Discusses several ways in which the Logo programming language can be used to experiment with and learn about matrices. Describes procedures for developing a Logo tool to establish a matrix representation, as well as others for adding, subtracting, and transposing. (TW)

Provides several examples of the use of Logo in working with fractions and manipulating vectors. Includes an exercise which deals with the relationship between the two and several exercises which address various problems using different kinds of fractions. (TW)

Points out the benefits of students using LOGO with problems dealing with vectors and matrices. Provides examples of performing linear algebraic computations in LOGO. (ML)

Described is the history and characteristics of "A Programming Language (APL)." Discussed are how APL facilitates learning the concepts of variable and function and how to get started using APL. Listed are software for schools and 25 references. (Author/YP)

Presents an example of a proof to the mathematical problem of the sum of the cubes of the digits. Provides a Pascal program to search for these results. (MVL)

Presents three activities in which students learn about and construct star polygons using the LOGO programing lanaguage. A list of suggested extension activities is included. (JN)

Notes muMATH is a powerful computer algebra systems assistant for performing symbol manipulation in algebra and calculus. Provides several examples and program listings for calculus tutoring, differentiation drill problems, and integration drill problems. (MVL)

Describes how Logo has been used to introduce primary children to mathematical concepts often considered to be too difficult for them. Outlines how Logo has been used to introduce the estimation of distance, the estimation of angles, symmetry, rules of precedence, the concepts of random, and the use of variables. (TW)

Reports on a study that was designed to investigate possible effects of inservice instruction (BASIC and LOGO/PILOT) on teachers' mathematical anxiety. Results indicated that teachers enrolled in BASIC programing courses manifested more mathematics anxiety after the course than those who were enrolled in a LOGO/PILOT course. (ML)

Described is a short program for teaching and learning about geometric transformations. The integration of geometry problem solving and BASIC programing is discussed. Applications of computer graphics are illustrated. (CW)

Presents abstracts from the National Educational Computing Conference held in Dallas, Texas on June 15-17, 1988. Selected topics include: a physical science interactive videodisc project, impact of calculators and computers in secondary math, relationships between graphing and functions, effectiveness of computer use, training science teachers,…

Discusses dimensionality in Euclidean geometry. Presents methods to produce fractals using LOGO. Uses the idea of self-similarity. Included are program listings and suggested extension activities. (MVL)

Reports on a study designed to further investigate whether structured Logo learning experiences would have a positive influence on student understanding of selected basic geometry concepts. Results indicated more than just one year of Logo instruction would be needed to improve students understanding of simple angle and distance concepts. (TW)

Provides a software program for determining PI to the 15th place after the decimal. Explores the history of determining the value of PI from Archimedes to present computer methods. Investigates Wallis's, Liebniz's, and Buffon's methods. Written for Tandy GW-BASIC (IBM compatible) with 384K. Suggestions for Apple II's are given. (MVL)

Provides an annotated bibliography of references which deal with specific topics for educators using computers in the classroom in teaching mathematics and science. Also appropriate for researchers gathering background material for the preparation of articles, grant proposals, and presentations. (TW)
