This study aimed to develop an instrument with acceptable validity and reliability for assessing two key aspects among science teachers: their self-efficacy in teaching science through an integrated STEM approach (STSIS) and their outcome expectancy when employing this approach (OETSIS), which we refer to as TSTSIS. We administered this tool to…

Phonological awareness plays a key role in learning to read; therefore, its assessment has received a lot of attention. Research in the domain of phonological awareness has been characterized by attempts to develop reliable and valid assessment tools for diverse populations. Over the past few decades, phonological awareness assessment has gone…

This study examines the self-perceptions of Indonesian primary education teachers as transformational leaders. A quantitative survey was conducted with 400 randomly selected teachers from Lampung Province, Indonesia to assess their transformational leadership (TL) practices using the Transformational Teaching Questionnaire (TTQ) adapted and…

Accurate measurement of wisdom is the cornerstone of wisdom research. To provide a representative reference for the reliability level and moderating factors of various wisdom self-rating scales, we carried out a reliability generalization meta-analysis of Chinese and English references retrieved from 2004 to 2023. A total of 149 articles were…

The aim of the study was to investigate the reliability and validity of the timed up & go (TUG) test and the 30-s sit-to-stand (30-s STS) test performed via tele-assessment in ambulatory patients with stroke. Sixty-one patients with chronic stroke were included. For reliability, test-retest and inter-rater reliability were determined. For…

A number of familiarization trials are needed for reliable measurement, particularly for inexperienced subjects. Researchers have studied and developed familiarization protocols that vary by exercise and study population. The pace of familiarization and fatigue may be an individual-level characteristic, so a population-level protocol may not fit…

The aim of this paper is to measure and compare the quality of services provided by higher education institutions in the Czech Republic and Vietnam. It is not the sheer volume of services offered, but their quality, which matters as a strategic tool enhancing the competitiveness in the tertiary education market. Feedback from student-clients is…

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 logistic and confined exponential curves are frequently used in studies of growth and learning. These models, which are nonlinear in their parameters, can be estimated using structural equation modeling software. This paper proposes a single combined model, a weighted combination of both models. Mplus, Proc Calis, and lavaan code for the model…

Test score comparability in international large-scale assessments (LSA) is of utmost importance in measuring the effectiveness of education systems and understanding the impact of education on economic growth. To effectively compare test scores on an international scale, score linking is widely used to convert raw scores from different linguistic…

Creativity is highly valued in both education and the workforce, but assessing and developing creativity can be difficult without psychometrically robust and affordable tools. The open-ended nature of creativity assessments has made them difficult to score, expensive, often imprecise, and therefore impractical for school- or district-wide use. To…

Using a newly created teacher evaluation instrument, Inter-rater Reliability (IRR) analyses were conducted on four teacher videos as a means to establish instrument reliability. Raters included 42 principals and assistant principals in a southern US school district. The videos used spanned the teacher quality spectrum and the IRR findings across…

This study attempted to create a valid and reliable instrument to measure how gifted children perceive the gifted label and others' perceptions of giftedness. We recruited a total of 300 gifted Turkish children (59.3% males; 40.7% females) aged 10-13 years (M = 11.4, SD = 0.99) to this validity and reliability study. For validity concerns, we…

Video data analysis (VDA) represents an important methodological framework for contemporary research approaches to the myriad of footage available from cameras, devices, and phones. Footage from police body-worn cameras (BWCs) is anticipated to be a widely available platform for social science researchers to scrutinize the interactions between…

Single-case design is a research methodology that entails repeated measurement to assess the influence of an independent variable on a dependent variable over time. Data collected in this manner are regularly analyzed using visual analysis of data displayed in a linear graph. Although there is agreement regarding critical elements of visual…
