Several teaching aids including a microcomputer system, a process control laboratory, a mechanics laboratory, and a teaching polariscope are described. (RH)

An instrument to assess specific attitudes toward humanistic teaching strategies as well as toward science teaching was designed. (Author/GA)

Discussion is focused on one phase of the assessment problem--the development and improvement of instruments that can be used to measure the observable performance of competence of preservice teacher education students. (Author)

The Student Behavior Analysis System is a simple, reliable instrument for evaluating student behaviors and providing feedback to teachers on the efficiency and quality of their instructional strategies. (MB)

Explores questions, dilemmas, and issues facing individuals who teach and/or development undergraduate curricula in chemical instrumentation. Areas addressed include the instrumental analysis course, the laboratory, the role of electronics, and computer use. (JN)

Describes an experiment for recording two individual spectrophotometer response curves. The two curves are directly related to the power of transmitted beams that pass through a solvent and solution. An absorption spectrum of the solution can be constructed from the calculated rations of the curves as a function of wavelength. (JN)

Highlights an American Chemical Society (ACS) survey of 103 chemistry departments on their instrumentation needs. The 2-year study affirms that instruments used for chemical research and education are becoming outdated because of their age and changes in technology. The survey also reveals how departments plan to use newly acquired instruments.…

Discusses recent developments in the instrumentation and practice of analytical scale operations. Emphasizes detection devices and procedures in gas chromatography, liquid chromatography, electrophoresis, supercritical fluid chromatography, and field-flow fractionation. (JN)

Discusses: (1) rationale for chemical sensors in process analysis; (2) existing types of process chemical sensors; (3) sensor limitations, considering lessons of chemometrics; (4) trends in process control sensors; and (5) future prospects. (JN)

Reviews literature dealing with novel developments or important trends in electrochemistry. Areas examined include mass transfer, electrode kinetics, surface effects, chemically modified electrodes, coulostatic/galvanostatic methods, bioelectrochemistry, spectroelectrochemistry, and electrode instrumentation. Books, textbooks, and literature…

Presented is a review of selected literature on emission spectrometry published during 1982 and 1983. The review is organized under these headings: books and reviews; spectral descriptions and classifications; instrumentation; standards, samples, nomenclature, calibration, calculations; excitation sources; selected applications; and meetings. (JN)

Reviews developments in ultraviolet and light absorption spectrometry from December 1981 through November 1983, focusing on the chemistry involved in developing suitable reagents, absorbing systems, and methods of determination, and on physical aspects of the procedures. Includes lists of spectrophotometric methods for metals, non-metals, and…

Discussed are various types of electronic laboratory balances. (RH)

Described are available electronic laboratory balances. Information was supplied by the manufacturers or importers. (RH)

A variety of materials are described including spectrophotometers, chromatographs, voltmeters, recorders, and simple laboratory equipment. (RH)
