Describes the Center for Chemistry Education (CCE) model for teacher development. Provides three examples of professional development programs that were taken primarily from three CCE initiatives that include Teaching Science with Toys, Partners for Terrific Science, and Science Integration in Today's Elementary Schools. (Contains 12 references.)…

Presents a list of six concepts that form the basis of modern chemistry and that should be included in introductory chemistry courses. Discusses atoms, molecules, and ions; the chemical bond; molecular shape and geometry; kinetic theory; the chemical reaction; and energy and entropy. (JRH)

Describes a program designed to educate and train selected teachers to utilize hands-on activities, provide inservice workshops for their colleagues, and function as resource persons within their school districts. Discusses participant selection, workshops, and final project overview and evaluation. Concludes that the stated goals of the project…

Presented is an inspection form developed for use by college students to perform laboratory safety inspections. The form lists and classifies chemicals and is used to locate such physical facilities as: fume hoods, eye-wash fountains, deluge showers, and flammable storage cabinets. (BT)

Describes the use of cassette tape recordings in preparing freshman chemistry students for experiments in laboratories. The tapes are said to have decreased student anxiety in the laboratory and increased laboratory skills. (SA)

Discussed is the accuracy of three statements commonly used in chemistry books and in teaching chemistry. (HM)

Presented are three ways in which bioactivity of organic compounds has been introduced in organic chemistry courses. One is to point out a typical bioactivity of a given functional group. A second is to discuss biorganic mechanisms. A third is to draw structure-activity correlations (SAR). (Author/HM)

An analogy between electron transfer reactions of the elements and those of organic molecules is offered. Examples of organic electron transfer reactions are presented. The rationale of constructing an organic chemists' periodic table is also discussed. (HM)

Describes how Gibbs valley graphs can clarify the relation between the Gibbs function and chemical equilibrium. Gives examples from gas phase equilibria. (CS)

Presents information concerning a fundamental concept for understanding reaction rate, the idea of a rate-limiting step for a chemical reaction. Discusses problems in using flow analogies and introduces an alternative approach to finding the rate-limiting step based on locating the transition state of highest energy. (CS)

Presents a procedure for evaluating the required integrals for undergraduate students attempting to understand the consequences of perturbation theory. (CS)

Describes various uses for balloons in chemistry instruction, such as their use as stirring devices, gas reservoirs, sources of carbon dioxide, and as atomic models. (CS)

Provides short descriptions of chemists' applications of computers in instruction: an interactive instructional program for Instrumental-Qualitative Organic Analysis; question-and-answer exercises in organic chemistry; computerized organic nomenclature drills; integration of theoretical and descriptive materials; acid-base titration simulation;…

Describes the specifics of instruction in thermodynamics using a problem-solving technique introduced in a previous issue of this journal. (CS)

Discusses the concept of equilibrium in chemical systems, particularly in relation to predicting the position of equilibrium, predicting spontaneity of a reaction, quantitative applications of the equilibrium constant, heterogeneous equilibrium, determination of the solubility product constant, common-ion effect, and dissolution of precipitates.…
