Presents seven computer-oriented activities. Although some of the activities assume a certain level of computer expertise, all of them can be easily adapted for students in any grade. Activity topics include electronic geoboard, codes/coding, probing problems, looping, metrics, Logo databases, and writing Cinquain poetry. Program listings are…

This book helps individuals use Turtle Time Designs programs (i.e., a series of graphics program files to be used with LogoWriter) even if they have little previous experience with LogoWriter. The features of each program are carefully explained and are followed by step-by-step suggestions for teaching the lesson. Examples of the types of designs…

Offers suggestions for five computer-oriented classroom activities. They include uniting a writing class by having them collectively write a book using a word processor, examining FOR/NEXT loops, using a compound interest computer program, and developing a list of facts about computers. Includes four short programs which erase monitor screens. (JN)

Explores the use of computers for teaching mathematical models of transposition ciphers. Illustrates the ideas, includes activities and extensions, provides a mathematical model and includes computer programs to implement these topics. (MVL)

A questionnaire that college economics students can use to investigate the degree and nature of competition in the retail market for petrol is provided. A simple computer program is included to help in the analysis of the questionnaire. (Author/RM)

An activity that shows how mathematics can be used to model events in the real world is described. A way to calculate the area of the sun covered by the moon during a partial eclipse is presented. A computer program that will determine the coverage percentage is also included. (KR)

This computer software is a tool designed to help teachers help children in grades 1 through 7 construct their own knowledge of whole numbers and fractions. This software is the first in a series of new, dynamic computer microworlds that allow teachers to interact with students and students to interact with each other as they engage in…

Suggests having students design a football field (looking at it from above) as the final project of a unit on computer graphics. Includes listings for 13 short Applesoft programs (involving LO- and HI-RES graphics) which students can use in making the field. Advanced students can use the animation techniques. (JN)

Described are activities in the study of techniques used to conceal the meanings of messages and data. Some background information and two BASIC programs that illustrate the algorithms used in a new cryptographic system called "public-key cryptography" are included. (CW)

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)

Provides specific directions and guidelines for the computer program "YOU Program ME." Explains how this introductory hands-on activity can teach the concept of programming and can introduce the BASIC language. Background information and student activity sheets are included. (ML)

Described is a strategy that allows students to experiment with probability without applying formulas to solve problems. Students are able to intuitively develop concepts of probability before formal definitions and properties. Sample problems are included along with BASIC programs for some of the problems. (KR)

Presents the Morris Loe Angle Trisection Approximation Method to introduce students to areas of mathematics where approximations are used when exact answers are difficult or impossible to obtain. Examines the accuracy of the method using the laws of sines and cosines and a BASIC computer program that is provided. (MDH)

Describes the method for producing the equiangular spiral, the geometric curve generated by modeling an insect's orientation process to an illumination source, utilizing a LOGO Turtle program which is included. (JJK)

Explores the close relationship between pattern formation and traditional geometry using the LOGO programing language with the specific example of joining squares, corner to corner, to form a closed ring. Includes the LOGO programs utilized, as well as color illustrations of the interesting and eye-catching patterns generated. (JJK)
