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…

Explores the subject of fractal geometry focusing on the occurrence of fractal-like shapes in the natural world. Topics include iterated functions, chaos theory, the Lorenz attractor, logistic maps, the Mandelbrot set, and mini-Mandelbrot sets. Provides appropriate computer algorithms, as well as further sources of information. (JJK)

Discusses the use of interactive computer graphics in developing student exercises on various concepts of electrical engineering. These exercises include drill and practice, homework, remedial work, and interactive laboratory reporting. In addition, a computer assisted program is used by instructors. (JN)

The integrated compiler of the Turbo Pascal environment allows the execution of a completed program independent of the developed environment and with greater execution speed, in comparison with LOGO. Conversion table of turtle-graphic commands for the two languages is presented. (Author/YP)

Describes the derivation of the parameters incorporated into computer programs that are utilized to draw hypocycloids, which are the loci of points traced out by a point on a disk as it rolls against a circle and its interior. Includes information to obtain copies of the programs described. (JJK)

Describes ways computers are used in the art education program of one elementary school. Illustrates how computers become centers where students learn to use the computer as a tool with which to experiment and make choices. The results of these experiments are then applied to their art work. (KO)

This article describes how the use of interactive molecular graphics makes a unique and important contribution to student learning of biochemistry and molecular biology at any level. These authors developed the concept of the kinemage (from "kinetic image"), a different way of organizing computer graphics that is aimed explicitly at the…

Computer graphic procedures can be adapted at low cost in order to teach the basics of layout and good design in high school and college journalism classes. Both journalism educators and students can benefit from computer equipment used as a vehicle for graphics experimentation. In addition to creating experimental newspaper and magazine page…

Scenario refers to specific courses of action/events occurring within computer simulations and attempting to recreate lifelike situations. This article identifies critical features and their elements in designing effective scenarios in computer-based instructional simulations: (1) sequence; (2) operating procedures; (3) characteristics of…

Reviews the use of microcomputers in the art studio and classrooms. Argues that there is a lack of effective software for art education, but that computers are useful for enhancing standard visual grammar. Suggests that the most legitimate educational use of computers is employing them to discover new ideas in better ways. (GG)

Presents the geometric, software-ergonomic, and educative standards for interactive graphics systems envisioned for planimetric constructions and calculations in secondary mathematics instruction. Describes the geometric-didactic potentials of the MS DOS-Version 1.6 of CABRI-Gomtre which is an Intelligent Tutoring System with the possibilities for…

A computer-based method of communicating syntactic knowledge to deaf students was designed, building on the visual orientation of deaf students and employing such American Sign Language techniques as visualization and directionality. The computer-based instructional treatments were presented as an educational game called the "Yes-No Game," with…

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)

This article discusses using individualized multimedia activity schedules as a technology-based instruction for young children with autism. The schedules serve as cues that can help students prepare for transitioning to between school activities. The benefits of using Microsoft PowerPoint in the classroom are described, along with implementation…
