Museums and science centers are constantly changing scientific environments which exert a lasting positive impact on the society through the popularization of science. One of the most effective strategies employed by these science popularization venues is the organization of scientific exhibitions using scientific devices which are presented to…

This case study applied the "weak theory" of Automatic Item Generation (AIG) to generate isomorphic item instances (i.e., unique but psychometrically equivalent items) for a large-scale assessment. Three representative instances were selected from each item template (i.e., model) and pilot-tested. In addition, a new analytical framework,…

With the increasing use of automated scores in operational testing settings comes the need to understand the ways in which they can yield biased and unfair results. In this paper, we provide a brief survey of some of the ways in which the predictive methods used in automated scoring can lead to biased, and thus unfair automated scores. After…

The use of the aggregate scoring method for scoring concordance tests requires the weighting of test items to be derived from the performance of a group of experts who take the test under the same conditions as the examinees. However, the average score of experts constituting the reference panel remains a critical issue in the use of these tests.…

Smartphones are a ubiquitous part of many people's lives, but little is known about their impact on everyday thought processes. Here we introduce the "spontaneous smartphone checking scale" (SSCS)--which measures the tendency to direct attention toward one's smartphone, unpreceded by external prompts (e.g., notifications, or alerts) and…

This article is concerned with a subset of numerically stable and scalable algorithms useful to support computationally complex psychometric models in the era of machine learning and massive data. The subset selected here is a core set of numerical methods that should be familiar to computational psychometricians and considers whitening transforms…

In 1998, Plucker and Runco provided an overview of creativity assessment, noting current issues (fluency confounds, generality vs. specificity), recent advances (predictive validity, implicit theories), and promising future directions (moving beyond divergent thinking measures, reliance on batteries of assessments, translation into practice). In…

Though a substantial amount of research exists on imputing missing scores in educational assessments, there is little research on cases where responses or scores to an item are missing for all test takers. In this paper, we tackled the problem of imputing missing scores for tests for which the responses to an item are missing for all test takers.…

Background: The goal of this systematic review was to provide an overview of self-report measures of stress in populations on the autism spectrum. In addition, information regarding psychometric properties was discussed as well. Methods: Four databases were systematically searched following the PRISMA guidelines and using strict eligibility…

This study uses a rigorous research process to explore the psychometric properties of the Gifted Rating Scale-School Form (GRS-S) within the Qatari educational context. We employed stratified cluster sampling of 326 students (aged 6-13 years, M = 10.9) from 25 public schools in Doha. Data was collected in the second semester of the 2023-2024…

Technological mediation has gained relevance in teaching mathematics. Its usefulness and impact depend, to a great extent, on how students approach the learning of the discipline. Two independent instrumental studies were conducted to analyze the psychometric properties of the Spanish version of the Mathematics and Technology Attitudes Scale…

With the increasing interest in Positive Psychology within the realm of L2 learning, the role of positive emotions, particularly Foreign Language Enjoyment (FLE) has garnered attention in Second Language Acquisition research (Dewaele & MacIntyre, 2014). Despite the growing interest in FLE in Turkey, the widely used Foreign Language Enjoyment…

Researchers who work with ordinal rating scales sometimes encounter situations where the scale categories do not function in the intended or expected way. For example, participants' use of scale categories may result in an empirical difficulty ordering for the categories that does not match what was intended. Likewise, the level of distinction…

Objective: Cyberbullying, which is defined as an intentional, aggressive, and repetitive behaviour where a person or group uses electronic devices (primarily the Internet and smartphones), is a new concept specifically for the Iranian educational system. We examined the Bullying and Cyberbullying Scale for Adolescents' (BCS-A) psychometric…

Measures of academic engagement and disruptive behavior in students are strong predictors of social, academic, and lifelong career outcomes. Educators need a measurement tool that is feasible, accurate, and cost-effective in order to identify students who may be in need of additional behavioral support. Direct Behavior Ratings (DBRs) offer a…
