A slowdown or a speedup in response times across experimental conditions can be taken as evidence of online deployment of knowledge. However, response-time difference measures are rarely evaluated on their reliability, and there is no standard practice to estimate it. In this article, we used three open data sets to explore an approach to…

In this paper, we explore measurements of design creativity through metrics related to the processes used in designing and relate them to the metrics used in psychology for idea creativity, ie, novelty and fluency. Our goal was to test the reliability of psychometric measures of creativity to assess creativity in team design. We studied 19 teams…

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…

Different definitions and tests of dyslexia can cause unfairness and make life difficult for people with dyslexia as well as for the professionals. In 2012, the Danish government decided to support the fight against dyslexia. The government issued a public tender for the development of "a standardized, electronically administered test of…

Ferrari (2010) stated 20-25% of people self-identified as chronic procrastinators, which is a common self-regulatory failure involving stalling the initiation or completion of important duties or responsibilities until the last minute, after a predetermined deadline, or indefinitely (Dryden, 2000). This study is the first attempt to translate and…

The current study examined the reliability of The Reading League Curriculum-Evaluation Guidelines (CEGs), which were developed to help school-based teams rate the presence of red flags when considering adopting specific literacy curricula. Coders (n = 30) independently used the CEGs to evaluate a free online English language arts curriculum. The…

Although equality of opportunity in education is a current and important issue, most of the studies on this subject are based on theoretical studies rather than empirical studies. The main reason for this can be said to be the lack of a valid and reliable measurement tool in this field. For this reason, this study aims to develop a valid and…

This study explores the use of artificial intelligence in grading high-stakes physics exams, emphasizing the application of psychometric methods, particularly item response theory, to evaluate the reliability of AI-assisted grading. We examine how grading rubrics can be iteratively refined and how threshold parameters can determine when…

This was the first study in which a psychometrically validated STEM measure, the "Student STEM" (S-STEM), was studied for HSSWD. This study also represented the first time a psychometrically validated STEM measure, the "Student STEM" (S-STEM), was studied for HSSWD. Data were collected from 229 HSSWD in a western state and…

Creativity is highly valued in both education and the workforce, but assessing and developing creativity can be difficult without psychometrically robust and affordable tools. The open-ended nature of creativity assessments has made them difficult to score, expensive, often imprecise, and therefore impractical for school- or district-wide use. To…

This study examined the validity of the Greek version of the Societal Attitudes Towards Autism (SATA) scale in a Greek community sample (n = 633) and explored how the demographic variables of the sample modulate knowledge and attitudes regarding people with Autism Spectrum Disorder (ASD). The principal component analysis confirmed the…

Background: Adults with intellectual disabilities should participate in the diagnostics of their mental health. The Glasgow Depression Scale for people with a Learning Disability (GDS-LD) and its Carer Supplement (GDS-CS) were translated into German and tested. Methods: Internal consistency, criterion validity and inter-test reliability were…

Objective: We aimed to examine the psychometric properties of the Scale of Perfectionism and Excellencism (SCOPE) in a novel sample, Australian adolescents. Method: The cross-sectional sample consisted of 350 participants (79 male, 271 female; mean age 17.9 years, age range = 15-20 years) from a secondary 10 school and university who completed a…

This study tested the psychometric properties of the "Sense of Belonging in STEM" Scale (SOB-STEM), a new scale measuring students' subjective evaluation of their academic and social experiences in STEM learning contexts, primarily focusing on purposeful interpersonal interactions. Data from 758 college students were analyzed, yielding…

Metacognition awareness is a fundamental skill for the 21st century. Accurately measuring metacognitive awareness would be highly relevant regardless of age, background, or cognitive abilities. The current study aimed to evaluate the psychometric properties of the 19-item Metacognitive Awareness Inventory-Arabic version (MAI-A) in the general…
