A math teacher recounts how six weeks of computer assisted instruction, about which she had been very skeptical at first, resulted in substantial gains for six learning disabled students in addition, subtraction, multiplication, and division. (CL)

Describes the method to solve problems called T-E-M-T-T: trial, error, and modified trial through technology. The method integrates students' skills of estimation, mental computation, and appropriate choice of calculator use. Includes 2 activities for each of grades K-4 and 5-8 that illustrate the method. (MDH)

This paper advocates the use of symbolic computation packages as another aid in teaching geometry. The need for such packages and their use in computerized proofs are demonstrated by a problem in high school planar geometry. (LZ)

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)

The planning, design, and construction of a computer-assisted instructional program in pharmaceutical calculations at St. John's University College of Pharmacy and Allied Health Professions is reported. The program was designed to supplement classroom teaching by concentrating on problem solving. A sample unit of instruction is appended.…

A method that enables people to obtain the benefits of statistics and probability theory without the shortcomings of conventional methods because it is free of mathematical formulas and is easy to understand and use is described. A resampling technique called the "bootstrap" is discussed in terms of application and development. (KR)

Described is an approach to computational matrix algebra that takes advantage of a high quality, low cost microcomputer software package. The examples and applications discussed focus on matrix multiplication. (Author/CW)

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)

Described is an approach to the derivation of numerical integration formulas. Students develop their own formulas using polynomial interpolation and determine error estimates. The Newton-Cotes formulas and error analysis are reviewed. (KR)

Computing pi efficiently has been of great interest to mathematicians for centuries. This article presents an algorithm to solve this problem through skillful computer use. (PK)

Describes "Kid Cuts," an arts and crafts computer software program for students in prekindergarten through sixth grade that provides 22 activities in 6 curriculum areas. An example is given of an activity for kindergarten and first graders related to counting that includes library media skills objectives and mathematics objectives. (LRW)

This curriculum guide is one of a series of five books published to supply all appropriate information related to the Hewlett-Packard Mathematics Drill and Practice Program for the computer. This text serves as the primary reference source for the program. The content is divided into two sections. A brief explanation of the curriculum structure is…

A model of the phenomenon of the desert mirage is presented using Snell's Law and simple programing techniques. Optical trajectories predicted by the model are illustrated. (CW)

Presented is an experiment where the concentrations of three metal ions in a solution are simultaneously determined by ultraviolet-vis spectroscopy. Availability of the computer program used for statistically analyzing data using a multivariate linear regression is listed. (KR)

Presents standards-based activities that include learning about an electronic card catalog by playing card games; learning to count and to recognize numerical sets by identifying real-life sets (e.g., items in the building or on the playground); and learning about estimation and spatial sense using students and a digital camera.
