Questions the continued misuse of Markovnikov's Rule in organic chemistry texts. Claims that the results of several studies that show the reaction to be more complex than it appears at first. Criticizes authors of new texts who have perpetrated the rule based on reading older texts. (TW)

Describes a physical chemistry experiment that uses Fourier transform (FTIR) spectrometers and microcomputers as a way of introducing students to the spectral storage and manipulation techniques associated with digitized data. It can be used to illustrate FTIR spectroscopy, simple kinetics, inorganic mechanisms, and Beer's Law. (TW)

Presents the text of the Priestly Medal Address presented June 7, 1988 at the special chemical education awards symposium of the Third Chemical Congress of North America in Toronto. Addresses the vertical nature of learning in science, the core curriculum debate, and advances in science. (CW)

Describes a program offered by the U.S. Department of Energy for undergraduate science and engineering students aimed at providing research experience during the academic year at the six national laboratories. Reviews the potential interest and benefits to students. (CW)

Suggests that there is a close relationship between deformation in the western United States and the large-scale motions of tectonic plates. Introduces very-long-baseline interferometry (VLBI) as one of the space-geodetic techniques, vector addition of the VLBI data and geological data, and a new geodetic network. (YP)

Discusses the Pioneer satellites' explorations of Jupiter and Saturn. Includes discussions of engineering, the messenger program, and future projects. Provides pictures, diagrams, and a description of the Pioneer "message" plaques. (YP)

Describes an activity to simulate enzyme activity. Discusses the processes demonstrated and variations in the assembly line method. (CW)

Describes a process for producing terminal or internal alkynes from ketones. Recommends using the experiment to aid in understanding acid-base strength, enolate anion chemistry, reaction at carbon versus oxygen, use of polar aprotic solvents, and elimination and nucleophilic substitution reactions. (ML)

Describes the use of student journals in a liberal arts chemistry class taken as part of the general education requirements by nonscience majors. Discusses the structure, grading, process, and benefits of the journal and its use in the course. (CW)

Suggests an approach which treats the electric circuit as a channel through which energy flows and to which the application of energy conservation makes the distinction between electromotive force and potential difference unnecessary. Equations, examples, and visual representations are included. (RT)

Describes the use of assumptions, restrictions, and constraints in solving difficult analytical problems in engineering. Uses the Navier-Stokes equations as examples to demonstrate use, derivations, advantages, and disadvantages of the technique. (RT)

Points out that many of the demonstrations explained as examples of inertia are in reality more related to some other effect, and that mass plays a very small role in the result. Describes what really happens in the demonstration. (YP)

Describes a program option for undergraduate chemical engineering students interested in biotechnology. Discusses how this program is deployed at the University of Southern Florida. Lists courses which apply to this program. Discusses the goals of teaching applied microbiology to engineering majors. (CW)

Describes three activities, substrate inhibition, product inhibition by fructose and glucose, and gel immobilization of invertase for use with undergraduate biochemistry classes. Discusses materials, methods, and results. Stresses the advantages of practical exercises in undergraduate classes. (CW)

Reports on a study into the use of three classroom communication techniques in an upper-level crop physiology course. Results indicated that three-fourths of all previous students wished their college coursework had offered more opportunities for public speaking. (TW)
