Describes the design principles of computer-assisted learning (CAL) environments in which the software is interactive yet adaptable to different styles of learning and teaching, illustrated with a mathematics application. Following implementation, initial evaluation data taken from students showed marked performance improvements, and indicated how…

Defines portability of educational software; examines research regarding the portability of educational materials; considers barriers to portability; describes a research project conducted at the University of Twente (Netherlands) concerning the portability of computer-related educational resources, including networked learning environments; and…

Examines the issue of help devices for students in hypermedia environments according to the learning context and cognitive processes involved. Describes three main types of learning situations--learning-by-doing, learning-by-instruction, learning-by-exploring--and explores the main cognitive processes involved in them. Discusses specific types of…

Presents three trends in education separately: distance learning, ITS systems, and media-oriented learning. Benefits of their integration are considered along with the possible pitfalls and a short systematic approach on how to avoid them. In conclusion, some open questions in the field are discussed.
