This study examined psychometric properties of scores on the Depression Anxiety Stress Scales-21 (DASS-21) with a nonclinical sample of senior games athletes (N = 383). Information on the internal reliability, item-scale correlations, structural validity, and concurrent validity of the DASS-21 scores is provided to test its applicability to senior…

With the exponential increase in the volume of data available in the 21st century, data literacy skills have become vitally important in work places and everyday life. This paper provides a systematic review of available data literacy assessments targeted at different audiences and educational levels. The results can help researchers and…

Science education in primary school is critical for establishing a comprehensive understanding of the nature of science. Students with positive attitudes towards science courses are more likely to achieve academic success. Measuring and fostering positive attitudes is essential for effective instructional planning. This study aimed to develop a…

Although an abundance of research has discussed the importance of Universal Design for Learning (UDL), there is little research on how UDL may be used in syllabus construction. The authors developed and validated the UDL Syllabus Scale (UDLSS), which evaluates higher education instructors' ability to design a syllabus using UDL principles. Over…

Within educational and social discourses, the term 'inclusion' has various meanings. In both research and practice, there is no official definition of inclusion. Nevertheless, subjective definitions affect pedagogical acts. We developed the Definitions of Inclusion Questionnaire ["Fragebogen zur Erfassung subjektiver Definitionen von…

In order to support research on school effectiveness, there is a need for valid and reliable instruments to assess policymaking capacities of schools. Increasingly, policymaking is seen as a shared responsibility of the entire pedagogical team of a school. In this article, data were analysed from a sample of 1,696 (care) teachers coordinators and…

Computational thinking (CT) has permeated primary and early childhood education in recent years. Despite the extensive effort in CT learning initiatives, few age-appropriate assessment tools targeting young children have been developed. In this study, we proposed Computational Thinking Test for Lower Primary (CTtLP), which was designed for lower…

The current study aimed to measure preservice teachers' skills in implementing pedagogical model of collaborative problem solving (CPS) using a more advanced and novel human-to-agent computerized assessment instrument. By doing so, a framework with three major skills in the implementation of CPS and four major individual problem-solving processes…

This paper summarizes the development and validation of the Revised Affirmative to Problem Parenting Scale (R-APPS) using a sample of 643 adults with disabilities. Results of exploratory factor analysis, confirmatory factor analysis, correlations, and reliability estimates reveal sound psychometric structure for a 4-factor scale distinguishing…

This paper presents a new method for accurately measuring the vocabulary size of second language (L2) learners. Traditional vocabulary size tests (VSTs) are limited in capturing a tester's vocabulary and are often population-specific. To overcome these issues, we propose an intelligent vocabulary size measurement method that utilizes massive robot…

The aim of the study was to evaluate the extended version of the Problem-Solving Inventory (PSI) via an online learning setting known as the Online Problem-Solving Inventory (OPSI) through the lens of Rasch Model analysis. To date, there is no extended version of the PSI for online settings even though many researchers have used it; thus, this…

The aim of this study is threefold: (1) to present a valid and reliable scale in the framework of the Technology Acceptance Model; (2) to reveal factors affecting pre-service science teachers' intentions to use technology-based STEM; (3) to examine the effect of technology-based STEM education training on pre-service science teachers' perceived…

This study aimed to examine the psychometric properties of the Turkish version of Sosu Critical Thinking Disposition Scale (TV-CTDS). The data were gathered from two independent samples consisting of undergraduate and graduate students from four different universities in the Black Sea region of Turkey. After the translation procedure, the…

The challenges experienced in measurement and evaluation during the distance education process among student and instructor groups are discussed in the study. A qualitative meta-synthesis method is used in this research. Twenty studies were included in the meta-synthesis. The challenges experienced by the instructors are program utilization,…

The present research emphasizes the role of learning in response changes to infection threats and suggests a new instrument. This preliminary study aims to develop a brief tool (SITS: Sensitivity to Infection Threats Scale) that measures individuals' health sensitivity to infection threats. The present research utilized the Brief Symptom…
