Is there a crysis in Cosmology?

AAPT® is a strong professional physics science society dedicated to the pursuit of excellence in physical science education.

Winter and Summer National Meetings:
These National Meetings, held each winter and summer, are opportunities for members, colleagues, and future physicists from around the world to:

- participate in physics workshops
- meet and greet other physics educators
- form networks nationally and locally
- engage exhibitors and learn about the latest physics resources
- discuss innovations in teaching methods
- share the results of research about teaching and learning.

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

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.
