We examined the performance of coefficient alpha and its potential competitors (ordinal alpha, omega total, Revelle's omega total [omega RT], omega hierarchical [omega h], greatest lower bound [GLB], and coefficient "H") with continuous and discrete data having different types of non-normality. Results showed the estimation bias was…

The idea of sources other than the test-takers' knowledge leading to different results on high-stakes tests was the motif based on which the present investigation was initiated on the probable sources of unreliability of a test. For this purpose, the researchers went through a thorough literature review with the aim to identify the issues to be…

The aim of this study was to develop and validate a psychometrically-sound instrument to assess students' perceptions about class cohesion. Two studies were conducted. In Study 1, four steps were established: (1) development of the Class Cohesion Questionnaire (CCQ); (2) item selection; (3) item compression; and (4) exploration of psychometric…

This study sought to develop a valid and reliable measurement tool that measures the perceptions of behavioral dispositions in determining the high school preferences of 8th grade students. The study population consisted of 26,906 eight graders in public and private secondary schools located in the city centres of Aydin and Denizli, Turkey. The…

The Social Justice Scale (SJS) and various subscales were studied on a sample of 414 human services university undergraduates. Internal consistency ([alpha] = 0.93), discriminant validity, and response bias were adequate. The 4-factor model demonstrated an excellent fit. Implications were discussed for use of the SJS in practice and research.

This study attempted to conceptualise and measure learners' perceptions of their collaborative problem-based learning and peer assessment strategies in a technology-enabled context. Drawing on the extant literature, we integrate collaborative, problem-based and peer assessment learning strategies and propose a new model, the collaborative…

Awareness of informational text structures is related to reading comprehension and varies according to characteristics of readers and texts. The purpose of this study was to develop and refine a measure of text structure awareness, the Text Structure Identification Test (TSIT), by investigating its internal consistency reliability and construct…

Effectiveness of motor interventions depends not only on learning content but also on the used teaching strategies. However, little is known regarding the application of teaching strategies in clinical practice. This study aimed to develop and assess psychometric properties of a new Dutch observational instrument to document teaching strategies:…

Purpose: A sublime social attitude ("brahmavihara") has been identified as a crucial aspect of Buddhist Education (BE) for fostering prosocial behavior. Therefore, this study aims to construct and establish the validity of a sublime social attitude scale for prospective teachers of BE, as well as to detect social desirability bias (SDB).…

This quantitative study aims to explore the validity of Donohoo et al.'s (2020) Enabling Conditions for Collective Teacher Efficacy Scale (EC-CTES) for fostering collective efficacy in schools and evaluate its relationship to measures of collective teacher efficacy. The instruments used for this study include the EC-CTES, the Collective Efficacy…

With the increasing significance of technology use in both daily life and education, the digital native assessment scale (DNAS) [developed by Teo, T. (2013). An initial development and validation of a Digital Natives Assessment Scale (DNAS). Computers & Education, 67, 51-57.] has been widely used as a tool to investigate the digital nativeness…

Purpose: Recent studies have shown that an acoustic measure, relative fundamental frequency (RFF), has potential for the assessment of excessive laryngeal tension and vocal effort associated with functional and neurological voice disorders. This study presents an analysis of the test-retest reliability of RFF in individuals with healthy voices and…

Curated undergraduate research experiences have been widely used at colleges and universities for decades to build student interest, technical preparation, and confidence in the pursuit of scientific careers. Educators often employ standardized survey instruments to evaluate learning outcomes for research experiences, but many of these assessments…

Background/purpose: Writing is an essential skill for EFL learners, and the development of flawless writing proficiency in English is the intended learner outcome of every writing course in an EFL program. Development of flawless writing skills involves perfection in orthography (spelling, punctuation, capitalization), grammaticality and syntax,…

Background: Current UK measures of early spoken language comprehension require manipulation of toys and/or verbal responses and are not accessible to children with severe motor impairments. The Computer-Based Instrument for Low motor Language Testing (C-BiLLT) (originally validated in Dutch) is a computerized test of spoken language comprehension…
