Voltammetry is used as a model for teaching chemical instrumentation to chemistry undergraduates at the National University of Singapore. Lists six criteria used to select a successful teaching model and shows how voltammetry satisfies each criterion. (JN)

This module contains instructional materials on instrumentation to help teachers train students in the job skills they will need as beginning instrumentation technicians. The module addresses the nature of accessing, measuring, and controlling phenomena such as level, flow, pressure, and temperature. Students are introduced to the devices and…

This module provides instructional materials that are designed to help teachers train students in job skills for entry-level jobs as instrumentation technicians. This text addresses the basics of troubleshooting control loops, and the transducers, transmitters, signal conditioners, control valves, and controllers that enable process systems to…

This package consists of course syllabi, an instructor's handbook, and a student laboratory manual for a 2-year vocational training program to prepare students for entry-level employment as instrumentation and control technicians. The program was developed through a modification of the DACUM (Developing a Curriculum) technique. The course syllabi…

Discussed are two techniques that can be used to directly test the theory that the plates which make up the crust of the earth are still moving. Described are the use of satellite laser ranging and very long baseline interferometry. Samples of data and their analysis are provided. (CW)

Discussed is some of the confusion encountered in electrochemistry due to misunderstandings of sign conventions and simple mathematical errors. Clarified are issues involving emf series, IUPAC sign conventions, calculation of cell potentials, reference electrodes, the polarity of electrodes in electrochemical devices, and overpotential. (CW)

Describes a way to use computers in teaching chemistry, in this case in a demonstration lesson on supercooling using a thermister in a game port to interface the computer with cooling phenyl salicylate. Discusses the advantages over the traditional method of instruction. (CW)

Discussed are selected application and future trends in supercritical fluid chromatography (SFC). The greatest application for SFC involves those analytes that are difficult to separate using GC or LC methods. Optimum conditions for SFC are examined. Provided are several example chromatograms. (MVL)

Presented is a simple laboratory set-up for teaching microprocessor-controlled data acquisition as a part of an instrumental analysis course. Discussed are the experimental set-up, experimental procedures, and technical considerations for this technique. (CW)

Presents a low cost system with easily replaced electrodes for use in general chemistry. Notes the accuracy and wide applicability permit easy use in physical or quantitative chemistry experiments. Provides schematic, theory, and helpful suggestions. (MVL)

Analytical methods…

Maintains that the ability and experience of improvisation is an essential component in young musicians' education. Discusses one teacher's trial-and-error efforts in introducing improvisational exercises into her students classical training. Includes a list of resources and representative musical examples. (MJP)

Provides some tips on jazz instruction for the beginning music educator who may not have had much experience in that field. Specifically recommends teaching guide tones, the root, third, and seventh chords, as an invaluable aid to jazz improvisation. Includes musical notation showing guide tones for two jazz standards. (MJP)

Discussed is the integration of microcomputers into the science laboratory curriculum. The approach provides an exposure to important aspects of computer technology while preserving concrete experiences provided by hands-on laboratories. (CW)

Discussed are four major advantages to the use of microscale laboratories for teaching chemistry. Included are effects on waste generation, laboratory safety, reagent variety, and laboratory efficiency. (CW)
