Multiple regression is a family of statistics used to investigate the relationship between a set of predictors and a criterion (dependent) variable. This procedure is applicable in a variety of research contexts and data structures. Consequently, and similar to quantitative traditions in sister-disciplines such as education and psychology (see…

This study examined the use of dexterity as an indicator of future performance of beginning welders. This could lead to the selection or recruitment of participants for welding training programs. With a high demand for welders, it is imperative that welding training programs be efficient at producing certified welders. The time required to train…

Predictive validity considerations in selection dictate choice of the predictor with the highest predictive validity. Implementation of this principle in any specific selection process inevitably entails choice between imperfectly correlated alternative predictors, real or hypothetical, which are equivalent in terms of predictive validity. We show…

Lipreaders recognize words with phonetically impoverished stimuli, an ability that varies widely in normal-hearing adults. Lipreading accuracy for sentence stimuli was modeled with data from 339 normal-hearing adults. Models used measures of phonemic perceptual errors, insertion of text that was not in the stimulus, gender, and auditory speech…

A strong, positive science, technology, engineering, and mathematics (STEM) identity is a predictor of future career choice in a STEM field. In this commentary, major concepts are explored within and among four different research studies with implications regarding STEM or science identity. This commentary describes ways in which one can view STEM…

As research on mediation has grown, so too has interest in identifying ways to assess the size of indirect effects in a mediation analysis. One such estimate -- the ratio of the indirect effect to the total effect (P[subscript M]) -- was tested in a sample of 21,297 children from the Early Childhood Developmental Study. Results showed that the two…

This study examined the degree to which individual differences in students' (N = 232) concepts of size and scale are explained by factors such as students' innate sense of number, out-of-school science experiences, exposure to size and scale instruction, gender identities, and racial/ethnic identities. There is increasing emphasis being placed on…

The literature exploring the executive function correlates of bilingualism is vast, but to date, few studies have concentrated on children, for whom the bilingual advantage appears even more inconsistent than for adults. We investigate a highly heterogeneous group of children (in terms of bilingual experience and socioeconomic status) and identify…

Scope and Method of Study: The purpose of this study was to explore the relationships between the expression of critical thinking and motivational orientation (i.e. autonomy, controlled and impersonal) and the relationship between expressed critical thinking and self-theories of intelligence mindsets (i.e. entity vs. incremental). Correlation and…

Ensuring student success has been a ubiquitous and enduring goal of institutions of higher education, making it paramount to identify how this goal can be achieved. The researchers identified social integration, perceived institutional commitment to student success, and academic preparedness as potential predictors of student academic success. An…

Purpose: Research on developmental language disorder (DLD) in adulthood has increased rapidly in recent years. However, to date, there has been no systematic literature review on this topic, thereby limiting the possibility to have a comprehensive overview of publications in this field. Method: Following Preferred Reporting Items for Systematic…

The Chinese Radical Assembly Game (CRAG) is an online platform that assesses the lexical competence. In which, individuals select different Chinese radicals to combine them and form a legitimate character. This concept is similar to that of creative synthesis. Therefore, this study aimed to examine whether the CRAG response process involves…

Teachers who interact directly with people were evaluated one of risk groups of burnout syndrome. The aim of this research was to determine work-related behaviors and experience patterns of physical education teachers and to analyze them according to the individually burnout factors. A total of 179 physical education teachers, 98 (54.7%) males and…

Facebook is the most popular social network site (SNS) globally, and WeChat is the top SNS in China, so few regions in the world exist where both SNSs are used simultaneously and are popular among the younger generation, and even fewer studies have been conducted on the comparison of the use of the two top SNSs. This study aims to fill this gap by…

In classrooms, some transitions between activities impose (quasi-)synchronicity, meaning there is a need for learners to move between activities at the same time. To make real-time decisions about when to move to the next activity, teachers need to be able to balance the progress of their students as they work at different paces. In this paper, we…
