Discusses the use of lap-dissolve projection to give students pre-laboratory instruction on an upcoming experiment. In this technique, two slide projectors are operated alternately so that one visual image fades away while the next appears on the same screen area. (MLH)

Discusses the spectra of the tetrahedral permanganate ion to illustrate the interrelationships among the crystal field, ligand field, and molecular orbital theories. (MLH)

Discusses five goals for teaching courses concerned with science and human values. Also discusses advantages and disadvantages for the teacher. (MLH)

Discusses the discovery, background, and application of the trans effect and briefly outlines the life and work of its discoverer. (MLH)

Presents results of a survey of randomly selected U.S. colleges and universities concerning chemistry courses for nonscience students. Reports that 63 percent of the responding schools offer such courses and that 91 percent of the courses present topics that differ from those in traditional courses. (MLH)

Quantitatively investigates the applicability of using the steady state approximation in the kinetics of complex reactions with reversible reactions. (MLH)

Presents in table form information from numerous articles so that a particular reaction can be quickly located. (MLH)

Describes a rapid computer technique for plotting Eh-pH diagrams using a line printer. (MLH)

Discusses the activities and role of this committee, and reports on a recent conference. (MLH)

Describes an undergraduate experiment in which Gantrez AN polymer chains are crosslinked at the anhydride groups by the addition of the hydroxyl groups of triethanolamine, which also acts as a basic catalyst. (MLH)

Describes an experiment in which metal compounds, such as anhydrous oxides, are placed into a glass tube which is heated until the metal colors the glass. (MLH)

Describes seven computer simulations of laboratory experiments that allow students to direct experiments, make observations, and record data. (MLH)

Discusses a teaching program for introductory chemistry laboratories that allows for differences in student background and ability. The flexible program involves self-pacing and a classification of experiments; this permits slower students to proceed through remedial loops while advanced students proceed to more difficult experiments. (MLH)

Describes an interpretative experiment involving the application of symmetry and temperature-dependent proton and fluorine nmr spectroscopy to the solution of structural and kinetic problems in coordination chemistry. (MLH)

Describes an experiment that utilizes polarimetry to measure mutarotation of glucose and nmr spectroscopy to identify the structures of reactants and products of biochemical reactions. (MLH)
