Two kinds of secret writing, codes and ciphers, are discussed. The weakness of a ciphering system mentioned in the March 1981 issue is pointed out, and an alternate method is presented. Programs written in BASIC are presented which can be used to encipher messages and help break ciphers. (MP)

The internal operations of this computer symbolic mathematics system are described in detail in order to explain the accomplishments of the computer. (MP)

Problems of designing a college honors program in computer science as an academic discipline are disucssed. (MM)

The use of several features of BASIC programs is examined. Examples of programs and self-tests are included. (MN)

This collection reprints six articles which deal with mathematics and the ways in which computers can help teach even young children about mathematics. The subjects of the articles are: teaching children thinking; teaching children to be mathematicians versus teaching about mathematics; on making a theorem for a child; a computer laboratory for…

This interview reviews Don Knuth's life and contributions and his views on a variety of mathematical and computer-related topics. He is viewed as the pre-eminent scholar of computer science in the world, and is probably best known for a series of books titled, "The Art of Computer Programing." (MP)

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)

This curriculum guide for computer science was developed to establish statewide curriculum standards for the Louisiana Competency-based Education Program. It consists of: (1) a rationale for and overview of the secondary school mathematics program; (2) a list of five suggestions for using the guide; (3) programming, debugging, and documentation…

A formalist approach to the teaching of computer languages in programs leading to associate degrees in computer related technologies is described and advocated. (SD)

A discussion of computer errors and round-offs is given with the conclusion that attempts to get rid of these almost always result in generating more errors. (MN)

Describes various solutions to sequence problems using Logo programing language. Complete program listings are included when applicable. (JN)

LOGO tools are procedures which accomplish specific tasks. They can be furnished to students, along with suggestions for exploratory activities, or students can develop them. Several of these tools (program listings) with sample output are presented. (JN)

The development of symbolic computer algebra designed to manipulate abstract mathematical expressions is discussed. The ability of this software to mimic the standard patterns of human problem solving represents a major advance toward "true" artificial intelligence. (MP)

This 10-chapter book is intended to fill a need for a clearly written, easy to follow, introduction to computer programming that teachers or parents can immediately put to use. Its sample programs are designed to capture attention and spark the imagination of children learning to use computers. The first chapter provides such introductory…
