The aim of this research is to introduce a method of constructing knowledge structures which represent the relationships among the knowledge items in a pedagogically useful way. A prototype, "MyTeLeMap," was implemented to support both learners and instructors. Learners could visualize the knowledge structures of different knowledge…

The interoperability of educational systems, encouraged by the development of specifications, standards and tools related to the Semantic Web is limited to the exchange of information in domain and student models. High system interoperability requires that a common framework be defined that represents the functional essence of educational systems.…

Traditional hypermedia applications present the same content and provide identical navigational support to all users. Adaptive Hypermedia Systems (AHS) make it possible to construct personalized presentations to each user, according to preferences and needs identified. We present in this paper an alternative approach to educational AHS where a…

In this work is proposed that an adaptation tool that is for the automatic generation and personalization of courses of a general-purpose LCMS that is named A Tutor. A Tutor is a Learning Content Management System. The architecture of the adaptation tool that allows a personalized sequencing of LOs in A Tutor for the learner's learning goals,…

What kind of influence does the structure of an educational hypermedia system have on the way its users understand its contents and organize the knowledge they acquire through its browsing? In this article, this already much discussed question, situated at the boundary between semiotics and cognitive science, is revisited in the light of results…

The current historical moment is marked by the gradual transition from a print culture to a digital new media culture, and this shift carries material effects for how education research contexts are perceived and represented. This discussion uses the concept of materiality to demonstrate how the conceptualization of inquiry through digital…

Coded experience and effective semiotic systems, organizations of patterns of signs that comprise a system of meaning, have proved essential for the propagation of knowledge. In education, communication via semiotic systems forms an important role in guiding children toward the effective use of information and techniques, and it is important that…

This study documented the processes of knowledge construction and knowledge representation in high school students' hypermedia design projects. Analysis of knowledge construction in linking and structural building yielded distinct types and subtypes of hypermedia documents, which were characterized by four features of knowledge representation: (a)…

Explains the origin and goals of cognitive flexibility theory and discusses new directions being explored. Topics include hypermedia systems; multiple knowledge representations; interconnectedness; context-dependency; digital video cases; experience acceleration; and bridging knowledge and practice, cognitive, individualistic practices and…

Describes a study of undergraduates that examined the potential trade-off in study efficiency and breadth of learning for hypertexts studied by selecting units from a content map. Compares study strategies and text recall with a more- and less-segmented hypertext and discusses text representations, study times, knowledge representation, and…

Hypertext can be characterized as an electronic system that works by association rather than indexing, and furnishes information in a dynamic, nonsequential manner that does not limit the content by structure or organization. A more technical definition specifies that hypertext is a technique for organizing information in a complex manner that…

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…

Users of educational hypertext are faced with the challenge of creating meaning both within and between texts. Cohesion is an important factor contributing to whether a reader is able to capture meaning and comprehend text. When readers are required to fill in conceptual gaps in text, comprehension can fail if they do not have sufficient…

Analyzes students' visual renderings of concepts related to the term "hypermedia" to determine whether groups, membership of which was based on a mixture of learning styles or a mixture of hypermedia knowledge, constructed concept maps that differed in terms of several factors. Learning style seemed to explain the types of interactions more than…

Proposes to strengthen the theoretical basis supporting hypermedia computer-assisted language-learning (CALL) authoring by initiating a requirements analysis based on contextualized conceptual and mental models, presenting the theoretical dimension of knowledge representations within the authoring process and applying the theoretical approach to…
