Artificial neural networks (ANN), part of artificial intelligence, are discussed. Such networks are fed sample cases (training sets), learn how to recognize patterns in the sample data, and use this experience in handling new cases. Two cognitive roles for ANNs (intelligent filters and spreading, associative memories) are examined. Prototypes…

Discussion of the use of virtual reality in higher education looks at how this emerging computer-based technology can promote learning that engages all seven forms of intelligence proposed in H. Gardner's theory of multiple intelligences. Technical and conceptual issues in implementation of virtual reality in education are also examined.…

A framework for examining the effectiveness of different types of educational computing environments addresses the conceptual characteristics of the knowledge domain being learned and the learner's stage of knowledge. Characteristics of certain technology-based learning environments (computer-based drill, intelligent tutoring systems, hypertext)…

A discussion of authoring system technology is based on a review of 80 products. Alternative authoring approaches are described; assumptions underlying development of authoring systems and their use are examined; selection procedures and criteria sensitive to varied needs are suggested; and trends in software development, evaluation, marketing,…

Trends in the use of visualization (computer graphics) for instructional purposes are analyzed in three segments: (1) current classroom activities; (2) technically possible but not prevalent classroom activities; and (3) the future classroom. The discussion draws on University of Iowa efforts, national curricular innovations, and presentations and…

Literature on the influence of computers on learning in formal classroom and informal out-of-school contexts is reviewed, and the primary policy considerations in diffusion of computer-based educational technology are examined. The article suggests that the boundaries between formal and informal learning environments can be overcome with…

Computer-delivered, case-based instruction can provide medical students with valuable clinical diagnostic experiences before encountering real patients. Diagnosis requires physicians to understand and use causal reasoning for prediction. Such reasoning may be scaffolded in the design of computerized learning environments. Scaffolding of causal…

Increasingly, higher education institutions and businesses are developing distributed learning systems to provide continuing job-related and professional education. Principles and examples of distributed learning and support systems that promote individual development are outlined, considering issues of motivation, speed of program development,…
