The author describes a new student teaching evaluation instrument designed to (1) reinforce instructional and supervisory models learned during preservice education and (2) to provide a bridge between university methods instruction and student teaching. (MJB)

Describes an empirical method for tuning a piano by matching measured fundamental frequencies to values determined using a pocket calculator. (Author/GA)

The present form of the GTOI is presented. The authors believe it has considerable potential as a set of guidelines for investigation of group outcome, as a systematic framework for reviewing the adequacy of published research, and as a tool for training students in the intricacies of research methodology.

Evaluation of a model of the dynamics of cumulative achievement, used to develop an instrument for predicting scholastic achievement, suggests that, while the instrumentation needs to be improved, reliability of the model-based approach warrants further work. (MJB)

Discusses the relative operating characteristic analysis of signal detection theory as a measure of diagnostic accuracy. Reports representative values of this measure in several fields. Compares how problems in these fields are handled. (CW)

Described is an experiment to investigate the plasticizer content in polyvinyl chloride (PVC) products. The experiment is designed for college students using an instrumental analysis laboratory. (RH)

Presents two lists: (1) important considerations for any total chemical analysis and (2) a condensed version that can be used by students to evaluate each analytical procedure. Benefits of using the condensed version (such as seeing that instrumentation is only one of several components of an analysis) are noted. (JN)

Software-driven instrumentation makes measurements that demand a computer as an integral part of either control, data acquisition, or data reduction. The structure of such instrumentation, hardware requirements, and software requirements are discussed. Examples of software-driven instrumentation (such as wavelength-modulated continuum source…

Describes a birefringence apparatus that can be assembled for less than $100 and can be used to measure both the dimensions and dipole moments of many macromolecules. Details are given of the construction and manipulation of the apparatus. (JN)

A microcomputer-controlled system for instrument processing and billing for complex analytical instruments funded by multiple sources in the University of California at Berkeley's College of Chemistry is described and its potential applications in other administrative situations are outlined. (MSE)

Examines trends in methods for deriving chemical information from a variety of systems and environments, focusing on improvements in sensitivity, specificity, speed and simplicity, and in sampling. Indicates that the increasing importance of analytical instrumentation requires reexamination of its coverage in educational curricula. (JN)
