Different educational modalities can affect students in learning challenging engineering concepts. Studies that specifically measure students’ conceptual learning gains have been conducted in face-to-face (F2F) and online modalities, but few direct comparisons have been reported. In this study, we collected data from undergraduate students enrolled in introductory materials science courses...
Community-Engaged Research (CEnR) is a strategy for integrating community needs, priorities, and concerns into the research design, data collection strategies, and subsequent analysis of data. CEnR shares similar properties with both citizen science and community-based participatory research (Woolley et al., 2016). Before the COVID-19 pandemic, CEnR occurred predominantly via face-to-face...
1. Multidimensional trait frameworks are increasingly used to understand plant strategies for growth and survival. However, it is unclear if frameworks developed at a global level can be applied in local communities and how well these frameworks—based largely on plant morphological traits—align with plant physiology and response to stress.

I am a physics education researcher. My ‘laboratory’ is a year-long Introductory Algebrabased Physics sequence taught at Oregon State University (OSU). While not technically a hybrid class, it has most of the aspects of a hybrid learning environment, as the course is “flipped,” and includes a combination of pre-lecture online...
Massive Open Online Courses (MOOCs) have generated considerable excitement and considerable skepticism since their recent inception (e.g., Kim, 2014; Perna et al., 2014). By fall 2015, approximately 35 million people had participated in 4200 courses offered by over 550 institutions (Shah, 2015). In addition to MOOCs’ potential for expanding access...
As the number of students and faculty involved in online learning in recent decades has increased, we recognize that there is a limited understanding of how learners react, interact, behave, and are served by the various components in the information delivery processes. When learning online without an instructor present in...
Teacher preparation programs must ensure that course and clinical work provide a solid practice and theoretical foundation upon which new teachers can grow and thrive. Part of this process is the need for theory and research learned in coursework to mesh and enrich classroom practices. In this study we interview...
Prior research has suggested that homework activities that encourage learners to think more conceptually about to-be-learned material can have positive benefits on overall content learning. Can such activities be implemented successfully in online coursework, and does it produce the anticipated benefit? In two sections of an online Psychology course, participants...
Everyone involved in online education talks about community – what is it, how is it created, do students really want it? Most researchers now agree that online education is enhanced through a greater sense of community within the online classroom; however, the factors that make for a substantive and quality...
As an Oregon State Ecampus Research Fellow, I designed and initiated a research study that aimed to: 1) investigate tools and techniques for engaged, experiential online learning with undergraduate philosophy students and 2) propose disciplinespecific criteria for evaluating the impact of these pedagogical interventions. The study was designed to answer...
While online Computer Science (CS) degree programs can attract diverse students, many students still feel excluded in the online CS classroom. One reason students feel excluded is because their gender is underrepresented among their classmates. At Oregon State University, only 27% of online CS students are women. This is better...
Online teaching and learning has become an increasingly important aspect of the educational mission of universities. In person, teachers have time-tested tools for assessing student ability, including a wealth of verbal and nonverbal communication. The online format provides a wealth of data, and promises—but may not yet deliver—useful tools for...
Writing within Discipline is a pedagogical model that aims to engage students in active learning and to develop critical thinking and writing skills within the norms of a particular discipline. However, lack of faculty time for grading writing products impedes its broader implementation. Web based peer review programs have been...
The literal distance inherent in online education can be an important difference between it and traditional classroom settings, such that proximate, on-site learning is thought to be where experiential, transformative education happens (Cohen, 2013). Yet it is possible that some of the most compelling, effective aspects of traditional, proximate education...
The Earth is warming at a seemingly unstoppable rate, a virus is ravaging the world, and international tensions are ever-present. This brings me to wonder, how will we survive in the future? And as an artist that question turns into: what will we look like in the future? Partnered with...

We explore one numerical method for dealing with uncertainty quantification, stochastic collocation. We adapt this method for the uncertain kinematic magnetohydrodynamic system. We then demonstrate well-posedness of the uncertain forward problem. We also describe the method in detail, and perform an error analysis of the method, describing the necessary assumptions...
We discuss an efficient numerical method for the uncertain kinematic magnetohydrodynamic system. We include aleatoric uncertainty in the parameters, and then describe a stochastic collocation method to handle this randomness. Numerical demonstrations of this method are discussed. We find that the shape of the parameter distributions affect not only the...
We discuss the well-posedness of the forward problem for the magnetohydrodynamic system with the inclusion of the ion-slip parameter. We also demonstrate the convergence of a parameter estimation scheme. Focusing on power-generation, we implement and the validate a numerical model with an engineering multi-physics software, COMSOL, using ideal-power equations. We...

According to a 2017 Pew Research Study, 44% of adults in America say that they do not feel informed enough about science to understand news and new discoveries discussed on the media (Funk et al. 2019). This is concerning, because adults are not just passive consumers of media; among other...
This project aims to challenge traditional beliefs about the emotional and psychological meanings of colors, which are often limited in the Western world. The psychology of color is heavily present in nearly every aspect of our lives, and this continual reinforcement of each color’s assigned meaning ignores and discourages the...
Multi-party computation (MPC) is a field of study focused on devising cryptographic protocols that allow participants to learn the output of some function of their private inputs without trusting a third party to perform the computation. This is usually done at a large scale between data centers, with little emphasis...
In this thesis, I aim to bring two ancient spiritual guides into dialogue with each other and with modern psychology: the Bodhisattvacaryāvatāra by Śāntideva of the Mahāyāna Buddhist tradition and The Ladder of Divine Ascent by St. John Climacus of the Christian tradition. I draw from Tibetan Buddhist commentaries on...
