The use of Logo to develop mathematical concepts is advocated. Children's comments as they work with Logo are presented. (MNS)

A program for a number of guessing logic games, written in APPLESOFT, is first given. Then four computer-related terms are defined. (MNS)

We expand the theoretical perspective based on the notions of description and conflict, which was previously used to the learning of functions and calculus, to the learning of deductive geometry supported by Dynamic Geometry (DG) environments. Based on prior studies on functions and on the potential role of a DG software, we analyze a case study…

In this paper, the theory of variation in the tradition of phenomenographic research approach is placed in the context of Dynamic Geometry Environment (DGE). Central concepts of discernment, variation, simultaneity and space of learning in the theory of variation are discussed for simple dragging episodes in DGE to illustrate the potential…

The process of learning cooperatively improves the acquisition and retention of content and skills throughout the curriculum. This booklet provides information and tips on the use of cooperative learning in the classroom and how technology can be helpful. Tips for groupmaking, self-allocating roles, complementary information, conflicting…

The concept of trigonometric ratios in a right triangle can be clearly presented through the use of interactive-geometry software. Investigation in this manner allows students to see the crucial features of the concepts before they are formalized and to gain ownership of these ideas through discovery. Many examples of the mathematical…

Demonstrates the use of scientific visualization, a computer graphics technology developed to extend the use of our visual system to contexts and problem-solving situations where sight itself is not directly possible or in which normal vision fails to provide adequate opportunity for analysis. (DDR)

Presents a method for using matrix algebra and computers to encode and decode secret messages. Provides examples of coding procedures, a short review of matrix multiplication, and a BASIC program for use with secret messages containing up to 1000 numbers. (RT)

Suggests computer graphing as a topic for computer programing. Reviews Apple II computer graphics information and gives suggestions for writing the programs. Presents equations to help place information onto the screen with proper coordinates. (MVL)

At the University of Arizona, institutionally-developed software is used in electronic classrooms in some mathematics courses. Students like the software, and faculty find it helps their teaching by making skill development easier and giving students a new appreciation for the subjects. The programs are distributed free to other campuses and…

Explores abundant numbers and presents a proof that abundant numbers of every order exist. Readers are encouraged to use the included computer program to explore abundant numbers for themselves, look for patterns in the output, and consider further questions. (Author/MKR)

Six male elementary school students with learning disabilities were taught multiplication facts using a computer software program with a five-second constant time delay procedure. Results indicated that the computer-assisted instructional program was effective. Learning generalized with varying degrees of success. (Author/JDD)

Shows a way in which algebra and geometry can be used together to find the lengths and areas of spirals. This method develops better understanding of shapes, similarity, and mathematical connections in students. Discusses spirals embedded in triangles and squares, the Pythagorean theorem, and the area of regular polygons. (MKR)

Discusses the value of student-designed, in-depth, modeling projects in a differential equations course and how to prepare students. Provides excerpts from worksheets, a list of computer software for Macintosh that can be used in teaching differential equations, and an annotated bibliography. (Author/ASK)

Describes an educational software program for the study of and detection methods for the cosmic ray muons passing through several light transparent materials (i.e., water, air, etc.). Simulates muons and Cherenkov photons' paths and interactions and visualizes/animates them on the computer screen using Monte Carlo methods/techniques which employ…
