The National Assessment of Educational Progress (NAEP) Validity Studies Panel undertook a systematic analysis to consider the domain of validity threats to NAEP and to identify the most urgent research priorities. A framework of six broad categories was developed: (1) the constructs measured within each of NAEP's subject domains; (2) the manner in…

Stepwise methods are frequently employed in educational and psychological research, both to select useful subsets of variables and to evaluate the order of importance of variables. Three problems with stepwise applications are explored in some detail. First, computer packages use incorrect degrees of freedom in their stepwise computations,…

This paper discusses the impact of sampling error on the construction of confidence intervals around effect sizes. Sampling error affects the location and precision of confidence intervals. Meta-analytic resampling demonstrates that confidence intervals can haphazardly bounce around the true population parameter. Special software with graphical…

This paper suggests that statistical significance testing and effect size are two sides of the same coin; they complement each other, but do not substitute for one another. Good research practice requires that both should be taken into consideration to make sound quantitative decisions. A Monte Carlo simulation experiment was conducted, and a…

Against an historical backdrop, this paper summarizes four uses of intraclass correlation of importance to contemporary researchers in the behavioral sciences. First, it shows how the intraclass correlation coefficient can be used to adjust confidence intervals for statistical significance testing when data are intracorrelated and the independence…

Certain noneconomic factors in collective bargaining are directly related to the negotiator's personal inclination to settle for the new contract. In this study, the pattern of relationships between the parties, the nature of the work itself, favorable recognition, team policy, and interpersonal relationships proved to be significantly related to…

This study attempts to assess the effects of ethnicity on educational achievement. (Author)

Suggestions for adapting NAEP procedures for local use are based on the assumptions that instructional decisions can be improved through systematic gathering of data and that every student is not tested. (Author/KM) Aspect of National Assessment (NAEP) dealt with in this document: Procedures (Utilization).

The present paper reported on a study designed to test two null hypothesis, first, the prediction that there was no difference in attitudes held by heterosexually and homosexually oriented males, second, there would be no difference in attitudes held by covert and overt male homosexuals.

The present study attempted to replicate the finding (Frase, 1973) that different organizations of a passage produce different levels of recall and also to determine if relevant learning might be less subject to these organizational effects than incidential learning. (Author)

This essay assesses the level of difficulty at which defined job tasks are performed by college or university presidents in light of certain variables. (Author)

The purposes of the present study were to compare the scores obtained by boys and girls on the McCarthy Scales of Children's Abilities (MSCA) and to assess differences in their abilities on the tests that constitute these Scales. (Author/RK)

Since an author's use of articles and (personal) pronouns is particularly sensitive to the variation in the degree of formality of his writing, it might seem that the terms of the opposition (romance, novel) might be quantitatively distinquished, using information about articles and pronouns. Author attempts such a project. (Author/RK)

Research tested the hypothesis that homogeneous subject groups would produce test responses with better homogeneity indices than those of the parent sample from which they were drawn. (Author)
