Previous research explicates ordinal and disordinal interactions through the concept of the "crossover point." This point is determined via simple regression models of a focal predictor at specific moderator values and signifies the intersection of these models. An interaction effect is labeled as disordinal (or ordinal) when the…

Educational materials focused on spatial data analysis often feature mathematical descriptions of methods and step-by-step instructions of software tools, but infrequently discuss the set of decisions involved in specifying a statistical model. Failing to consider model specification may lead to specification searching, or the process of repeating…

This study used binary logistic regression to predict social trust with five demographic variables from a national sample of adult individuals who participated in The General Social Survey (GSS) in 2012. The five predictor variables were respondents' highest degree earned, race, sex, general happiness and the importance of personally assisting…

At a time when the national conversation is focused on lagging upward mobility, it is no surprise that many educators point to poverty as the explanation for mediocre test scores among U.S. students compared to those of students in other countries. If American teachers in struggling U.S. schools taught in Finland, says Finnish educator Pasi…

In this paper we argue that simply identifying gateway courses in which a large number of students fail or withdraw and focusing attention on them may not always be the best use of limited resources. No matter what we do, there will always be courses with high D/F/W rates simply because of the nature of their content and the preparation of the…

Rather than assessing its causal effect on educational attainment, the authors of this article aim to use the concept of cultural capital to define a huge, complex and interconnected collection of educational and school strategies adopted by students and families and to examine the way that these strategies are related to school inequalities. Data…

Data from nine introductory microeconomics classes was used to test the effect of student learning style on academic performance. The Kolb Learning Style Inventory was used to assess individual student learning styles. The results indicate that student learning style has no significant effect on performance, undermining the claims of those who…

Directional dependency is a method to determine the likely causal direction of effect between two variables. This article aims to critique and improve upon the use of directional dependency as a technique to infer causal associations. We comment on several issues raised by von Eye and DeShon (2012), including: encouraging the use of the signs of…

In recent decades, a dramatic shift occurred in higher education throughout the world. Women now enroll in and complete more education than men in the majority of countries. Using a lagged cross-sectional design on a dataset of 75 countries from 1990 to 2008, this study examines the predictors of the current gender gap in tertiary enrollment. I…

This study examines the within-field persistence rates of physical science/engineering (PS/E) students compared with those of students in life science, business, social science, education, and humanities. The data are drawn from a nationally representative sample of college matriculates and include students' high school and college transcript…

This study examined dysfunctional career thoughts and attitudes as predictors of vocational identity among high school students with Attention Deficit Hyperactivity Disorder (ADHD). Regression analysis results indicated that dysfunctional career thoughts and attitudes were significant predictors of vocational identity, accounting for 42% of the…

The focus of this paper is assessing the impact of measurement errors on the prediction error of an observed-score regression. Measures are presented and described for decomposing the linear regression's prediction error variance into parts attributable to the true score variance and the error variances of the dependent variable and the predictor…

The authors examined how six factors related to content and interaction affect students' perceptions of learning, satisfaction, and quality in online master of business administration (MBA) courses. They developed three scale items to measure each factor. Using survey data from MBA students at a private university, the authors estimated structural…

Working with students who are deaf or hard of hearing (DHH) can raise questions about whether language and literacy delays and difficulties are related directly to late and limited access to spoken language, to co-occurring language learning disabilities (LLD), or to both. A new Test of Integrated Language and Literacy Skills, which incorporates…

This paper reports findings from a multi-year study of the scale-up of Reading Apprenticeship (RA), an approach to improve academic literacy by helping teachers provide the support students need to be successful readers in the content areas. WestEd's Strategic Literacy Initiative (SLI), began developing the program in 1995 and has since reached…
