This paper presents a model of an abstract tutorial system. The first section discusses some of the problems encountered in producing courseware and examines the availability of software tools to support effective communication on three levels: (1) accuracy of communication; (2) transmission of the desired meaning; and (3) affecting conduct in a…

Proposes a method for evaluating courseware as an integral part of curriculum, based both on "curriculum commonplaces" (the curriculum content and all that surrounds it) and on educational values and beliefs; an evaluative matrix is offered, with the commonplaces arrayed along one axis, values and beliefs along the other. (MCG)

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…

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 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…

This paper discusses the styles of computer-based learning and computer-based training in terms of their fundamental characteristics, including balance of control between program and learner, and the kinds of learning activity they induce. Learning and training are not considered to be intrinsically different in practice, and styles such as…

Arguing that the systematic application of knowledge about instruction to videodisc technology is essential if the full potential of this medium is to be realized, this paper begins by discussing the need for intelligent videodisc technology in our educational system. A brief review of the state of the art in intelligent videodisc systems, which…

Describes an instructional design model for hypertext, the Explorer's Hypertext Story Model, which is structured around components based on a story or narrative structure. Topics discussed include learner motivation; navigation in hypertext; learner control; and the importance of understanding information in context. (34 references) (LRW)

Examines the history, characteristics, and value of designed instruction that is grounded in behaviorist, cognitive science, and constructivist theory. Changes that have allowed developmental phases of instructional design are considered, including instructional design methodology, physical technology, and programing mechanisms used to develop…

Reviews current educational software evaluation methods, highlights problems, and describes the York Educational Software Evaluation Scales (YESES), an alternative criterion based model. Panel evaluation used by YESES is explained and YESES results are compared with evaluations from the Educational Products Information Exchange (EPIE) to indicate…

Arguing that what sets the computer apart from all other teaching devices is its potential for interactivity, this paper examines the concept of interactivity and explores ways in which its power can be harnessed and put to work. A discussion of interactivity in human-to-human communication sets a context within which to view human/computer…

This discussion of a major problem area in education--the curricular and implementation aspects of the application of the computer or new information technologies--focuses first on the use and integration of computers in existing courses or subjects in the curriculum, and defines some key terms. The next section considers issues in the…
