Discusses the nature of instructional design and describes rapid prototyping as a feasible model for instructional system design (ISD). The use of prototyping in software engineering is described, similarities between software design and instructional design are discussed, and an example is given which uses rapid prototyping in designing a…

This survey elicited experts' perceptions of factors affecting development and use of interactive technologies. Responses from 196 respondents were categorized as hardware/technology, software/programs, acceptance/adoption, accessibility/ease of use, and instruction/learning/communication issues. Based on this categorization, a model of…

Describes a basic development model for an intelligent tutoring system that includes the interface, the expert and learner models, and the pedagogical model. Possibilities for more extensive integration of cognitive learning theories into computer-based instruction (CBI) are illustrated, and two examples of CBI designed from this perspective are…

Discusses model-based simulation for training, explains an object-oriented approach, and describes RAPIDS, an authoring system for the production of interactive graphical models and instruction based on those models. Highlights include intelligent tutoring systems; transaction shells; tools for authoring models; and a course on retinal information…

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)

Reviews current empirical data on the effectiveness of animation in computer-based instruction. Research on static visuals and learning is examined; animation research is described that includes studies with elementary school children, high school students, and adult learners; and implications for current instructional design are suggested. (56…

Discussion of learner preferences for text densities on computer screen displays highlights two studies of college students that compared preferences for multiple or single screen presentations with high-, medium-, or low-density screens from an actual course using computer-assisted instruction. Results are analyzed, and further research needs are…

Describes the Space Shuttle Commander software package, which utilizes the dynaturtle microworld to teach elementary and middle school students about Newton's laws of motion. Design considerations for computer-based microworlds that represent a compromise between the philosophies of constructivism and direct instruction are presented. (91…

Summarizes the implications of constructivism for instructional systems design in five principles that integrate the affective and cognitive domains of learning. Distinguishing characteristics of the two approaches are described based on a review of recent literature, and examples are offered that discuss learner controlled computer-based…

Discusses myths underlying the curriculum, teacher knowledge of the curriculum, and constructivist perspectives of the curriculum that need to be considered if curriculum reform is to succeed. Goals, pedagogical features, a typical session, and field test evaluation results for the ScienceVision hypermedia system are described. Sample screen…

Discusses the integration of instructional science and computer science. Topics addressed include motivation for building knowledge-based systems; instructional design issues, including cognitive models, representing student intentions, and student models and error diagnosis; representing tutoring knowledge; building a tutoring system, including…

Proposes a schematic multidisciplinary model to help developers of intelligent computer-assisted instruction (ICAI) identify the types of required expertise and integrate them into a system. Highlights include domain types and expertise; knowledge acquisition; task analysis; knowledge representation; student modeling; diagnosis of learning needs;…

Discussion of computer-mediated communication (CMC) focuses on an international electronic Delphi study that was conducted to predict the prevalent instructional CMC applications that will be used in colleges and universities in the near future. Resources required for support and obstacles to be overcome are discussed. (Contains 81 references.)…

Reviews the evolution of instructional systems design and computer-based learning environments, focusing on the effects of technological advances. Classification of learning environments is discussed in the context of the dimensions of scope (macrolevel or microlevel), user activity (generative or mathemagenic), educational activity (goal-directed…

Discussion of user-friendly computer systems focuses on the use of learners' mental models to help in the design of interactive learning systems. Topics addressed include interactivity; human factors research; human-computer interface issues; individual differences, including learning styles and prior experience; cognitive load; measuring mental…
