This study investigated interactive effects of navigation and offline comprehension skill on digital reading performance. As indicators of navigation, relevant page selection and irrelevant page selection were considered. In 533 Spanish high school students aged 11-17 positive effects of offline comprehension skill and relevant page selection on…

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…

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…

The incorporation of various textual resources into scientific inquiry is important for establishing background knowledge. Many of these resources are now presented in hypertext or hypermedia environments, which require students to comprehend and actively integrate information from multiple sources. Further, numerous practices employed by readers…

The present study targeted the online reading strategies of upper-elementary and middle school students with and without learning disabilities in the U.S. and in Taiwan. Several aspects of the comprehension process were studied, including: (1) Internet navigation strategies and behaviours, (2) sensitivity to the organisational structure of…

Deaf users might find it difficult to navigate through websites with textual content which, for many of them, constitutes the written representation of a non-native oral language. With the aim of testing how the information structure could compensate for this difficulty, 27 prelingual deaf users of sign language were asked to search a set of…

Fifty-five undergraduate students read pages on a website presenting text about familiar and unfamiliar geographic locations in the United States. Learners navigated the site by having available or unavailable navigational buttons showing the cardinal compass directions between the map locations in the presence or absence of a cartographic map…

Describes a management system developed by BT Laboratories (United Kingdom) that is based on ISO 9001 using the World Wide Web, a hypermedia system, and part of the Internet. Subject matter is presented as an alphabetical list of linked entries, numerous navigational techniques are available, and searching options function within an index file.…

Discusses problems with navigation in hypertext systems, including cognitive overload, and describes a study that tested information visualization techniques to see which best represented the underlying structure of Web space. Considers the effects of visualization techniques on user performance on information searching tasks and the effects of…

Reviews several mechanisms to support navigation in hypertext following a brief discussion of the phenomena of disorientation in hyperspace. Categorizes ways to support navigation in terms of the following: solutions regarding the tools to support navigation; solutions regarding interface and navigation metaphors; and solutions regarding hardware…

This discussion of hypertext focuses on a study of undergraduates that explored the conditions for making hypertext a better environment than a traditional linear text for studying and for an information search. Highlights include the influence of students' learning styles; and the availability of navigation tools. (Author/LRW)

Describes a study of college freshmen that investigated the effects of navigation maps on search performance, browsing behavior, and cognitive map development within hierarchical-structured hypertext courseware. Results of analysis of variance indicate that map type significantly affected search performance and browsing behavior. (Author/LRW)

Discusses dictionaries in digital form and describes a new type of structured, interactive hyper-dictionary that connects user learning activities with corresponding queries that express information wishes. Topics include dictionaries as knowledge acquisition support tools; searching; browsing; self-assessment though knowledge representation; and…

Outlines important issues to consider when analyzing navigation in hypertext. Identifies internal and external factors of learning and information seeking with hypertext, and presents a summary of related research. Addresses different criteria for analyzing navigation patterns and focuses on the shortcomings of present studies. (AEF)

In the context of exploring educational hypermedia on the World Wide Web, this paper presents a history visualization that helps learners reorganize explored contents to find what Web sites they should visit next. Learning-by-exploration is discussed as it relates to educational hypermedia, including the "Get Lost in Hyperspace" problem,…
