A formative intervention was employed to expose children to a variety of words to increase the breadth, or size of their vocabularies, and to repeatedly and supportively expose children to words to increase the depth, or semantic understanding of vocabulary. Science content words were selected since they are less likely to be included in an…

This technical specialty course is one of thirty-five courses designed for use by two-year postsecondary institutions in five nuclear technician curriculum areas: (1) radiation protection technician, (2) nuclear instrumentation and control technician, (3) nuclear materials processing technician, (4) nuclear quality-assurance/quality-control…

A 2-YEAR POST-SECONDARY CURRICULUM FOR TECHNICIANS IS PRESENTED. IT IS DESIGNED TO AID SCHOOL ADMINISTRATORS, SUPERVISORS, AND TEACHERS TO PLAN AND DEVELOP NEW PROGRAMS OR EVALUATE EXISTING PROGRAMS. IT WAS PREPARED PURSUANT TO A U.S. OFFICE OF EDUCATION CONTRACT BY THE INSTRUMENT SOCIETY OF AMERICA AFTER A NATIONAL SURVEY OF INSTRUMENTATION…

The recent Mid-Ocean Dynamic Experiment demonstrated large, coordinated research programs could be conducted. It also demonstrated use of many new instruments that have been under development for the last decade. (RH)

Based on an unpublished doctoral dissertation submitted to the University of Iowa, 1965.

Oivind Varkoy challenges music educators who start their educational work from well-defined learning outcomes and who then test and assess whether students have achieved these predefined ends. He argues that "ends-means-thinking," "assessment-thinking," and "some sort of market-philosophy" all relate to "instrumentalism" in which learners are…

The fundamentals, as well as the instrumentation of the quartz-crystal microbalance (QCM) technique that is used in an undergraduate laboratory experiment are being described. The QCM response can be easily used to change the properties of any system.

This is the second of two reviews dealing with analytical methods applicable to environmental chemistry. Methods are discussed under gas, liquid, or solid depending upon the state of the analyte during detection. (RH)

A personal colorimetric dosimeter for nitrogen dioxide was developed. Tests were performed to determine the response of these strips to various concentrations of NO2. The dosimeter strips were satisfactory for approximate determinations of total exposure (concentration + time) of nitrogen dioxide. The total exposure was calculated in terms of time…

A unifying modular approach to the description of modern instrumentation used in analytical measurements is described. Through the identification of five modules for analytical instrument, discussions pertaining to the different physical and chemical interactions can be better directed towards the similarities and differences in the actual methods.

Recent disasters have been of such scale and complexity that both the common assumptions made about learning from them, and the traditional approaches distinguishing natural from technological disasters (and now terrorism) are thus challenged. Beck's risk thesis likewise signals the need for a paradigmatic change. Despite sociological inflections…
