Describes an analog computer which serves as a visual aid that calculates the amounts of all substances in an equilibrium mixture as well as during the reaction. (MLH)

Describes two experimental procedures and the reactions suitable for teaching the principle that catalysts do not affect the position of equilibrium. (GS)

Describes the Training in Education for Assistants in Chemistry (TEACH) project, designed to produce materials in several media for improving the teaching of chemistry teaching assistants. (MLH)

Survey shows that 300 full-time academic appointments, 85 percent of which are tenure-track, will be made in 1976-77 in chemistry departments granting advanced degrees. (MLH)

The electrode is a lead dioxide-silver plated wire. Construction of the electrode is simple, straightforward, and provides valuable laboratory experience. (Author/BB)

Discusses how the teacher can deal with difficulties pupils of varying ages have in understanding certain chemical ideas. The article does not support using a Piagetian model for science courses in secondary schools. It suggests that Ausubel's learning theory is of much more use to the practicing teacher. (HM)

Explains using the linear combination of bonding orbitals methods; why two different diagrams are used to represent the molecules when the properties of homonuclear diatomic molecules are being discussed. (GA)

Describes how a high school chemistry teacher runs his classes to prepare students for college. Discusses the examinations routine, the grading system, the laboratory reports, the homework assignments, and the extent of parent participation. (GA)

Describes the results of a study on the use of computer-simulated chemistry experiments. Four different simulated experiments were compared with four comparable laboratory performed experiments. Concludes that simulation has better results and is a good teaching procedure. (GA)

Describes the apparatus used and the experiments performed by a blind student in a freshman analytical chemistry course. (GA)

Reports on a conference of the American Chemical Society in which ways to increase children's interest and exposure to science were discussed. (CP)

Objects to the idea of treating molecular particles, such as molecules and atoms, as equal in kind to substances when discussing chemical reactions, thus confusing their different roles in the theory of matter. (GA)

Argues against the claim that Piaget's theory of formal thought is invalid when used in learning high school chemistry, and suggests a way to test its validity. (GA)

Describes some modifications and rearrangements of topics that were adopted in teaching two units in an advanced chemistry course for high school students: on inorganic chemistry, and on energy and thermodynamics. (GA)

Explains some experiments involving thermal methods of analysis for undergraduate chemistry laboratories. Some experiments are: (1) the determination of the density and degree of crystallinity of a polymer; and (2) the determination of the specific heat of a nonvolatile compound. (HM)
