Four- and 5-year-olds' understanding of basic turtle graphics commands was examined before and after a hands-on, interactive problem-solving experience. Children (n=32) saw display screen events consisting of an initial turtle state, a command transformation, and the resulting turtle state. They were asked to give the command executed in each…

Computer graphics are used to display the sum of the first few terms of the series solution for the problem of the vibrating string frequently discussed in introductory courses on differential equations. (MNS)

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)

Sixteen hearing-impaired adolescents received instruction in the graphics mode of the LOGO computing language. Eight of the students also received strategy training to enhance reflective problem solving and subsequently demonstrated fewer programing errors and improved problem-solving ability with LOGO, compared to controls. Highly impulsive…

Description of the field of robotics and its possible use in high school computational geometry classes emphasizes motion planning exercises and computer graphics displays. Eleven geometrical problems based on robotics are presented along with the correct solutions and explanations. (LRW)

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)

Suggests a series of ratio activities that make use of a computer to produce graphical collections of objects in a grid with variable dimensions. Extends content to the areas of proportions, statistics, probability, programming, and problem solving. (PK)

LogoWriter provides the means through which students of varying backgrounds and abilities can experience different types of learning. It involves using problem solving, graphing, critical thinking, and other creative strategies. The lessons provided in this book contain ideas that allow beginners to explore various areas of Logo while using…

Describes adventure games, a genre of computer simulation games that require the use of creative and intuitive approaches similar to those used in online database searching, and suggests that they can be used in training online searchers to develop creative problem solving skills. Reviews of several available adventure games are included. (EJS)

This book is designed to help teachers maximize their students' learning of Logo. It investigates what students learn when they learn Logo, and how teachers know what they are learning. The book is intended primarily for teachers at the upper elementary and middle school levels. Each chapter is devoted to a critical aspect of Logo learning, and…

Today's educational software has transcended original drill and practice functions to provide enjoyable learning experiences through simulation, tutorial, and special education programs that develop reasoning and problem-solving skills. Teacher and administrator effectiveness can be enhanced by lesson design, scheduling, attendance, grade…

Discusses conception, design, implementation, and evaluation of a calculus course that utilizes a multi-user microcomputer system with graphics terminals. The numerical and utility routines of the software are briefly described, and examples of several types of calculus problems that can be solved utilizing the system are reviewed. (Author/MBR)

Presented are abstracts of 10 papers presented at the 1984 National Educational Computing Conference. Paper topics deal with science teaching using microcomputers, exploring mathematical concepts with LOGO, a chemistry problem-solving program, interactive computer graphics in mathematics, an educational game to teach science/mathematics, learning…
