WebTOP is a three-dimensional, Web-based, interactive computer graphics system that helps instructors teach and students learn about waves and optics. Current subject areas include waves, geometrical optics, reflection and refraction, polarization, interference, diffraction, lasers, and scattering. Some of the topics covered are suited for…

Described is a physical pendulum experiment with variable pivot as an example of maximizing computer benefits in laboratory interfacing. The laboratory procedures using spreadsheet graphics package are discussed. A diagram of the pendulum, basic formulas, and theoretical curve is provided. (YP)

Emphasizes two aspects for a calculus-based physics course: applying calculus and numerical integral methods to determine the theoretical period of a pendulum with nonlinear motion, and achieving theoretical and experimental results by using "MathCad" software and a microcomputer-based laboratory (MBL) system.

Although technological innovations have the capability to significantly change how scientific investigations are done and greatly enhance the teaching and learning of science, its use is no more effective than any other resource or innovation when researched-based effective teaching practices are not followed. This paper reviews established…
