Two studies were completed that focused on instrumentation and procedural issues associated with measurement of lingua-palatal contact pressure (LPCP) during speech. In the first experiment, physical features and response characteristics of 2 miniature pressure transducers (Entran EPI-BO and Precision Measurement 60S) were evaluated to identify a…

The Avionics Instrument Systems career ladder (AFSC 325X1) provides flight line and shop maintenance training on aircraft instrument systems, electromechancial instruments, components, and test equipment. Duties involve inspecting, removing, installing, repairing, operating, troubleshooting, overhauling, and modifying systems such as flight and…

This memorandum reports on the preliminary research using a 24-item inventory designed to measure teacher's positions in relation to education issues and teaching decisions. The instrument, whose development is reported, is intended to identify representatives of two dichotomous styles of teaching: traditional, teacher-centered teaching and…

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…

This paper describes an attempt to facilitate students' learning of scientific concepts by using detectors that take as input physical information and output an instantiation of the concept. The principle hypothesis was that students would have a better understanding of the concept of image if they were taught to use a simplified, runnable model…

This report summarizes the findings of one of fourteen panels that studied progress in space science applications and defined user needs potentially capable of being met by space-system applications. The study was requested by the National Aeronautics and Space Administration (NASA) and was conducted by the Space Applications Board. The panels…

Students' attitudes toward and conceptual understanding of chemical instrumentation is surveyed. The study shows that, in general, the students' attitudes toward using instrumentation in the lab is quite positive and they felt that using instrumentation in the lab allowed them not only to connect "chemistry" and the "real world", but also to…

This study attempted to increase the size of the correlation between person-environment (P-E) fit and job satisfaction by rescaling the instrumentation of the Theory of Work Adjustment using the Bradley-Terry-Luce method and a probability-based fit index. This approach worked as well as, but failed to outperform, the currently used…

A three-week laboratory project involving synthesis and characterization of a layered manganese oxide provides an excellent vehicle for teaching important concepts of inorganic chemistry and instrumental methods related to non-molecular systems. Na-birnessite is an easily prepared manganese oxide with a 7 A interlayer spacing and Na[superscript +]…

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)

The assistive technology (AT) field acknowledges that different stakeholders vary in their perspectives of service delivery outcomes. While the literature delineates consumers, caregivers and providers as stakeholders with distinct views, very little research documents these unique perspectives. This study reports on the perspectives of (a)…

The purpose of this study was to develop an instrument, the "Job Seeking Self-Efficacy Scale," to measure perceived self-efficacy in job-seeking activities. The construction of the instrument, which incorporated tasks that have been determined to be important in job seeking for individuals with disabilities, was based on Bandura's theory of…

A description is given of work undertaken to develop a simple, specific, and reliable method for ozone. Reactions of ozone with several 1-alkenes were studied at room temperature (25C). Eugenol (4-allyl-2-methoxy phenol), when reacted with ozone, was found to produce relatively large amounts of formaldehyde as compared to other 1-alkenes tested.…

This study determines the effect of the Instructional Development Institute (IDI) on the skills of a group of District of Columbia public school instruction personnel in the use of the systems approach to instructional development. The following null hypotheses were tested: (a) IDI participants will not show significant gains in developing initial…

This instrument for describing writing is designed for use by teachers and researchers at the secondary and college levels. The two main sections are an outline of the complete instrument and the instrument itself. Various categories of the instrument can be used to describe general, descriptive, and explanatory prose; other categories are related…
