Reliability generalization studies have provided estimates of the mean reliability coefficients and examined factors that explain the variability in the reliability estimates across studies for many different tests and measures. Different authors have used different data analyses to do such meta-analyses, and little research has addressed whether…

Using multivariate profile analytic techniques and sampling from both brain-injured and psychiatric populations, results of this study provide strong evidence that the Satz-Mogel abbreviated Wechsler Adult Intelligence Scale (WAIS) may be substituted for the standard WAIS for both general IQ assessment (in agreement with previous research) and…

This study was designed as a reconsideration of the weights used in evaluative decisions made with regard to research proposals submitted for funding at a major state university. The specific objective of the study was to determine whether the actual weights for components used in the evaluation of the proposals differed from a priori weights…

Given the concern for reliability in essay evaluation and the prospect of "error" variance in its absence, methods to promote interrater reliability in the evaluation of written compositions have been developed. These methods reduce variation in the value systems being applied by readers to texts, either by limiting the group of readers…

The Appalachia Educational Laboratory (AEL) developed an instrument for rating the technical quality of television programs. The project was undertaken in conjunction with AEL's Home Oriented Preschool Education (HOPE) program, but sought to produce a generalizable instrument. The final instrument contained a category for judging overall program…

The reliabilities of various observational measures were determined, and the influence of both the number and the length of the observation periods on reliability was examined, both separately and jointly. A single simplifying assumption leads to a variant of the Spearman-Brown formula, which may have wider application. (Author/CTM)

In order for individualized review in college admissions to be fair, issues of consistency and reliability must be considered. There are a number of ways to assess interrater reliability, including calculating the composite reliability of readers, computing the proportion of times that readers make consistent ratings, and evaluating reader…

This is an examination of the structural stability of affective characteristics relevant to education over a period of approximately seven months. Results indicated that the six interpretable factors were differentially stable over the time intervals. (Author)

A study examined the responses of 89 physical child abusers and 108 comparison subjects to the Child Abuse Potential Inventory to determine whether the inventory's response inconsistency scale could be used for screening for physical child abuse. The scale was rejected as a reliable or valid measure. (Author/MSE)

The reliability of visual inspection in single-case research was investigated by determining agreement among 5 judges visually inspecting 44 graphs depicting behavior from baseline to intervention. Agreement between visual inspection and statistical procedures was determined. Implications for single-case research are discussed. (SLD)

"Six Pillars of Dynamic Schools" uncovers an often overlooked truth--effective change is the product of hard work and dedication. There is no silver bullet; no matter how many programs, software packages, or new initiatives a district uses, the magic won't just "happen." Dynamic schools result from consistent and redundant focus on the fundamental…

This study investigated the reliability and validity of the Attitudes Toward Sex Offenders Scale (ATS) measurement by assessing attitudes of counselors in training towards juvenile sex offenders. The specific aims of this study were to determine (a) internal consistency of the ATS, (b) construct validity of the ATS based on exploratory factor…

This study was conducted to examine the effectiveness of embedding character education into the daily functions of instrumental music ensembles at Franklin High School in Portland Oregon. The participants in the study were the students of the researcher which may have been a delimitation. Their ages were from 14 to 19 years. Students from…

In today's economy, employers increasingly demand that workers have a high school diploma, yet America's graduation rates are unacceptably low, particularly among poor and minority students. Nationally, only about 70 percent of students graduate from high school on time with a regular diploma; for African American and Hispanic students, this…
