New ways of obtaining environmental data are being developed to meet the demand for comprehensive, accurate, and timely information on the environment. This article examines four developments that are transforming the entire field of environmental measurement: spectroscopy; satellite transmission of environmental data; remote sensing; and…

A nasal separator was used to measure the oral and nasal components in the speech of a normal adult Australian population. Results indicated no difference in oral and nasal sound pressure levels for read versus spontaneous speech samples; however, females tended to have a higher nasal component than did males.

The conclusion of the two-part feature on the S1 metric (International System of Units) reviews the basics and some of the rules technical teachers need to know in order to prepare their students for the changing world. (Author)

The article considers: (1) three fundamental principles for measurement, (2) facts about typewriting and stenographic skills that bear on their measurement, (3) recommendations for testing in accord with those facts and with basic measurement principles, and (4) the establishment of standards and modes of scoring and grading.

The skills, understandings, and attitudes necessary for an effective instructional supervisor were identified in the literature (using, for the most part, those materials written since 1975). Twenty-six elements were identified and clustered into six areas for a self-evaluation instrument that can give supervisors a means to describe and analyze…

A questionnaire was mailed to 50 major chemistry departments, 112 smaller chemistry departments, and 25 chemical engineering (CE) departments. The survey (included in an appendix) consists of a series of questions on two broad subjects--the current inventory at the surveyed institutions and the needs for instrumentation. Responses were received…

Discusses advances made in chemical analysis instrumentation used in environmental monitoring. This first of two articles is concerned with analytical instrumentation in which detection and dispersion depend ultimately on the properties of gaseous molecules. (JR)

The Illinois Ratings of Teacher Effectiveness (IRTE) is an instrument for recording senior high school student perceptions of teacher performance in ten trait areas: teacher appearance, ability to explain, friendliness, grading fairness, discipline, outside classroom assignments, enjoyment of teaching, voice, mannerisms, and command of subject…

Includes a syllabus for lecture and laboratory in a course emphasizing principles of operation rather than trouble shooting. (GH)

This researcher investigated two problems: (1) the accuracy and validity of instruments which measure Piagetian levels of thought; and (2) the need for more detailed models of concrete and formal operational structures, both as they develop and consolidate, and in their most highly developed state. Several tasks such as the Piagetian correlations…

ELEMENTARY SCHOOL TEACHERS' RESPONSES TO THE EMOTIONAL AND DEVELOPMENTAL CHARACTERISTICS OF CHILDREN WERE USED TO DEVELOP A TEST INSTRUMENT WHICH WOULD BE OF VALUE TO TEACHERS, TEACHER-TRAINING PERSONNEL, AND SCHOOL ADMINISTRATORS FOR THE PLACEMENT OF TEACHERS AT THE MOST APPROPRIATE GRADE LEVEL. ELEMENTARY TEACHERS WERE DIVIDED INTO PRIMARY…

Included in these proceedings are 11 formal papers presented by leading researchers in the field of thermal comfort and heat stress at a symposium held for the purpose of exploring new aspects of indoor thermal environments, caused primarily by the impact of energy conservation in new and existing buildings. The contributed papers were from…
