Sensitivity analyses can inform evidence-based education policy by quantifying the hypothetical conditions necessary to change an inference. Perhaps the most prevalent index used for sensitivity analyses is Oster's (2019) Coefficient of Proportionality (COP). Oster's COP leverages changes in estimated effects and R[superscript 2] when observed…

The relationship between confidence and accuracy has long been an important and controversial topic within the field of human memory. In a recent review article, Schwartz (2024). "Inferential theories of retrospective confidence." Metacognition & Learning.) competently summarized some of the key empirical findings on this issue and…

When individuals are released from prison, they typically enter a period of post confinement community supervision. While under community supervision, their behaviors are subject to special conditions requiring them to report to supervisors and prohibiting certain behaviors such as drug and alcohol use. Many supervisees are returned to prison…

In Savalei's (2011) simulation that evaluated the performance of polychoric correlation estimates in small samples, two methods for treating zero-frequency cells, adding 0.5 (ADD) and doing nothing (NONE), were compared. Savalei tentatively suggested using ADD for binary data and NONE for data with three or more categories. Yet, Savalei's…

Pre-lab summary videos supplement gross anatomy courses by helping students navigate difficult concepts, increasing student confidence, and allowing for content review outside the laboratory. Few studies have examined the direct correlation between video viewing and performance outcomes. This study uses performance outcome data from six…

The objective of this study is to examine social media mindfulness and other social media habits as predictors of depression in adolescents. As depression and poor mental health increase for American adolescents, so does the research surrounding the positive outcomes associated with mindfulness. It is possible that mindfulness could be an…

Purpose: There is a growing body of research on developmental language disorder (DLD), but very few studies have focused on the role of cognitive abilities in adulthood. The present study explored the relationship between cognition and language in adults with and without DLD. Method: Sixty participants, 30 language typical (LT) adults and 30 with…

We show that learners generalized more broadly around the learned stimulus when they expected more variability between the learning set and the generalization set, as well as within the generalization set. Experiments 1 and 3 used a predictive learning task and demonstrated border perceptual generalization both when expected variability was…

Deterioration of students' mathematics achievement has been a common problem while their mathematics perception and self-efficacy have been reported to determine their achievement. However, little is known about the potential relationships among them. Therefore, this study attempted to investigate the extent of influence of students' mathematics…

Oblique bifactor models, where group factors are allowed to correlate with one another, are commonly used. However, the lack of research on the statistical properties of oblique bifactor models renders the statistical validity of empirical findings questionable. Therefore, the present study took the first step to examine the statistical properties…

Purpose of the research is to examine the predictive effect of self-compassion levels of preschool period children's mothers over children's loneliness levels. The research was conducted with 196 children, between the ages of 60-72 months and who are attending preschool education in a metropolis in the South-eastern Anatolia Region, and their…

Research Findings: This study examined the association between preschool children's social-emotional competence (SEC), defined by their social skills and problem behaviors, and numeracy skills. It also examined if any subdomains of SEC predicted preschool numeracy above and beyond latent social skills or problem behaviors variables. Data came from…

Universities must confront social challenges and prepare their students to be future socially responsible professionals. This research considers social responsibility in depth and examines how it can be promoted among university students. Specifically, it analyses whether prosocial behaviour and moral values are predictor variables, and to study…

The influence of andragogical principles on employee motivation to transfer training was examined in this study. The research problem is whether the principles of andragogy (Need to Know, Self-Concept, Experience, Readiness to Learn, Orientation to Learning, and Motivation to Learn) predict motivation to transfer training among individuals who…

Many applications of structural equation modeling involve ordinal (e.g., Likert) variables. A popular way of dealing with ordinal variables is to estimate the model with polychoric correlations rather than Pearson correlations. Such an estimation also requires the asymptotic covariance matrix of polychoric correlations. It is computationally…
