The literature on instructional design argues that curricula, educational materials, and instructional strategies are best created using a systems approach, and models for the systematic design of educational programs have proliferated over the past decade. However, these models are prescriptive and not based on research into how designers…

Current notions of metacognition merge with the predominant scientific model used in psychology, that of information processing. Metacognition is seen as a control process that governs the action of more elemental cognitive skills. Given the centrality of this notion, it is important that metacognition should be examined in detail. From the point…

Some diverse fields in which the effects of mental representations have been noticed are first discussed, largely through illustrations of differing problem-solving experiences. Then the LAKOS Project (Logical Analysis of Cognitive Organizational Structures) at the University of Osnabruck is described. A central concern is the specification of a…

Different kinds of basic knowledge and strategies necessary for comprehension are examined in three radically different domains: (1) the stories, (2) mathematical problems, and (3) electronic circuits. From analyzing the comprehension processes in these different domains, similarities have emerged in the role of planning knowledge and the…

Part of a sustained program that has involved the design of personally tailored information systems responsive to the needs of scientists performing common research and teaching tasks, this project focuses on the procedural and content requirements for accomplishing need diagnosis and presents these requirements as specifications for an…

The 34 summaries contained in this collection represent the theoretical positions and the empirical studies of a wide variety of investigators currently working in the field of language comprehension. The entries summarize contributions from the areas of assessment, artificial intelligence, cognition (including schema theory), instruction,…

Student projects that involve writing generative grammars in the computer language, "LOGO," are described in this paper, which presents a grammar-running control structure that allows students to modify and improve the grammar interpreter itself while learning how a simple kind of computer parser works. Included are procedures for…

Describing cognitive science as a new discipline based upon the integration of elements of psychology, computer science, linguistics, philosophy, and education, this paper argues that such a discipline has important implications for the field of communication. Following an overview of the literature of cognitive science, the paper offers an…

A major obstacle to the effective educational use of computers is the lack of a natural means of communication between the student and the computer. This report describes a technique for generating such natural language front-ends for advanced instructional systems. It discusses: (1) the essential properties of a natural language front-end, (2)…

This article provides a tutorial introduction to Artificial Intelligence (AI) research for those involved in Computer Assisted Instruction (CAI). The general theme is that much of the current work in AI, particularly in the areas of natural language understanding systems, rule induction, programming languages, and socratic systems, has important…

TORTIS (Toddler's Own Recursive Turtle Interpreter System) is a device which can be used to study or nurture the cognitive development of preschool children. The device consists of a "turtle" which the child can control by use of buttons on a control panel. The "turtle" can be made to move in prescribed directions, to take a…

The course in parsing English is essentially a survey and comparison of several of the principal systems used for understanding natural language. The basic procedure of parsing is described. The discussion of the principal systems is based on the idea that "meaning is procedures," that is, that the procedures of application give a parsed…

A basic unsolved problem in science is that of understanding learning, the process by which people and machines use their experience in a situation to guide future action in similar situations. The ideas of Piaget, Pavlov, Hull, and other learning theorists, as well as previous heuristic programing models of human intelligence, stimulated this…

A series of five interdisciplinary conferences held over a two-year period explored new teaching and training concepts and methodologies which offer powerful, symbiotic means of augmenting human cognition. The basic discussion points of the conferences are summarized. It was felt that the conferences were significant in that they brought together…

This report considers the problem of constructing an abstract model of story comprehension. The use of questions that go beyond the story as a test of understanding the story raises a methodological problem which is discussed in detail. (Author)
