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)

Described is a research-based instructional technique for teaching analogical reasoning by the use of guided LOGO programing activities. An example worksheet is provided illustrating the use of the Sternberg's four-step analogical reasoning technique (encode, infer, map, and apply) with LOGO programs. (Author/MDH)

This document combines a students' manual and a manual for teachers. The students' manual is a self-teaching guided discovery manual for junior high, high school, and college students that provides self-paced explorations into recursion. It includes a disk with lessons that are to be used with the written material. There are eight lessons…

Offers examples of loss of accuracy when using digital computing devices. Discusses causes for loss of accuracy and methods of preventing loss. Presents implications that loss of accuracy has for mathematics instruction. (MDH)

This program offers a collection of interactive lessons and examples designed to help students learn to spell 2000 words. The program's multimedia tutorial style provides a challenging and enjoyable way to improve spelling skills. In the quizzes, exercises, and games in the program, the student can both hear how the words are pronounced and see…

Describes the derivation of the parameters incorporated into computer programs that are utilized to draw hypocycloids, which are the loci of points traced out by a point on a disk as it rolls against a circle and its interior. Includes information to obtain copies of the programs described. (JJK)

Describes the processes involved in leading students from the basics of MaxMix courseware to the final investigation. Discusses a mathematical game, number and graphic tasks included in the package, along with invoking meaningful interaction and integration into classroom mathematics. (RT)

Designed to assist chemistry teachers in selecting appropriate software programs, this publication is the sixth in a series of six teacher's guides from Project SERAPHIM, a program sponsored by the National Science Foundation. This guide is keyed to the chapters of the text "Chemistry: The Study of Matter." Program suggestions are…

Examines "Decisions, Decisions-Revolutionary Wars: Choosing Sides," an Apple II software package that emphasizes student decision-making about the nature of revolutions. Targeted at grades 5-12, the product covers a broad range of issues. Concludes that "Decisions, Decisions" models an effective decision-making process and has…

Uses LOGO to enhance the applicability of curve stitching in the mathematics curriculum. Presents the formulas and computer programs for the construction of parabolas, concentric circles, and epicycloids. Diagrams of constructed figures are provided. (MDH)

Uses chaos theory to investigate the nonlinear phenomenon of population growth fluctuation. Illustrates the use of computers and computer programs to make calculations in a nonlinear difference equation system. (MDH)

Discusses essential commands of the BASIC programing language to help secondary school English teachers develop an understanding of the language and enable them to create programs to supplement English lessons. A core program that can be easily modified by teachers for developing a series of programs is described in detail. (MBR)

Described is a LOGO computer program that enables students to investigate the relationship between a digital number and the resistance in a variable resistor used to generate that number. Likewise, actual temperature readings and the corresponding resistance within a thermistor can be used for data gathering and subsequent analysis. (JJK)

Presents a method blending ideas from logic, algebra, and operators to devise discrete functions that yield the same truth values as the truth tables associated with specific logic statements. Introduces mechanisms that encourage students to discover examples of discrete functions, approximately represent logic statements, and provides examples of…

The LOGO subroutine turtle geometry and Euclidean geometry are compared with respect to their treatment of similarity and difference of plane figures. The problem and its proposed solution of introducing a FLIP operation are viewed briefly from the perspectives of mathematics, computer science, and education. (MDH)
