This article replies to the responses to my article on "Sex and the Census: Why surveys should not conflate sex and gender identity". Fugard conflates sex itself with the characteristics associated with sex, such as finger length ratios, leading to the erroneous implication that binary sex is not a useful explanatory variable. Hines…

The purpose of this study was to examine the use of a misspecified calibration model and its impact on proficiency classification. Monte Carlo simulation methods were employed to compare competing models when the true structure of the data is known (i.e., testlet conditions). The conditions used in the design (e.g., number of items, testlet to…

We examined the relationship between interval identification skill and error detection skill in preservice teachers, accounting for timbral differences by including piano and vocal stimuli. The interval identification test was comprised of 33 items spanning from C2 to B5. Fifteen error detection items were monophonic melodies, two measures long,…

To live independently, it is critical that students with disabilities maintain the basic mathematical skills they have acquired so they may apply these skills in daily life. To support maintenance of mathematical skills among students with developmental disabilities, the researchers used a multiple probe across participants design to examine the…

Institutional staff such as enrollment managers, business officers, and institutional researchers are often asked to predict enrollments. Developing any predictive model can be intimidating, particularly when there is no textbook to follow. This paper provides a practical framework for generating enrollment projection options and for evaluating…

Whereas extensive studies have examined the effectiveness of inquiry-based learning in chemistry education, few have tracked undergraduate performance throughout the college chemistry curricula. In this study, we describe an instructional model of conceptual learning and inquiry-based practices (CLIP) and assess students' transformation of…

Children with dyslexia face persistent difficulties in acquiring reading skills, often making guessing errors characterized by the replacement of a word by an orthographic neighbour. These reading errors could be related to inhibition problems within the reading task. Previous studies examining inhibition skills in dyslexic children led to unclear…

This study provides an example of using single case experimental design to guide data-driven, low-inference interventions for an individual using customized displays on a speech-generating device and can serve as an example for interventionists who need to compare intervention strategies to identify approaches that are most appropriate for a…

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…
