Presents a chemical instrumentation laboratory experiment that introduces the methodology of the fabrication and evaluation of an ion-selective electrode. (CS)

Explains two approaches to the automatic arrest of a potentiometric titration. (SA)

Presents part two on the use of the detection of thermoluminescence as an analytical tool for the chemistry laboratory and allied science. This part discusses instrumentation used and investigates recent developments in instrumentation for thermoluminescence. (HM)

Three learning concepts important for adult learners are that learning is accelerated by making connections to prior information, people learn best when actively constructing knowledge, and instruments are important in supporting knowledge retrieval and construction. The paper explains how index cards can be useful instruments in learning. (SM)

A laboratory experiment designed as a model for studying enzyme activity with a basic spectrometer is presented. Included are background information, experimental procedures, and a discussion of probable results. Stressed is the value of the use of Nuclear Magnetic Resonance in biochemistry. (CW)

Described are six multipulse experiments with an emphasis on their application to common problems in chemistry. Exercises in relaxation time measurement, spin echoes, and polarization transfer are proposed. (CW)

Described are efforts to organize the research efforts concerning global change. Objectives include the development of long-term monitoring programs, global process research campaigns, and predictive computer models. (CW)

Studies the polarization effect on water by cations and anions. Describes an experiment to illustrate the polarization effect of sodium, lithium, calcium, and strontium ions on the water molecule in the hydration spheres of the ions. Analysis is performed by proton NMR. (MVL)

Describes a laboratory experiment designed to encourage laboratory cooperation among individual undergraduate students or groups. Notes each student contributes results individually and the exchange of data is essential to obtain final results. Uses the polarographic method for determining complex metal ions. (MVL)

Provides the electronic circuit schematic for the construction of a green vegetation sensor, the directions for its use, and suggestions for student projects. (JJK)

Describes the development of a research instrument that monitors student views on a broad range of Science, Technology, and Society (STS) topics. Qualitative data were used to produce the multiple-choice responses of this instrument which focuses on cognition rather than affect. Uses of the instrument include making cross-cultural comparisons,…

Some commercially available software tools that have potential applications in the analytical chemistry curriculum are surveyed and evaluated. Tools for instruction, analysis and research, and courseware development are described. A list of the software packages, the compatible hardware, and the vendor's address is included. (KR)

Argues for the use of instruments in introductory level chemistry and presents multiple perspectives on the issue. Reasons for employing instrumentation include the ability of introductory classes to reach a large number of students, the need to model situations in which scientists work, and student expectations regarding the use of technology.…

Students in the Electronics Engineering Technology program at Pennsylvania College of Technology designed and built a computerized dynamometer platform for testing dc brushless motors. As the capstone experience for EET-320, Measurement and Tests course, students were divided into teams of four and were given three weeks to complete the project.…

This report provides results of Phase I of a project that researched the occupational area of instrumentation technology, established appropriate committees, and conducted task verification. These results are intended to guide development of a program designed to train instrumentation technicians. Section 1 contains general information: purpose of…
