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)

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)

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…

A proposition that 3-D CAD provides an array of unambiguous solutions to engineering problems is illustrated. This proposition assumes that engineering problems are conceived in parallel processing mode while they are solved in sequential processing mode. Circle construction analysis, parallel equidistant planes, and solid modeling are discussed.…

An approach to reduce the barrier between two-dimensional computer-aided drafting and three-dimensional constructive solids modeling is graphically illustrated. This process, or some derivative, encompasses a significant portion of the future direction for engineering graphics education. (KR)

The existing methods for graphically illustrating projection and coordinate systems for manual and computer-aided drafting and design are examined. Inconsistencies in methods used to graphically depict first and third angle projection in texts and the lack of attention in the relationship of projection to coordinate systems are noted. (KR)

An algorithm is described for generating smooth curves of first-order continuity. The algorithm is composed of several cubic Bezier curves joined together at the user defined control points. Introduced is a tension control parameter which can be set thus providing additional flexibility in the design of free-form curves. (KR)

Parallel Alternative Strategies for Students (PASS) is a content-centered package of alternative methods and materials designed to assist secondary teachers to meet the needs of mainstreamed learning-disabled and emotionally-handicapped students of various achievement levels in the basic education content courses. This supplementary text and…

Defines computer literacy and describes a computer literacy course which stresses ethics, hardware, and disk operating systems throughout. Core units on keyboarding, word processing, graphics, database management, problem solving, algorithmic thinking, and programing are outlined, together with additional units on spreadsheets, simulations,…

Reviewed are 41 software packages. Many topic areas are covered. A brief synopsis, grade levels, hardware requirements, and approximate cost are included. A list of 23 software producers is included. (CW)
