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…

This paper reports on a detailed investigation into the beliefs and practices of teachers in 22 computer-assisted learning projects in Australia in the mid-1990s. Detailed interview data were obtained, supported by the project software and other curriculum materials. The interview transcripts and documentary material were collated and condensed…

Examines problems of existing courseware authoring systems and suggests the use of knowledge-based techniques. A prototype knowledge-based representation language called GTE (Generic Tutoring Environment) is described that could form the basis of a full authoring environment, including generic tasks and instructional methods, domain knowledge, and…

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…

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)

Predictive evaluation of educational software is problematic because such instructional materials should be evaluated only setting by setting. A situated approach suggests that appropriate evaluation can be performed by considering interactions between the three principal actors in the development and use of the software: teacher, designer, and…

Discusses the possibilities for improving courseware and the courseware engineering process using visualization. Advantages and disadvantages of visualization are considered, including psychological, instructional, motivational, cross-cultural, and technical aspects; visual programming systems are described; adaptation and rapid prototyping are…

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…

Describes a spreadsheet system that enables students, teachers, and curriculum developers to use Microsoft EXCEL's database and graphics capabilities in the science classroom. System design goals are explained, examples of system applications are given, and possible future developments are discussed. (15 references) (LRW)

Discusses the use of multimedia techniques in computer-assisted learning (CAL) to help dyslexic children with spelling. An evaluation study that tested rule-based versus mastery-based approaches to spelling remediation is reported; problems that dyslexic children have with traditional CAL are discussed; and software that uses synthesized speech is…

Describes research project being implemented in the United Kingdom that has been developed to examine the process of change in secondary school students' conceptual understandings in the physical sciences. Models of conceptual change are described, the role of computer based activities in promoting conceptual change is discussed, and software…

Describes a computer simulation game and database package, "Palestine in the First Century," developed for upper primary and secondary school religious education in Scotland and designed for use on a microcomputer with a printer. The effect of this type of software on the role of teachers and students is considered. (Author/LRW)

Describes the production of a computer-aided, self-testing system for university students enrolled in a first-year course in biological psychology. Project aspects described include selection, acquisition and description of software; question banks and test structures; modes of use (computer or printed version); evaluation; and future plans. (11…

Describes software that was designed in the United Kingdom to promote conceptual change in secondary school students studying mechanics. Direct Manipulation of Mechanical Microworlds, an interactive computer simulation, and VARILAB, a computer-based language for modelling systems, are explained; and two studies that will evaluate the effectiveness…
