Describes two variations of an air sampler and analyzer that are inexpensive to construct, easy to operate, and designed to be used in an educational program. Variations use vacuum cleaners and aquarium pumps, and white facial tissues serve as filters. Samples of air pollution obtained by this method may be used from early grade school to advanced…

Some of the important modern developments of thin-layer chromatography are introduced. Discussed are the theory and instrumentation of thin-layer chromatography including multidimensional and multimodal techniques. Lists 53 references. (CW)

Describes the function of the various parts of the microscope and their integration in the formation of an optical image. Presents a procedure for setting up a microscope to obtain maximum resolution and contrast for each objective lens at all magnifications. (JRH)

Investigates the effect of movement instruction on beginning instrumentalists' steady beat perception, synchronization, and performance. Finds that a group receiving movement instruction did not perform significantly better than a control group at perception but did perform significantly better at synchronization and performance. Notes low,…

A comparison of 22 students in a traditional curriculum and 70 in a curriculum using speech science instrumentation demonstrated that opportunities to experience research improved attitudes toward and comfort with the research process. Findings support early introduction of scientific method into the communication disorders curriculum. (SK)

This module provides instructional materials that are designed to help teachers train students in job skills for entry-level jobs as instrumentation technicians. This text addresses the basics of troubleshooting control loops, and the transducers, transmitters, signal conditioners, control valves, and controllers that enable process systems to…

The objectives of this study were to: (a) determine if very young children will wear an accelerometer for relatively long periods of time and comply with the protocol for its use; (b) evaluate how well a caregiver can estimate the activity level of his/her infant or toddler when completing an exposure-oriented time activity diary; and (c) compare…

Recent progress in wireless and sensor technologies has lead to a new development of learning environments, called context-aware ubiquitous learning environment, which is able to sense the situation of learners and provide adaptive supports. Many researchers have been investigating the development of such new learning environments; nevertheless,…

This document contains a project report and procedures manual from a project in which a group of junior colleges and postsecondary technical schools in Texas developed, pilot tested, and disseminated performance criterion-referenced occupational examinations for technical occupations. The report describes how teachers and industry personnel…

This analysis covers tasks performed by an industrial instrument mechanic, an occupational title some provinces and territories of Canada have also identified as industrial instrumentation and instrument mechanic. A guide to analysis discusses development, structure, and validation method; scope of the occupation; trends; and safety. To facilitate…

This book was written to help introductory biology teachers gain a basic understanding of contemporary bioinstrumentation and the uses to which it is put in the laboratory. It includes topics that are most basic to understanding the nature of biology. The book is divided into five sections: (1) "Separation and Identification" that includes…

The authors describe a leisure counseling model. Key components of the model are skill, expertise, and warmth of the counselor. Three instruments for assessing interests and finding appropriate leisure activities have been developed and are used as part of the model. (SE)

Describes a group of short courses, primarily for the high school science teacher, dealing with the chemistry of drugs, food, and water pollution; and a group of short courses, primarily for the full time college student, dealing with scientific instrumental methods. (MLH)
