“What Makes It Eigen-Esque-Ish?”: A Form-Function Analysis Of The Development Of Eigentheory Concepts In A Quantum Mechanics Course, Megan Wawro, Kaitlyn Stephens Serbin

School of Mathematical & Statistical Sciences Faculty Publications

Eigentheory concepts are central in mathematics and physics; they serve multiple functions, such as symbolizing physical phenomena and facilitating mathematical computations. Words and meanings associated with eigentheory develop and vary over time, as do their associated symbols. In this study, we investigate how “eigen” develops over time in one quantum mechanics course by analyzing form-function relations (Saxe, 1999) for eigentheory concepts over 22 class sessions. We share results concerning our microgenetic and ontogenetic analyses of the creation of form-function relations and their shifts over time by characterizing the continuity and discontinuity of the various functions and forms associated with concepts …

Investigating Social Presence In Collaborative Keys For Asynchronous Courses, Lily P. Cook

Master's Theses

Asynchronous virtual courses have become increasingly popular in the years following the global Covid-19 pandemic. These courses, with no set meeting schedule, offer flexibility to both students and instructors, but pose challenges for developing a collaborative learning environment.

What Happens After They Leave The Ed? Following Up Acute Asthma Exacerbations After Changes In Clinical Practice Guidelines For Treatment, Phillip S. Wozniak, Jade B. Tam-Williams

Research Days

In 2022, Children’s Mercy Hospital (CMH) implemented a new clinical practice guideline (CPG) recommending single-dose dexamethasone as the first line oral steroid for treatment of mild to moderate acute asthma exacerbations. We assessed the impact of this CPG change on readmission rates after discharge from emergency department/urgent care (ED/UC). We hypothesized that single-dose dexamethasone would be non-inferior to a 5-day course of prednisone/prednisolone with respect to 7-day and 30-day acute care readmission rates and need for additional outpatient steroid courses.
