Describes an experimental method of measuring the molecular weight and subunit corporation of an oligomeric protein. (SL)

Describes a recording gas microvolumeter constructed to carry out sensitive studies of the kinetics of photodecomposition of water. (SL)

Summarizes the National Assessment of Educational Progress (NAEP) study that, among other things, profiles the cognitive abilities of 17-year-olds. The editorial ends by asking how chemistry teachers can make use of this information to improve their effectiveness in teaching to the present type of student. (MR) Aspect of National Assessment (NAEP)…

Proposes a program for chemistry teacher education to provide students with the broad outlook considered necessary for interdisciplinary treatment of environmental issues. A course of study syllabus is included along with a comparison of undergraduate chemistry programs. (MR)

Discusses how electrostatic interactions can be taught quantitatively through Coulomb's Law at a variety of points in a chemistry curriculum. Each type of interaction is shown at both the intramolecular and the inter-"molecular" levels. (MR)

Presents a detailed analysis of the thermodynamic equation dE = TdS - PdV to illustrate how chemistry teachers may present chemical potential by a route free from the terrors of partial derivatives. (MR)

Provides the summary report of a symposium. The major topics summarized are, how many foreign chemistry students are in American universities, the quality of their academic preparation, language problems, what kind of education is best for them, and reverse brain-drain. (MR)

Summarizes the Ising model of ligand binding as it applies to cooperative binding to long chain molecules. Also presents some illustrations which help to visualize the connection between the interaction parameters and the shape of the binding isotherm. (Author/MR)

Provides an application of a direct group theory method to the determination of the number and symmetry of M-C-O groups. The method is explained and three illustrative examples are given. (MR)

The use of Dischler equations in conformational analysis is described relative to the "nmr" spectrum analysis of bismethylene fragments of both acylic and cylic systems. Also, an approach to analyze the AA'BB' spectrum of these bismethylene fragments is described. (MR)

A computational method is described for analyzing first-order kinetic data obtained at arbitrary time intervals. The method has uses in research and undergraduate instruction as well. (MR)

Three demonstrations are described: paramagnetic properties of Fe(11) and Fe(111), the preparation of polyurethane foam: a lecture demonstration and the electrolysis of water-fuel cell reactions. A small discussion of the concepts demonstrated is included in each demonstration's description. (MR)

Reports on the long term comparison between a group of "high risk" college freshmen who were given a supplemental chemistry course and another group who did not have the course. The supplemental course was found to produce only a short term rise in students' grades. (MR)

A description is given of a three credit-hour course entitled Radiation and the Environment. The course syllabus along with descriptions and criticisms of the course texts, are included. Also, some quotes from student's papers are presented indicating attitudes toward nuclear energy at the end of the course. (MR)

An experiment is described which uses lead sulfide to illustrate the concept of definite proportions as well as the union of atoms to form compounds. This experiment has been successfully used with ninth graders. The advantages of this experimental procedure over available alternatives are listed. (MR)
