Identifying creatively gifted students remains a challenging yet important task. Often, teacher rating scales are used to assess students' creative behaviors; however, the school environment may not always provide opportunities for students to demonstrate creative ability, making it challenging for teachers to observe students' creative potential.…

The Woodcock-Johnson-III cognitive in the adult time period (age 20 to 90 plus) was analyzed using exploratory bifactor analysis via the Schmid-Leiman orthogonalization procedure. The results of this study suggested possible overfactoring, a different factor structure from that posited in the Technical Manual and a lack of invariance across both…

An empirical evidence for independent samples of a population regarding measurement invariance implies that factor structure of a measurement tool is equal across these samples; in other words, it measures the intended psychological trait within the same structure. In this case, the evidence of construct validity would be strengthened within the…

The main aim of this study is to examine the effect of principals' transformational leadership on teachers' self-efficacy across 77 different Greek elementary and secondary schools based on a centralized education system. For the investigation of the above effect multilevel Structural Equation Modelling analysis was conducted, recognizing the…

This study assessed the validity and reliability of the Meyer, Shanahan, and Laugksch's Conceptions of Research Inventory using data collected from 227 undergraduate hotel management students in the Netherlands. The results of a series of exploratory and confirmatory factor analyses showed substantial empirical support for the five-factor…

Popular teamwork assessments have been strongly criticized on the grounds of poor psychometric properties and their disconnect with conceptual models of teamwork. These issues raise concerns with respect to our ability to evaluate efforts devoted to advancing teamwork in academia. We report the development of a teamwork assessment that builds on…

The aim of the present study was to determine the factor structure of the Positive Life Assets Scale (PLAS), a new measure to identify both internal and external life assets among high school students in Thailand, and to further examine the usefulness of the PLAS for a comprehensive, developmental, and strengths-based school and community…

Schools and education systems are being challenged to improve the evaluation of teacher professional development, yet there is a lack of practical tools for doing so. This article describes the development and validation of a new instrument to assess teachers' perceptions of the impact of professional development. This instrument, designed to be…

The present study examined the validity of the factor structure and invariance of the Controlling Teacher Behaviours Scale (CTBS) across two nations. Data were collected from Estonian (n = 453) and Lithuanian (n = 431) students using the multidimensional measure of teachers' controlling behaviours. Multi-sample confirmatory factor analyses showed…

The purpose of the first study was to develop and validate a new self-report survey used to determine the level of agentic, behavioral, cognitive, and emotional engagement of eighth and ninth grade boys and girls in physical education. Much of the development was driven by work completed by Reeve and Tseng (2011), and by Reeve (2013). Two hundred…

The aim of the study was describing the development and validation of students' perception on learning by questioning (LBQ) scale in physics. Research and Development (R & D) design was utilized in the research method. The number of senior high school students involved in the research were 224 students, composed of 95 boys (42.41%) and 129…

This study aims to develop a multidimensional 21st century skills scale for adolescent and early adulthood students in the 15-25 age group. The research was conducted with 660 high school, associate degree and undergraduate students. From the item pool created during the first stage of the study, 146 items were selected in line with expert…

This study explored two under-researched areas on students' attitudes towards science, that is, the structural models representing these attitudes and the role played by school bands in moderating the gender differences in such attitudes. The participants were 360 ninth graders in Hong Kong from 3 school bands. The structural equation modelling…

The first aim of this study was to explore the reliability and validity of the Turkish version of the Theoretical Orientation Profile Scale-Revised, and the second aim was to understand the relative influence of personal and professional variables on the choice of a guiding theoretical orientation among Turkish counselor trainees. Results showed…

The purpose of this study is to adapt the Survey of Attitudes Towards Statistics (SATS-36) for Estonian secondary school students in order to develop a valid instrument to measure students' attitudes within the Estonian educational context. The SATS-36 was administered to Estonian-speaking secondary school students before their compulsory…
