Over the last two decades, statistics educators have made important changes to introductory courses. Current guidelines emphasize developing statistical thinking in students and exposing them to the entire investigative process in the context of interesting research questions and real data. As a result, many concepts (confounding, multivariable…

Randomized trials are often conducted with separate randomizations across multiple sites such as schools, voting districts, or hospitals. These sites can differ in important ways, including the site's implementation, local conditions, and the composition of individuals. An important question in practice is whether--and under what…

Meta-analyses combine the results of multiple studies of a common question. Approaches based on effect size estimates from each study are generally regarded as the most informative. However, these methods can only be used if comparable effect sizes can be computed from each study, and this may not be the case due to variation in how the studies…

Working in collaborative groups has been shown to have beneficial outcomes; however, these benefits are linked to the quality of group member interactions. "Heedful interrelating," which entails interacting with sensitivity to the task at hand while paying attention to how one's actions affect overall team functioning, is theorized to be…

Higher education students experience heightened levels of stress and anxiety, and report experiencing negative thoughts and emotions, which influence information retention and recall. In a randomized experiment, we assigned participants to either a mindfulness meditation or an audiobook listening condition, and recorded the information recalled…

The technology policies included on instructors' syllabi vary greatly and, in some cases, may unfavorably influence students' perceptions of the instructor. To examine this hypothesis, we randomly assigned college students enrolled in psychology courses at two different institutions (N = 163) to groups in which they viewed different syllabi for a…

This paper presents the results of a study aimed at exploring the possibilities Twitter offers for pronunciation instruction. It investigates the potential of a Twitter-based approach based on explicit instruction and input enhancement techniques to help English Foreing Language (EFL) learners improve their pronunciation of segmental and…

Guided by assumptions from the cognitive-affective theory of learning with media, we conducted a teaching experiment to corroborate past correlational research that suggested instructor misbehaviors, in the form of antagonism toward students, impede students' cognitive learning. Participants were 472 undergraduate students who were randomly…

Background: Students of clinical psychology and medicine experience high levels of mental distress and low levels of life satisfaction. Using adaptive coping strategies can modify the negative effect of stressors on health. Mindfulness, it has been claimed, more adaptive coping with stress, yet few studies have investigated whether mindfulness…

The studies regarding using a cross sectional view of speech organs enriched with attention cueing and written text to probe learners' learning efficiency and behavior through mobile phones is scant. The purpose of this study was to examine whether the presence of attention cueing can benefit learners with different amounts of prior knowledge in…

To better understand the nature of impairment resulting from attention-deficit/hyperactivity disorder (ADHD) for students in a post-secondary education (PSE) setting, the authors analyzed the symptoms and associated impairment of 135 students with a diagnosis of ADHD who were recruited via Student Disability Services in Canadian post-secondary…

The present study examined parent-teacher congruent communication within conjoint behavioral consultation (CBC). Specifically, the study purpose was to determine the extent to which congruence in parent-teacher communication (i.e., the degree to which parents and teachers view their communication in a similar fashion) moderated CBC's effects on…

Community colleges nationwide are looking for solutions to help students complete developmental (remedial) math--a known barrier to graduation. Some are offering computer-assisted, modular developmental math courses that allow students to earn credits incrementally and move through the curriculum at their own pace. One of these modularized…

Learning environments commonly offer aids to address learners' lack of knowledge or skills. However, learners are not or sub-optimally using these aids when these are non-embedded or segregated (Aleven, Stahl, Schworm, Fischer, & Wallace, 2003; Clarebout & Elen, 2006). This lack of optimal usage has been related to variables as…
