New technologies have been developed to diagnose such disorders as cancer, heart disease, and defects of the newborn in presymptomatic stages. Several technologies, including amniocentesis, radioimmunoassay, enzyme immunoassay, multichannel analysis and others are discussed. Development of these technologies and issues related to their use are…

Describes a lesson in a research methods class teaching undergraduate students instrument construction and interviewing techniques, using film viewing, discussion, and interviewing exercises. Student reactions were positive. (CK)

Listed are available control parameters including basic definitions and concepts and methods of measurement. The application of these parameters to the control of water and wastewater treatment plants is also outlined. (CS)

Presents a laboratory demonstration that helps students understand the concept of microscope calibration. (JRH)

A visual tool used to evaluate instructional program performance has been designed by the University of Hawaii Community College system. The tool combines features from traffic lights, blood-chemistry test reports, and industry production control charts, and is labeled the Program Health-Indicator Chart. The tool was designed to minimize the labor…

An electronic laboratory station was designed for student use in learning electronic instrumentation and measurement by means of the computer-guided experimentation (CGE) system. The station features rack-mounted electronic laboratory equipment on a laboratory table adjacent to a PLATO IV terminal. An integrated logic system behind the laboratory…

New apparatus and equipment are briefly described. Sources of materials are given. (MLH)

The purpose of this study was to examine the relationship among several instruments that purport to measure empathy in the counseling process. The results from a correlational and factor analysis indicated a positive and significant relationship between certain measures used in this study. (Author)

Infrared remote sensors, plus photometric interpretation and digital data analysis are being used to record the stresses on air, water, vegetation and soil. Directly recorded photographic information has been the most effective recording media for remote sensing. (BT)

A pneumotachographic investigation of intervocalic /p/, /t/ and /k/ was undertaken to isolate physiological parameters responsible for coarticulatory air-flow phenomena. Airflow was most sensitive during the /k/ closure phase. The dynamics of the closure phase for each place of articulation and their implications for pneumotachography are…

Discusses instrumentation and describes such research areas as the albedos of the brighter planets, rotation rates and atmospheres of the larger and brighter satellites, brightness changes of outer planets, asteroid rotation rates, and variable stars. (GS)

This document presents twenty-two instruments for the examination of practices in school management by principals. They are an outcome of the Principals 505 Project, which was intended to develop competency standards for the certification of principals based on observed classroom practice. The instruments organize descriptors, which identify…
