Updates the results of a six-year experimental course in physics whose goal was to translate the physicist's approach to science into an approach to the teaching of physics. Provides a course description and rationale and outlines the instructional procedures used. (GS)

Describes how teachers can use wheels of tricycles, bicycles, and trains to stimulate children with mathematics, relative position, and engineering concepts. Techniques are offered for measuring circumference of a bicycle wheel, gear ratios, and pedal wheel circumferences. Comparative data are given for various sized wheels. (Author/SA)

Describes a project on the application of the laser which aims to stimulate the interest of undergraduate students in applied physics and to demonstrate the interaction between light and ultrasonic waves by building a simple laser communication system. (SK)

Describes a straightforward vertical fall experiment using a badminton shuttlecock, a tape measure, and a millisecond timer. The effects of air resistance are important and directly measurable. The experimental data best fit a predictive model which assumes a resistive force quadratic in the instantaneous speed of the falling object. (GS)

Describes the history, activities, and accomplishments of the American Association of Physics Teachers, including assuming many responsibilities of the former Commission on College Physics. (JN)

Describes a method for students to evaluate and experience a repetition of important physics concepts during regular lecture sessions. The major goal was to train students to focus attention on course materials. (SK)

Reviews the history, nomenclature, theoretical background, and construction of batteries. Compares the performance of different battery types. (JN)

The study investigated specific student behavior in introductory and advanced college laboratories in botany, chemistry, geology, physics, and zoology. Behaviors were observed, described, and classified with no effort made to induce change, detail underlying conditions, or identify correlates. (Author/RE)

Discusses a method used at DePaul University of Chicago, Illinois, in a relativity course for students who are not science majors, emphasizing logical reasoning rather than memory of facts. (HM)

Discusses how the frequency domain (line widths) and time domain (coherent optical transients) are related to the concept of transverse relaxation time in the study of high resolution optical spectroscopy. (HM)

Presents the first of a series of articles that discuss the perception of sound and music. This series of articles is intended to provide an introduction to the broad subject of high-fidelity sound recording and reproduction. (HM)

Describes the status of teaching physics at Xaverian High School, Brooklyn, New York. The enrollment of students in physics, instructional materials, laboratory activities, and coordination between physics and mathematics are described. (HM)

Investigates some conceptual difficulties which college students have with regard to simple direct current circuits. The clinical interview technique was used with 57 students in a freshman level engineering course. (HM)

Discusses the increasing role of the physicist in plastics technology. Relationships of molecular structure to material behavior, design which is related to the material, and the practical problems of fabricating a material into an article are included. (HM)

Describes a simple apparatus for producing strip holograms with a number of slit-shaped exposures displaced along the vertical direction. The hologram maintains full horizontal parallax, but the slit aperture reduces the vertical viewing angle of the animated object. (Author/GA)
