Two experimental studies were carried out to investigate whether adding multimedia features in a concept mapping task would improve the quality of the map built by students and promote more effective learning with expository hypertexts. Ninety-Nine undergraduates built a concept map to learn about a topic (water cycle or nitrogen cycle) either…

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…

Adaptive Educational Hypermedia Systems (AEHS) play a crucial role in supporting adaptive learning and immensely outperform learner-control based systems. AEHS' page indexing and hyperspace rely mostly on navigation supports which provide the learners with a user-friendly interactive learning environment. Such AEHS features provide the systems…

Discusses a multimedia computer-assisted instruction training project at San Juan College (New Mexico) within the context of current research in the area. Research demonstrates that the complexity of hypermedia requires methodical management, cognitive factors limit the optimum number and types of hypermedia link displays, and close monitoring of…

Testing and evaluation are important components of effective instructional software development. Many evaluation approaches today are multifaceted, employing a combination of methodologies and multiple data collection techniques. In this paper, several approaches to evaluation are discussed. Computerized tracking systems, videotape recording…

This paper explores the insights that psychology can offer in shedding light on why hypermedia may work and thus in suggesting fruitful areas for future research. The philosophy underlying the paper is that research into the instructional efficacy of hypermedia should begin with a knowledge and appreciation of relevant psychological phenomena.…

In educational settings, computers provide specific possibilities of visualizing information for instructional purposes. Besides the use of static pictures, computers can present animated pictures which allow exploratory manipulation by the learner and display the dynamic behavior of a system. This paper develops a theoretical framework for…

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…

This annotated bibliography was developed as a result of a May, 1991, Technology Seminar on Multimedia, and is intended to provide researchers with an overview of the literature pertaining to the development of multimedia technology, innovative applications, design, and implementation issues as well as with descriptions of major multimedia…

A study evaluated the process of training teachers to use an interactive multimedia package for classroom instruction in ecology. Ways in which teachers assessed relevant printed text and hypertext information were mapped and analyzed. Search patterns were classified into two cognitive strategies (sequential, goal oriented). Sequential strategies…

For the twenty-ninth year, the Research and Theory Division of the Association for Educational Communications and Technology (AECT) is sponsoring the publication of these Proceedings. Papers published in this volume were presented at the National AECT Convention in Orlando, Florida. The Proceedings of AECT's Convention are published in two…
