Describes several sources of computer programs for secondary school chemistry. Provides an example of a computer package (RANALD I) on quantitative inorganic analysis suitable for O/A-level pupils as a supplement to laboratory work. (DS)

Outlines ideas for units presenting facets of the geographical, economic, social, and cultural heritage of Pennsylvania. Annotated lists of museums, historical resources, suggested field trips, and bibliographies on William Penn and other selected Pennsylvania history topics are included. (AM)

Describes how a reading teacher helped an English class understand a novel set in a different culture using an article from the "Journal of Reading." (AEA)

Discusses the role that radiation-chemical techniques play in the study of the electron transfer process. (CS)

Describes some basic findings in the radiation chemistry of genetic material derived from studies of model systems. Uses these findings to extrapolate the consequences of radiation damage to DNA within cells. (CS)

Discusses the effects of radiation on dividing cells and factors influencing these effects; also briefly reviews the radical mechanism for radiation damage. Emphasizes the importance of oxygen in radiation effects. (CS)

Discusses various aspects of radiation damage to biological material, including free radical mechanisms, radiation sensitization and protection, tumor hypoxia, mechanism of hypoxic cell radiosensitization, redox model for radiation modification, sensitizer probes of cellular radiation targets, pulse radiolysis studies of free radical kinetics,…

Describes common features in the radiation chemistry of food components, and illustrates how product yields are predicted. Presents data that pertain to the radiolysis of the nitrate ion, metmyoglobin, myosin, and tripalmitin. (CS)

These three short articles are designed to help nonmusicians bring musical experiences into their classrooms. The articles discuss teaching resources for the nonmusical teacher; making simple, inexpensive rhythm instruments; and musical games. (Editor/SJL)

Presented are activities and teaching strategies designed to make history real to students, to develop in them, first, a sense of personal involvement with the past, and second, a time-sense and historical perspective. Suggestions include use of biography, historical fiction, oral history, genealogy, role playing, and time-lines. (Author/SJL)

Demonstrates that the Schrodinger equation for the hydrogenlike atom separates in both spheroconal and prolate spheroidal coordinates and that these separations provide a sound theoretical basis for the real and hybrid atomic orbitals. (Author/SK)

Provides instructions for setting up an indoor pond for the elementary school classroom. (CS)

Provides a brief overview of validity and reliability as concepts related to the overall quality of test instruments. Describes the nature and interpretation of content, face, criterion, and construct validity and identifies several approaches for measurement and improvement of reliability. (Author/CS)

Demonstrates how depth of field, exposure correction, and Scheimpflug focusing are obtained for a view camera, using elementary optics. (CS)

Relates science, technology, and education to the current world problem of a declining quality of life. The role of education in solving this problem is explored through a discussion of several curriculum reforms in mathematics, physics, biology, and the "back to basics" movement. (CS)
