As intelligent systems demand for human-automation interaction increases, the need for learners' cognitive traits adaptation in adaptive educational hypermedia systems (AEHS) has dramatically increased. AEHS utilize learners' cognitive processes to attain fair human-automation interaction for their adaptive processes. However, obtaining accurate…

This study investigates how graphical and content list type overviews with and without navigation restrictions affect the cognitive load experienced by a learner searching for information in a hypertext. The study used a 2x2 between factor design with the factors navigability (restricted vs. non-restricted) and overview format (graphical vs.…

Introduction: In contemporary information societies, reading digital text has become pervasive. One of the most distinctive features of digital texts is their internal connections via hyperlinks, resulting in non-linear hypertexts. Hypertext structure and previous knowledge affect navigation and comprehension of digital expository texts. From the…

Hypertexts include new structural features, such as navigable graphical overviews, that dramatically change the way students interact with texts. Nevertheless, at school students traditionally practice literacy skills appropriate for reading and comprehending printed texts. We explored the possibility that those skills might not be the same as the…

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 study contributes to research investigating the effects of individual differences and online instructional design on learning. Learning performance was compared across three hypertext formats incorporating different navigational aids. The hierarchical map represented the physical structure of the hypertext in one condition, while the network…

Offers a redefining of three problem areas associated with the cognitive effects of the semiotic characteristics of hypermedia: hypertext associativity, non-linearity, and the rapprochement of real and hypertext navigation. Focuses on navigation and discusses characteristics of hypermedia and its rapport with knowledge. (Author/LRW)

This study examines the cognitive costs of navigation aids in a hypermedia learning task. In a 2(navigable vs. non-navigable) x 2(map vs. content list) experimental design cognitive requirements were measured by users' eye movement data. Additionally, data from users' navigation operations, knowledge acquisition, and subjective evaluation of the…

This study investigates the relationships between undergraduate hypermedia users' information processing styles and navigational patterns. Discusses use of the Human Information Processing Survey, learning styles and information processing styles, and brain hemisphericity. Results show a significant relationship between information processing…

Reviews relevant professional literature concerning hypermedia environments and adaptive instruction for online learning for distance education and continuing education. Highlights include aptitude-treatment interaction; cognitive processes; navigational paths; log files; and intelligent tutors. Contains 125 references. (LRW)

Videotaped observations were made of seventh and eleventh grade students using an instructional hypermedia system. Three profiles of hypermedia navigation emerged with each style characterized by distinct information processing strategies. Analysis of the characteristics of learners revealed that students within each profile group had similar…

This study investigated the relationships between hypermedia users' information processing styles and navigational patterns. Three aspects of navigational patterns were investigated: navigational depth patterns that reveal how comprehensively users access; navigational path patterns that display what sequences users follow; and navigational method…

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…

Describes a study of university students that examined the influences of navigation in hypertext learning environments and discusses advantages and disadvantages of hypertext as instructional media. Discusses active (self-directed) versus passive (pre-sequenced) access; knowledge acquisition; emotional outcomes; and knowledge utilization with a…
