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…

The process of decision-making is a multifaceted cognitive endeavor encompassing various cognitive, emotional, psychological, and social processes. It empowers individuals to select from a range of alternatives. Its significance spans across age groups, impacting both adults and children, and the relevance of which goes beyond aiding learners in…

This study aimed to develop a valid and reliable measurement tool to determine the anxiety levels of parents with gifted children. The participants were selected using a convenient sampling method. The sample of this study consisted of 550 parents of gifted middle school students attending 12 Science and Art Centers throughout Turkey in the…

Background/purpose: The purposes of this research are to develop a reliable and valid assessment tool for measuring systems thinking skills in upper primary students in Thailand and to establish a normative criterion for evaluating their systems thinking abilities based on educational standards. Materials/methods: The study followed a three-phase…

The aim of this study is to develop a measurement tool to measure the listening/watching attitudes of pre-service teachers. 387 pre-service teachers were administered the scale, and its validity and reliability studies were conducted by exploratory factor analysis, internal consistency measurement, and confirmatory factor analysis. EFA revealed…

Item analysis is performed by developers as an integral part of the scale development process. Thus, items are excluded from the scale depending on the item analysis prior to the factor analysis. Existing item discrimination indices are calculated based on correlation, yet items with different response patterns are likely to have a similar item…

The purpose of the study is to validate the 54-item Fitness Switching Costs Scale (FSCS). The FSCS consists of a third-order formative construct with four second-order formative constructs and 11 first-order reflective constructs. Although there was support for the reliability and validity of higher-order constructs, validity of the 11 first-order…

Although examining teachers' various areas of knowledge in classroom practices has attracted considerable attention during recent decade, a short multidimensional questionnaire to assess the interactions of the knowledge domains with teachers' technological knowledge is unavailable in the literature. Thus, this research presents a self-assessment…

Self-regulation skill is the ability of an individual to plan, monitor, evaluate, and modify their learning process when necessary. It is highly important in foreign language learning because learning a language requires long-term motivation, discipline, and a strategic approach. This study aims to determine the level of high school students' use…

This study focuses on developing and validating a questionnaire to assess the integration of ICT by EFL teachers in higher education settings in Vietnam. Twenty EFL teachers from three language institutes participated in semi-structured interviews, generating 20 questionnaire items. Qualitative content analysis of the interview data provided…

Clear and rigorous quantum reasoning is needed to explain quantum physical phenomena. As pillars of true quantum physical explanations, we suggest specific quantum reasoning derived from quantum physical key ideas. An experiment is suggested to support such a quantum reasoning, in which a quantized radiation field interacts with an optical beam…

The Big Three Perfectionism Scale (BTPS) was created to integrate different aspects of perfectionism, including the newly conceptualized concept of narcissistic perfectionism. The goal of our two studies (N = 1341) was to examine the psychometric properties of the Polish adaptation of the BTPS, supporting the validity and portability of the…

Engineering lacks quantitative measures of racism and sexism in engineering graduate education. Racial and gendered disparities in participation, persistence, and experience combined with qualitative evidence indicate that discrimination interferes with marginalized students' well-being and degree completion. The Discrimination in Engineering…

With the emerging trend of researching teacher identity from using qualitative approach to adopting quantitative or mixed-methods approach, it is essential and significant to develop instruments for measuring this construct. This paper reports on the development and validation of a measurement tool, the English Teacher Identity Measure (ETIM).…

In exploratory factor analysis, although the researchers decide which items belong to which factors by considering statistical results, the decisions taken sometimes can be subjective in case of having items with similar factor loadings and complex factor structures. The aim of this study was to examine the validity of classifying items into…
