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…

Computers can be used in a variety of ways in the social studies classroom: (1) as a productivity tool to relieve the teacher of the many bookkeeping tasks and allow for more time to be spent on instructional tasks; (2) in business applications such as data base files, electronic spreadsheets, word processing, computer graphics, and to store large…

Bender Gestalt Test data from 60 severely emotionally handicapped and 60 normal children were computer digitized and scored traditionally. Reliability results from comparison of analysis techniques favored computer approach; criterion-related validity was unsuccessful for both scoring methods; and concurrent validity results indicated limited…

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…

During the first 12 weeks of an applied calculus course, two classes of college students studied calculus concepts using graphical and symbol-manipulation computer programs to perform routine manipulations. Three weeks were spent on skill development. Students showed better understanding of concepts and performed almost as well on routine skills.…

Presented are ideas for the utilization of Microsoft Works in the secondary mathematics classroom. The spreadsheet and graphing capabilities of this software package are demonstrated for several topics including the concept of slope for first year algebra, and creating and interpreting graphs for a general mathematics class. (Author/CW)

Described is a computer algorithm for obtaining the coordinates of vertices, chord factors, and dihedral angles for plotting orthographic and axonometric projections, and for tabulating chord lengths and dihedral angles. (Author)

This paper explores the role of computerized simulations as a decision-modeling intervention strategy, and views the strategy's different attribute biases based upon the varying primary missions of instruction versus application. The common goals associated with computer simulations as a training technique are discussed and compared with goals of…

Indicates that increased exposure to different objects in teaching orthographic projection benefits students, especially when they can manipulate and see the surfaces, points, and lines simultaneously or sequentially in three views. Positive attitudes and increased scores were noted after students used interactive computer graphics in an…

The production and application of images based on fractal geometry are described. Discussed are fractal language groups, fractal image coding, and fractal dialects. Implications for these applications of geometry to mathematics education are suggested. (CW)

Hardware for computer-assisted learning is discussed in three papers. Two papers report on projects using computer graphics, one for teaching structural analysis to university students and the other to teach graph concepts at the secondary level. Guidelines for selecting microcomputers focus on analyzing applications and matching them with…

Discusses computer assisted instruction programs that deal with the specific area of the modeling of systems and the programing techniques that affect their educational value. An environment intended to increase the impact of interactive CAI is described and developed. (Author/CHC)

This paper discusses a "language lab" strategy in which traditional studio learning may be supplemented by language lessons using computer graphics techniques to teach architectural grammar, a body of elements and principles that govern the design of buildings belonging to a particular architectural theory or style. Two methods of…

Computer graphing makes it easier for students and teachers to create and manipulate graphs. Scale issues are nearly unavoidable in the computer context. In interviews and protocol analysis with six students from grade 8, and 12 students from grades 11 and 12, it became apparent that some aspects of scale are clearly understood very early while…

Reports on a study of seven preschool children engaged in drawing activities with traditional media (crayons, felt-tip pens, etc.) and a mouse-driven computer paintbox program. Finds that the same basic media-independent strategies are used when children try to establish a relationship between their mark-making actions and the resultant effects.…
