A consultation quality control model (CQCM) developed for an expert system (ES) integrated both ES performance measures and end-user judgment values. Simple decision theory concepts were used to design the CQCM. Results show end users belong to different categories characterized by utility functions and the weights they assign to ES consultation…

Two studies of the cognitive processes involved in online document-based information retrieval were conducted. These studies led to the development of five computational models of online document retrieval which were incorporated into the design of an "intelligent" document-based retrieval system. Both the system and the broader implications of…

Presents an approach to developing viable image computer-human interactions (CHI) involving user metaphors for comprehending image data and methods for locating, accessing, and displaying computer images. A medical-image radiology workstation application is used as an example, and feedback and evaluation methods are discussed. (41 references) (LRW)

Schools and teachers are increasingly being held accountable for providing true learning activities to every student in the classroom. This accountability is measured through…

The pervasive popularity of the Internet in the past decade has changed the way many students live and learn, in part, because modern technology has made it possible for learners to access Real-Time Multimedia information on the Internet, or research any topic of interest to them from virtually any computer anywhere in the world. Students can also…

This study reports on our design of a computer system which supports the understanding of how students construct their mental representation of references and how the construction failures impede their reading comprehension. Three modules, "User interface", "Recording", and "Feedback" were implemented. The…

Persistent myths have lessened the impact of ICTs on education. Happily they are balanced by miracles of theory and practice that are gradually gaining the upper hand. We counter the myth that innovation in the application of ICTs is the preserve of industrialised countries by listing examples of innovations from southern Africa that have set…

Noting that the merging of various types of media with the computer has presented the field of education with a hybrid technology called interactive multimedia (also referred to as hypermedia), this digest begins by defining this technology as "the integration of text, audio, graphics, still image, and moving pictures into a single,…
