In spite of the limitations of minicomputers, Western Washington State College (WWSC) has developed a useful interactive computing system based on a Model 7/32 Interdata minicomputer and the computer program, PILOT. The major disadvantages of minicomputers are the difficulty of securing maintenance and the reliance often on the single language,…

The Graphic Terminal Display System (GTDS) was created to support research and development in computer-assisted instruction (CAI). The system uses an IBM 360/50 computer and interfaces with a large-screen graphics display terminal, a random-access slide projector, and a speech synthesizer. An authoring language, GRAIL, was developed for CAI, and…

Computer Assisted Individualized Study Package (CAISP) is a set of computer programs in BASIC intended to help teachers administer individualized study courses. It is intended for use with computers that allow direct user interaction during program execution, and is written on the DEC 10 time shared computer. This report focuses on how to use…

This report describes the current version of the Why System, a script-based Socratic tutor which uses tutoring strategies formulated as production rules. The current system is capable of carrying on a dialogue about the factors influencing rainfall by presenting different cases to the student, asking for predictions, probing for relevant factors,…

This paper is a preliminary proposal to develop the theory and design for "coaches" for computer games, to implement prototypes, and to experiment with their ability to convey important intellectual skills. The focus of this project will be restricted to developing a coach for a single example of an intellectual game called Wumpus. It is…

The interactive system for creating graphic displays that is described is presented as one solution to the problem created by the lack of complementary firmware or software to make the graphic capabilities of many current terminals easily accessible to the instructional programmer. The use of this system by the Digital Equipment Corporation's…

Model building techniques from Artifical Intelligence and Information-Processing Psychology are applied to human-computer interface tasks to evaluate existing interfaces and suggest new and better ones. The model is in the form of an augmented transition network (ATN) grammar which is built by applying grammar induction heuristics on a sequential…

Earlier research by the authors in the design and use of computer-assisted instructional systems and curricula for teaching mathematical logic to gifted elementary school students has been extended to the teaching of university-level courses. This report is a description of the curriculum and problem types of a computer-based course offered at…

A computer-assisted instructional package designed to teach both specific series-solving skills and general problem-solving skills was run in a school environment for one year. Students had access to the program during their free time. This paper analyzes the progress made by one student in both series solving and general problem solving during…

This booklet describes two computer programs that were written to provide on-line aid to problem solvers. Both programs were designed for "membership" problems, or those in which there are several English sentences and implicit relationships. The task was to infer a membership structure that is compatible with all the logical constraints.…

This report covers the PLATO IV activities during calendar year 1973 at the Computerized Training System. The work reported herein is supported by a program sponsored by the Advanced Research Projects Agency (ARPA) to evaluate the PLATO IV system for use in training, oriented to the needs of the Armed Services. The report presents a synopsis of…

This document reports on a study of several characteristics of the Computer Based Education (CBE) lessons written at military training sites whose CBE projects were sponsored by the Defense Advanced Research Projects Agency (ARPA). The purposes of the study were (1) to demonstrate the potential of computer-based scanning of CBE programs as a means…

VOCAL (Voice Oriented Curriculum Author Language) is designed to facilitate the authoring of computer assisted curricula which incorporate highly interactive audio and text presentations. Lessons written in VOCAL are intended to be patterned after the style of informal classroom lectures. VOCAL contains features that allow the author to specify…

The computer assisted problem solving system (CAPS) described in this booklet administered "homework" problem sets designed to develop students' computational, estimation, and procedural skills. These skills were related to important concepts in an introductory statistics course. CAPS generated unique data, judged student performance,…

An electronics graphic symbol set for on-line construction of electrical and electronics schematic diagrams is described. Specific procedures involving off-line and on-line activities are presented for the development and entry of schematic diagrams utilizing a stored set of symbols. An example of the commands and coding required for the…
