Researchers in second language (L2) and education domain use different statistical methods to assess their constructs of interest. Many L2 constructs emerge from elements/parts, i.e., the elements "define" and "form" the construct and not the other way around. These constructs are referred to as emergent variables (also called…

Measurement invariance holds when a latent construct is measured in the same way across different levels of background variables (continuous or categorical) while controlling for the true value of that construct. Using Monte Carlo simulation, this paper compares the multiple indicators, multiple causes (MIMIC) model and MIMIC-interaction to a…

This study focuses on creating a reliable and valid instrument to measure high school students' perceptions of academic challenge. The research is divided into four phases: qualitative analysis, item development, exploratory factor analysis (EFA), and validation. Initial data from college students' retrospective views and high school students'…

Teaching is a stressful profession with a high turnover rate. Schools and related institutions need to take more action to support teachers and keep teacher stress at a manageable level. The continued research and practical effort require measures to examine teachers' stress in a briefer and accurate manner. The Teacher Stress Scale is a recently…

This paper describes the design and evaluation of the Organic chemistry Representational Competence Assessment (ORCA). Grounded in Kozma and Russell's representational competence framework, the ORCA measures the learner's ability to "interpret," "translate," and "use" six commonly used representations of molecular…

The aim of this study is to develop a scale with high validity and reliability to determine teachers' classroom management approaches. For this purpose, the study was structured according to the survey design, one of the quantitative research designs. The sample of the study consists of teachers working in public schools affiliated to the Ministry…

Evaluating teacher AI competence levels and building effective, safe, and healthy learning environment are crucial steps in transitioning to AI-based education. Current established digital competence frameworks may indirectly address AI competence but often overlook the impact of AI on society, ethics, and assessment. Research on teacher AI…

Background/purpose: The purposes of this research are to develop a reliable and valid assessment tool for measuring systems thinking skills in upper primary students in Thailand and to establish a normative criterion for evaluating their systems thinking abilities based on educational standards. Materials/methods: The study followed a three-phase…

The problem of local item dependencies (LIDs) is very common in personality and attitude measures, particularly in those that measure narrow-bandwidth dimensions. At the structural level, these dependencies can be modeled by using extended factor analytic (FA) solutions that include correlated residuals. However, the effects that LIDs have on the…

The practice and measurement of multicultural counseling competencies have become key issues in the counseling field in recent years. The present study examines the psychometric properties of the California Brief Multicultural Competence Scale (CBMCS) with Turkish counselors and counselor candidates based on the participation of 284 individuals…

This study aimed to adapt the Plurilingual and Pluricultural Competence scale (PPC) to the Russian-speaking population and to assess its psychometric properties. Five hundred and sixty-four undergraduate students from Western, Central, and Caucasian regions of Russia and Kazakhstan participated in the study. Internal consistency, factorial,…

We used student surveys to assess changes in proficiency with integral calculus, calculus self-efficacy, and physics self-efficacy in a second semester course of introductory physics focused on electricity and magnetism. In addition to tracking the fraction of quantitative problems solved correctly on the calculus proficiency survey, we also used…

Self-efficacy and anatomical knowledge have been shown to be important in the development of medical students. Validated instruments designed to measure the construct of anatomical self-efficacy during the clinical years of medical school are limited. In this study, the Anatomical Self-Efficacy Instrument for Clinical Clerkships (ASEI-CC) was…

The Energy and Momentum Conceptual Survey (EMCS) is an instrument designed to assess students' understanding of key physics concepts in introductory mechanics. In this study, we applied a combination of classical test theory (CTT), item response theory (IRT), and exploratory factor analysis (EFA) to a dataset of over 10 000 students collected…

Scales assessing stressor exposure often fail to demonstrate adequate psychometric qualities, demonstrating low interitem reliability or complex factor structures, as would be expected, given that the majority of stressors are independent events. However, in large-scale mass crisis events, the stressors may be highly interrelated, indicating…
