Environmental education research often emphasizes the importance of community context, but conceptualization and measurement of environmental literacy has mostly occurred at the individual level, often focusing on individual behaviors. The environmental problems facing the world today require collective action--communities coming together to…

This panel's goal was to improve the validity and utility of measurement, design, and analysis in research on teaching through the stimulation of new methodological knowledge and through the identification and translation of useful existing knowledge from other descriptions. This panel tried to identify as many methodological problems as possible…

Two pathways in the development of a scientific concept can be differentiated: the limited-operationalization approach, which capitalizes upon the availability of an instrument; and the popular consensus approach, which comes from a sudden interest and popularity of the phenomenon in the real world. The phenomenon of mentoring is a contemporary…

This paper discusses problems encountered by researchers in applying the guidelines of Finkelhor (1986) for the selection of research instruments for gathering data on the effects of child sexual abuse. Discussion focuses on measures of effects of the abuse experience, measures of post-abuse experiences, and of mediating variables. The data…

Investigators interested in conducting school health research face many challenges. This article focuses on an analysis of research designs and measurement issues that most frequently confront school health researchers. (Author/DF)

The present paper reviews the techniques commonly used to correct an observed correlation coefficient for the simultaneous influence of attenuation and range restriction effects. It is noted that the procedure which is currently in use may be somewhat biased because it treats range restriction and attenuation as independent restrictive influences.…

A study was conducted to clarify some of the ambiguous findings reported in the media dependency literature. Specifically, it sought to establish whether relationships between use of the media and surveillance gratifications obtained from that use were affected by an individual's medium of primary reliance or whether these relationships might be…

It has been increasingly realized that (1) multivariate methods are essential in most quantitative studies (Fish, 1988; Thompson, 1992), and (2) all conventional parametric analytic methods are correlational and invoke least squares weights (e.g., the beta weights in regression) (Knapp, 1978; Thompson, 1991). The present paper reviews one very…

An introduction to profiles is presented with examples provided to permit an overall appraisal of the potential of profiles, of the principles upon which they might be based, and of the problems that will have to be overcome if their potential is to be realized in practice. The larger scale examples of profiles discussed are the Scottish Pupil…

Numerous forms and meanings of validity have been developed to provide researchers with the opportunity to assess the many potential sources of ambiguity that exist in any research finding. A Validity Network Schema (VNS) developed by Brinberg & McGrath (1982) is extended and elaborated in order to describe the components of the research…

Because health behavior is often concerned with dynamic constructs, a longitudinal approach to measurement is needed. The Longitudinal Guttman Simplex (LGS) is a measurement model developed especially for dynamic constructs exhibiting cumulative, unitary development measured longitudinally. Data from the Television Smoking Prevention Project, a…

By focusing on "appropriateness" and "adequacy" of inference and action, unified validity may be misused in rejecting valid test outcomes. The notion of levels of validity is challenged, the necessity of assumption is argued, and experience is proposed as the basis of validity. "Consequential validity" is interpreted as an optional predictive…

A study by Malcolm R. Parks reported in "Communication Monographs" called into question the cross-situational validity of the Personal Report of Communication Apprehension (PRCA). Park's study, however, is flawed in many ways. He does not provide an adequate definition of "situation." Both the type of factor analysis he chose…

This paper addresses neglected questions in item response theory (IRT): measurement of ability or trait parameters and item difficulty in the Rasch model; measurement of individual change based on a Rasch test; and the general framework for detection of differential item functioning under the Mantel-Haenszel procedure. (SLD)

Assessing results of grants programs is illustrated with evaluation activities of the National Science Foundation and other federal agencies. Methods considered are ex-ante peer review of proposed work, ex-post peer review of completed work, publications-based methods, and "look-back" methods tracing contributions of past work and…
