The use of propensity scores as a method to promote causality in studies that cannot use random assignment has increased dramatically since its original publication in 1983. While the utility of these approaches is important, the concepts underlying their use are complex. The purpose of this article is to provide a basic tutorial for conducting…

This article examines the extent to which participation in a large urban afterschool program had an impact on reducing participants' future juvenile crime rate. The research tracked the academic and juvenile crime histories for a sample of 6,000 students, including 2,000 participants in LA's BEST and 4,000 matched control students not…

Statway® is one of the Community College Pathways initiatives developed by the Carnegie Foundation for the Advancement of Teaching to promote students' progress beginning in developmental math to and through college math credit. Early descriptive results suggested that the Statway program has tripled the success rate for students in half the time…

For many students, the path to earning a postsecondary educational degree is often met with personal and social obstacles, but first-generation students are less likely to even enroll in postsecondary education and they have a higher probability for attrition when compared to their counterparts. The purpose of this study was to examine the…

This simulation study compared the utility of various discrepancy measures within a posterior predictive model checking (PPMC) framework for detecting different types of data-model misfit in multidimensional Bayesian network (BN) models. The investigated conditions were motivated by an applied research program utilizing an operational complex…

Often in sociology, researchers are confronted with nonnormal variables whose joint distribution they wish to explore. Yet, assumptions of common measures of dependence can fail or estimating such dependence is computationally intensive. This article presents the copula method for modeling the joint distribution of two random variables, including…

Student retention has garnered increased attentions in higher education. Drawing from various theoretical perspectives, researchers have developed multiple theoretical models to explain or predict student retention. Most models, however, were intended for traditional aged, full-time students at 4-year colleges or universities. The rapid growth of…

This article reports a systematic review and meta-analysis of studies that use regression discontinuity to examine the effects of placement into developmental education. Results suggest that placement into developmental education is associated with effects that are negative, statistically significant, and substantively large for three outcomes:…

Poverty is a well-established risk factor for behavior problems, yet our understanding of putative family mediators during early childhood (i.e., before age 5 years) is limited. The present study investigated whether the association between poverty and behavior problems during early childhood is mediated simultaneously by perceived parenting,…

This article presents a study on the variables promoting student retention in distance undergraduate courses at Federal University of Pará, aiming to help school managers minimize student attrition and maximize retention until graduation. The theoretical background is based on Rovai's Composite Model and the methodological approach is conditional…

The purpose of this quantitative study was to investigate the possible relationships between teacher characteristics and their decisions to recommend placement of African American male students for special education. The teacher characteristics (gender, race, age, years of teaching service, self-efficacy and teacher expectations) were the…

A professional development program (PSPD) was implemented to improve in-service secondary mathematics teachers' content knowledge, pedagogical knowledge, and self-efficacy in teaching secondary school statistics and probability. Participants generated a teaching resource website at the conclusion of the PSPD program. Participants' content…

A critical numeracy examination of Benford's Law suggests that our understanding of the integers is faulty. We think of them as equally likely to turn up as the first digit of a random real world number. For many real world data sets this is not true. In many cases, ranging from eBay auction prices to six digit numbers in Google to the…

This paper examines whether donations to colleges and universities are partly motivated by the desire of alumni to increase their children's admissions probabilities. The paper uses data from a single-sex college, so that only alums with a daughter would evince this motive. We find that alums with a teenage daughter, as opposed to a teenage…

There have been limited direct tests of the hypothesis that self-injurious behavior (SIB) regulates arousal. In this study, two autonomic biomarkers for physiological arousal (heart rate [HR] and the high-frequency [HF] component of heart rate variability [HRV]) were investigated in relation to SIB for 3 participants with intellectual…
