A direct approach to point and interval estimation of Cronbach's coefficient alpha for multiple component measuring instruments is outlined. The procedure is based on a latent variable modeling application with widely circulated software. As a by-product, using sample data the method permits ascertaining whether the population discrepancy…

A critical discussion of the assumption of uncorrelated errors in classical psychometric theory and its applications is provided. It is pointed out that this assumption is essential for a number of fundamental results and underlies the concept of parallel tests, the Spearman-Brown's prophecy and the correction for attenuation formulas as well as…

Background: Intelligibility is a speaker's ability to convey a message to a listener. Including an assessment of intelligibility is essential in both research and clinical work relating to individuals with communication disorders due to speech impairment. Assessment of the intelligibility of spontaneous speech can be used as an overall…

Subscores are often used to indicate test-takers' relative strengths and weaknesses and so help focus remediation. But a subscore is not worth reporting if it is too unreliable to believe or if it contains no information that is not already contained in the total score.

Abilities in scientific thinking and reasoning have been emphasized as core areas of initiatives, such as the Next Generation Science Standards or the College Board Standards for College Success in Science, which focus on the skills the future will demand of today's students. Although there is rich literature on studies of how these abilities…

This study investigates Spolsky's conception of language policy as the amalgam of language beliefs, language practices and language management. To the best of our knowledge, no quantitative evidence has ever been produced for his theoretical model. The current paper addressed this void, albeit specifically in the domain of Early Childhood Care and…

Score interchangeability of Computerized Fixed-Length Linear Testing (henceforth CFLT) and Paper-and-Pencil-Based Testing (henceforth PPBT) has become a controversial issue over the last decade when technology has meaningfully restructured methods of the educational assessment. Given this controversy, various testing guidelines published on…

The purpose was to understand elementary bilingual and dual language (BDL) teachers' perspectives of science and engineering (S&E) teaching in Massachusetts and Puerto Rico with the goal of developing situated professional…

There is a dearth of research on hope in studies of second or foreign (L2) language learning. Therefore, the present research contributes conceptually to a deep understanding of hope for learning English as a foreign language and the ways it may be developed. To do so, an exploratory mixed-methods design was employed. Using in-depth interviews,…

This study aims to develop a standard scale by making the validity and reliability of the globalization survey developed for education faculties in the sample of sports sciences. A total of 878 people, including 81 academicians, 336 physical education and sports teachers, 118 trainers, and 343 sports sciences students, who were reached by a simple…

Because the pandemic exacerbated chronic absenteeism in many parts of the country, the need to understand how schools can improve student attendance has never been greater. Accordingly, this study breaks new ground by examining high schools' contributions to attendance after accounting for individual students' prior absenteeism and other…

This paper presents evidence of the score reliability, factor structure, criterion-related validity, and measurement equivalence of a web-based assessment of several important social and emotional competencies for children in fourth through sixth grades. The assessment, SELweb LE (Late Elementary), is designed to measure children's understanding…

Observation of counsellor skills through a one-way mirror, video or audio recording followed by supervisors and peers feedback is common in counsellor training.
