It is imperative to collect validity evidence prior to interpreting and using test scores. During the process of collecting validity evidence, test developers should consider whether test scores are contaminated by sources of extraneous information. This is referred to as construct irrelevant variance, or the "degree to which test scores are…

The demand for science, technology, engineering, and mathematics (STEM) courses in education aligns with the need to advance society through innovation and research. Proficiency in STEM courses and curriculum is critical for nations to become global economic leaders. However, the majority of students in high school do not participate in STEM…

This sequential explanatory mixed method study addressed the effect of technology-facilitated Language Experience Approach on students' language arts scores and reading attitudes of standard I students in Belize City. There were three intervention and three control schools that participated in the study. The study's first phase was a 10-week…

Does relaxing strict school discipline improve student achievement, or lead to classroom disorder? We study a 2012 reform in New York City public middle schools that eliminated suspensions for non-violent, disorderly behavior, replacing them with less disruptive interventions. Using a difference-in-differences framework, we exploit the sharp…

School autonomy has been and continues to be one of the most important education reform strategies around the world despite ambiguity about its theoretical and empirical effects on students learning. We use international data from PISA to test three country-level factors that might account for inconsistent results in prior literature: (1) the…

Job automation is a topical issue in a technology-driven labor market. However, greater amounts of human capital (e.g., often measured by education, and information-processing skills, including adult literacy) are linked with job security. A knowledgeable and skilled labor force better resists unemployment and/or rebounds from job disruption…

This study differentially examined the relation between two clinical constructs: "social anxiety" and "social competence" in autism spectrum disorder (ASD). Employing two questionnaires (SASKO; IU), individuals with ASD (n = 23) showed increased scores of SOCIAL ANXIETY (SASKO) and of INTOLERANCE OF UNCERTAINTY (IU), compared…

Cadaveric dissection offers an important opportunity for students to develop their ideas about death and dying. However, it remains largely unknown how this experience impacts medical students' fear of death. The current study aimed to address this gap by describing how fear of death changed during a medical gross anatomy dissection course and how…

Estimation of parameters for the many-facets Rasch model requires that conditional on the values of the facets, such as person ability, item difficulty, and rater severity, the observed responses within each facet are independent. This requirement has often been discussed for the Rasch models and 2PL and 3PL models, but it becomes more complex…

This paper uses a newly discovered data set on examination results by gender from 1913 to 1986 to show that the gender gap in examinations at the University of Oxford has existed for over a century. We show that after declining for almost 70 years the gender gap in Firsts increased significantly after the introduction of coresidence -- the…

Decision consistency (DC) is the reliability of a classification decision based on a test score. In professional credentialing, the decision is often a high-stakes pass/fail decision. The current methods for estimating DC are computationally complex. The purpose of this research is to provide a computationally and conceptually simple method for…

The present study attempted to to investigate factors which affect EFL writing scores through using generalizability theory (G-theory). To this purpose, one hundred and twenty students participated in one independent and one integrated writing tasks. Proceeding, their performances were scored by six raters: one self-rating, three peers,-rating and…

The estimation of test score "gaps" and gap trends plays an important role in monitoring educational inequality. Researchers decompose gaps and gap changes into within- and between-school portions to generate evidence on the role schools play in shaping these inequalities. However, existing decomposition methods assume an equal-interval…

Developmental studies examining relations between word reading (WR) and decoding in typical and dyslexic populations routinely cut the reading distribution to form distinct groups. However, dichotomizing continuous variables to study development is problematic for multiple reasons. Instead, we modeled and visualized the parallel growth of WR and…

This secondary analysis examined the impact of respondent-level factors on scores on the Supports Intensity Scale-Adult Version (SIS-A) to determine if there were patterns of differences in SIS-A scores based on the number of respondents and the pairings of respondents that were included in SIS-A interviews. Results indicated that having fewer…
