Discussed are three themes related to changes taking place in secondary school education in Great Britain. The themes considered are curriculum, assessment, and school organization. (RH)

Provides examples of several ways that humor may be used in the physics classroom. Included are the use of cartoons, puns, visual puns, unusual units of measurement, scientific errors which have amusing consequences, posters, and amusing problem sets. (CS)

Describes an approach to titration curves which eliminates the choice of approximations and the algebraic complexity of accurately solving for hydrogen ion concentration. This technique regards moles of titrant as the dependent variable. (CS)

Provides an explanation for the apparent emission of x-rays from video display terminals. (CS)

Lists alphabetically by author the articles, notes and letters published in Volume 18 of the "Physics Teacher." (CS)

Describes a system of heuristics for problem solving and instructional methods for presenting it to secondary school students. (CS)

Reviews properties, geologic occurrences, availability to plants, and cycles of the element selenium. (CS)

An annotated list (books, magazines, and media) of sources of free and inexpensive science materials is provided, including addresses and costs (if any). (SK)

Provides a brief history of electrets and describes how they can be made in a small laboratory. Also summarizes the uses of electrets and suggests projects and experiments with them. (CS)

Describes the construction of an apparatus that demonstrates that electrostatic forces can be large and also gives some idea of dependence of electrostatic forces between charged parallel discs on potential differences and separation. (CS)

This information packet on quasars consists of an introductory paper, four articles from "Mercury," a journal of the Astronomical Society of the Pacific, and a bibliography. Methods used to measure distances in the universe and the nature of quasi-stellar objects (QSO's), the name preferred by many workers in the field, are discussed in…

The purpose of this document is to identify potentially hazardous substances that may be in use in many school laboratories and to provide an inventory of these substances so that science teachers may take the initiative in providing for the proper storage, handling, use, and if warranted, removal of hazardous materials. The document consists of…

Reviews basic information on the Chemistry of strontium and its compounds. Explains biological aspects of strontium and its pharmaceutical applications. Highlights industrial application of strontium and its components. (ML)

Discusses several aspects of software evaluation, suggesting that software should fit into an existing course and that students and faculty colleagues should be involved in the evaluation process. Also provides sources of evaluation guides, actual educational software evaluations, and software awareness materials. (JN)

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)
