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…

Simple slopes, regions of significance, and confidence bands are commonly used to evaluate interactions in multiple linear regression (MLR) models, and the use of these techniques has recently been extended to multilevel or hierarchical linear modeling (HLM) and latent curve analysis (LCA). However, conducting these tests and plotting the…

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)…

In this paper, our focus is on "young" mathematics teachers during their pre-service training because of the conditions that might enable them to develop professional uses of technology more easily than "older" teachers. By describing some aspects of teacher training in France, especially the distinction between level 1…

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…
