Sample size and statistical power are important factors to consider when planning a research synthesis. Power analysis methods have been developed for fixed effect or random effects models, but until recently these methods were limited to simple data structures with a single, independent effect per study. Recent work has provided power…

Social scientists have long agreed that satisficing behavior increases error and reduces the validity of survey data. There have been numerous reviews on detecting satisficing behavior, but preventing this behavior has received less attention. The current narrative review provides empirically supported guidance on preventing satisficing by…

Purpose: Primary education (PE) forms the foundation of high-quality education systems, but it is often underestimated. This paper aims to develop and empirically validate a measurement instrument to study the current stage of total quality management (TQM) implementation in PE. Design/methodology/approach: This study developed a seven-dimensional…

With the advent of big data and advances in technology, psychological assessments have become increasingly sophisticated and complex. Nevertheless, traditional psychometric issues concerning the validity, reliability, and measurement bias of such assessments remain fundamental in determining whether score inferences of human attributes are…

Background and Aims: A literature review of both Eastern and Western literature regarding families of children with autism spectrum disorder (ASD) revealed limited empirical research that examines ASD in China. Furthermore, most research in this area comes from a deficit model and there is a lack of research that comes from a strengths background.…

About 45 R packages to analyze data using item response theory (IRT) have been developed over the last decade. This article introduces these 45 R packages with their descriptions and features. It also describes possible advanced IRT models using R packages, as well as dichotomous and polytomous IRT models, and R packages that contain applications…

The goal of this paper is to examine the psychometric properties of a live-coded behavioral measure of joint attention, the "Attention-Following and Initiating Joint Attention Protocol" (JA Protocol), in order to assist researchers and clinicians in identifying when this measure may meet their joint attention assessment needs. Data from…

School climate measurement is a long-standing topic in educational research. This review article provides an overview and appraisal of school climate measures published between 2003 and 2013 in scientific journals. A search for published school climate instruments for secondary school students was made in three databases. Twelve articles meeting…

This is the first book to gather and address what we have learned about the impacts and challenges of data-intensive teacher evaluation systems--a defining characteristic of the current education policy landscape. Expert researchers and practitioners speak to what we know (and what remains to be known) about evaluation measures themselves, the…

This guide is designed to help researchers make sure that their research reports include enough information about study measures so that readers can assess the quality of the study's methods and results. The guide also provides examples of write-ups about measures and suggests resources for learning more about these topics. The guide assumes…

The reliability of a new scale to assess Autistic Disorder, Pervasive Developmental Disorder, Not Otherwise Specified (PDD-NOS), and Asperger's Disorder in children was examined. Parents or other caregivers rated symptoms of 207 children between 2 and 16 years of age. The scale, which had 40 items in the final version, correlated highly with…

Research has consistently shown that principal leadership matters for successful schools. Evaluating principals on the behaviors shown to improve student learning should be an important leverage point for raising leadership quality. Yet principals are often evaluated with the use of instruments with no theoretical background and little, if any,…

This study described the process of developing and validating the College Chemistry Self-Efficacy Scale (CCSS) that can be used to assess college students' beliefs in their ability to perform essential tasks in chemistry. In the first phase, data collected from 363 college students provided evidence for the validity and reliability of the new…

Describes pilot studies of the Edinburgh Extended Glasgow Outcome Scale (EEGOS), designed to retain the advantages of the GOS (a measure commonly used in head injury research) but to allow comparison of recovery patterns in behavioral, cognitive, and physical function. Studies show that the interrater reliability of the EEGOS is comparable to that…

In this study, self-reports of 34 individuals with developmental disabilities (DD) were compared with proxy ratings from family and providers. Correlations between the ratings of individuals with DD and the proxy raters were low, as were the correlations between family members and providers. In all scales except "cognition," the individual with DD…
