Academic procrastination, the tendency to delay academic tasks without reasonable justification, has significant implications for students' academic performance and overall well-being. To measure this construct, numerous scales have been developed, among which the Academic Procrastination Scale (APS) has shown promise in assessing academic…

Introduction/Background: In 2016, the Adolescent Motor Competence Questionnaire (AMCQ) was developed in Australia. The AMCQ was developed to assess perceived motor competence in adolescents between the ages of 12 and 18 years. The 26 items represent four factors: participation in physical activity and sports, activities of daily living, public…

Experienced discrimination based on identity and appearance (or discrimination experience) is critical to assess among the college student population given its relationship to six key components of the college student experience. Investigating this variable requires the use of a psychometrically sound scale that demonstrates adequate validity and…

There are growing expectations in Australia and internationally that school educators will engage with and use research to improve their practice. In order to support educators to respond to such expectations, there is a need to be able to accurately assess the levels of educators' research engagement. At present, however, few psychometrically…

Self-determination theory (SDT) is a significant theoretical framework for investigating and comprehending student learning and motivation, which are crucial aspects of physical education. The purpose of this study is to identify the reliability and validity of the Malay language version of SIMS-14 items, as well as to determine the effect of…

The Science Teaching Efficacy Belief Instrument A (STEBI-A; Riggs & Enochs, 1990 in Science Education, 74(6), 625-637) has been the dominant measurement tool of in-service science teacher self-efficacy and outcome expectancy for nearly 30 years. However, concerns about certain aspects of the STEBI-A have arisen, including the wording,…

Many researchers have separately developed instruments to measure environmental characteristics such as attitudes, values, and knowledge. However, there is no instrument used to measure all these aspects in one comprehensive instrument. This study is meant to develop and validate a green character instrument which reveals student behavior and…

Rasch Analysis suggested the Lakaev Academic Stress Response Scale-1 (LASRS-1) would benefit from refinement by the addition of items and changes to the wording of other items. It was named the LASRS-2 and contained Four Domains (Affective, Behavioral, Cognitive, and Physiological). Rasch Model Analysis tested construct validity and internal…

The aim of this study is to develop a valid and reliable measurement tool that measures critical thinking skills of university students. Pamukkale Critical Thinking Skills Scale was developed as two separate forms; multiple choice and open-ended. The validity and reliability studies of the multiple-choice form were constructed on two different…

The What Is Happening In this Class? (WIHIC) questionnaire is a multidimensional measure for assessing the classroom learning environment based on student perspectives. The purpose of this study was to validate an Indonesian version of WIHIC and to assess the instrument's psychometric properties by using confirmatory factor analysis (CFA) and the…

Digital competence is critical for university students to adapt to and benefit from digitally enhanced learning. Prior studies on its measurement mostly focus on educators and relied on factor analyses. However, there is a lack of valid and convenient tools to measure university students' digital competence. This study aimed to develop a digital…

Metacognition inventory supports increased awareness and self-control to improve student's academic success, including physics. However, there are limitations to revealing the Physics Metacognition Inventory (PMI), especially in Indonesia. This study aims to explore and evaluate the psychometric properties of PMI. This survey research has involved…

The accurate assessment of analytical thinking in physics, particularly in magnetism, poses substantial challenges due to the limitations of conventional tools in measuring higher-order cognitive skills. This study aimed to validate an analytical skills test in physics, based on Bloom's Revised Taxonomy, with an emphasis on the dimensions of…

Researchers design diagnostic assessments to measure students' knowledge structures and processing skills to provide information about their cognitive attribute. The purpose of this study is to determine the instrument's validity and score reliability, as well as to investigate the use of classical test theory to identify item characteristics. The…

This study examined the psychometric properties of the Ego Resiliency Scale-Revised (ER89-R). Though support exists for a multidimensional conceptualisation using classical test theory approaches (i.e., a higher-order model comprising Openness to Life Experiences and Optimal Regulation factors), this measure has not been subjected to Rasch…
