Functional programming, in which the connection to mathematics is simple and direct, is described. A language such as Logo illustrates the relationship between functional programming and mathematics in more detail. (MNS)

Describes a program written for a programmable pocket calculator that computes the frequency response of linear systems. (Author)

Discussion of the use of computers in math instruction highlights two possibilities suggested in response to an earlier journal column: (1) a program written in BASIC for producing spirolaterals, and (2) the use of LOGO list processing to solve matrix problems for exploring geometric transformations. (LRW)

Revised material from earlier Project Solo newsletters is presented here. The revised material updates programs to explain the law of sines and cosines and to apply the idea of rectangular coordinates approach to aircraft navigation systems such as VORTAC. A brief discussion of the value of off-line as opposed to on-line activity is also…

Ideas for computer use are presented. A challenge problem, sources of information, and interesting facts are included. (MNS)

Presented are ideas for teaching mathematics with a microcomputer. Ideas include using Apple II Logo to help select students for activities (Wheel of Fortune) and activities to explore how the programming operates. (RH)

Microcomputer programs that help students calculate permutations and combinations are developed. Listings of five programs are included. (MNS)

Two graphics programs for students in grades six-12 are given. "Circle Through 3 Points" and "Star Polygons." Students gain familiarity with the xy-plane, the radii and centers of circles, and ellipses, while more advanced students learn about parametric equations and using random numbers to produce random shapes. (MNS)

The progression from simple interest to compound interest leads naturally and quickly to the number e, involving mathematical discovery learning through writing programs. Several programs are given, with suggestions for a teaching sequence. (MNS)

Using Logo to work through a maze is described. Suggested programs to help students learn to debug programs are also included, along with the story of the original "computer bug." (MNS)

Using Logo as a companion language to BASIC is suggested. Variations on a computer program on squares are given, with follow-up activities suggested. (MNS)

Computer activities involving counting are described along with brief computer programs. (MNS)

A new mathematics curriculum was used in this study which depended fundamentally on the use of computers and programing for presentation. The main part of the research was done with seventh grade children utilizing a programing language, LOGO, specifically designed for the teaching of mathematics. An investigation was also conducted with a group…

Three Project Solo modules are presented. They are designed to teach the concepts of elementary matrix operation, matrix multiplication, and finite-state automata. Together with the module on communication matrices from Newsletter #17 they form a well motivated but structured path to expertise in this area. (JY)

Exploratory study aimed to investigate elements of geometrical concepts that children learn through Logo programing. A test designed to assess three components of length and angle was administered to 84 children who had learned Logo for one year and 92 who had not. Data indicated a positive effect of Logo work on some items, but not all.…
