Presents a group of semiotic principles for software design and uses them to show how they explain different educational possibilities. Discusses interface design and describes Theater in the Computer, a software environment for children, to illustrate semiotic-based principle of interface design. (Author/LRW)

Discusses the effects of individual differences and cognitive styles on student learning in hypermedia programs and presents a cognitive model to illustrate how students with different cognitive styles react to non-linear learning in hypermedia by analyzing the findings of previous studies. Suggests implications for the design of hypermedia…

Describes a prototype process for the development of educational multimedia materials, based on the ARKive project in the United Kingdom, which can help educational multimedia software developers produce more coherent and effective learning resources by making explicit the value/belief system on which the project is founded. (Author/LRW)

Provides an account of the design of the Lesson Planning System, a hypermedia performance support system (PSS) predicated on task performance to support novice teacher-education students in lesson planning. Reports on an initial research study to investigate the effectiveness of the software and discusses the role of PSSs in teacher education.…

Identifies key factors affecting conceptual gains from using a CAL (computer-assisted learning) package and their application to a college practical laboratory class. Considers students' biographical characteristics, design features of the CAL package, and the way that the CAL was integrated into the curriculum. (Author/LRW)

Examines the methodological common denominator among several models for courseware development and discusses in detail both the design and the validation phases. Emphasizes the need for a systematic approach in which multiple authors' skills are exploited and the cost-benefit ratio is kept at an acceptable level. (AEF)

Describes a computer-assisted learning program called Link, which was designed for psychology students to review their understanding of correlation. Results of a summative evaluation showed that use of Link contributed to students' understanding of correlation, as did the use of paper-based instructional materials. Suggests implications for…

Describes a dedicated method for the design of multimedia courseware, called PROFIL, which integrates instructional design with software engineering techniques and incorporates media selection in the design methodology. The phases of development are outlined: preliminary investigation, definition, script, technical realization, implementation, and…

Describes the evolution of courseware development and compares existing development methods, including traditional programing languages, authoring languages, and authoring systems. The use of a product which includes a customized courseware generator or authoring system is proposed, and an example is described that used HyperCard to teach the…

Describes a usability study conducted with health sciences students at the University of Washington that explored interface issues in the GramStain Tutor, an educational software program on CD-ROM, particularly the navigation of the program and the use of embedded design features. (LRW)

The Dynamic Courseware Generator (DCG), which runs on a Web server, was developed for the authoring of adaptive computer-assisted learning courses. It generates an individual course according to the learner's goals and previous knowledge, and dynamically adapts the course according to the learner's success in knowledge acquisition. The tool may be…
