Outlines two experiments by which several different mathematical topics can be integrated into the unifying theme of oscillating pendulums, as part of a secondary school Algebra II and Trigonometry class. (CS)

Provides computer programs (for Apple microcomputers) for drawing (in high resolution graphics) a three-leaved rose, concentric circles, circumscribed and inscribed astroids. Sample output and discussions of the mathematics involved in the programs are included. (JN)

Describes an instructional strategy to convey the elements of trigonometry to introductory physics students. (SK)

Describes how to measure animals pace, stride, and step angle in degrees. Presents cases of measurements for dinosaur trackways. (YP)

This paper presents a laboratory exercise in which an integration problem is applied to cinematography, without the need for apparatus. The problem situation is about the oscillation control of a camera platform to attain the contrast angular rate of objects. Wave equations for describing the oscillations are presented and an expression for…

Arguing that high attrition rates and low grades in trigonometry classes underscore the need for changes in the approach to trigonometry instruction, these papers suggest an instructional model and present a proposal for its adoption at the College of San Mateo (CSM). The first paper begins with the argument that students' lack of preparation for…

Two teachers share practical tips for teaching secondary school mathematics. The tips focus on effective use of homework and teaching trigonometric concepts. (PK)

This report examines mathematical graphing utilities or function plotters for use in introductory algebra classes of more advanced courses. Each product selected for inclusion in this report is able to construct the graph of a given equation on the screen and serves as a utility which may be used by the student for an open-ended exploration of a…
