We analyze the impact of COVID-19 diagnoses on student grades, retention, and on-time graduation at a large public university. Even though COVID-19 rarely causes major health complications for a typical university student, diagnosis and quarantine may cause non-trivial disruptions to learning. Using event study analysis, we find that a COVID-19…

At the University of Pittsburgh at Greensburg, commuter students make up the majority of the currently enrolled student population. The majority population has expressed their dissatisfaction about co-curricular and social activities and a diminished sense of belonging and inclusion. The focus of this dissertation is on the Greensburg Experiences…

Teachers' classroom management practices are an essential aspect of supporting student engagement, yet they often vary in response to changing conditions in the classroom. This study explored the variability within middle school teachers' observed practice and their students' engagement as a function of contextual factors. Observers visited…

Recent research in numerical cognition has begun to systematically detail the ability of humans and nonhuman animals to perceive the magnitudes of nonsymbolic ratios. These relationally defined analogs to rational numbers offer new potential insights into the nature of human numerical processing. However, research into their similarities with and…

Demonstrating academic libraries' contribution to institutional outcomes and strategic initiatives can be challenging, particularly in determining what library activities can be consistently and accurately assessed in ways that empirically demonstrate library value and impact. To address this challenge, the Indiana University Bloomington Libraries…

Purpose: Spectral modulation detection is an increasingly common assay of suprathreshold auditory perception and has been correlated with speech perception performance. Here, the potential effects of stimulus duration and stimulus presentation level on spectral modulation detection were investigated. Method: Spectral modulation detection…

Background: Leisure time for adults with learning disabilities is often diversionary and spent doing passive, solitary or family-orientated activities. Befriending, as a hybrid "natural" support, may help adults with learning disabilities overcome the barriers to participation in nonsegregated leisure. Materials and methods: Four case…

The identification of rapid guessing is important to promote the validity of achievement test scores, particularly with low-stakes tests. Effective methods for identifying rapid guesses require reliable threshold methods that are also aligned with test taker behavior. Although several common threshold methods are based on rapid guessing response…

It is well established that the temporal proximity of two events is a fundamental cue to causality. Recent research with adults has shown that this relation is bidirectional: events that are believed to be causally related are perceived as occurring closer together in time--the so-called temporal binding effect. Here, we examined the developmental…

A method based on oblique projection is presented for construction of sundials. The derived formulas are classical, but usage of vectors and projections renders a coherent presentation rather than a number of special cases. The presented work is aimed to be useful for those taking a beginning module on vector algebra.

Textbook passages commonly include elaborations (details supporting main ideas) with the assumption that elaborations will improve learning of the main ideas. However, elaborations increase text length, which subsequently increases the reading time of that text. These observations lead to the two focal questions of interest in the current study:…

The "2020 Fall Enrollment Report" contains the following tables, charts, and figures: (1) System Duplicated and Institutional Headcount Enrollments; (2) Full Time and Part Time Headcount; (3) High School Students Enrolled in College Courses, Beginning Freshmen and Transfer Students, Developmental and Collaborative Course Enrollments; (4)…

Universities globally are aspiring to grow through investing in the delivery of online learning programmes. However, the attrition rate for online learning is high. It has been noted that those students with a sense of belonging to their course experience increased enjoyment and reduced anxiety and are therefore less likely to withdraw. Yet too…

TransferBOOST (Bachelor's Opportunity Options that are Straightforward and Transparent) is a multi-year state-level initiative developed to provide students with affordable, quality, well-supported two- to four-year pathways. On average, 43 percent of credits are lost nationwide through the transfer process. Recognizing that today's students…
