A variety of methods for producing images and some of the tools available for image analysis are described. (BB)

A discussion of the basic design and characteristics of gas chromatography-mass spectrometry systems used in clinical chemistry. A comparison of three specific systems: the Vitek Olfax IIA, Hewlett-Packard HP5992, and Du Pont DP-102 are included. (BB)

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…

This curriculum guide was designed for use in postsecondary instrumentation technology education programs in Georgia. Its purpose is to provide for development of entry level skills in instrumentation technology in the areas of knowledge, theoretical structure, tool usage, diagnostic ability, related supportive skills, and occupational survival…

How to move science-based labs online has been one of the main obstacles associated with the development of online science programs. In the spring of 2006 and again in 2007, we organized online workshops broadly based around the central theme of Moving the Lab Online. The objective of these workshops was to provide a forum for the exchange of…

Discusses reasons for questioning the underlying assumptions of instruments designed to measure knowledge of the nature of science. Recommends that researchers recognize that conflicting models of science exist, and that each instrument related to these models must specify all philosophic assumptions. (MLH)
