Comments on the preceding article which examined elaboration theory and offered suggestions for updating it to reflect new knowledge. Highlights include the simplifying conditions method; internal versus external knowledge structures; connectionism and authentic tasks; content structure as organizing structure; ill-structured domains; and…

Describes the impact of the tools being developed as part of the Second Generation Instructional Design (ID2) Research Program on the process of instructional design. Highlights include domain semantic meaning; instructional design expert systems; rapid prototyping; the instructional systems development process; and the ID2 rapid prototyping…

Discusses the integration of multiple learning goals, or objectives, into instructional design procedures. Models of instructional design are described with emphasis on human performance factors; categories of integrative goals are explained, including denoting, manifesting, and discovering; and implications for the transfer of training are…

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…

Explains chaos theory; compares a conventional instructional systems design (ISD) approach with chaos theory and dynamic nonlinear systems, including deterministic predictability and indeterministic unpredictability and negative and positive feedback; explores theoretical implications for developing an alternative ISD model; and recommends future…

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 elaboration theory, an instructional design model for sequencing and organizing courses that is based on cognitive research, and offers suggestions for updating the model to reflect new knowledge. Topics addressed include knowledge representation, including content structure; sequencing issues, including microworld design and cognitive…

Analyzes the philosophical assumptions underlying instructional systems technology (IST). Cognitive and behavioral learning theories are discussed, their effects on IST are considered, the philosophical paradigms of objectivism and constructivism are compared, applications of constructivism are described, and implications of constructivism for IST…

Discusses concept learning research and theory, and examines the relationship with models of instructional design. Topics discussed include how concepts are learned; how concepts are measured; instructional design for concept learning; inferences; teaching with analogies; use of learning strategies; and new strategies for classification…

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…

Discussion of procedures for selecting appropriate media in instructional development projects highlights a study that examined media selection decisions of instructional development graduate students under intuitive and model-directed decision-making conditions. Use of the Reiser-Gagne media selection flowchart is described, and implications for…

Discusses the Jasper Woodbury Problem Solving Series, a video-based instructional macrocontext for complex mathematics problem generation and solving. A theoretical framework of assumptions about goals, learning, instruction, and learning materials is provided. Design features and typical teaching activities are described. Three teaching models…

Discussion of instructional systems development (ISD) focuses on recent developments in cognitive task analysis and describes the Integrated Task Analysis Model, a framework for integrating cognitive and behavioral task analysis methods within the ISD model. Three components of expertise are analyzed: skills, knowledge, and mental models. (96…

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)
