Tag clouds generated in social tagging systems can capture the collective knowledge of communities. Using as a basis spreading activation theories, information foraging theory, and the co-evolution model of cognitive and social systems, we present here a model for an "extended information scent," which proposes that both collective and individual…

This article presents KnowledgePuzzle, a browsing tool for knowledge construction from the web. It aims to adapt the structure of web content to the learner's information needs regardless of how the web content is originally delivered. Learners are provided with a meta-cognitive space (e.g., a concept mapping tool) that enables them to plan…

It is critical that students learn how to retrieve useful information in hypermedia environments, a task that is often especially difficult when it comes to image retrieval, as little text feedback is given that allows them to reformulate keywords they need to use. This situation may make students feel disorientated while attempting image…

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…

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…

Describes a study that explored the use of log files to investigate the process of hypermedia navigation at the University of Connecticut's information kiosk. Highlights include the use of cluster analysis; four different types of navigational performance; and external validation criteria, including self-efficacy, perceived utility, and interest.…

A study of 22 high school students who used a prototype navigational map for browsing hypermedia documents found that the tool was not effective. Supporting previous research the study found the use of maps resulted in poorer performance, less use of the system, lower perceived control, and poorer development of mental representations. (PEN)

A study of 59 undergraduates identified predominant patterns of navigation in studying hypermedia lessons. The study found participants employed an initial systematic, top-down, left-to-right (depth first) strategy to ensure full coverage, then a more spotty and less systematic review. Argues that culture, language, biases, organization of the…

The University of Canberra (Australia) has made courseware on the subject of computer operating systems available on the World Wide Web for a number of years, using a very simple hypertext format. Server logs have previously been analyzed to determine the amount of student usage. This paper reports on a restructuring of the courseware designed to…

This research investigates the ways people learn from multimedia and how navigational patterns can be incorporated into the design structure. The paper begins with a discussion of present navigational research and then presents the results from the initial empirical work, including a pilot study of primary and secondary children using multimedia…
