Learning from Multimedia and Hypermedia
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by DSpace at Open Universiteit Nederland Chapter 15 Learning from Multimedia and Hypermedia Peter Gerjets and Paul Kirschner Abstract Computer-based multimedia and hypermedia resources (e.g., the world wide web) have become one of the primary sources of academic information for a majority of pupils and students. In line with this expansion in the field of education, the scientific study of learning from multimedia and hypermedia has become a very active field of research. In this chapter we provide a short overview with regard to research on learning with multimedia and hypermedia. In two review sections, we describe the educational benefits of multiple representations and of learner control, as these are the two defining characteristics of hypermedia. In a third review section we describe recent scientific trends in the field of multimedia/hypermedia learning. In all three review sections we will point to relevant European work on multimedia/hypermedia carried out within the last 5 years, and often carried out within the Kaleidoscope Network of Excellence. According to the interdisciplinary nature of the field this work might come not only from psychology, but also from technology or pedagogy. Comparing the different research activities on multimedia and hypermedia that have dominated the international scientific discourse in the last decade reveals some important differences. Most important, a gap seems to exist between researchers mainly interested in a “serious” educational use of multi- media/hypermedia and researchers mainly interested in “serious” experimental re- search on learning with multimedia/hypermedia. -

Extended Link Visualization with DHTML: the Web As an Open Hypermedia System
Extended Link Visualization with DHTML: The Web as an Open Hypermedia System Glenn Oberholzer and Erik Wilde Computer Engineering and Networks Laboratory Swiss Federal Institute of Technology, Z¨urich TIK Report 125 January 2002 Abstract The World Wide Web is by far the most successful hypermedia system, its name often being used synonymously for the Internet. However, it is based on a rather restricted hy- permedia model with limited linking functionality. Even though underlying systems may provide a richer data model, there is still the question of how to present this informa- tion in a Web-based interface in an easily understandable way. Assuming an underlying system similar to Topic Maps, which allows storing, managing, and categorizing meta data and links, we propose a presentation of extended links. We try to provide a usable way for users to handle the additional functionality. The mechanism is based on already available technologies like DHTML. It is one facet of our approach to make the Web more interconnected and to work towards a more richly and openly linked Web. Keywords: Electronic publishing (020), Graphic design (029), Hypermedia (036), Internet (045), World Wide Web (084), XLink, Linkbases, DHTML 1 Introduction Compared to many other hypermedia systems [24,11,16], the linking capabilities of the World Wide Web are rather limited. It only makes use of a few concepts of hypermedia. In recent years, however, new recommendations issued by the W3C like XML [3], XLink [10], and XPointer [9], or ISO/IEC’s Topic Maps [19] have tried to overcome this shortcoming. Due to the popularity of the Web, efforts have to be made to integrate and improve the current system with more sophisticated hypermedia concepts. -

Webvise: Browser and Proxy Support for Open Hypermedia Structuring Mechanisms on the WWW
Webvise: Browser and Proxy Support for Open Hypermedia Structuring Mechanisms on the WWW Kaj Grønbæk, Lennert Sloth, & Peter Ørbæk University of Aarhus Department of Computer Science, Åbogade 34, 8200 Århus N, Denmark. Email: {kgronbak, les, poe}@daimi.au.dk Abstract This paper discusses how to augment the WWW with an open hypermedia service (Webvise) that provides structures such as contexts, links, annotations, and guided tours stored in hypermedia databases external to the Web pages. This includes the ability for users collaboratively to create links from parts of HTML Web pages they do not own and support for creating links to parts of Web pages without writing HTML target tags. The method for locating parts of Web pages can locate parts of pages across frame hierarchies and it is also supports certain repairs of links that breaks due to modified Web pages. Support for providing links to/from parts of non-HTML data, such as sound and movie will be possible via interfaces to plug-ins and Java based media players. The hypermedia structures are stored in a hypermedia database, developed from the Devise Hypermedia framework, and the service is available on the Web via an ordinary URL. The best user interface for creating and manipulating the structures is currently provided for the Microsoft Internet Explorer 4.x browser through COM integration that utilize the Explorers DOM representation of Web-pages. But the structures can also be manipulated and used via special Java applets and a pure proxy server solution is provided for users who only need to browse the structures. -

User Models for Adaptive Hypermedia and Adaptive Educational Systems
1 User Models for Adaptive Hypermedia and Adaptive Educational Systems Peter Brusilovsky1 and Eva Millán2 1School of Information Sciences University of Pittsburgh, Pittsburgh PA 15260, USA 2 ETSI Informática University of Malaga [email protected], [email protected] Abstract. One distinctive feature of any adaptive system is the user model that represents essential information about each user. This chapter complements other chapters of this book in reviewing user models and user modeling approaches applied in adaptive Web systems. The presentation is structured along three dimensions: what is being modeled, how it is modeled, and how the models are maintained. After a broad overview of the nature of the information presented in these various user models, the chapter focuses on two groups of approaches to user model representation and maintenance: the overlay approach to user model representation and the uncertainty-based approach to user modeling. 1.1 Introduction Adaptive hypermedia and other adaptive Web systems (AWS) belong to the class of user- adaptive software systems [174]. One distinctive feature of an adaptive system is a user model. The user model is a representation of information about an individual user that is essential for an adaptive system to provide the adaptation effect, i.e., to behave differently for different users. For example, when the user searches for relevant information, the system can adaptively select and prioritize the most relevant items (see Chapter 6 of this book [125]). When the user navigates from one item to another, the system can manipulate the links (e.g., hide, sort, annotate) to provide adaptive navigation support (see Chapter 8 of this book [21]). -

Integrating Hypermedia Functionality Into Database Applications
Integrating Hypermedia Functionality into Database Applications Anirban Bhaumik*+ Deepti Dixit* Roberto Galnares* Aparna Krishna* Manolis Tzagarakis** [email protected] [email protected] [email protected] [email protected] [email protected] Michalis Vaitis** Michael Bieber* Vincent Oria* Qiang Lu*/*** Firas Alljalad* [email protected] [email protected] [email protected] [email protected] [email protected] Li Zhang* * Collaborative Hypermedia Laboratory, CIS Department, New Jersey Institute of Technology, USA [email protected] ** Computer Technology Institute, University of Patras, Greece *** Suzhou University, Peoples Republic of China +Primary Author Abstract The general goal of our research is to automatically generate links and other hypermedia related services to analytical applications, such as geographic information systems and decision support systems. Using a dynamic hypermedia engine (DHE), we propose to automate the following features for database systems, both on and off the Web. First, we automatically generate links based on the database's relational (conceptual) schema and its original (non-normalized) entity-relationship specification. Second, the application developer can specify which kinds of database elements are related to diverse elements in the same or different database application, or even another software system. Our current DHE prototype illustrates these for a relational database management system. We propose integrating data warehousing applications into the DHE. We also propose incorporating data mining as a new kind of automated link generation. Passing the application element selected by a user, a data mining system would discover interesting relationships for that element. DHE would then map each relationship to a link. DHE’s linking is based on the structure of the application, not keyword search or lexical analysis based on the display values within its screens and documents.
