The Coach system, a computer simulation of a human tutor, was constructed with the goal of obtaining a better understanding about how a tutor interprets the student's behavior, diagnoses difficulties and gives advice to a student learning a simple computer programming language. Coach is based on a hierarchy of active schemas representing the…

The purpose of this research effort was to develop and evaluate a prototype system-independent Programming Design Guide (PDG) for one of the 13 offline job aids previously developed for use with the Instructional Systems Development (ISD) model. This PDG is intended to provide all of the guidance necessary for a user to implement the job aid on…

A transformational model offers a way to eliminate the middleman (programmer) in acccessing a computerized data base. It provides a basis for the algorithms which analyze the input query. The linguistic analysis of the sentence string is translated into system terms and the required operations are carried out. (28 references) (Author/NH)

In order to devise an aid for the teaching of formal languages and automata theory, a system was developed which allows a student to design, test, and change automata in an interactive manner. This process permits the user to observe the step-by-step operation of a defined automaton and to correct or alter its operation. Thus, the need for lengthy…

Intelligent relationships with people are among the goals for tomorrow's computers. Knowledge-based systems used and being developed to achieve these goals are discussed. Automatic learning, producing inferences, parallelism, program languages, friendly machines, computer vision, and biomodels are among the topics considered. (JN)

The five technical working papers that comprise the two volumes of this document are related to the problem of creating a valid process model of human communication in dialogue. In Volume 1 both papers consider reference as a phenomenon in text. The first surveys reference identification and resolution methods in various existing natural language…

The technical working papers that comprise the two volumes of this document are related to the problem of creating a valid process model of human communication in dialogue. In Volume 2, the first paper concerns study methodology, and raises such issues as the choice between system-building and process-building, and the advantages of studying cases…

Studies of natural dialogue indicate that people interact according to established patterns which are organized around the participants' goals. These patterns have been represented by a set of knowledge structures called "Dialogue-games" which are founded on conventional knowledge about communication and its uses to achieve goals. The…

The general goal of this research and development program was to facilitate man-machine communication in areas of high military impact, including on-line computing in communications, command, and control. Highlights of this research include: identification of major causes of man-machine communication difficulty for the computer-naive; discovery of…

Nearly 150 papers presented at this conference, sponsored by the International Federation for Information Processing, are included in this volume which surveys the state of the art of computer education. Nine papers provide an overview on such topics as computer science and mathematics, computer education in the 1970's, computers and the…
