School districts and states across the Regional Educational Laboratory Mid-Atlantic Region and the country as a whole have been modifying their teacher evaluation systems to identify more effective and less effective teachers and provide better feedback to improve instructional practice. The new systems typically include components related to…

Objectives: The present study examined the psychometric properties of the Chinese Virtues Questionnaire (CVQ). The reliability, factor structure, construct validity, and temporal stability of the inventory were examined. Method: A university student sample ("n" = 878) and a working adult sample ("n" = 153) were recruited.…

This study sought to evaluate whether a one-trial brief experimental analysis (OTBEA) would reliably and validly identify effective treatments to improve oral reading fluency for 6 elementary school students referred for reading problems. An OTBEA was conducted with each participant to assess the effects of skill- and performance-based treatment…

The examination of barriers in relation to college students' vocational choice and development is an important area of research, but the barrier of classism is relatively underexamined. This may be due to the deficiencies in measurement, so we describe herein the development of a new measure, the Experiences with Classism scale (EWCS). The EWCS…

In this paper, the author aims to provide novice researchers with an understanding of the general problem of validity in social science research and to acquaint them with approaches to developing strong support for the validity of their research. She provides insight into these two important concepts, namely (1) validity; and (2) reliability, and…

This study reports on the validation of the language domain subtest of a developmental assessment scale for Cantonese Chinese preschool children. Three hundred and seventy eight multi-stage randomly selected children between 3;4 and 6;3 years of age were tested on the 104-item subtest. Fifty-four of these children, spreading across three age…

Few classroom measures of English language proficiency have been evaluated for reliability and validity. This research examined the concurrent and predictive validity of an oral language test, titled A Developmental English Language Proficiency Test (ADEPT), and the relationship to the California English Language Development Test (CELDT) in the…

Developing normed treatment outcome measures is important to research addressing treatment effectiveness and to improved clinical care. The Preschool Outcome Questionnaire (POQ) is a new measure designed for use with preschool children aged two to six. Designed in collaboration with parents and clinicians, the POQ is brief, easy to administer,…

In a provocative and influential paper, Jesse Rothstein (2010) finds that standard value added models (VAMs) suggest implausible future teacher effects on past student achievement, a finding that obviously cannot be viewed as causal. This is the basis of a falsification test (the Rothstein falsification test) that appears to indicate bias in VAM…

Although reliability is essential to validity, most research on violence risk assessment tools has paid little attention to strategies for improving rater agreement. The authors evaluated the degree to which perceived subjectivity in scoring guidelines for items from two measures--the Psychopathy Checklist-Revised (PCL-R) and the Historical,…

The purpose of the current study was to evaluate the psychometric properties of alternative approaches to administering and scoring curriculum-based measurement for written expression. Specifically, three response durations (3, 5, and 7 minutes) and six score types (total words written, words spelled correctly, percent of words spelled correctly,…

Background: Sentence construction and syntactic organization are known to be poor in children with specific language impairments (SLI), but little is known about the way in which children with SLI approach language tasks, and static standardized tests contribute little to the differentiation of skills within the population of children with…

The purpose of the current study was to evaluate a screening instrument. The sample contained 496 elementary children from the rural southeast. Properties of the Teacher, Parent, and Student Forms of the Behavioral and Emotional Screening System were examined. Results indicated that all forms had high levels of internal consistency. There were low…

Identifying and understanding the foundational skills children need to participate effectively in formal schooling is an important objective for research in early childhood education. One component of school readiness is cognitive self-regulation (CSR). The question this study addresses is how to assess CSR with prekindergarten-aged children in a…

This work presents the evaluation and refinement of a chemistry attitude measure, Attitude toward the Subject of Chemistry Inventory (ASCI), for college students. The original 20-item and revised 8-item versions of ASCI (V1 and V2) were administered to different samples. The evaluation for ASCI had two main foci: reliability and validity. This…
