This study focuses on carrying out weighted digraph-based mathematical construction of hypermedia and user navigation on hypermedia and making a presentation of "weighted" forms of known stratum and compactness. In the instructional Web design researches, the structural analysis of navigation on the hypermedia is important in modeling the…

Typical web lectures consist of two different kinds of media linked together: an audio- or video-recording and the corresponding slides or desktop recording. Both media are synchronized so that the slide or image shown corresponds to the position currently played in the time-based media stream. Web lectures are thus composite media consisting of a…

This article describes how the author applied principles of universal design to hybrid course materials to increase student understanding and, ultimately, success. Pulling the three principles of universal design--consistency, color, and icon representation--into the author's Blackboard course allowed her to change the types of reading skills…

Purpose: The purpose of this paper is to propose an indexing and teaching focus mining system for lecture videos recorded in an unconstrained environment. Design/methodology/approach: By applying the proposed algorithms in this paper, the slide structure can be reconstructed by extracting slide images from the video. Instead of applying…

Interactive learning environments (ILEs) are increasingly used to support and enhance instruction and learning experiences. ILEs maintain and display information, allowing learners to interact with this information. One important method of interacting with information is navigation. Often, learners are required to navigate through the information…

Purpose: Social navigation is an emerging trend for navigation in hypermedia. With social navigation, users can be guided through large volumes of learning content by cues which integrate the browsing history of past users. Earlier papers have shown that social navigation is suitable for navigation not only in classic hypermedia but also in…

This paper reports on the design strategies and technical solutions that the authors have adopted to increase interaction in a World Wide Web-Based Instruction (WBI) system aimed at supporting new didactic approaches to the subjects of urban planning and architecture through the activation of online modules at the university level. Specifically,…

Educational Adaptive Hypermedia Applications (EAHA) provide personalized views on the learning content to individual learners. They also offer adaptive sequencing (navigation) over the learning content based on rules that stem from the user model requirements and the instructional strategies. EAHA are gaining the focus of the research community as…

Modeling the functions of a teacher in a computer interface is not a new practice; most computer applications employ electronic performance support systems (EPSS) such as online help, wizards, coaches, and even some forms of artificial intelligence. This paper presents easy-to-implement strategies for increasing learner autonomy by embedding…

The role of conceptual modeling in Educational Adaptive Hypermedia Applications (EAHA) is especially important. A conceptual model of an educational application depicts the instructional solution that is implemented, containing information about concepts that must be ac-quired by learners, tasks in which learners must be involved and resources…
