Variations among different versions of Logo are discussed in terms of special hardware needed, size and speed, bugs and misfeatures, and syntax. LogoWriter and Object Logo are also described. A comparison chart is included. (MNS)

Designed to be an introduction to the Atari microcomputers for beginners, the interactive computer program listed in this document is written in the Pilot programing language. Instructions are given for entering and storing the program in the computer memory for use by students. (MES)

This paper discusses some of the ways one can study graphics on the Apple II microcomputer. Much attention is given to specialized use of software packages used in dumping graphics, and the saving or storing of binary files of graphic images. Knowledge of BASIC at more than a cursory level is required, but a step-by-step procedural outline is…

Discusses the nature and uses of LOGO programing language with primary children. Sample program listings and the results obtained by primary children are included. (JN)

Iteration is the process of doing something repeatedly in a computer program. In LOGO, the most elementary form of iteration is provided by the REPEAT command. This paper explores how programers can use LOGO's extensibility to create more powerful iterative forms than those offered by the REPEAT command. (JN)

Provides examples of nested subroutines, focusing on the Gaussian quadrature function and test program (program listings included). Nested subroutines, features of the Gaussian quadrature, and when not to use it are considered. (JN)

This manual is designed to help classroom teachers in Alberta, Canada implement the Junior High Computer Studies Program. The first eight sections cover the following material: (1) introduction to the teacher resource manual; (2) program rationale and philosophy; (3) general learner expectations; (4) program framework and flexibility; (5) program…

Designed for use by computer programming teachers, this booklet presents the concepts of structured programming and provides examples of how to implement this methodology, which provides a systematic way of organizing programs so that even large and complex programs are easier to understand and modify than unstructured programs. After a brief…

Describes four game programs--Silly Sentence, Spell-It, Scrambled Word, and Guess the Word--designed to introduce elementary school students with no prior programing experience to key concepts of programing with BASIC. Several immediate learning outcomes that became evident while observing students at work with the programs are also discussed.…

This reinforcement activity has been used by students from the elementary school level to the graduate school level who possess intermediate level ability in programming Logo. The activity, which consists of writing Logo programs that animate an object, can have several positive effects as it: (1) helps develop problem-solving skills; (2)…

Discusses how computer-generated music can be used as a starting point to explore the science of sound. Listings for programs which focus on pitch (including a pitch matching game), beat, and frequency are included. (JN)

Discusses how computer programing and expository writing are both based on the ability to (1) recognize that a complex whole is composed of manageable parts, and (2) identify the necessary steps for achieving a goal or supporting a generality, and (3) concentrate on and summarize a large amount of information into an abbreviated, succinct…

Discusses Piaget's pre-operational, concrete operational, and formal operational stages and shows how this information sheds light on how children approach computers and computing, particularly with the LOGO programming language. (JN)

Eight computer-oriented teaching activities are presented. Although all require some computer expertise, they can be easily adapted for students in any grade. Included are various programs using LOGO (drawing insects, fruits, and stars), a LOGO speller, a computer club activities, and others. (JN)

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)
