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…

The authors describe how Middle Eastern Muslims are represented in a text set of award-winning picture books. Most were written by authors with outsider perspectives who wrote about (a) antiquated times and practices and (b) war-stricken countries and dangerous journeys. Although most of the books are not problematic on their own, the large number…

The majority of task repetition studies have focused on learners' oral production, but whether task repetition can promote learning in other skill areas such as writing remains to be seen. The current study compared the effect of procedural and content repetition on French learners' accurate production of the passé composé during collaborative…

In dichotomous item response theory (IRT) framework, the asymptotic standard error (ASE) is the most common statistic to evaluate the precision of various ability estimators. Easy-to-use ASE formulas are readily available; however, the accuracy of some of these formulas was recently questioned and new ASE formulas were derived from a general…

Elementary students who demonstrate accuracy and speed in handwriting are better equipped to generate higher quality, longer composition. Unfortunately, students with autism spectrum disorder (ASD) tend to encounter significant difficulties with legibility, size, and speed of handwriting. The present study used a single-subject, multiple-baseline…

Immediacy is one of the necessary criteria to show strong evidence of treatment effect in single case experimental designs (SCEDs). With the exception of Natesan and Hedges (2017) no inferential statistical tool has been used to demonstrate or quantify it until now. We investigate and quantify immediacy by treating the change-points between the…

The purpose of this study was to investigate song teaching approaches and their effect on the singing accuracy of third grade elementary students using an original song with no repeated phrases. Students (N = 318) and teachers (N = 22) were from a large school district in the Western United States with a diverse demographic population. Three song…

The effects of learning to sing with and without Curwen hand signs on singing accuracy in kindergarten-age children were compared. Participants comprised an experimental group (Curwen signs) and a control group (without signs), each containing 33 children aged 5 to 6 years. All participants took 30 music lessons centered on learning songs. The…

Active interviewing approaches can exploit the verbal differences between truthtellers and liars, thus improving detecting deception. One such method is the Reality Interview (RI) aimed to facilitate recall from truthtellers, while increasing the difficulty for liars. This study investigated whether the RI could improve the diagnostic accuracy of…

Research shows that alcohol has a small and inconsistent effect on eyewitness recall and no effect on witnesses' lineup decisions. Much of this literature has tested participants with low-to-moderate blood alcohol concentration (BAC) levels, and no study has directly examined how identification procedure impacts intoxicated witnesses' decisions.…

Developing tools to support students and learning in a traditional or online setting is a significant task in today's educational environment. The initial steps toward enabling such technologies using machine learning techniques focused on predicting the student's performance in terms of the achieved grades. However, these approaches do not…

Executive function (EF) decline is a consistent early sign of Alzheimer's disease (AD) among adults with Down syndrome (DS), which means that baseline measures of EF for individuals with DS are vital to allow detection of meaningful decline. We developed a framework to extract measures of three core components of EF (memory updating, inhibitory,…

Purpose: The use of sign-supported speech (SSS) in the education of deaf students has been recently discussed in relation to its usefulness with deaf children using cochlear implants. To clarify the benefits of SSS for comprehension, 2 eye-tracking experiments aimed to detect the extent to which signs are actively processed in this mode of…

Background and Aims: In educational measurement, performance assessments occupy a niche for offering a true-to-life format that affords the measurement of high-level cognitive competencies and the evidence to draw inferences about intellectual capital. However, true-to-life formats also introduce myriad complexities and can skew if not outright…

Purpose: Earlier investigations based on word and sentence repetition tasks had revealed that the most prevalent metrical pattern in German (the trochee)--unlike the iambic pattern--facilitates articulation in patients with apraxia of speech (AOS; e.g., Aichert, Späth, & Ziegler, 2016), confirming that segmental and prosodic aspects of speech…
