Animated models explicate the procedure to solve a problem, as well as the rationale behind this procedure. For abstract cognitive processes, animations might be beneficial, especially when a supportive pedagogical agent provides explanations. This article argues that animated models can be an effective instructional method, provided that they are…

Two instructional design alternatives are described and discussed: (1) the supplantation model of Ausburn and Ausburn (1978), where learning strategies are built into the instructional materials; and (2) a generative design model, where strategies are "built" into the learner. These contrasting models are proposed as representing the…

This investigation of the encoding features of graphs begins with a description of a cognitive framework which allows designers to factor into the process of designing displays how people interpret the information found and what display properties are responsible for this interpretation. The framework also provides a performance measure for use in…

Description of several computerized tutoring systems is organized around types of knowledge any tutor must possess--subject area, student's information, and how to teach and communicate. Data and control structures of Meno-tutor are described to illustrate use of artificial intelligence to model the student, a domain, and teaching strategies. (MBR)

A group of American and Japanese psychologists, anthropologists, linguists, and computer scientists gathered at the University of California, San Diego, to exchange ideas on models of joint problem solving and their special relevance to the design and implementation of computer-based systems of instruction. Much of the discussion focused on…

Attempts to train learning strategies have not produced marked or lasting increases in academic IQ, probably because current training models fail to recognize the evolutionary nature of strategies acquisition. Empirical and theoretical evidence supports an incidental learning model, which engineers the instructional environment following study…

This report characterizes human problem solving in digital circuit design. Protocols of 11 different designers with varying degrees of training were analyzed by identifying the designers' problem solving strategies and discussing activity patterns that differentiate the designers. These methods are proposed as a tentative basis for assessing…

Different aspects of human-machine interaction are discussed in the five brief papers that comprise this report. The first paper, "Some Observations on Mental Models," discusses the role of a person's mental model in the interaction with systems. The second paper, "A Psychologist Views Human Processing: Human Errors and Other…

Presents a decision model for planning learner feedback in distance education courses with emphasis on college-level teaching. Knowledge components in information processing models of learning are described, task analysis for learning from text is discussed in terms of comprehension, and criteria for designing learner feedback are examined. (LRW)

Individual papers discussing various facets of human relationships with interactive computer systems present an analysis of direct manipulation interfaces; discuss notion of conceptual models shared by system and user and propose a design methodology for delivering models to users; and address the intelligibility of systems and importance of…
