We examined whether U.S. schools systemically discriminate when suspending or otherwise disciplining students with disabilities (SWD). Eighteen studies met inclusion criteria. We coded 147 available risk estimates from these 18 studies. Of four studies including individual-level controls for infraction reasons, over half of the available estimates…

This study used propensity score matching to compare two online courseware systems intended for use as supplements to either face-to-face or online courses. One courseware system focused on adaptive features available to students while completing assignments; whereas the other system was an interactive courseware that provided embedded media…

In everyday life, people encounter smaller rewards with higher probability than larger rewards. Do people expect this reward--probability regularity to hold in experimental settings? To answer this question, we tested whether people's behavior in probability judgment tasks is affected by the correlation between reward size and reward…

Categorical perception (CP) effects manifest as faster or more accurate discrimination between objects that come from different categories compared with objects that come from the same category, controlling for the physical differences between the objects. The most popular explanations of CP effects have relied on perceptual warping causing…

This paper investigates the degree to which different variables affect the completion of a Massive Open Online Course (MOOC). Data on those variables, such as age, gender, English proficiency, education level, and motivation for course enrollment were first collected through a pre-course survey. Next, course completion records were collected via…

Sexual assault on college campuses has been a longstanding problem in the USA. Unfortunately, relatively little has been done to look at the characteristics of these attacks and how they might relate to knowledge of sexual assault policies, participation in sex education courses, beliefs toward sexual violence, and willingness to intervene if an…

Traditionally, a college grade point average (GPA) of 2.00 or higher has signified that a student has made acceptable academic progress and avoided academic probation. However, having a 3.00 or higher has signified a level of success that is often required for admission to graduate school, maintaining a scholarship or enrollment in an honors…

The current study was conducted with the goal of helping to address the research gap of improving preservice teachers' pedagogical knowledge about probability by investigating how preservice teachers explored concepts of probability during aleatoric music composition, as well as their contemplation process during follow-up reflections focused on…

This study examined caregiver-reported medically-attended injuries among 30-68 month old children with autism spectrum disorder (ASD) compared to general population (POP) and non-ASD developmental disorders (DD) controls in the Study to Explore Early Development. Injuries were common in ASD cases (32.3%) as well as POP (30.2%) and DD (27.8%)…

The National Study of Protest Events (NSPE) employed hypernetwork sampling to generate the first-ever nationally representative sample of protest events. Nearly complete information about various event characteristics was collected from participants in 1,037 unique protests across the United States in 2010 to 2011. The first part of this article…

The Monty Hall Dilemma (MHD), made famous by the television game show Let's Make a Deal, can be an effective teaching tool with wide ranging behavioral science applications. The format and history of the problem are presented as well as experimental data and variations on the original design. Strategic game playing choices are discussed from…

Producers and consumers of test scores are increasingly concerned about fraudulent behavior before and during the test. There exist several statistical or psychometric methods for detecting fraudulent behavior on tests. This paper provides a review of the Bayesian approaches among them. Four hitherto-unpublished real data examples are provided to…

Purpose: This article focuses on toddlers' revisions of the sentence subject and tests the hypothesis that subject diversity (i.e., the number of different subjects produced) increases the probability of subject revision. Method: One-hour language samples were collected from 61 children (32 girls) at 27 months. Spontaneously produced, active…

Educational resources can be easily found on the Web. Most search engines base their algorithms on a resource's text or popularity, requiring teachers to navigate the results until they find an appropriate resource. This makes searching for resources a tedious and cumbersome task. Specialized repositories contain resources that are annotated with…

Wong et al. (2014) conducted a comprehensive review of the literature published between 1990 and 2011 to identify practices for children, adolescences, and young adults diagnosed with autism spectrum disorders (ASD) that had sufficient empirical support to be considered evidence-based. Behavior momentum interventions (BMI), or high-probability…
