Factor analysis is a versatile class of psychometric techniques used by researchers to provide insight into the psychological dimensions (factors) that may account for the relationships among variables in a given dataset. The primary goal of a factor analysis is to determine a more parsimonious set of variables (i.e., fewer than the number of…

Purpose: Across the treatment literature, behavioral speech modifications have produced variable intelligibility changes in speakers with dysarthria. This study is the first of two articles exploring whether measurements of baseline speech features can predict speakers' responses to these modifications. Method: Fifty speakers (7 older individuals…

Relatively little is known regarding factors associated with the choice of a research career among practicing physicians, and most investigations of this issue have been conducted in the absence of a theoretical/conceptual model. Therefore we designed a survey to identify the determinants of decisions to pursue a biomedical research career based…

We discuss strategies for the general solution of single-step 1D constant acceleration problems. In a slightly restricted form, these problems have five variables (?"x," "v[subscript 0]," "v," "a" and "t") and two independent equations, so three variables must be given to solve for the other two,…

This quantitative study examined the gender-based difference toward the adoption of online learning based on constructs of the Theory of Planned Behavior (TPB). It is also aimed to predict the Behavioral Intention of the adoption of online learning based on the predicting variables of the TPB, Attitude, Subjective Norm, and Perceived Behavioral…

Professional learning of teachers and instruction have paramount importance if improved student performance is desired. Despite their recognized importance, there is a clear paucity of research on the field of professional development (PD) and instruction. Moreover, the association between professional development and instruction has not been well…

The purpose of the study was to examine graduate student ratings of instruction in order to understand why online ratings are lower than face-to-face ratings. More than 5,000 graduate students rated their instruction in the areas of instructional methods, faculty/student interactions, and assessment of student learning. Results indicated that…

This article investigates the critical influence principals have on mitigating or exacerbating teacher turnover. Both South Carolina Department of Education (SCDE) data and National Center of Education Statistics (NCES) Common Core of Data (CCD) from Academic Years 2016 to 2020 were used to analyze the research question. A Restricted Maximum…

Drawing on Geary's (1995) evolution-based model of cognitive and academic development, this study investigated the relation between biologically primary skills (vocabulary, executive functions, and visual-spatial processing) and subsequent word reading and calculation. It also examined the extent to which these relations were mediated by…

Tertiary institutions are experiencing an increased number of enrolments, with students varying in their demographics, previous education, and academic achievement. This relative increase in undergraduate enrolments in Australia has not translated to an increase in student retention or graduate numbers. This prompts the need to explore predictors…

Immigrant and refugee children and adolescents form a growing socially, culturally, and economically diverse group with the potential for wide-ranging adaptation outcomes. The goal of the study was to examine whether developmental competencies (social-emotional and academic) and sociodemographic disparities (e.g., SES and migration class)…

Early research on the COVID-19 pandemic has demonstrated differential impact on the Latinx community. There has been limited research exploring the mental health outcomes of the pandemic on Latinx youth. This study explores the severity of pandemic-related stress on Latinx youth considering their resilience factors and previous adverse childhood…

The purpose of this study was to explore how returning to teaching during the Coronavirus disease (COVID-19) pandemic impacted teachers' stress and anxiety. Specifically, the study investigated how teachers' anxiety changed during the first month of school. Additionally, the study explored the association of teachers' stress and anxiety and…

Research Findings: This study examined performance on self-regulatory tasks, in addition to individual characteristics including cognitive ability, receptive and expressive language skills, planning, and behaviour as contributing factors to early learning difficulties. Twenty-nine children born with ELBW and 30 comparison children at four years of…

For many countries, inequitable access to rigorous content and instruction at the early grades leads to the low academic performance for students with fewer resources at home. One way to assess these inequities, and identify possible mediators, is to consider the role of instructional leadership as a means for schools to set educational goals for…
