Described is the use of computer software, with and without guiding text, for a simulation that presents processes related to electric charges and electric forces underlying the electric-pendulum phenomenon. Included are methods for integrating this simulation with actual middle-school science class demonstration. (JJK)

Provides a program listing in True BASIC which constructs several kinds of matrices: (1) matrices with integral entries that have inverses that have integral entries; (2) matrices with integral entries that have inverses that are rational numbers with reasonable denominators; and (3) matrices with integral entries and prescribed integer…

Compares a program written both in BASIC and LOGO on its inferential and decision making ability. Explains steps in each program and how deductions and decisions are made. (MVL)

Describes mathematical problems which occur when using the computer as a calculator. Considers errors in BASIC calculation and the order of mathematical operations. Identifies errors in spreadsheet and calculator programs. Comments on sorting programs and provides a source for Mathemagical Black Holes. (MVL)

Describes the titration of a weak base with a strong acid and subsequent treatment of experimental data using commercially available software. Provides a BASIC program for determining first and second derivatives of data input. Lists 6 references. (YP)

Examined is the use of the microcomputer as a tutor, for simulations of experiments, and to provide graphic interpretations of abstract concepts in the college biology setting. Discussed are computer enhanced courses being used, the software library, and the computer laboratory facility. Lists reasons for adoption of computer enhanced format. (MVL)

Described is a learning activity which incorporates computer programing and the teaching of arrays. Using the newspaper as a source for ideas for programing assignments and classroom examples is emphasized. (KR)

Presented are several simple kinetic systems together with the spreadsheets used to solve them. A set of exercises in chemical kinetics appropriate for an introductory course in physical chemistry is given. Error propagation calculations with experimental data are illustrated. (CW)

Presented are some current facts about symbol manipulators and their relation to high school mathematics. The development of computer algebra systems is discussed. Five areas of computer algebra needing investigation (skill proficiency, understanding, curriculum content, student homework, and equity) are identified. (MVL)

Describes a program to improve computer expertise, encourage science teachers to use computers in science and technology, and to develop computer methods to enhance student achievement and understanding. Discusses participant selection, a summer institute, followup activities, and a network system. (MVL)

Describes the preparation of preservice secondary mathematics teachers in the uses and implications of classroom technology. Presents four areas of technology: (1) programing; (2) utility programs; (3) calculators; and (4) implementation of instructional software and communication packages. (Author/YP)
