Provided is a review of an educational software program called "Delta Drawing." Included are comments on how the graphics program works, programing features, comparison with LOGO, educational value, and availability. Indicates that as a powerful learning program, it is innovative and imaginative. (JN)

Discusses how to use vector graphics programming on Apple microcomputers for creating animation. Secondary school students with programming experience should be able to master the essentials of the two-stage technique, especially if they have already worked with LOGO graphics. (JN)

Learning how to create smooth animation on the computer is a two-step process. Step one (discussed in SE 539 133) involves creating shapes. In the second step, students animate their newly created shapes. The programing necessary to accomplish the animation is discussed. (JN)

Discusses various aspects, features, and uses of the Logo programing language. A comparison (in chart format) of several Logo languages is also included, providing comments on the language as well as producer, current price, number of sprites and turtles, computer needed, and whether debugging aids and list operations are included. (JN)

Presents activities and program listings to print ASCII characters, examine the "IF" command (Pascal), change colors of a word on the screen (Atari), and to create a drawing tool for making designs (Logo). Also presents an activity on dummy sorting. (JN)

Describes activities designed to teach students about embedded recursion. Topics cover providing intuitions about embedded recursions, predicting embedded recursions, seeing patterns and processes, presenting graphic designs containing embedded copies of themselves, and exploring graphics, numerical, and word examples. Parts I and II are in…

Discusses activities for counting using FOR/NEXT commands, finding number of letters in words using LOGO, generating random numbers on the TRS-80 (program listing included), and examining mistaken predictions. Includes the article "Animating Graphics in BASIC" by Ellen Joslin (program listing included). (JN)

Discusses a computer program which converts TRS-80 programs into Applesoft Basic. Although the complete program is listed, a disk containing the binary files necessary for the conversions is available (current cost $10.00) from the author. (Author/JN)

Arguing that mathematics is a form of communication that students need help in understanding, this article describes a set of seven simple interactive LogoWriter tools that can be used to help children explore the language of multiplication. Examples of the use of graphics in responding to children's commands are provided and several exercises are…

Interactive computer graphics is fast becoming the standard medium of communication between computers and all kinds of users. Reasons for this trend, the technology of interactive graphics displays, software considerations, applications (including classroom and laboratory applications), and future developments are discussed. (JN)

Relates experiences of an elementary school reading teacher and a group of fifth- and sixth-grade students in exploring the computer programing language Logo. Use of a tree-like figure as an illustration for the concept of recursion is described. Programing commands and graphic illustrations are included. (EJS)

Provides Logo activities designed for adults and children to use together. Although activities are designed for Terrapin/Krell Logo, modifications are provided for use with Apple Logo or TI Logo (Texas Instruments). "Bugs" are introduced in one activity to demonstrate how they can lead to unexpected results. (JN)

This paper investigated three kinds of changes that could occur when a child learns to program in Logo. Novice programmers from fourth grade classes were given three sessions of Logo instruction. Results provided some preliminary evidence that productive learning of a programming language involves a chain of cognitive changes. (Author/LMO)

Five guidelines for enhancing the value of a computer graphics program are described and illustrated. Using a well-structured program, correct scaling, normalized device coordinates, word coordinates, and illusions are discussed. (MNS)

Presents six computer-oriented classroom activities. They include: surveying a house for products using microprocessors, writing a program to display a flag, experimenting with LOGO's graphics capabilities, writing stories on the computer, using FOR/NEXT commands to create a blinking object, and teaching the Milton Bradley Big Trak to play…
