We encounter variables with little variation often in PER due to the demographics of physics and the questions we ask. For example, in course completion studies, most students will earn high enough grades to pass the course. Yet, little work has examined how to analyze such data. Therefore, we conducted a simulation study using logistic regression, penalized regression, and random forest. We systematically varied the fraction of positive outcomes, feature imbalances, and odds ratios. We find the algorithms treat features with the same odds ratios differently based on their imbalance and the outcome imbalance. While none of the algorithms solved the problem, some reduced the scale of the problem. Our results suggest that PER studies may contain false negatives when determining which variables are related to an outcome. We propose recommendations for researchers and then illustrate these by predicting which applicants will be admitted to a graduate physics program.

Addressing Rare Outcomes in PER Quantitative Studies

Course grades are concrete outcomes with real-world consequences for students. To what extent are grades, as they are currently awarded, consistent and fair? &nbsp;Higher Educational Institutions are sitting on vast amounts of data that can help us to gain more insight into these questions and perhaps lead us to more desired outcomes. I will discuss three data analytics projects we conducted. First, I will examine how student-level factors such ACT score and demographic group effect grades and exam vs. non-exam grade components. This will reveal demographic disparities. &nbsp;Next, by considering measures of prior preparation, such as ACT scores and prior course grade, I will apply the concept of differential prediction to examine the extent to which grading is consistent between sections, instructors, and semesters, and further examining how consistency between these groups extends to the demographic factors of gender and race. Areas of concern are found for all factors. &nbsp;

Consistency and Fairness in Introductory Physics Course Grades

The Frayer Model is a reading strategy presented as a graphic organizer.&nbsp; Researchers have shown that the approach promotes vocabulary development for specified scientific terms among high school students.&nbsp; This empirical research study sought to explore a way to develop scientific vocabulary among English Language Learners and Students with Disabilities in a synchronous learning environment between in-person and virtual learners by implementing the Frayer Model in a digital format using Google Slides. Google Slides settings allow each student to interact independently with the content while simultaneously sharing with the group.&nbsp; A convenience sample consisted of eleven high school students, seven in-person learners, and four virtual learners.&nbsp; Daily bellwork composed of one question provided post data to assess retention and understanding.&nbsp; Observational data captured in reflective logs shows increase active learning, and students form personal connections between the scientific terms and their personal experiences.

Often the skills required to use the Unix/Linux command line are perceived as old-fashioned, difficult to learn, and unnecessary. However, the Linux command line is an extraordinarily flexible environment for programming, data reduction and analysis, simulation, and visualization, and is thus in wide use throughout the physics research community and beyond. These skills are surprisingly accessible to students. In this talk, I will argue that the command-line environment is a pedagogically beneficial environment for students to learn computational physics, with advantages both within the classroom and beyond it, and demonstrate some of the tools and methods the computational physics students at Syracuse use for simulation, visualization, animation, and data analysis.
