This book provides an overview and discussion of the evidence base of effective school inspections; reflecting on issues of validity and reliability of school inspections in relation to school effectiveness research, unintended consequences and emergent roles and responsibilities of Inspectorates of Education. Chapters include findings from…

Meta-analytic reliability generalizations (RGs) are limited by the scarcity of reliability reporting in primary articles, and currently, RG investigators lack a method to quantify the impact of such nonreporting. This article introduces a stepwise procedure to address this challenge. First, the authors introduce a formula that allows researchers…

In educational research, characteristics of the learning environment (e.g., social climate, instructional quality, goal orientation) are often assessed via student reports, and their associations with outcome variables such as school achievement or student motivation then tested. However, studying the effects of the learning environment presents a…

Numerous studies have shown increasing item reliabilities as an effect of the item position in personality scales. Traditionally, these context effects are analyzed based on item-total correlations. This approach neglects that trends in item reliabilities can be caused either by an increase in true score variance or by a decrease in error…

Discusses the definition of creativity and the broad methodological issues associated with organizational creativity. Reviews the most relevant theoretical models for studying creativity in organizations. Specific methodological requirements for studying creativity in organizations are then discussed, with emphasis on issues of validity and…

This paper describes how a naturalistic inquirer can demonstrate rigor, or trustworthiness, and how an auditor might assess it. Looking at both inquiry products and processes, Part 1 of this paper describes how an audit may assess whether an inquiry's findings and conclusions are grounded in the raw data, and whether appropriate conventions were…

The study, with 79 rehabilitation therapists evaluating 21 single-subject graphs, found that the low interrater agreement often associated with visual analysis of single-subject data may be improved by simple supplements (such as trend lines) to visually inspected charts. (Author/DB)

A conceptual model of quality of life, developed at the Centre for Health Promotion at the University of Toronto (Canada), and associated instrumentation for collecting data from persons with developmental disabilities are presented. Results from a preliminary study with 41 participants support the reliability and validity of the model's…

In recent years educators have been utilizing judgmental methods, such as the ones advocated by Ebel and Angoff, to set minimum competency standards on test items. This study was designed to investigate the reliability and validity of these two procedures in setting minimum levels of performance on 175 vocational evaluator competency statements.…

This research report describes the reliability and validity of hand-held dynamometer measurements of knee extension force obtained from 13 patients referred for physical therapy. Results found that hand-held dynamometry can be used to obtain reliable measures of muscle strength; however, correlation between strength measures and function was not…

The Correct Information Unity analysis for measuring the communicative information and efficiency of connected speech was applied to the naturally occurring conversation of a person with moderate aphasia. Results indicated low intrarater and interrater reliability although reliability of word counts was good. Most rater disagreements resulted from…

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…

The overall poor quality of educational software on the market suggests that educators must continue efforts to evaluate available packages and to disseminate their findings. In this paper, weaknesses in published evaluation procedures are identified, and an alternative model, the York Educational Software Evaluation Scale (YESES), is described.…

A step-by-step outline is presented for testing the applicability of Lotka's law of scientific productivity. Steps include the computation of the values of the exponent and constant based on Lotka's method and the test for significance of observed frequency distribution against the estimated theoretical distribution derived from Lotka's formula.…

The focus of this study was on the visual analysis of time series data for evaluating educational programs. Two characteristics of the data--changes in slope and variability--and two characteristics of evaluation--training in data utilization and the use of aimlines/decision rules--were manipulated. A total of 51 students and/or teachers in…
