This study of 72 undergraduates examined whether theories of learning from text may be extended to hypertext and the effectiveness of hypertext on learning. Participants worked with either a highly structured, unstructured, or linear hypertext system. Results indicated that less structured systems promoted more active processing and a deeper level…

Describes a study that identified various strategies used by graduate students to navigate a hypermedia program about ethnographic research methodology. The strategies included independent interaction, accommodation of a learning partner, cooperation with a partner, collaboration mediated by the program, and reflective collaboration with little or…

Describes three experiments that examined college students' self-determination, problem-solving, and reading comprehension when using a linear, navigational, or generative computerized system to solve a problem or to prepare for a reading-comprehension test. Suggests that understanding students' goals explains outcomes of instruction, effects of…

Describes a study that was conducted to describe and interpret the cognition of a graduate student during information retrieval using the World Wide Web. Results of observation, think aloud protocols, and an in-depth interview are discussed within a theory of information processing, and implications for future research are suggested. (Author/LRW)

Purpose: To outline the conceptual and technical difficulties encountered, as well as the opportunities created, when developing an interlinked collection of web-based digitised primary sources on eighteenth century London. Design/methodology/approach: As a pilot study for a larger project, a variety of primary sources, including the "Old…

The study investigated implications of variations in EAD [Encoded Archival Description]-encoded finding aids on the Web. A content analysis methodology was used to examine five different aspects of EAD finding aids: (1) data elements; (2) labeling terminology; (3) navigation; (4) browsing; (5) searching. Seventeen EAD finding aid web sites…

This article describes the development of the "Electronic Journal Finder," a TDNet installation for the University Libraries of Western Michigan University. Topics covered include: rationale for subscription project timeline, content, product customization, set-up, maintenance issues, reporting functions, directing URL links, searching…

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…

Rodrigo, Chamizo, McLaren, & Mackintosh (1997) demonstrated the blocking effect in a navigational task using a swimming pool: rats initially trained to use three landmarks (ABC) to find an invisible platform learned less about a fourth landmark (X) added later than did rats trained from the outset with these four landmarks (ABCX). The aim of the…

The validity and reliability of a novel route learning test were examined to assess the effectiveness of its use in evaluating spatial memory in healthy older adults and patients with Alzheimer's disease (AD). The Puget Sound Route Learning Test was significantly correlated with an existing measure of cognitive ability, the Dementia Rating Scale.…

High ability, highly verbal fifth grade students (n=12) were studied, by employing think aloud protocols, to identify students' use of learning strategies, encoding processes, and navigational decisions in a hypermedia lesson on propaganda techniques. Subjects were asked to read and think aloud as they worked their way through the concept lesson…

The influences of a student's prior knowledge and desired goal on the difficulties and benefits associated with using hypertext were examined in this study. Participants, 12 students from an undergraduate course in educational psychology, were assigned to either the low or high prior knowledge category. Within these two groups, subjects were…
