Large language models (LLMs), such as ChatGPT, are becoming increasingly prominent. Their use is becoming more and more popular to assist with simple tasks, such as summarizing documents, translating languages, rephrasing sentences, or answering questions. Reports like McKinsey's (Chui, & Yee, 2023) estimate that by implementing LLMs,…

The present study sought to examine the psychometric properties of new German, Portuguese, and Spanish versions of the Revised Short Form of the Physical Self-Inventory (PSI-S-"R"), and to contrast these properties against those from the original French version of this instrument. Participants (n = 1802) were 288 French youth, 177 German…

Test fairness is critical to the validity of group comparisons involving gender, ethnicities, culture, or treatment conditions. Detection of differential item functioning (DIF) is one component of efforts to ensure test fairness. The current study compared four treatments for items that have been identified as showing DIF: deleting, ignoring,…

This current study presents the effects of interactive computer simulations on students' performance and concept retention in the unit of chemical reactions. Purposive sampling was used to select four schools with a sample population of 320. The Achievement test on chemical reactions was developed, validated, and checked for reliability. The…

Learning geography in Indonesia philosophically aims to develop spatial literacy. Students must improve spatial literacy to form reasoning skills and apply spatial concepts in real life. Applying Gersmehl's spatial learning can improve students' spatial literacy through syntax arranged based on spatial aspects. The use of google earth helps…

We compared the influence of open-book extended duration versus closed book time-limited format on reliability and validity of written assessments of pharmacology learning outcomes within our medical and dental courses. Our dental cohort undertake a mid-year test (30xfree-response short answer to a question, SAQ) and end-of-year paper (4xSAQ,…

This study compares a scale, the Rosenberg Self-Esteem Scale, that was administered with four response categories to versions of the same scale that were administered with six and eight response categories. Respondents were randomly assigned to take one of the three versions of RSES. A rating scale utility analysis was conducted on all three…

This research aimed to develop a valid and reliable test to be used to detect sixth grade students' misconceptions and errors regarding the subject of fractions. A misconception diagnostic test has been developed that includes the concept of fractions, different representations of fractions, ordering and comparing fractions, equivalence of…

Secondary education students do not usually perceive history as a subject connected with their lives, backgrounds and interests. At the same time, prospective and in-service teachers do not always have a coherent vision of this discipline, which can reflect on their students' perceptions. This study makes use of a theoretical framework developed…

This article reports the results of an examination of the endorsement, reliability, and factorial validity of the VIA--Youth and assessment of character strengths and virtues developed for the general population in youth with and without intellectual disability. Findings suggest that, generally, youth with intellectual disability endorsed…

Increasing children's access to media has attached greater significance to media literacy education, the content and methods of which have changed with media development. This study aimed to investigate the effects of the Community of Inquiry (CoI) method on media literacy competencies in elementary students. To this end, 95 female sixth-grade…

This study compares the psychometric properties of reliability in Classical Test Theory (CTT), item information in Item Response Theory (IRT), and validation from the perspective of modern validity theory for the purpose of bringing attention to potential issues that might exist when testing organizations use both test theories in the same testing…

This research aims to reveal the effectiveness of the use of Kofie GeBoL media in improving (1) vector representation ability and (2) critical thinking ability in physics instruction. It is a descriptive quantitative study with the quasi-experiment design. It was conducted in two stages: empirical try out and implementation of Kofie GeboL to see…

The maximal reliability of a congeneric measure is achieved by weighting item scores to form the optimal linear combination as the total score; it is never lower than the composite reliability of the measure when measurement errors are uncorrelated. The statistical method that renders maximal reliability would also lead to maximal criterion…
