- 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
- Organizations are fielding increasingly complex systems for use ny knowledge workers at all levels. This often results in situations where the operators' skills, knowledge, and abilities are not sufficient to ensure efficient, accurate performance. Often, the solution has been the development of online help, Computer Based Training, or job aids. However, none of these alone provides the full support that the integration of AI technologies, hypermedia, and CBT could offer. Introduces the concept of Performance Support Systems, whose components include embedded training, hypermedia help, AI-based coaches, and an adaptable model-based user interface. Explores the concept through a discussion of the design of a PSS for a complex database system

- 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.

- 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
- Presents a pragmatic cognitive theory of instruction, the CLAI model (Cognitive Learning from Automated Instruction), which is intended to be a theory practically useful for developing real instructional systems. Defines learning from a cognitive perspective as well as a generation view of learning from instruction, and in particular from automatic instruction. Sets out different instructional theories relating cognitive processes and instructional events, and the CLAI model of instruction for intelligent tutoring systems (ITS). Illustrates a practical approach for ITS development and gives an example of integration of the model inside an automated tutor architecture

- 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.
