Describes a learning project in analytical chemistry in which students are required to select instruments from the manufacturers' literature that would be suitable for a given analytical problem. Several examples are given. (SA)

Some of the important modern developments of thin-layer chromatography are introduced. Discussed are the theory and instrumentation of thin-layer chromatography including multidimensional and multimodal techniques. Lists 53 references. (CW)

A comparison of 22 students in a traditional curriculum and 70 in a curriculum using speech science instrumentation demonstrated that opportunities to experience research improved attitudes toward and comfort with the research process. Findings support early introduction of scientific method into the communication disorders curriculum. (SK)

This book was written to help introductory biology teachers gain a basic understanding of contemporary bioinstrumentation and the uses to which it is put in the laboratory. It includes topics that are most basic to understanding the nature of biology. The book is divided into five sections: (1) "Separation and Identification" that includes…

Describes a group of short courses, primarily for the high school science teacher, dealing with the chemistry of drugs, food, and water pollution; and a group of short courses, primarily for the full time college student, dealing with scientific instrumental methods. (MLH)

Describes modules designed to enable a student to learn a measurement technique and familiarize himself with measurement instrumentation independently of a laboratory course. Presents an example of a module involving the measurement of electrical resistance and lists other modules that have been developed. (GS)

Describes a combined demonstration and student experiment course to illustrate fundamental techniques, instrumentation, and concise report writing. Describes experiments including tensile tests, heat treatment, equilibrium diagram, microexamination, strain measurement, and recrystallization. (GH)

Describes some of the advantages of having the science teacher develop, use, maintain, and troubleshoot the new instructional materials. (GA)

Describes a device for maintaining the proper water level in knife boats during ultramicrotomy. Water levels in troughs are adjusted rapidly and precisely during the cutting process. Illustrations are included. (Author/MA)

The construction of an operational amplifier for use in a chemical instrumentation course is described. (CP)

Describes a two-term course in electronic instrumentation for chemistry and physics students. The first term focuses on analog circuits and the measurement of voltage, current, and impendance. The second-term course focuses on digital pulses/logic, microcomputer organization, and assembly language programing and interfacing to experiments. (JN)

Discusses various topics related to the interfacing of computers, focusing particularly on methods of data collection using instruments. Topics include serial digital connections (examining RS 232C and V.24, physical protocol, electrical protocol, and other areas) and parallel digital connections. (JN)

Presents three ideas to help hold costs down in purchasing and using science equipment. These include (1) use of pencils and other graphite rods as sensors in potentiometric titrations, (2) rubber bulb modification for pipetting, and (3) a heater for a glassware bath. (JM)

Describes a modular approach to help select the most effective instruments for particular applications. In the approach, an instrument is considered to be a system composed of modules, each module performing a particular function. General input/output functions of various modules, how they modify signals, and module sensitivity are discussed. (JM)

Discusses how computational errors arise in analysis of data and how they can be minimized. Shows that all computations are subject to roundoff/truncation errors and how such errors are propagated and influence the stability and condition of a reaction. Applications to procedures used in analytical chemistry are addressed. (JN)
