedia educational e-book, developers have to apply a well-defined evaluation procedure as well as a set of clear, concrete and measurable quality criteria. Evaluating an educational tool involves not only testing the user interface but also the didactic method, the instructional materials and the interaction mechanisms to prove whether or not they help users reach their goals for learning. This article presents a number of evaluation criteria for hypermedia educational e-books and describes how they are embedded into an evaluation procedure. This work is chiefly aimed at helping education developers evaluate their systems, as well as to provide them with guidance for addressing educational requirements during the design process. In recent years, more and more educational e-books are being created, whether by academics trying to keep pace with the advanced requirements of the virtual university or by publishers seeking to meet the increasing demand for educational resources that can be accessed anywhere and anytime, and that include multimedia information, hypertext links and powerful search and annotating mechanisms. To develop a useful educational e-book many things have to be considered, such as the reading patterns of users, accessibility for different types of users and computer platforms, copyright and legal issues, development of new business models and so on. Addressing usability is very important since e-books are interactive systems and, consequently, have to be designed with the needs of their users in mind. Evaluating usability involves analyzing whether systems are effective, efficient and secure for use; easy to learn and remember; and have a good utility. Any interactive system, as e-books are, has to be assessed to determine if it is really usable as well as useful. Such an evaluation is not only concerned with assessing the user interface but is also aimed at analyzing whether the system can be used in an efficient way to meet the needs of its users - who in the case of educational e-books are learners and teachers. Evaluation provides the opportunity to gather valuable information about design decisions. However, to be successful the evaluation has to be carefully planned and prepared so developers collect appropriate and reliable data from which to draw relevant conclusions.

    Abstract
    Purpose - The CIBER group at University College London are currently evaluating a distance education initiative funded by the Department of Health, providing in-service training to NHS staff via DiTV and satellite to PC systems. This paper aims to provide the context for the project by outlining a short history of distance education, describing the media used in providing remote education, and to review research literature on achievement, attitude, barriers to learning and learner characteristics. Design/methodology/approach - Literature review, with particular, although not exclusive, emphasis on health. Findings - The literature shows little difference in achievement between distance and traditional learners, although using a variety of media, both to deliver pedagogic material and to facilitate communication, does seem to enhance learning. Similarly, attitudinal studies appear to show that the greater number of channels offered, the more positive students are about their experiences. With regard to barriers to completing courses, the main problems appear to be family or work obligations. Research limitations/implications - The research work this review seeks to consider is examining "on-demand" showing of filmed lectures via a DiTV system. The literature on DiTV applications research, however, is dominated by studies of simultaneous viewing by on-site and remote students, rather than "on-demand". Practical implications - Current research being carried out by the authors should enhance the findings accrued by the literature, by exploring the impact of "on-demand" video material, delivered by DiTV - something no previous research appears to have examined. Originality/value - Discusses different electronic systems and their exploitation for distance education, and cross-references these with several aspects evaluated in the literature: achievement, attitude, barriers to take-up or success, to provide a holistic picture hitherto missing from the literature.

    Abstract
    Mit den neuen Medien eröffnen sich auch neue Wege, um Bildung verfügbar zu machen. Das betrifft insbesondere die berufliche Bildung, mit der ein ganz neues Segment auf dem Bildungsmarkt entsteht, aber auch in der Praxis der höheren akademischen Bildung werden die sich neuen Medien zu einschneidenden Veränderungen führen, auf die sich die Lehrer dieser Institutionen einlassen müssen. Es wird sich dabei keinesfalls nur um Verbesserungen oder Verschlechterungen des bestehenden Systems handeln, sondern die Veränderungen werden am Ende ein neues Bildungssystem hervorbringen. Bereits jetzt haben die rasanten Entwicklungen des World Wide Web und der Multimedia-Technologie bewirkt, dass im Bereich der höheren akademischen Bildung Anstrengungen unternommen werden, Lehrinhalte anders als bisher aufzubereiten und den Lernenden auch auf anderen Wegen zur Verfügung zu stellen. Dabei wird bisher hauptsächlich berücksichtigt: (1) Lernen und Lerninhalte müssen flexibler und leichter zugänglich werden, damit daraus dann, wie das Beispiel lebenslangen Lernens zeigt, neue Märkte entstehen können; (2) Multimedia-Werkzeuge sollten die Entwicklung psychomotorischer und intellektueller Fähigkeiten unterstützen, wozu beispielsweise auch Fähigkeiten der Problemlösung und Entscheidungsfindung gehören; (3) Der Einsatz des Internet sollte genutzt werden, um Wissensmanagement und kollaboratives Lernen zu fördern; (4) Das Internet sollte eingesetzt werden, um multikulturelle Kurse und Lernprogramme zu organisieren

