Provides author and subject indexes for material appearing in "The Physics Teacher" during the years 1963 to 1980. Subject index is arranged alphabetically by major and minor topic areas. (JN)

Describes 17 situations in physics which require students to write computer programs to solve. All the projects are general in nature and require students to have a thorough conceptual understanding of the content to apply the algorithm needed to solve the specific type of problem illustrated. (JN)

Presents the listing (TRS-80) for a computer program which derives the relativistic equation (employing as a model the concept of a moving clock which emits photons at regular intervals) and calculates transformations of time, mass, and length with increasing velocities (Einstein-Lorentz transformations). (JN)

Describes three computer programs which operate on Apple II+ microcomputers: (1) a menu-driven graph drawing program; (2) a simulation of the Millikan oil drop experiment; and (3) a program used to study the half-life of silver. (Instructions for obtaining the programs from the author are included.) (JN)

Describes (1) use of VELA (a stand-alone programmable instrument); (2) forced harmonic motion of galvanometers; (3) holographic interferometry and measurement of small angular displacement; and (4) an analogy useful on teaching capacitors at A-level. Also describes a comparison of fuses and circuit breakers using a microcomputer as a storage…

Presents a system that permits students to engage directly in the process of modelling and to learn some important lessons about models and classes of models. The system described currently runs on RML 380Z and 480Z, Apple II and IIe, and BBC model B microcomputers. (JN)

Discusses graviperception and gravitropism by plant roots. Indicates that graviperception occurs via sedimentation of amyloplasts in columella cells of the root cap and that the minimal graviresponsiveness of lateral roots may be due to the intensity of their caps to establish a concentration gradient of inhibitor(s) sufficient to affect…

Suggests that a broad and balanced science education for all up to 16+ is a good thing, that it should be built from the bottom up, be differentiated to accomodate all abilities, and contain within it core streams in the general fields of biology, chemistry, and physics. (JN)

Discusses the Certificate of Secondary Education (CSE) physics examination. Areas addressed include CSE personnel, setting and moderating papers, marking and standardization, grading, curriculum development, and the examination profession. (JN)

Describes how microcomputers can perform very demanding/large-scale physics calculations at speeds not much slower than those of modern, full-size computers. Among the examples provided are a Monte Carlo simulation of the three-dimensional Ising model and a program (for the Apple microcomputer) using the time-independent Schrodinger Equation. (JN)

Discusses need for introducing material to educate students about the relationship of philosophy to physics and science in general, particularly in light of quantum mechanics. Suggesting the dual nature of electrons as a starting point and citing several supplemental texts, a demonstration is described to be used to introduce the topic. (JM)

Many people erroneously believe that an object carried by another moving object will, if dropped, fall in a straight vertical line. This belief may stem from a perceptual illusion in which objects dropped from a moving carrier are perceived as falling straight down or even backward. (Author/RD)

Describes a variety of laboratory experiments including carbon dioxide reduction, animal respiration, atmospheric pressure determination, and others, that can be performed using discarded syringes. (GS)

Compares curriculum project adoption figures derived from examination entries with figures derived from questionnaires in an attempt to place the questionnaire returns in perspective and give an indication of the confidence which may be placed in them. (GS)

Discusses ten methods for measuring the thermal expansion of solids and the way in which the expansion coefficient relates to other properties of matter. (MLH)
