In light of the fact that technology teachers' understandings of the nature of technology (NoT) determine students' perceptions of NoT, this study turned attention to technology teachers, and developed a comprehensive theoretical instrument for assessing their understandings of NoT. The theoretical framework of NoT was proposed using a…

Effective classroom management methods are well known, but effective ways of managing classes of beginner teachers remain elusive. Classroom management refers to the wide range of skills and techniques that teachers use to ensure that classes are conducted without destructive student behavior. The present study is applied nonexperimental research.…

In STEMNET's report, 76% of 500 teachers interviewed stated that joining the STEM Club increased students' ability to solve real-world problems. This study aims to develop a valid and reliable measurement tool for evaluating STEM clubs. The research sample consisting of 149 teachers who carry out STEM club activities in schools in Turkey was…

The Fundamental Concepts for Organic Reaction Mechanisms Inventory (FC-ORMI) is a concept inventory with most items in a two-tier design in which an answer tier is followed by a reasoning tier. Statistical results provided strong evidence for the validity and reliability of the data obtained using the FC-ORMI. In this study, differential item…

Recent surveillance efforts indicate that 1 in 54 American children meet the criteria for Autism Spectrum Disorder (ASD), making it the fastest growing neurodevelopmental disorder in the U.S. Despite evidence that ASD can be reliably diagnosed as early as 24 months, the median age at ASD diagnosis in 2016 in the U.S. was 51 months. The CLEAR…

The Social Competence Observation Scale (SCOS) is an objective observational measure developed to assess the social performance of children with autism spectrum disorder (ASD). This paper describes development of the SCOS and results of initial testing of reliability and treatment sensitivity for a sample of 12 children, ages 4-6 years, with ASD.…

Simulations concerning the distributional assumptions of coefficient alpha are contradictory. To provide a more principled theoretical framework, this article relies on the Fréchet-Hoeffding bounds, in order to showcase that the distribution of the items play a role on the estimation of correlations and covariances. More specifically, these bounds…

Purpose: Education for Sustainable Development (EDS) has highlighted the need to generate instruments to assess the sustainability competencies of different populations. In this regard, Physical Education (PE) has been recognized as a subject with unique characteristics that allow students to develop competencies that favor sustainability.…

In recent years, computational thinking has been considered as one of the 21st century skills that all students should have. Researchers emphasize the importance of determining and developing students' computational thinking levels from the earliest possible age. However, no measurement tool has been found in the literature that aims to reveal the…

Student engagement is a critical component of e-learning, which became an important focus for most academic institutions during the COVID-19 pandemic. University students' engagement is measured using various scales with different subscales. This study aimed to evaluate the psychometric properties of the Persian version of the University Student…

This study is an attempt to develop a reliable and valid measurement tool to measure secondary school students' attitudes towards metaverse use. Therefore, the study reported the analyses related to metaverse attitude scale (MVAS). The content validity of the scale was ensured by an expert's view, and Exploratory Factor Analysis (EFA) and…

Teacher agency is a pivotal element of professionalism and second/foreign language (L2) education. However, its role in L2 assessment has remained under-researched. Part of this negligence is due to the absence of a validated questionnaire to measure the construct and its underlying components. To address this gap, drawing on the ecological…

This study aimed to refine and validate a Mechatronic System Usability Evaluation (MSUE) questionnaire. A total of 626 users were selected using random sampling, from the area of West Thessaloniki, Greece. The validity of the questionnaire were tested with the content and construction validity method. The reliability of the MSUE questionnaire…

School-wide positive behavior interventions and supports (SWPBIS) is widely implemented across the United States. Evidence suggests that SWPBIS, when implemented with fidelity, has a significant and positive impact on schools, including lower suspensions and higher reading and mathematics achievement. A critical component of this research is…

The purpose of this study was to adapt the computational thinking scale developed by Tsai, Liang and Hsu (2021) into Turkish in order to determine the computational thinking skill levels of secondary school students according to such basic elements defined by Selby and Woollard (2013) as abstraction, decomposition, algorithmic thinking, evaluation…
