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…

Despite the high demand for STEM (science, technology, engineering, and mathematics) professionals, the STEM talent pipeline continues to leak. A framework of STEM identity could provide insight into why and to what extent individuals engage in STEM-related activities. The present study describes the process of developing and validating an…

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…

Purpose: The purpose of this research paper is to adapt and validate a useful instrument to diagnose the knowledge, attitudes, behaviours and intention to participate (KABIP) towards Sustainable Development Goals (SDGs) in higher education institutions (HEIs) from the public administration in developing countries. Design/methodology/approach: The…

Using item response theory, we examined the psychometric properties of scores on the Trauma-Informed Practice Scales -- Supervision Version (TIPS-SV) -- a unidimensional measure of supervisees' perceptions of their supervisors' adherence to trauma-informed supervision -- in a sample of 312 supervisees. Implications for research and supervision…

Diagnostic tests have been developed previously to measure algebraic thinking skills; however, the tests do not specifically address algebraic problem-solving. Thus, an Algebraic Thinking Test (ATT) Instrument was developed to measure algebraic thinking skills in problem-solving involving linear equations. ATT comprises nine open-ended questions…

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:…

This study was conducted to: 1) ascertain the validity, reliability, and feasibility of a module based on the socioscientific issue approach and design thinking model (SIA-DT), and 2) assess its effects on the entrepreneurial creative thinking (ECT) in STEM education. The first phase of ECT module validation was conducted with the assistance of…

This study aims to develop and validate a scale measuring emergency remote teaching self-efficacy of teachers. The scale was given to 190 teachers during the scale development stage. Four factors were extracted as a result of exploratory factor analysis. The final 24-item version of the scale was tested on 234 teachers during the scale validation…

This study focused on the development and validation of the Sense of Online Community Scale (SOCS), which includes 28 Likert-type scale items across six subscales: (1) program community; (2) program academic activities; (3) program social activities; (4) institutional academic activities; (5) institutional social activities; and (6) affiliation.…
