Disengagement is considered a significant component that affects the success, participation, and activity of the students in the online course. Reviewing the literature revealed the lack of a measurement tool for assessing students' disengagement in online courses. This study aimed to develop a scale that examines student disengagement in online…

Coefficient omega indices are model-based composite reliability estimates that have become increasingly popular. A coefficient omega index estimates how reliably an observed composite score measures a target construct as represented by a factor in a factor-analysis model; as such, the accuracy of omega estimates is likely to depend on correct…

Purpose: This study aims to develop and validate a scale to measure Teacher Entrepreneurial Behavior (TEB), which encapsulates the behaviors teachers employ to identify and amplify innovation in schools. TEB are catalysts for innovation, navigating their peers through risks and building trust, which empowers the collective to transcend structural…

Bullying is a form of school violence that has recently received the attention of school psychologists. One of these problems that exists in almost all schools is the phenomenon of school bullying. The aim of this study is to examine the psychometric reliability and validity of the Participant Role Scale in bullying in Persian and compare the…

The consistency of psychometric properties across waves of data collection provides valuable evidence that scores can be interpreted consistently. Evidence supporting the consistency of psychometric properties can come from using a longitudinal extension of item factor analysis to account for the lack of independence of observation when evaluating…

This paper presents a new astronomy self-efficacy instrument, composed of two factors; one relating to learning astronomy content, which we call astronomy personal self-efficacy, and the other relating to the use of astronomical instrumentation, specifically the use of remote robotic telescopes for data collection. The latter is referred to as the…

The Bracken School Readiness Assessment (BSRA) has been used in large studies such as the Millennium Cohort Study (MCS). Important conclusions might be done regarding its reliability for the prediction of children's school readiness taking advantage of such large-scale evaluation. Although BSRA has being largely used, few are the studies at…

The aim of the present research is to develop a psychometrically qualified measurement tool to find out the emotional authenticity levels of individuals. Taking roots from the rational approach, 53 items were written by the researchers in line with the relevant literature review and the opinions of the experts, and the expert opinion form prepared…

This note is concerned with the benefits that can result from the use of the maximal reliability and optimal linear combination concepts in educational and psychological research. Within the widely used framework of unidimensional multi-component measuring instruments, it is demonstrated that the linear combination of their components that…

This study examined the psychometric properties of the Career Adapt-Abilities Scale in a Lebanese sample. The study includes 236 Lebanese citizens (54.2% women; M[subscript age] = 30.14). Confirmatory factor analyses indicated that a hierarchical model yielded a good fit, with the CAAS measuring four distinct dimensions that can be combined in a…

Purpose: Developing an enabling bureaucratic structure for school organization has been an important aim of education governance reforms in China, like many societies across the globe, since the 1990s. However, there is a lack of valid measures to investigate the extent to which the Chinese education governance reforms facilitate the development…

Although parallel analysis has been found to be an accurate method for determining the number of factors in many conditions with complete data, its application under missing data is limited. The existing literature recommends that, after using an appropriate multiple imputation method, researchers either apply parallel analysis to every imputed…

This article reports the development and validation of the new Process and Outcomes from Service-Learning (POSL) questionnaire, a self-report measure that assesses students' service-learning experiences as well as their attainment of a comprehensive set of intended service-learning outcomes. The study involved three phases: (a) construct…

As one of the 21st-century skills, self-directed learning (SDL) has received widespread attention and has become an essential research topic in education. In this study, we examined the psychometric properties of the SDL scale (SDLS) (Lounsbury et al., 2009) with a sample of 408 Chinese undergraduates. Previous research on Chinese students has…

Engaging in design thinking activities has been increasingly viewed as important for the craft of teaching for early childhood practitioners. However, reliable and valid measurements for this are lacking. As such, this research aims to develop and validate a design thinking engagement scale (DTES) to assess teachers' engagement in design thinking.…
