A comparison between computer and student solutions to a location problem indicates a possible strategy utilizing planner-computer collaboration. (RA)

A theory of the planning and debugging of computer programs is formalized as a context free grammar, which is used to reveal the constituent structure of problem solving episodes by parsing protocols in which programs are written, tested, and debugged. This is illustrated by the detailed analysis of an actual session with a beginning student…

The application of Bezier polynomials in computer graphics to generate curves and surfaces is presented. The use of these curves to aid in the design of automobiles is featured, and a BASIC program designed to draw a simple caricature is included. (MP)

A unified theory of planning and debugging is explored by designing a problem solving program called PATN. PATN uses an augmented transition network (ATN) to represent a broad range of planning techniques, including identification, decomposition, and reformulation. (The ATN is a simple yet powerful formalism which has been effectively utilized in…

Discusses a unique computer application called interactive art. The technique involves a series of events in which individuals/groups interact with sensors and television monitors hooked up to a central microcomputer. Numerous examples are provided to illustrate that individuals need not be passive in their entertainment, art appreciation, or…

PATN is a design for a machine problem solver which uses an augmented transition network (ATN) to represent planning knowledge. In order to explore PATN's potential as a theory of human problem solving, a linguistic approach to protocol analysis is presented. An interpretation of a protocol is taken to be a parse tree supplemented by semantic and…

Three papers focus on applications of computer graphics with deaf and severely language impaired children. The first describes a drawing tablet software that allowed students to use visual and manipulative characteristics to enhance problem solving and creativity skills. Students were thus able to solve problems without the obstacles of language.…

How a computer randomly generates numbers to turn off lighted blocks on a graphics display is discussed. A computer program is given after reviewing a definition and two theorems and applying them to the problem. (MNS)

A hungry worm is looking for something to eat according to very specific rules, and the path he takes is a graph. The problem is detailed in Applesoft BASIC using low resolution graphics for worms that turn 90 degrees and high resolution for worms that can turn 45 degrees. (MP)

Discusses constructive ways to use microcomputers as educational aids. Areas considered include software packages with graphics capabilities to help students visualize their work, programs fostering skill development (including problem-solving), microcomputer rentals, use of computers to learn programing languages, and others. (JN)

The difficulty many students have in solving complex problems stems not from a lack of mathematical skill but from an inability to visualize the problem. An appropriately-structured computer game may assist students in achieving this visualization and in solving problems better. A heuristic approach in programing one game is provided. (Author/JN)

A set of programs, designed to supplement a high school or college course in trigonometry, is described. Student exploration is stressed. (MP)

Describes some commands, simple programing procedures, and applications of the programing language LOGO, including its powerful recursive feature and its value in teaching problem solving. A listing of LOGO graphics packages includes details of software and print materials, prices, and microcomputers that will support the packages. (EAO)

This paper describes the history, philosophy, and outcomes of work at the Educational Technology Center at the University of California, Irvine, with particular emphasis on the activities of the Physics Computer Development Project. Ten years of evolution for the physics projects and its basis of grant support are examined, and a series of…

Computer-assisted instruction supplements traditional methods in a non-calculus physics course offered at Seattle Pacific College. Thirty-five science majors enrolled in the first quarter and 32 continued in the second term. The hardware for the course consists of a PDP-11/20 computer and eight teletype terminals; additional peripheral equipment…
