Reviews three software packages: 1) a package containing 68 programs covering general topics in chemistry; 2) a package dealing with acid-base titration curves and allows for variables to be changed; 3) a chemistry tutorial and drill package. (MVL)

Discusses a method for teaching time pulsed NMR principals that are as simple and pictorial as possible. Uses xyz coordinate figures and presents theoretical explanations using a Fourier transformation spectrum. Assumes no previous knowledge of quantum mechanics for students. Usable for undergraduates. (MVL)

Attempts to provide an intuitive understanding of steady state kinetics. Discusses the meaning of steady state and uses free energy profiles to illustrate and follow complex kinetic and thermodynamic relationships. Provides examples with explanations. (MVL)

Presents entropy analysis of four processes: a chemical reaction, a heat engine, the dissolution of a solid, and osmosis. Discusses entropy, the second law of thermodynamics, and the Gibbs free energy function. (MVL)

Discusses three areas of catalysis: homegeneous, heterogeneous, and enzymatic. Explains fundamentals and economic impact of catalysis. Lists and discusses common industrial catalysts. Provides a list of 107 references. (MVL)

Discusses the effects caused by small amounts of carbon dioxide usually present in water and acid-base equilibria of dilute solutions. Notes that dilute solutions of most weak acids and bases undergo significant dissociation or protonation. (MVL)

Proposes that higher education insist more on the education of its chemists and less on strictly instrument training. Lists several instances where education may have been more useful than the strict training military officers received. Discusses the role of chemists in society. (MVL)

Discusses a new Australian Academy of Science secondary chemistry textbook that provides a more interesting, enjoyable, and understandable base to a wider spread of students. Notes that rigor is maintained for use in college prep courses. Lists context for change, guiding philosophies, and the table of contents. (MVL)

Discusses the problems of grading an organic laboratory course. Proposes that the grade should be based as: products--30 percent of the grade; notebooks--30 percent of the grade; exams and final report--40 percent of the grade. Gives an exception policy for special considerations. (MVL)

Compares the abilities of pre-nursing and mainstream chemistry students in general chemistry courses. Finds no significant difference between the populations. Lists topics covered, representative test questions, and performance comparisons. (MVL)

Describes a new BS degree in secondary science/mathematics teaching being offered at Florida State University. Notes that the science concentration is either chemistry-physics or chemistry-biology. Indicates approximately 40 semester hours split between the science subjects are required. Notes that both a prospective and inservice track are…

Compares class size and faculty rating by students. Warns that certain instructors may not be effective with large class size (>100) but may be very effective with small class size. Infers that some poor large class instructors do not improve with time. (MVL)

Describes eight uses of the microcomputer in the chemistry classroom. Includes games, simulations, and graphics programs most of which are available from Project SERAPHIM. (MVL)

Describes a take-home exam story problem based on stoichiometry. Requires the student to determine the percentage of phosphoric acid in a large container of nitric acid if a man fell into it. Provides assumptions, clues, and an acceptable solution. (MVL)

Describes two demonstrations: 1) the effect of polarity on solubility using sodium dichromate, TTE, ligroin, and water to form nonpolar-polar-nonpolar layers with the polar layer being colored; 2) determination of egg whites to be yellow by determining the content of yellow colored riboflavin in the egg white.
