Provides instructions and rules for a game to teach covalent bonding in which a set of plastic atoms are combined to produce stable covalent bonds. (DS)

Briefly describes the application of thermodynamics (system at equilibrium) to the study of the extraction of metals from their oxides (dynamic situation). It is more relevant to study the temperature variation of the equilibrium constants of the reaction than to study the free energy approach. (Author/SK)

Suggests ways in which chemistry professionals, particularly academic faculty members, might improve the image of chemistry and engineering. Stresses damage done to this image because of recent media coverage regarding misuse and improper disposal of chemicals. (CS)

Discusses how modern mathematical language can be used to develop chemical ideas in class. Examples for the application of Venn Diagrams and Flow Diagrams in teaching chemistry in the Nuffield courses are presented. (HM)

Describes a study of currently available introductory chemistry textbooks for nonchemistry majors. Investigators (one philosopher and one chemist) read books and noted instances of value judgments and content. Findings include uniformity in factual content, and an abundance of value judgments on social, political, and economic issues. (DS)

A questionnaire was administered to first-year biology, physics and chemistry students in an Israeli university to assess their views on the nature of the contribution made by their high school courses to college achievement. Results indicate that high school curriculum influences attitudes, knowledge retention, expectations, and achievement in…

Freshmen college students (N=290) were asked, "What is an atomic orbital?" as a measure of their knowledge after completing high school chemistry. Results suggest that high school chemistry be divided into two levels: (1) procedures and interpretations of classical chemistry and (2) introduction of elementary quantum chemical concepts.…

Illustrates common mistakes teachers usually make when discussing physical phenomena. Presents correct and incorrect explanations for five common science demonstrations. (SK)

Examines whether retesting: (1) affects achievement of students (N=95) grouped according to previous achievement in science; and (2) influences students to delay studying and perform at a low level on initial tests. Also examines whether procrastination of retested students is affected by their achievement level. (DS)

Discusses analytical methods selected from current research articles. Groups information by topics of general interest, including acids, aldehydes and ketones, nitro compounds, phenols, and thiols. Cites 97 references. (CS)

Reviews technical aspects of structure determination in biological electron microscopy (EM). Discusses low dose EM, low temperature microscopy, electron energy loss spectra, determination of mass or molecular weight, and EM of labeled systems. Cites 34 references. (CS)

Presents tables which list books, reviews, conferences, and proceedings that are of interest in the field of nucleonics. Also provides information on SI units. Cites 232 references. (CS)

Covers recent developments in ultraviolet and light absorption spectrometry. Subject matter is divided into sections on chemistry, physics, and applications. Cites 655 references. (CS)

Outlines a five-week chemistry program designed by university faculty for junior high students with a strong interest in science. (CS)

Describes and evaluates the fabrication of an easily constructed and inexpensive stop-flow system using commercially available components. (CS)
