Describes the "Knowledge Board," a comprehensive integrated writing environment for professionals who write complex documents. Program functions, including navigational capabilities, an automated note card file, information sorting, information weaving, a function to organize information logically, and a revision function are examined. (Contains…

Explores how computer-mediated systems may support the professional development of adults by providing environments which allow individual needs and purposes to be met and experience and understanding to be shared. Highlights include descriptions of JITOL (Just in Time Open Learning), a project which combines computer-mediated communications with…

Investigates the effects of two hypermedia interface design strategies on learner efficiency, perceptions of usability, and performance. Compares undergraduate student outcomes of comprehending and locating information by using manual and visual filtering via computers. Findings support the use of these filtering tools as methods of increasing…

Analyzes student use of a multimedia chemistry instructional program used in an undergraduate chemistry course. Examines student time spent on the software and student use of the software's media components. Finds that students have different usage patterns for completing the same assignment, indicating that students are able to use individual…

Describes a study that explored the acquisition and transfer of complex knowledge after using a conceptually-indexed hypertext learning environment based on cognitive theory and research. Results found evidence that a hypertext learning environment with conceptually-indexed case-based materials and modeling/scaffolding support can help…

Describes design methods used to influence user perception of time in virtual learning environments. Examines the use of temporal cues in medical education and clinical competence testing. Finds that user perceptions of time affects user acceptance, ease of use, and the level of realism of a virtual learning environment. Contains 51 references.…

Evaluates the effectiveness of multimedia instruction by comparing student performance in two computer science classes at the University of Hawaii at Manoa. One class was taught using multimedia instruction and the other was taught using traditional instruction. Results suggest that multimedia courseware enhances computer science instruction and…

Presents a theory of configurational validity for analyzing ethnographic multimedia narratives that have been layered with contributions by multiple authors. Describes a software tool that addresses the use of configurations to build more valid narratives. Recommends that multimedia designers collaboratively design tools to help authors and users…

Proposes a theory for organizing information and activities in educational hypermedia systems and evaluates theory effectiveness based on implementation of a multimedia learning environment. Results suggest that self-paced interactive learning environments, multimedia information access, and constructive activities organized into cognitive media…

Proposes a model for online hypermedia courseware that presents information in a controlled and predefined structure. Measures and evaluates the model's impact on design time and student study time. Finds positive improvements in delivery and dissemination of technical subject matters and provides a better understanding of required development…

Assesses hypermedia design issues and examines how learners access information in a hierarchically organized hypermedia environment. Evaluates three browsing methods: "hotwords" and two distinctively different cognitive mapping architectures. Results suggest that the inclusion of a properly constructed cognitive map can diminish feelings of…

Presents a connectionist approach to modeling that relies on neural networks to control conventional simulations of multimedia clinical patient simulations. These neural networks simplify the medical expert's task of validating and maintaining patient simulations with diagnostic capabilities and serves as the basis of clinical decision support…
