Traditional psychometric guidelines suggest that at least several hundred respondents are needed to obtain accurate parameter estimates under the Rasch model. However, recent research indicates that Rasch equating results in accurate parameter estimates with sample sizes as small as 25. Item parameter drift under the Rasch model has been…

Effective classroom management is critical for student and teacher success. Because teachers receive limited preservice preparation and in-service support in classroom management, educational leaders (e.g., school psychologists, behavior coaches, mentor teachers, and administrators) need efficient and effective tools to identify teachers'…

In randomized experiments, inventories with reverse-keyed items are compared with inventories in which all the items are either positively or negatively associated with the underlying concept. The results show that with reverse keying, a control of the potential bias was not sufficient; likewise, the factorial structure, reliability, and validity…

Prior work has documented a substantial penalty associated with taking the Partnership for Assessment of Readiness for College and Careers (PARCC) online relative to on paper (Backes & Cowan, 2019). However, this penalty does not necessarily make online tests less useful. For example, it could be the case that computer literacy skills are…

Digital literacy is essential for scientific literacy in a digital world. Although the NGSS Practices include many activities that require digital literacy, most studies have examined digital literacy from a generic perspective rather than a curricular context. This study aimed to develop a self-report tool to measure elements of digital literacy…

With the research reported here, we specifically aim to develop application products of scientific work independence instruments through science integrated learning (SIL) for various education levels (elementary schools, junior high schools, senior high schools, and universities). The SIL model was applied in learning to determine specific…

Background: As educational institutions increasingly operate as multicultural hubs, leaders must navigate the complexities of cultural differences, language barriers and diverse learning styles in digital environments. These challenges are amplified by the lack of non-verbal cues and the asynchronous nature of online communication, which can lead…

The aim of this study was twofold: (a) to assess the psychometric properties of the Revised Early Adolescent Temperament Questionnaire (EATQ-R) and the Revised Adult Temperament Questionnaire (ATQ-R) among 685 Finnish early adolescents and their parents and (b) to investigate the extent to which adolescents and their parents share similar…

Initial studies have presented the "Music-based Scale for Autism Diagnostics" (MUSAD) as a promising DSM-5-based observational tool to identify autism spectrum disorder (ASD) in adults with intellectual disability (ID). The current study is the first to address its clinical utility in a new sample of 124 adults with ID (60.5% diagnosed…

The Social Support for Exercise Subscales are commonly used among Hispanic populations. The aims of this study were to test the validity and reliability of the Spanish-language version of the Social Support for Exercise Subscales and test the invariance of the Spanish- and English-language versions. Data were from a subsample of Hispanic adults in…

Despite the dramatic rise in Autism Spectrum Disorder (ASD) prevalence, limited information is known about ASD knowledge of the general population. The Autism Spectrum Knowledge Scale, General Population version (ASKSG) was collaboratively constructed to create a measure of ASD knowledge specifically for the general population. The ASKSG is a…

Assessment of individuals on the autism spectrum often includes a measure of nonverbal IQ. One such measure is the Raven's Standard Progressive Matrices (RSPM). For large research studies with participants distributed nationally it is desirable for assessments to be available online. Because time is a premium, it is ideal that the measure produces…

The purpose of the present study was to develop an observational coding system that examines coaches' leadership behaviours in sport. Drawing from an integration of the dimensions emphasized within the full-range leadership model, and particularly, transformational leadership (TFL), the Coach Leadership Assessment System (CLAS) was designed to…

Numerous researchers have proposed methods for evaluating the quality of rater-mediated assessments using nonparametric methods (e.g., kappa coefficients) and parametric methods (e.g., the many-facet Rasch model). Generally speaking, popular nonparametric methods for evaluating rating quality are not based on a particular measurement theory. On…

Due to early onset and rising prevalence rates, there is an established need for early identification of youth demonstrating symptoms of internalizing disorders (e.g., anxiety and depression). Accordingly, calls have been made for the use of universal screening tools to identify internalizing behavior risk. Current research has spoken to the…
