A central issue in the development of multimedia systems is the presentation of the information to the user of the system and how to best represent that information to the designer of the system. Typically, the designers create a system in which content and presentation are inseparably linked; specific presentations and navigational aids are chosen [...]

Cognitive Media and Hypermedia Learning Environment Design: A GOMS Model Analysis
In our research, we have been developing a design framework for educational multimedia, based on the cognitive aspects of the users of that information. Design based on “cognitive media” appeals to the particular cognitive aspects of learners, whereas design based on types of “physical media” appeals to particular sensory modalities. This framework informed the design [...]

The Role of Student Tasks in Accessing Cognitive Media Types
We believe that identifying media by their cognitive roles (e.g., definition, explanation, pseudo-code, visualization) can improve comprehension and usability in hypermedia systems designed for learning. We refer to media links organized around their cognitive role as cognitive media types (Recker, Ram, Shikano, Li, & Stasko, 1995). Our hypothesis is that the goals that students bring [...]

Exploring Interface Options in Multimedia Educational Environments
Multimedia technology presents several options to the developers of computer-based learning environments. For instance, it is common to organize information by its physical characteristics. However, organizize information based on how users understand the material might improve comprehension. This theory of cognitive media – media organized by cognitive characteristics – was examined in studies using the [...]

Evaluating the Structural Organization of a Hypermedia Learning Environment using GOMS Model Analysis
Network-accessible hypermedia environments offer the potential for radically changing the nature of education by providing students with self-paced access to digital repositories of course information. However, much research is still required to identify ways to best organize, present, and index multimedia information to facilitate use and learning by students. We have been developing a theory [...]

Structuring On-The-Job Troubleshooting Performance to Aid Learning
This paper describes a methodology for aiding the learning of troubleshooting tasks in the course of an engineer’s work. The approach supports learning in the context of actual, on-the-job troubleshooting and, in addition, supports performance of the troubleshooting task in tandem. This approach has been implemented in a computer tool called WALTS (Workspace for Aiding [...]

Cognitive Media Types for Multimedia Information Access
Multimedia repositories, libraries, and databases offer the potential for providing students with access to a wide variety of interconnected information resources. However, in order to realize this potential, multimedia systems should provide access to information and activities that support effective knowledge construction and learning by students. This article proposes a theoretical framework for organizing information [...]
