Describes an oscillating chemical reaction, and discusses numerous parallels to it in research, such as in fibrillation of the heart, body-clock rhythms of animals and plants, the self-assembly of multicellular organisms, and certain stripes in volcanic rock. (GA)

Describes the intuitive approach used in general chemistry and points out its pedagogical advantages. Explains how to extend it to acid-base equilibrium calculations without the need to introduce additional sophisticated concepts. (GA)

Presents two demonstrations; one on Boyle's Law, to illustrate the gas law and serve as a challenging problem for the students; the other is a modified Color Blind Traffic Light demonstration in which the oscillating reactions were speeded up. (GA)

Investigates the effects of high school chemistry experiences on the use of Piaget's operative structures. Reports that students who took chemistry scored higher than those who did not on a test of Piaget's operative comprehension. (GA)

Discusses two different uses of information theory in chemistry to present entropy and chemical structure analysis. (GA)

This course is based on the premise that a sound base in the mechanics and electrokinetics of the dispersed phase is essential for an understanding of the macroscopically apparent behavior of such disperse systems. (Author/BB)

The opinion is presented that chemical engineering education seems to emphasize the professor's research and/or professional interests with little regard for the real needs of the student who intends to become a practicing engineer. (BB)

This article looks at the problems of revision of laboratory courses. While revision of the syllabus of experiments is expensive, it is necessary to keep it up to date. The nature, causes, and rates of change in practical courses are discussed. (BB)

Describes the use of atomic spectra that are excited in inductively coupled plasmas for the simultaneous or sequential determination of the elements at all concentration levels. (HM)

This paper is a summary of remarks made at a recent symposium on new directions in the teaching of physical chemistry. The author takes exception to the claims made for the International System of Units (SI). (HM)

Presents some problems for quantum chemistry courses based upon model pseudopotentials. Also includes some useful formulas and tables of parameters associated with these problems. (HM)

Describes an interdisciplinary program in the areas of biochemistry, biology, and computer science offered at Chestnut Hill College, Philadelphia, Pennsylvania, to update 30 women in order to prepare them to return to the job market in chemistry. (HM)

Evaluates college students' understanding of chemistry as operationally defined by Bloom. The Test of Higher Cognitive Learning in Chemistry was administered to 488 students upon completion of a one-semester course in general chemistry. Significant differences were found among student mean scores at various cognitive levels. (HM)

Presents an explanation of the electron for secondary school chemistry teachers. Schrodinger's wave equation and Heisenberg's uncertainty principle are also discussed. (HM)

Presents a biochemistry experiment for college students that illustrates the purification of an enzyme. (HM)
