Introduction to Programming Using Terrapin Logo for the Macintosh

Abstract

This manual has a dual purpose: to teach about programming in the Logo language for teachers, and to teach Logo in a structured manner to students. The publication is divided into 41 sections, each of which focuses on a particular Logo word or idea, and is designed to give both teachers and students the opportunity to experiment with ideas while extending their knowledge of Logo. Some of the subjects covered in the individual chapters include: (1) getting started with Logo for the Macintosh computer; (2) using the Repeat function; (3) shapes and STAMP; (4) defining new shapes, putting text on the screen, and mixing text and graphics; (5) writing procedures; (6) designing programs; (7) managing workspace and files; (8) using pen modes, windows, and multiple turtles; (9) Logo grammar; (10) animation, creating definite loops, stamping areas, interactive programming, and working with files; (11) procedure inputs; (12) Logo arithmetic and mathematics; (13) outputs; and (14) useful graphics and text reporters. Most of the chapters provide tips and techniques as well as project suggestions. It is suggested that the examples in each chapter be experimented with until the concept being introduced is understood. A quick reference card of all the Terrapin Logo primitives is provided at the end of the manual, and major subject areas and Logo commands are listed in the index. (DB)
