Complex surveys are often used to estimate causal effects regarding the effects of interventions or exposures of interest. Propensity scores (Rosenbaum & Rubin, 1983) have emerged as one popular and effective tool for causal inference in non-experimental studies, as they can help ensure that groups being compared are similar with respect to a…

This study examined 690 sophomore students who entered a small private institution at the beginning of the 2013-2014 academic year. It analyzed relationships among sophomore participation in co-curricular activities and academic performance measured by grade-point averages and persistence measured by continued enrollment. Significant relationships…

This study aimed to determine the level of self-directed learning readiness (SDLR) among undergraduate students at Saudi Electronic University in Saudi Arabia. Also, investigated were potential relationships between the level of self-directed learning readiness and selected demographic variables such as gender and specific college within the…

"A priori" power analyses allow researchers to estimate the number of participants needed to detect any effects of an intervention. However, power analyses are only as valid as the parameter estimates used. Effect sizes vary greatly depending on several study characteristics, including the nature of the intervention, the developer of the…

Mediation in multi-level data can be examined using conflated multilevel modeling (CMM), unconflated multilevel modeling (UMM), or multilevel structural equation modeling (MSEM). A Monte Carlo study was performed to compare the three methods on bias, type I error, and power in a 1-1-1 model with random slopes. The three methods showed no…

This study analyzed the meta-data collected from a honeypot that was run by the Federal Bureau of Investigation for a period of 5 years. This analysis compared the use of existing industry methods and tools, such as Intrusion Detection System alerts, network traffic flow and system log traffic, within the Open Source Security Information Manager…

Prior research pertaining to the behaviors that related to the acceptance and use of technology was primarily focused on individual end users with little concentration on the collective organizational perspective. Infrastructure changes in organizations developed as they transitioned from serviceable information technology systems to enterprise…

More than half of North Carolina's grade 3 students struggle with reading. The percentage of students scoring below proficient in reading at the end of grade 3 was 55 percent in 2017/18. That percentage has remained largely unchanged, at above 50 percent, since 2013/14, when North Carolina passed its K-3 Read to Achieve literacy act. Read to…

Background: Calls to improve student learning and increase the number of science, technology, engineering, and math (STEM) college and university graduates assert the need for widespread adoption of evidence-based instructional practices in undergraduate STEM courses. For successful reforms to take hold and endure, it is likely that a significant…

Background: In low-stakes educational assessments, test takers might show a performance decline (PD) on end-of-test items. PD is a concern in educational assessments, especially when groups of students are to be compared on the proficiency variable because item responses gathered in the groups could be differently affected by PD. In order to…

In many parts of the world, shadow education has become a major enterprise. Such is the case of the countries of the former Eastern Bloc, including the Czech Republic, which is in scope of this article. The study analyses the Internet supply of private tutoring lessons in academic subjects and assesses the micro- and macro-factors influencing the…

This article investigates the attitude toward mathematics among the students enrolled in the Foundation Year Programme at Nazarbayev University. The study is conducted quantitatively and an inventory developed by Tapia and Marsh II is adopted in this research. The inventory consists of 40 statements on the five-point Likert scale. Gender,…

The aims of this study were to compare the differences and determine the relationships between the scores obtained from Minnesota job-satisfaction and quality-of-life scales applied to males' ages 18 to 40 who participate in recreational activities and those who do not. The samples of the study consisted of 282 volunteers (148 of whom participate…

This study explored the worldviews of social work educators and two groups of social work students (European Americans and African Americans) using the Scale to Assess World Views to examine similarities and differences between the three groups. Within-group comparisons revealed African American and European American students showed similar…

The authors present an empirical analysis of what is taught in core micro-economics at a set of top U.S. doctoral economics programs. Their aim is to evaluate the diversity across programs and assess whether there are distinct "schools of thought" in graduate economics education. Their empirical findings reveal substantial, in fact,…
