This paper describes a Prolog execution model which serves as the uniform basis of textbook material, video-based teaching material, and an advanced graphical user interface for Prolog programmers. The model, based upon an augmented AND/OR tree representation of Prolog programs, uses an enriched "status box" in place of the traditional…

A study was devised, using 20 undergraduate students chosen at random from an introductory psychology course, to measure the teaching effectiveness of two computer tutorials oriented to the spreadsheet portion of Appleworks. The first tutorial provided a data disk with pre-entered data for the user to manipulate, but no error correction…

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…

This paper describes GUIDON-WATCH, a graphic interface that uses multiple windows and a mouse to allow a student to browse a knowledge base and view reasoning processes during diagnostic problem solving. The GUIDON project at Stanford University is investigating how knowledge-based systems can provide the basis for teaching programs, and this…

Three major approaches to the use of computers in education are examined, serious limitations of each are presented, and questions are raised as to the efficacy of technologolizing education. The drill and practice approach is shown to embody a deterministic, behavioral technology that turns learning into a systematically-designed and…

This study explored the effectiveness of "high" user-friendly instructional text editors versus "low" user-friendly editors in teaching word processing to adult females. Whether subjects having higher positive attitudinal scores toward technology would perform better with computerized instructional materials as facilitators for…

GUIDON is an intelligent computer-aided instruction (ICAI) program for teaching diagnosis, which has been tested using the infectious disease diagnosis rules of the MYCIN consultation system developed at the Stanford University School of Medicine. GUIDON engages a student in a dialogue about a patient suspected of having an infection and thus…

Designed to focus on student learning and to illustrate techniques that might be used with computers to facilitate that process, this paper discusses five types of computer use in educational settings: (1) learning ABOUT computers; (2) learning WITH computers; (3) learning FROM computers; (4) learning ABOUT THINKING with computers; and (5)…

This paper presents research on the concept of idealized learning environments called Havens that facilitate learning, introduces the topic of technologically-created Havens, and discusses various components of Havens that can facilitate comprehension. Three experiments involving college students at Vanderbilt University are described. Designed to…

This study combines quantitative and ethnographic methods to analyze middle-school students' uses and understandings of microcomputers and videotex. As an experiment in teaching library research skills, 27 eighth graders were assigned to search an online encyclopedia in preparation for writing a science theme. The students' operational practices…
