This study aimed to develop a valid and reliable measurement tool to determine the anxiety levels of parents with gifted children. The participants were selected using a convenient sampling method. The sample of this study consisted of 550 parents of gifted middle school students attending 12 Science and Art Centers throughout Turkey in the…

Recently, the question of which version of content knowledge (CK) is suitable for pre-service teacher (PST) development has gained prominence in teacher education research. A version of CK argued to be appropriate for science PST development has been introduced and referred to as teacher-related science content knowledge (TerSCK). This CK version…

Setting cut scores on (MSTs) is difficult, particularly when the test spans several grade levels, and the selection of items from MST panels must reflect the operational test specifications. In this study, we describe, illustrate, and evaluate three methods for mapping panelists' Angoff ratings into cut scores on the scale underlying an MST. The…

This study evaluates Large language models (LLMs)' performance on Chinese Postgraduate Medical Entrance Examination (CPGMEE) as well as the hallucinations produced by LLMs and investigate their implications for medical education. We curated 10 trials of mock CPGMEE to evaluate the performances of 4 LLMs (GPT-4.0, ChatGPT, QWen 2.1 and Ernie 4.0).…

Despite extensive studies on large language models and their capability to respond to questions from various licensed exams, there has been limited focus on employing chatbots for specific subjects within the medical curriculum, specifically medical neuroscience. This research compared the performances of Claude 3.5 Sonnet (Anthropic), GPT-3.5 and…

Education for Sustainable Development (ESD) serves as a key accelerator for achieving the Sustainable Development Goals (SDGs), emphasizing systems thinking as an essential competency that must be cultivated in the learning process. This study investigates students' systems thinking skills within the ESD framework through assessments on…

Organizational climate refers to the shared perceptions of behavior, the work environment, and daily life within an organization. This study is based on the assumption that, due to their differing roles and responsibilities in preschools, teachers and principals have significantly different perceptions of the organizational climate. The sample…

The aim of the following research was to investigate perceptions regarding the level of quality of services introduced at faculties in the Republic of Serbia, using a quantitative approach within exploratory research framework and applying statistical analysis methods.

This quantitative study was designed to determine whether the use of graphical aids in standardized mathematics testing is effective in lessening the achievement gap between English Language Learner (ELL) students and their non-ELL counterparts for middle-grade aged students. The data used for this study include data from 2,659 students and come…

This study offers an approach to test equating under the latent D-scoring method (DSM-L) using the nonequivalent groups with anchor tests (NEAT) design. The accuracy of the test equating was examined via a simulation study under a 3 × 3 design by two conditions: group ability at three levels and test difficulty at three levels. The results for…

Viable methods for the identification of item misfit or Differential Item Functioning (DIF) are central to scale construction and sound measurement. Many approaches rely on the derivation of a limiting distribution under the assumption that a certain model fits the data perfectly. Typical DIF assumptions such as the monotonicity and population…

Any time examinees have had access to items and/or answers prior to taking a test, the fairness of the test and validity of test score interpretations are threatened. Therefore, there is a high demand for procedures to detect both compromised items (CI) and examinees with preknowledge (EWP). In this article, we develop a procedure that uses item…

The Social Skills Improvement System-Teacher Rating Scale (SSIS-TRS) has been widely used to measure the social skills and behaviors of children and adolescents that are challenging. Studies examining the psychometric properties of the SSIS-TRS have been conducted, but the dimensional structure and item properties of the SSIS-TRS have not been…

This study addresses the topic of how anchoring methods for differential item functioning (DIF) analysis can be used in multigroup scenarios. The direct approach would be to combine anchoring methods developed for two-group scenarios with multigroup DIF-detection methods. Alternatively, multiple tests could be carried out. The results of these…

Purpose: To protect the environment and society, research on responsible behavior and personal values has increased. Values have been identified as important for understanding and predicting environmental preservation behaviors.
