The purpose of this study was to determine whether there were differences in satisfaction levels for students, based on enrollment status groups within a hybrid course and to examine the relationship between student satisfaction and student-instructor interaction within a hybrid course and. This was addressed through a quantitative correlational…

Math underachievement is of grave concern with 42% of 4th grade and 36% of 8th grade students achieving at a proficient or advanced level in mathematics, and schools are continually searching for interventions to implement with struggling students. The problem addressed in this study is recently an elementary school purchased access to…

Pseudowords (words that are not real but resemble real words in a language) have been used increasingly as a technique to reduce contamination due to construct-irrelevant variance in assessments of verbal fluid reasoning (Gf). However, despite pseudowords being researched heavily in other psychology sub-disciplines, they have received little…

The growing trend of adult learners in Christian universities offers an opportunity to enrich their marriages and spiritual formation. A marriage enrichment seminar was presented to sixteen adult and graduate students enrolled in the Adult Graduate Studies program at Evangel University, and their spouses, in a two-day, eight-hour relationship…

The purpose of this study was to investigate the incremental validity of a set of domain general cognitive measures added to a traditional screening battery of early numeracy measures. The sample consisted of 458 kindergarten students of whom 285 were designated as severely at-risk for mathematics difficulty. Hierarchical multiple regression…

Determining the professional competencies of a degree is an arduous task that sometimes does not respond to the reality of what society expects for such studies. This article attempts to determine what competencies students in the field of Educational Psychology, which were determined by them. This study was conducted in three different…

This article explores the "art bias"--the pervasive association between creativity and art in implicit theories of creativity. It also attempts to connect creativity research in this area with literature on the theory of social representations. The data comes from an online survey completed by 195 participants mainly from the United…

The authors of the focus article in this issue have emphasized the continuing confusion among some researchers regarding various indicators used in structural equation models (SEMs). Their major claim is that causal indicators are not inherently unstable, and even if they are unstable they are at least not more unstable than other types of…

Growing a national certification program requires systematic research to determine its impact on certificate holders and effectiveness in serving the public. Launched in 2007, the literature to date on the efficacy and value-added effect of the Nationally Certified Educational Diagnostician (NCED) credential is virtually nonexistent. Increased…

Correlation attenuation due to measurement error and a corresponding correction, the deattenuated correlation, have been known for over a century. Nevertheless, the deattenuated correlation remains underutilized. A few studies in recent years have investigated factors affecting the deattenuated correlation, and a couple of them provide alternative…

The simultaneous item bias test (SIBTEST) method regression procedure and the differential item functioning (DIF)-free-then-DIF strategy are applied to the logistic regression (LR) method simultaneously in this study. These procedures are used to adjust the effects of matching true score on observed score and to better control the Type I error…

Purpose: To quantitatively examine the effects of body position on the positioning of the epiglottis, tongue, and velum at rest and during speech. Method: Videofluoroscopic data were obtained from 12 healthy adults in the supine and upright positions at rest and during speech while the participants produced 12 VCV sequences. The effects of body…

Objectives: To demonstrate how the bootstrap method could be conducted in exploratory factor analysis (EFA) with a syntax written in SPSS. Methods: The data obtained from the Texas Childhood Obesity Prevention Policy Evaluation project (T-COPPE project) were used for illustration. A 5-step procedure to conduct bootstrap factor analysis (BFA) was…

Compression, estimation, and prediction are basic problems in Information theory, statistics and machine learning. These problems have been extensively studied in all these fields, though the primary focus in a large portion of the work has been on understanding and solving the problems in the asymptotic regime, "i.e." the alphabet size…

Fully updated to reflect the most recent changes in the field, the Second Edition of "Propensity Score Analysis" provides an accessible, systematic review of the origins, history, and statistical foundations of propensity score analysis, illustrating how it can be used for solving evaluation and causal-inference problems. With a strong…