    Abstract
    Neue Formen der Aus- und Weiterbildung prägen derzeit die öffentliche und universitäre Diskussion. Im Kontext von Lehren und Lernen mit neuen Medien stellt die Förderung des kollaborativen, selbstgesteuerten Lernens ein zentrales Forschungsgebiet dar [Arnold 2003, S. 16; Mandl 2000, S. 3; Semar 2004a, S. 255]. Dabei hat sich gezeigt, dass eine aktive Förderung und Unterstützung der Systemteilnehmer notwendig ist, in der Regel geschieht dies, indem die einzelnen Akteure dazu aufgefordert werden, meist persönlich durch den Dozenten oder durch ein anderes Gruppenmitglied, bestimmte Tätigkeiten auszuführen. Zwar kann dadurch ein bestimmtes Verhalten in Lernumgebungen "erzwungen" werden, aber besser und erfolgreicher ist es, wenn die Akteure dazu motiviert werden können. Diese Motivation kann mittels entsprechender Anreizsysteme geschehen. Die Problematik liegt jedoch in der Ausgestaltung solcher Anreizsysteme [Schanz 1991, S. 23]. Wir wollen ein "Anreizsystem" darstellen, das aufgrund bestimmter Kennzahlen und deren Visualisierung den einzelnen Akteur so beeinflusst, dass seine intrinsische Motivation gefördert wird und daraus eine eigenständige, aktive Teilnahme am kollaborativen Wissenserarbeitungsprozess resultiert. Ein dem kollaborativen Ansatz angemessenes Anreizsystem mit starker reputativer Ausrichtung soll den gesamten Wissenserarbeitungsprozess unterstützen. Den Akteuren wird eine Aufgabe gestellt, die sie eigenständig als Gruppe lösen sollen. Individuelle Anreize animieren die Akteure bestimmte Leistungen zu erbringen, die dann mit Hilfe des Bewertungssystems bewertet werden. Das Ergebnis wirkt auf die Motivation der Akteure und veranlasst sie weiterhin mitzuarbeiten, bis die gestellte Aufgabe (zufriedenstellend) gelöst wurde. Dieses Anreizsystems ist seit dem Sommersemester 2005 Teil des Software-Systems K3, das in der studentischen Hochschulausbildung kollaboratives und verteiltes Erarbeiten von konzeptuellem Wissen über heterogene Ressourcen und moderierte elektronische Kommunikationsforen ermöglicht.

    Abstract
    The librarians and information specialists play the very important role in the Information Society. They perform a greater variety of tasks than before. That is why the range of knowledge and the skills, they should learn, considerably extends. Therefore the problems arose: how to educate the librarians and information specialists? Which methods and techniques are the most suitable and profitable? How to organize the education process to give them as much experience as possible? The usage of modern methods and tools, especially the e-learning systems, may be the right solution. That paper presents the experiences with the Virtual Learning Environment at Nicolaus Copernicus University. The author is involved in the e-learning process as a teacher of various subjects and as an administrator of Moodie (Modular Object-Oriented Dynamic Learning Environment), which is used as an e-learning platform. The paper describes the process of preparing resources and the methods of using them in education in the field of Information Science and Librarianship. The special attention is paid to knowledge gained and skills trained by students as well as by teachers. Their impressions are shown. The advantages and disadvantages of e-learning are discussed in details.

    Abstract
    Ähnlich spektakulär und informativ präsentieren sich auch die Astronomen: Ihr schier unerschöpflicher Fundus von Bildern und Filmen macht das "elektronische Universum" auf http://zebu.uoregon.edu ebenso einen Klick wert wie die Geschichte von "Geburt und Tod der Sterne" auf demselben Server (http://zebu.uoregon.edu/~js/astl22). Schnell gerät der Wissensdurstige auf reizvolle Seitenpfade, denn viele Vorlesungen glänzen mit sorgfältig zusammengestellten Linklisten. Die führen zum Beispiel zu den "Chemischen Briefen" Justus von Liebigs, wie sie im 19. Jahrhundert zunächst als Wissenschaftskolumne in der Augsburger Allgemeinen Zeitung erschienen (www.liebig-museum.de/chbriefe/homepage.htm). Selbst die Alchemie - neunzig ansprechend präsentierte Megabyte auf www.alchemywebsite. com - verleitet zum Verweilen. Historisches ist, weil nicht stets aktualisierungsbedürftig, ohnehin beliebt im Netz. So wartet etwa die Universität Groningen (Niederlande) mit einem voluminösen Hypertext auf, praktisch ein komplettes Lehrbuch der amerikanischen Geschichte mit Texten, Essays und Präsidentenbiografien (http://odur.let.rug.nl/usanew). Noch weiter zurück in die Vergangenheit reicht eine Anthropologen-Website über den Ursprung des Menschen (www.geocities.com/Athens/Acropolis/5579/TA.html). Verspieltere Naturen werden dort zuerst fossile Schädel zuzuordnen versuchen ("Name That Skull") oder einem Anthropologiestudenten beim Wurf des Atlatl zusehen. Dieser frühe Wurfspeer machte schon den Mammuts zu schaffen und drang noch vor wenigen hundert Jahren durch die eiserne Rüstung spanischer Konquistadoren. Selbst Angewandtes bietet die World Lecture Hall. Etwa die "Geschichte der ökonomischen Denkweise" einschließlich eines 22-Minuten-"Interviews" mit Karl Marx auf www.boisestate.edu/econ/lreynol/web/het.htm. Oder Online-Sprachkurse: Wollof und Xhosa, Suaheli und Sanskrit lehrt http://www.word2word.vorn/courscad.html. Surfen allein fördert die akademische Karriere allerdings nicht unbedingt. Wer of fizielle Online-Zertifikate in Deutschland anstrebt, findet in dem Beitrag "Virtuelle Universität im Selbstversuch" (Spektrum der Wissenschaft 11/ 2001, S. 109) gute Startpunkte für das Studieren im Netz, angefangen bei - na wo wohl? - www.studieren-irre-netz.de."
