Learning has transcended into a life-long endeavor in the information age. It is no longer restricted to confines of formal classrooms. Consequently, a student is not restricted to traditional learning resources like teachers, textbooks or printed content. Digital resources available on the Internet form a very significant component of…

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…

In order to improve the learning process for students with different pre-knowledge, personal characteristics and preferred learning styles, a certain degree of adaptability must be introduced to online courses. In learning environments that support such kind of functionalities students can explicitly choose different paths through course contents…

Interactive learning environments (ILEs) are increasingly used to support and enhance instruction and learning experiences. ILEs maintain and display information, allowing learners to interact with this information. One important method of interacting with information is navigation. Often, learners are required to navigate through the information…

Discussion of navigation buttons in instructional hypermedia programs focuses on a study of college students that investigated the effectiveness of buttons with pictorial representations, buttons with text and pictorial representations, and buttons with text only. Findings indicate that buttons with text labels reduce user confusion concerning…

Pathfinder is a graphic theoretic technique used to analyze proximity data. This study evaluates its validity: (1) for representing and comparing individuals' navigation through a computer-based hypermedia environment; and (2) for generating an empirically-derived path that represents a set of individual navigational paths during computer-assisted…

Discusses navigation in instructional hypertext programs and describes two preliminary studies that investigated concrete versus abstract representations for backward navigation. Topics include representation and hypermedia sign systems; and consistency in the forms designers use for navigation buttons. (LRW)

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…

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)

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)

Describes a study that investigated the effects of visual control (self-controlled versus system-controlled) and gender difference on learning with scientific multimedia instruction, observed how boys and girls differed in navigating and processing visual information in a hypermedia environment, and examined how visual control influenced learning.…

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)

Describes a study of undergraduates that enhanced a hypertext environment with a graphical overview that represented the basic domain structure and designed the layout so learners were unobtrusively encouraged to follow a sequence of exploration that followed the domain structure. Results indicated that a visual display conveys knowledge in its…

Describes a study of fifth graders that examined the effects of learner control and navigational aids on performance in a hypermedia instructional program. Results indicated that students who moved freely within the program and had access to navigational aids, interacted more with the program and achieved higher performance on posttests.…

Describes a study of high ability, highly verbal fifth-grade students that was conducted to identify students' use of learning strategies, their encoding processes, and their navigational decisions in a hypermedia lesson on propaganda techniques which contained an associative-linked structure.
