A previously developed program for the HP-41C programmable calculator is extended to handle models of differential and difference equations with multiple eigenvalues. How to obtain difference equation solutions via the Z transform is described. (MNS)

Presented is a program written for an HP-25 programmable calculator. It will aid in the effective impedance of a series-parallel network containing both reactive and resistive elements. (MNS)

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

Discusses numerical methods to compute approximate solutions of a differential equation. Provides a Pascal program for the extended Euler-Heun method. (YP)

Several examples are given of a variety of nonstandard problems, not ordinarily found in texts or courses, now accessible to students who have programmable calculators. These include: (1) finding limits; (2) evaluating infinite series; (3) calculating finite series; (4) computing variable length products; (5) solving equations; (6) searching for…

Strategies for incorporating a calculator made within FORTRAN programs and a Response Analysis Scheme during interactive sessions are described highlighting salient features of the programs. (Author/SK)

Suggests two uses for the programmable calculator in the freshman chemistry laboratory: as a means of determining whether or not a student's raw data from a laboratory experiment fall within acceptable tolerance limits; and as a means of checking the reliability of unknowns and grading on quantitative experiments. (MLH)

Describes six crystallographic programs which have been developed to illustrate the range of usefulness of programmable calculators in providing computational assistance in chemical analysis. These programs are suitable for the analysis of x-ray diffraction data in the laboratory by students. (HM)

This paper merges state-of-the-art calculator technology with examples drawn from the Harvard Consortium Calculus Curriculum. A brief rationale for selection of the Harvard project and the TI-85 is provided, and four different mathematical situations are examined using different capabilities of the TI-85. Two short TI-85 programs are given.…

Discusses the use of graphing calculators for polar and parametric equations. Presents eight lines of the program for the graph of a parametric equation and 11 lines of the program for a graph of a polar equation. Illustrates the application of the programs for planetary motion and free-fall motion. (YP)

This Texas Tech University computer literacy course designed for preservice elementary and middle school mathematics teachers lacking a technological orientation facilitates their computer introduction through preliminary use of calculators. Course development, philosophy, and course segments are outlined with emphasis on the sequence in which…

Presented are exercises that demonstrate the application of standard concepts in the design of algorithms for plotting certain fractals. The exercises can be used in any course that explains the concepts of bounded or unbounded planar sets and may serve as an application in a course on complex analysis. (KR)

This book attempts to introduce students to the creative aspects of mathematics through exploratory problems. The introduction presents the criteria for the selection of the problems in the book. Criteria indicate that problems should: be immediately attractive, require data to be generated or gathered, appeal to students from junior high school…

Eighteen papers on instructional technology, computerized testing, and computer assisted test construction (CATC) presented at the 1976 Association for Educational Data Systems (AEDS) convention are included here. Two papers discuss computer assisted instruction in calculus and teacher education courses. The use of computers in theoretical…
