Describes the construction of a model of computer-assisted instruction using a qualitative block diagram based on general systems theory (GST) as a framework. Subject matter representation is discussed, and appendices include system variables and system equations of the GST model, as well as an example of developing flexible courseware. (Contains…

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…

Describes an Environment for Courseware Use (ECU), an information system that requires that a courseware product be adaptable within the environment in which it is going to be used. The use of computers in educational organizations is discussed; the use of adaptable products in an ECU is considered, and information modeling of environments for…

Introduces and demonstrates a quick-prototyping model for educational software development that can be used by teachers developing their own courseware using an object-oriented programming system. Development of a courseware package called "The Match-Maker" is explained as an example that uses HyperCard for quick prototyping. (Contains…

Discusses collaborative authoring, computer-supported collaborative work and the reuse of multimedia courseware; describes a consolidated model, Open Systems for the Collaborative Authoring and Reuse (OSCAR) of courseware, that was drawn from other abstract models; and examines hypermedia systems, object-oriented communication models, and the…

This document consists of a number of figures and diagrams suitable for overhead transparencies that illustrate and elaborate on the prnciples of failure-oriented training (a model for improving the effectiveness of instructional analysis). By adding a few simple steps to analysis, the resulting training will be closer to the idealized tutor:…

Describes the inadequacies of the current software for computer-based instruction, and presents a framework of instructional components to guide the design of such software. A taxonomy of design considerations is then discussed, including instructional context, strategies, and technical capabilities that can be used to enhance instruction. (4…

Briefly discusses current views of the way anxiety decreases students' learning from instructional software and describes ways software designers might compensate for the learning problems of anxious students. (MBR)

Presents an approach to microcomputer courseware design that follows the engineering systems model and discusses areas of expertise needed by courseware designers, key courseware design questions, the accompanying teacher's guide and its components, and evaluation criteria teachers need to remember before purchasing instructional programs. (MBR)

Defines prototyping as an original version or model on which a completed software system for computer-based training is formed; examines the development process of a prototype; describes how prototyping can assist in facilitating communication between educational technology, software engineering, and project management; and discusses why…

Argues that the traditional reliance on scholarly research and publication for promotion and tenure needs to be reexamined as professors spend increasing amounts of time developing computer courseware. The creation of new models for teaching and research that will include educational computing as a valued part of the educational process is…

Presents an instructional development model that incorporates formative evaluation techniques, and explores the possible application of the model in developing computer-assisted instruction courseware. Advantages and disadvantages of this approach are identified and implications for research on formative evaluation are discussed. (31 references)…

Describes a naturalistic paradigm and discusses the value of using a naturalistic, or qualitative, approach to study the effectiveness of computer-based instruction (CBI) and to design effective courseware. Topics discussed include data collection; data analysis; and findings of naturalistic studies of CBI effectiveness. (53 references) (LRW)

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…

Reconsiders and affirms the general model of factors that influence the portability potential of educational software by summarizing the articles in this special issue. Factors that received the most attention include software design and development; overall instructional approach; teacher training; and cultural assumptions. Areas for further…
