Learning style and learning strategies in a multimedia environment
There is a growing realization that it may be expeditious to combine elements from different theories of learning when trying to derive a coherent and usable policy towards computerāmediated learning. Consideration of the subtle distinction between ComputerāAided Learning (CAL) and ComputerāAided Instruction (CAI) conform the basis of a possible classification of computerāmediated learning, and hence of multimedia tools. This classification enables the development of a continuum upon which to place various strategies for computerāmediated learning, and hence a means of broadly classifying multimedia learning tools

Semi-automated creation of converged iTV services: From macromedia director simulations to services ready for broadcast
While sound and video may capture viewersā attention, interaction can captivate them. This has not been available prior to the advent of Digital Television. In fact, what lies at the heart of the Digital Television revolution
is this new type of interactive content, offered
in the form of interactive Television (iTV) services. On top of that, the new world of converged networks has created a demand for a new type of converged services on a range of mobile terminals (Tablet PCs, PDAs and mobile phones). This paper aims at presenting a new approach to service creation that allows for the semi-automatic translation of simulations and rapid prototypes created in the accessible desktop
multimedia authoring package Macromedia Director
into services ready for broadcast. This is achieved by a series of tools that de-skill and speed-up the process of creating digital TV user interfaces (UI) and applications for mobile terminals.
The benefits of rapid prototyping are essential for the production of these new types of services, and are therefore discussed in the first section of this paper.
In the following sections, an overview of the
operation of content, service, creation and management sub-systems is presented, which illustrates why these tools compose an important and integral part of a system responsible of creating, delivering and managing converged broadcast and telecommunications services.
The next section examines a number of metadata
languages candidates for describing the iTV services user interface and the schema language adopted in this project. A detailed description of the operation of the two tools is provided to offer an insight of how they can be used to de-skill and speed-up the process of creating digital TV user interfaces and applications for mobile terminals. Finally, representative broadcast oriented and telecommunication oriented converged service components are also introduced, demonstrating how these tools have been used to generate different types of services
KnowledgePro windows: The order of merit?
The producers of KnowledgePro look set with their latest release of KPWIN (KnowledgePro Windows) to fulfil Richard HaleāShaw's prophecy that it will become āone of the most powerful visual development environmentsā (HaleāShaw 1992). Comparisons are drawn in this paper between the KPWIN family of products and other authoring tools. The conclusion is that KPWIN is worthy of being included in any courseware developer's tool set. Reasons for preferring a tool from the KnowledgePro family of products for courseware development over three main competitors ā Authorware, Toolbook and Visual Basic ā are explained, and the merits of KPWIN and KPWIN++ (a version that generates C++ code) are examined
Performance of voice and video conferencing over ATM and gigabit ethernet backbone networks
Gigabit Ethernet and ATM network technologies have been modeled as campus network
backbones for the simulation-based comparison of their performance. Real-time voice and
video conferencing traffic is used to compare the performance of both backbone
technologies in terms of response times and packet end-to-end delays. Simulation results
show that Gigabit Ethernet has been able to perform the same and in some cases better than
ATM as a backbone network for video and voice conferencing providing network designers
with a cheaper solution to meet the growing needs of bandwidth-hungry applications in a
campus environment
