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)

Described is an investigation into how the use of LOGO programing language affects children's basic knowledge of an angle. Findings indicate that children make erroneous adjustments to their conceptual knowledge of angle to accommodate the results of acquired procedural interaction with the computer. (Author/CW)

Reports the results of the third survey of computer use in engineering education conducted in the fall of 1987 in comparing with 1981 and 1984 results. Summarizes survey data on computer course credits, languages, equipment use, CAD/CAM instruction, faculty access, and computer graphics. (YP)

Describes a function graphing program's 15 Logo procedures and how they are used in the classroom to study the properties of functions and to develop visual imagery of function behavior. Presents several Logo programs. (Author/YP)

This unit is designed to acquaint elementary students with the way a computer operates and the way people communicate with computers. The format of the unit was designed so that the instruction can be provided by the classroom teacher. The lessons are constructed so that, with some teacher guidance, the students can work through them step by step.…

This series of units is designed to help middle, junior high, and high school students use LOGO computer language as a tool to explore concepts in geometry, estimation and problem solving. The format of the unit was designed so that the instruction can be provided by the classroom teacher. The lessons are constructed so that, with some teacher…

Describes experiences with turtle graphics to demonstrate motion in a constant gravitational field. Provides the computer program and typical diagrams. (YP)

Describes mathematical problems which occur when using the computer as a calculator. Considers errors in BASIC calculation and the order of mathematical operations. Identifies errors in spreadsheet and calculator programs. Comments on sorting programs and provides a source for Mathemagical Black Holes. (MVL)

Described is a short program for teaching and learning about geometric transformations. The integration of geometry problem solving and BASIC programing is discussed. Applications of computer graphics are illustrated. (CW)

Discusses the golden ratio and how to make golden triangles using recursive Logo programs. Presents some outputs of the Penrose tile patterns. (YP)

Provides a listing of a software graphics program that investigates the law of reflection and Snell's law of refraction. Written in BASIC for the Apple II personal computer. (MVL)

Offers several LOGO programs to study the behavior of simple nonlinear systems. Suggests that LOGO is an excellent tool for studying chaotic systems. Offers suggestions for different forms of LOGO. Builds upon programs presented in a previous article. (MVL)

Developed as an introduction to computer programming using an Apple microcomputer, this document presents teachers and students with: (1) essential vocabulary used in the BASIC language; (2) syntax; and (3) programming techniques. Simple hands-on activities designed to guide the learner through beginning BASIC programming skills and fundamental…

Turtle graphics is a popular vehicle for introducing children to computer programming. Children combine simple graphic commands to get a display screen cursor (called a turtle) to draw designs on the screen. The purpose of this study was to examine young children's abilities to function in a simple computer programming environment. Four- and…

Presents a computer program which prints out a calendar corresponding to any year A.D. and states the objectives for such a program. Shows an example of a sample run. (RT)
