The representation of women among recipients of chemistry Ph.D. degrees has increased in recent years, but their representation among the faculty in academic departments is still below what would be expected given the proportion of degrees received. Articles published in the "Journal of Chemical Education" in 2010 documented a hostile…

Despite the demonstrated learning benefits of peer evaluation, fears of teachers about its low reliability may restrict its use. In this study, the validity of peer assessment, in terms of agreement with the ratings of the teacher, has been tested in an organic chemistry course. The students were organized into small groups and commissioned to…

Synthesis of pure enantiomers is a key issue in industry, especially in areas connected to life sciences. Catalytic asymmetric synthesis has emerged as a powerful and practical tool. Here we describe an experiment on racemic reduction and asymmetric reduction via a catalytic hydrogen transfer process. Acetophenone and substituted acetophenones are…

Nuclear magnetic resonance (NMR) spectroscopy is widely used by chemists. Furthermore, the use of NMR spectroscopy to solve structures of macromolecules or to examine protein-ligand interactions is popular. Yet, few students entering graduate education in biological sciences have been introduced to this method or its utility. Over the last six…

An historical investigation into the theory of valency as developed in the course of the second half of the 19th Century. Opposing views on one aspect of valency are examined and contrasted. (DF)

Presents a programed method that inventories and classifies hazards. 8iscusses the following topics: (1) student and hazard source, (2) elimination of the source, (3) adaptation of the source, (4) isolation of the source, (5) adjustment of the surroundings, (6) isolation of man, and (7) personal protective equipment. (MVL)

Presents a table of events that lists chronologically, in parallel columns, major occurrences in the histories of both the United States and science, as well as the names of individuals normally associated with an event or period. (MLH)

Discusses the presentations of chemical demonstrations, hands-on experiments, and magic shows. Presents 12 guidelines to follow when presenting chemical demonstrations. Points out the obligations of the presenters for the safety concerns of the general public. Notes information available from the American Chemical Society. (MVL)

Describes topics in chemistry as related in the Classics Illustrated publications. Provides a list from "The Pioneers of Science" series with issue date, number, and biograhical topic. Lists references to topics in chemistry. Presents many pages from these comics. (MVL)

The standard introduction to stoichiometry and simple exemplars can motivate students to learn the stoichiometric studies and the condensation reaction that occurs between amino acids to form the peptide bond. This topic can be integrated into general chemistry courses as an alternative to inclusion of a separate biochemistry course that could be…

Discusses the results of the 1975 Examination for General Chemistry, and summarizes descriptive statistics as well as ten different subsets of instructional topics. The major results and conclusions are reported in three separate profiles. (HM)

The foundation of science, and of thermodynamics in particular, can be developed cogently and without arbitrariness. The goal of science, description of nature, is externally given; it requires a set of basic concepts as indispensable tools. Mathematics has no similar externally given goal. (Author/TS)
