Prior research indicates that the overall reliability of performance ratings can be improved by using ordinary least squares (OLS) regression to adjust for rater effects. The present investigation extends previous work by evaluating the impact of OLS adjustment on standard errors of measurement ("SEM") at specific score levels. In…

A multilevel analysis approach was used to analyse students' evaluation of teaching (SET). The low value of inter-rater reliability stresses that any solid conclusions on teaching cannot be made on the basis of single feedbacks. To assess a teacher's general teaching effectiveness, one needs to evaluate four randomly chosen course implementations.…

A total of 4 raters, including 2 teachers and 2 research assistants, used Direct Behavior Rating Single Item Scales (DBR-SIS) to measure the academic engagement and disruptive behavior of 7 middle school students across multiple occasions. Generalizability study results for the full model revealed modest to large magnitudes of variance associated…

Direct behavior rating (DBR) has been described as a hybrid of systematic direct observation and behavior rating scales. Although single-item (DBR-SIS) and multi-item (DBR-MIS) methods have been advocated, the overwhelming majority of research attention has focused on DBR-SIS. This study employed generalizability theory to compare the…

In the lead article, Persson (2012a) focuses on salient issues that have not as yet been addressed by others, and which are relevant, and germane. With the advent of the Internet and web and e-mail, conversation and discussion among scholars have increased tremendously. At the current time, researchers are able to share their data, their thoughts…

In recent years, interest has grown in using classroom observation as a means to several ends, including teacher development, teacher evaluation, and impact evaluation of classroom-based interventions. Although education practitioners and researchers have developed numerous observational instruments for these purposes, many developers fail to…

Social scientists are frequently interested in assessing the qualities of social settings such as classrooms, schools, neighborhoods, or day care centers. The most common procedure requires observers to rate social interactions within these settings on multiple items and then to combine the item responses to obtain a summary measure of setting…

We examined how rater language background affects the scoring of short-answer, open-ended test items in the assessment of English language learners (ELLs). Four native English and four native Spanish-speaking certified bilingual teachers scored 107 responses of fourth- and fifth-grade Spanish-speaking ELLs to mathematics items administered in…

This study compares the dependability of four classroom assessment scoring methods. Generalizability theory (G) and alternative decision (D) are used to measure the results of students' classroom assessment scores and compare the results of the four scoring methods on variability of rater by person variance and the level of G and D coefficients…

The purpose of this study was to examine the effect of three ventilation conditions (i.e., normal, regimented, and no-ventilation) on the reproducibility of bioimpedance scores in humans for the forearm and trunk segments. One hundred able-bodied North American men and women, from 18 to 71 years of age, volunteered as participants. The…

The use of oral reading fluency (ORF) passages within a Response to Intervention (RTI) framework is examined. Significant limitations within the current ORF research are discussed. The passage equivalency and readability scores for DIBELS Next, AIMSweb, and a school district's curriculum's ORF passages are evaluated using Generalizability Theory…

Although direct observation is one of the most frequently used assessment methods by school psychologists, studies have shown that the number of observations needed to obtain a dependable estimate of student behavior may be impractical. Because direct observation may be used to inform important decisions about students, it is crucial that data be…

Using generalizability (G-) theory, this study examined the accuracy and validity of the writing scores assigned to secondary school ESL students in the provincial English examinations in Canada. The major research question that guided this study was: Are there any differences between the accuracy and construct validity of the analytic scores…

Parenting style, as a widely studied topic, has been used by researchers and educators in the US to predict students' academic achievements. Despite its theoretical and practical significance, no much work has been conducted to test the generalizability of parenting research framed in the Western culture to the Chinese population. Parenting styles…

Researchers have been making use of ecological momentary assessment (EMA) and other study designs that sample feelings and behaviors in real time and in naturalistic settings to study temporal dynamics and contextual factors of a wide variety of psychological, physiological, and behavioral processes. As EMA designs become more widespread,…
