Gathering Nuanced Data For Understanding Student Withdrawals, Beverly Wood, Emily Faulconer, Darryl Chamberlain

Publications

This white paper argues that the current system for collecting data on student withdrawals at their university is inadequate. The current withdrawal form lacks detail and makes it difficult to understand the reasons why students leave courses. This is a problem because it hinders efforts to improve student persistence (completion of courses).

Key Points:

• The university's strategic plan emphasizes student experience, enrollment management, and academic excellence. High withdrawal rates undermine these goals.
• Researchers developed a research-based nuanced framework for understanding withdrawal reasons.
• The current withdrawal form offers limited options for students to explain why they are withdrawing; the current form …

A Note On Umbilic Points At Infinity, Brendan Guilfoyle

Publications

In this note a definition of umbilic point at infinity is proposed, at least for surfaces that are homogeneous polynomial graphs over a plane in Euclidean 3-space. This is a stronger definition than that of Toponogov in his study of complete convex surfaces, and allows one to distinguish between different umbilic points at infinity. It is proven that all such umbilic points at infinity are isolated, that they occur in pairs and are the zeroes of the projective extension of the third fundamental form, as developed in Guilfoyle and Ortiz-Rodríguez (Math Proc R Ir Acad 123A(2), 63–94, 2023). A geometric …

Exploring Practical Measures As An Approach For Measuring Elementary Students’ Attitudes Towards Computer Science, Umar Shehzad, Mimi M. Recker, Jody E. Clarke-Midura

Publications

This paper presents a novel approach for predicting the outcomes of elementary students’ participation in computer science (CS) instruction by using exit tickets, a type of practical measure, where students provide rapid feedback on their instructional experiences. Such feedback can help teachers to inform ongoing teaching and instructional practices. We fit a Structural Equation Model to examine whether students' perceptions of enjoyment, ease, and connections between mathematics and CS in an integrated lesson predicted their affective outcomes in self-efficacy, interest, and CS identity, collected in a pre- post- survey. We found that practical measures can validly measure student experiences.

From Crossing Campus To Crossing Continents: Faculty, Chair, And Global Partner Perspectives On An International Sabbatical, Emily Faulconer, Beverly L. Wood, Stephen George-Williams

Publications

A sabbatical – a period of paid leave granted to faculty for research or study - is a construct in higher education that has experienced ebbs and flows in its favorability, though there are persistent arguments that it is important for research-active faculty (Pietsch, 2011). Early career faculty are focused on achieving tenure as this is high stakes at most institutions. Once tenure is achieved, the next goalpost is full professor. The day-to-day responsibilities of faculty can distract from and dilute efforts aimed at strategic planning, long-term planning, and reflection necessary to achieve this level of promotion. So it follows …

A Crosswalk Of Digital Storytelling And Multilingual Learning, Nicole Ferguson-Sams, Emily Howell, Rebecca Kaminski, Victoria Pennington, Mihaela Gazioglu, Kavita Mittapalli

Publications

This study draws on the practice of digital storytelling (DST) to address the limited use of technology in middle school multilingual classrooms. Through critical and multiliteracy frameworks, DST can help create a more engaging and inclusive learning environment that supports the literacy development of multilingual learners (MLs). After reviewing and synthesizing empirical studies on DST as it applies to the middle school years, we provide a crosswalk focusing on four core areas: content, context, communication and language, and student identity. The crosswalk reveals how DST integrates Web 2.0 technology and promotes language and literacy development among middle school MLs.

Findings show that although the content of PD has covered foundational literacy areas, such as vocabulary and comprehension, more attention is needed on integration of culture and MLs’ linguistic repertoires. Results also show that PD …

Democratic Policing, Building Trust, And Willingness To Call 911: Examining The Relationship Between Law Enforcement Legitimacy And Calling The Police, Kyle Mclean, Brian Lee Miller, Andrew S. Pyle, Olivia Bauwens

Publications

Recent debates over policing have centered on the proper role of policing in society. Using the lenses of democratic policing and police legitimacy, we suggest that individuals’ willingness to call the police is one method for understanding the public’s consent to be policed and their view of the appropriate role of policing. This simple relationship is further complicated by differential relationships between willingness to cooperate with the police and four typologies of police legitimacy: trustworthiness, normative alignment, obligation to obey, and traditional legitimacy. Using the pretest and posttest of a survey vignette, we show that (1) individuals who legitimate the …

Density And Magnetic Field Asymmetric Kelvin‐Helmholtz Instability, Xuanye Ma, Peter Delamere, Katariina Nykyri, Antonius Otto, Stefan Eriksson, Lihui Chai, Brandon Burkholder, Andrew Dimmock, Yu-Lun Liou, Shiva Kavosi

Publications

The Kelvin‐Helmholtz (KH) instability can transport mass, momentum, magnetic flux, and energy between the magnetosheath and magnetosphere, which plays an important role in the solar‐wind‐ magnetosphere coupling process for different planets. Meanwhile, strong density and magnetic field asymmetry are often present between the magnetosheath (MSH) and magnetosphere (MSP), which could affect the transport processes driven by the KH instability. Our magnetohydrodynamics simulation shows that the KH growth rate is insensitive to the density ratio between the MSP and the MSH in the compressible regime, which is different than the prediction from linear incompressible theory. When the interplanetary magnetic field (IMF) …

Publications

Highly diverse agroecosystems are increasingly of interest as the realization of farms’ invaluable ecosystem services grows. Simultaneously there has been an increased use of uncrewed aerial systems (UAS) in remote sensing as drones offer a finer spatial resolution and faster revisit rate than traditional satellites. With the combined utility of UAS and the attention on agroecosystems, there exists an opportunity to assess UAS practicality in highly biodiverse settings. In this study, we utilized UAS to collect fine-resolution 10-band multispectral imagery of coffee agroecosystems in Puerto Rico. We created land cover maps through a pixel-based supervised classification of each farm and …

Sportsmanship Attitudes As A Moderator Of The Relationship Between Team Identification And Spectator Aggression Attitudes, Andrew Rudd, Sarah Stokowski

Publications

The National Collegiate Athletic Association has long been concerned with the prac­tice of sportsmanship. However, frequent displays of spectator aggression at collegiate sport events demonstrates a grave contradiction. Fans level of team identification is considered a key influence on spectator aggression. Alternatively, sport marketers have found that team identification plays a vital role in fan consumption (e.g., tickets and merchandise). In the interest of reducing aggressive fan behavior without damp­ening the sport managers' need for highly identified college sports fans, we sought to assess how spectator sportsmanship attitudes might serve to moderate the relationship between team identification and spectator aggression …
