Causal analyses typically focus on average treatment effects. Yet for substantive research on topics like inequality, interest extends to treatments' distributional consequences. When individuals differ in their responses to treatment, three types of inequality may result. Treatment may shape inequalities between subgroups defined by pretreatment…

This article addresses the problem of testing the difference between two correlated agreement coefficients for statistical significance. A number of authors have proposed methods for testing the difference between two correlated kappa coefficients, which require either the use of resampling methods or the use of advanced statistical modeling…

Context: United States-educated athletic trainers (ATs) are expected to have more opportunities in the international environment as the number of mutual recognition agreements grows. However, no information is available from existing studies regarding the portability of current US athletic training education in an international environment.…

A number of studies have found multiple indicators multiple causes (MIMIC) models to be an effective tool in detecting uniform differential item functioning (DIF) for individual items and item bundles. A recently developed MIMIC-interaction model is capable of detecting both uniform and nonuniform DIF in the unidimensional item response theory…

This study explored factors associated with age of identification of autism spectrum disorder (ASD). Results of a one-way ANOVA indicated differences in age of diagnosis among the four regions in the United States, F(3, 650) = 7.618, p = 0.01. Tukey's post hoc comparisons of the groups indicated that the mean age of diagnosis in the Midwest (M =…

The purpose of this study was to compare business undergraduate online/hybrid course perceptions across three different preferred classroom learning environments (CLE): online, hybrid, or face-to-face (F2F). Six different perception-based outcomes were measured: easy to use technology, peer-perceived favorability of online/hybrid courses…

This study examined the difference between children with autism spectrum disorders (ASD) and children with typical development (TD) in mathematical word problem solving ability and the factors associated with these children's word problem-solving ability. A total of 20 children with ASD and 20 children with TD participated in this study.…

What causes the literacy gap and can schools compensate for it? The authors investigated 3 drivers of the gap: preliteracy knowledge, schooling, and the summer vacation. Longitudinal literacy data over 5 time points were collected on 126 five-year-olds attending higher or lower socioeconomic status (SES) schools during their first 15 months of…

Studies using tests scores as the dependent variable often report point estimates in student standard deviation units. We note that a standard deviation is not a standard unit of measurement since the distribution of test scores can vary across contexts. As such, researchers should be cautious when interpreting differences in the numerical size of…

In recent years, chess training is offered as a compulsory elective course in some pre-schools, whereas it is not offered in some other pre-schools. There are children who attend chess clubs outside of schools. Chess is considered to be a game of intelligence, and its effects on individuals have been the subject of many researches. This study was…

This study tested 2 related hypotheses. The first holds that high co-rumination anticipates heightened internalizing problems. The second holds that positive relationships with friends exacerbate the risk for internalizing problems arising from co-rumination. A sample of MZ twins followed from birth (194 girls and 170 boys) completed (a)…

The motivation, skills and professional identity of future teachers develop during their initial teacher education. The aim of this research is to assess the differences between first-year and fifth-year student teachers on a number of personality and motivational variables that are indicative of their approaches to learning, using a…

There are many reasons to believe that open-ended (OE) and multiple-choice (MC) items elicit different cognitive demands of students. However, empirical evidence that supports this view is lacking. In this study, we investigated the reactions of test takers to an interactive assessment with immediate feedback and answer-revision opportunities for…

This study is a substantive-methodological synergy in which exploratory structural equation modeling is applied to investigate the factor structure of multidimensional self-concept instruments. On the basis of a sample of German students (N = 1958) who completed the Self-Description Questionnaire I and the Self-Perception Profile for Children, the…

Introduction: Recent investigations have emphasized the need for university teachers to develop tutorial programs for students at university. Many universities are committed to broadening research on university teaching that will sharpen academic performance and levels of student satisfaction. Tutoring programs improve the development of the…
