Design of educational multimedia rarely starts from scratch, but rather by attempting to reuse existing software. Although redesign has been an issue in research on evaluation and on learning objects, how it should be carried out in a principled way has remained relatively unexplored. Furthermore, understanding how empirical research on…

Discusses cognitive load theory and describes a study that investigated how undergraduates learned the basic commands of a CAD (computer-assisted design) software package using manuals with different formats of presentation of instructions. Results show that graphical interface, using a manual that juxtaposes text and screen images, was most…

In the Singapore primary school Mathematics curriculum, students are taught the model method that uses bar diagrams to visualize the problem structure in a given word problem. When these students progress to secondary school, they learn the algebraic way of solving word problems. Studies (e.g. Ng et al.) have shown that poor bridging of students…

Reports on an experiment in which a course in psychology was replaced by a mixed formula consisting of a CD-ROM complemented by seminars and workshops. The CD-ROM was conceived as a collection of documents linked together with Netscape facilities. Students searched through these documents for information to answer questions (challenges) on the…

Discussion of the development of educational software focuses on a project at the Dutch Open University to develop a pedagogical design specification method for educational software that is not bound to specific instructional design principles or learning theories. "SHOC-TOOL" is described as a supporting tool for use with interactive…

Effective teaching should focus the attention of learners to its essential aspects. It follows that instructional software can be designed in such a way that allows learners to experience the important variations in the critical aspects of the content to be learned. This paper reports on the experience of designing such special kinds of…

Discusses recent advances in cognitive theory and the design of computer-based instruction and suggests implications for the design of authoring tools and tutoring system shells. Highlights include the design of courseware; advanced organizers; knowledge representation; design evaluation; models of knowledge; models of errors; and models of…

Explains courseware abstraction as a method of creating generalized computer assisted learning (CAL) lessons that can then be applied to provide as many concrete examples as desired. Topics discussed include generative CAL; cost efficiency; lesson verification; student evaluation; and factually exhaustive lessons. (nine references) (LRW)

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…

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…
