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…

The purpose of this two-part study is to evaluate methods for multiple group analysis when the comparison group is at the within level with multilevel data, using a multilevel factor mixture model (ML FMM) and a multilevel multiple-indicators multiple-causes (ML MIMIC) model. The performance of these methods was evaluated integrally by a series of…

The research and practice of social scientists who work in a myriad of different specialty areas involve developing and validating scores on instruments as well as evaluating the psychometric properties of existing instrumentation for use with research participants. In this article, the author introduces The MEASURE Approach to instrument…

In this article, we develop the revised and short versions of the pseudoscientific belief scale through two empirical studies (N = 4154). This revision is motivated by the excessive length of the scale, as well as by consistent observations of poor item loadings across several studies. Exploratory factor analysis in Study 1 revealed 11 dispensable…

The present investigation aims to test the validity of scores on the math homework purpose scale (MHPS) for high school students. Factorial results found that the MHPS contained three subscales: academic purpose, self-regulatory purpose, and approval-seeking purpose. Furthermore, the MHPS had a sufficient level of measurement and latent factor…
