Summarizes the recommendations of a Conference centered on new approaches in the professional training of chemists. Recommendations are for three areas of higher and inservice education: curriculum, industry-academe interaction, and career programs. (MLH)

Describes an instructional approach for teaching the cause-and-effect relationship between the qualities of atoms and the properties of their chemical compositions. Discusses atomic structure, ionization energies, homonuclear and heteronuclear bonding, and bond dissociation. (MLH)

Describes the basics of the International System of Units (SI Units) and specific application of these units in the teaching of chemistry. (MLH)

A retired judge for chemistry teacher awards discusses some aspects of current chemical education. (MLH)

Discusses the copper-containing molecule that carries oxygen to the tissues of animals in the phyla mollusks and arthropods. (MLH)

Discusses three methods of correlating bond orders and bond lengths in unsaturated hydrocarbons: the Pauling theory, the Huckel molecular orbital technique, and self-consistent-field techniques. (MLH)

Discusses a way to use the free energies for reactions of solvated electrons as a way of establishing an absolute rather than arbitrary zero for electrode potentials. (MLH)

Discusses popular erroneous concepts about the thermodynamic standard state of substances, including the fact that standard state is often confused with the concepts of standard temperature and pressure. (MLH)

Discusses the dipositive oxidation state of silicon and describes laboratory experiments concerning the synthesis and reactions of silicon difluoride. (MLH)

Presents a set of rules for determining reaction orders of reacting species from the shape of a plot of the log of the pseudo-xth-order rate constants versus the log of the concentration being varied. (MLH)

Discusses the relationship between adsorption isotherms and elution peak shapes in gas chromatography, and describes a laboratory experiment which involves the adsorption of hexane, cyclohexane, and benzene on alumina at different temperatures. (MLH)

Presents examples of compounds in which delocalization effects are sustained in the presence of potentially interfering, saturated carbon atoms. (MLH)

Discusses an undergraduate course which includes lectures, laboratory, and field trips and is designed for the interim winter semester. The course is interdisciplinary, involving a study of the biochemistry, pharmacology, and physiological significance of compounds from marine flora and fauna. (MLH)

Describes an experiment in which the student is presented with the problem of selecting a suitable indicator for the determination of the hydroxide in basic copper chromate. (MLH)

Describes an interview-type study of 15-year-old chemistry students that revealed a poor understanding of the mole concept, and discusses the major features of their misunderstandings. (MLH)
