Describes the design of an experiment that is used to determine the acceleration of an accelerating system with the help of an airtrack and a pendulum. (GA)

Gives an explanation to the process of charging the conventional leaf electroscope, by induction, using a charged insulated rod. (GA)

Describes the following: a device which converts the displacement of a pendulum into an electric signal and is used as a voltage generator of low frequencies; a turn-by-turn transformer demonstration; how to remove the buoyant force on a piece of cork immersed in water; and how to demonstrate Coulomb's Law on the overhead projector. (GA)

Briefly assesses the state of physics education over the past 50 years, and explains what is believed to be the necessary direction that should be taken in the immediate future. (GA)

Gives a brief biography of Homer L. Dodge the scientist, educator, and adventurer by looking at his diverse activities, interests, philosophy and accomplishments over a life span of over 90 years. (GA)

Describes six physics courses, at two universities, with career-linked applications offered as electives and designed to strengthen interests in physics and help in career preparations of nonscience students. (GA)

Discusses one of the newest methods used to probe the upper atmosphere using naturally generated infrasound from ocean waves. (GA)

Describes how to measure Brewster's angle using Polaroid sunglasses and the reflection of the ceiling light on a polished floor. (GA)

Explains a flexible two-part grading scheme which attempts to mix the best of both the descriptive and analytical treatments of an introductory astronomy course, to allow for differences in the academic backgrounds of the students. (GA)

Checks on the logarithmic property of the eye in receiving light, by using estimation methods of how much brighter a light bulb looks than does its image in a window glass. (GA)

Describes a demonstration that shows induction, emf, and the right-hand rules, using two solenoids, two strong bar magnets, and two small masses. (GA)

Describes demonstrations used by the nineteenth century physicists to determine if two bodies oscillating at the same acoustic frequency were in phase. (GA)

Describes a new physics program which depends mainly on student performed experiments and investigations, and subscribes to Piaget's learning and developmental theories. (GA)

Describes how an astronomy course, designed for nonscience students, was structured, taught, and graded, pointing to specific changes made with respect to the individualizing aspect of the procedure. (GA)

Describes the criteria used to devise a test to evaluate the experiment-oriented investigative and problem-solving capabilities of students entering an introductory physics course. (Author/GA)
