A comprehensive graduate teaching assistant (GTA) training program in mathematical sciences designed at one institution is being adapted and replicated at two peer institutions. Using a case study approach, this paper outlines the development of the program components, which include a first-year teaching seminar, peer mentoring and support from a peer TA Coach, a Critical Issues in STEM Education seminar, and K–12 outreach to inform understanding of the pipeline. Additionally, adaptations due to institutional context and the impact of the Covid-19 pandemic are described. Implications for components of the comprehensive program, based on GTA-provided feedback, are discussed. [ABSTRACT FROM AUTHOR]

In this paper, I analyze the impact of culture and metaphor on cryptology education. I will compare and contrast the historically grounded metaphors of cryptology-is-warfare and encryption-is-security to a set of counter-metaphors: cryptology-is-privacy and encryption-is-communication. Using this explicit understanding of conceptual metaphor, I present design recommendations and metaphorizing activities for educators building their undergraduate cryptology course.

Math anxiety and academic distress, two interrelated forms of psychological stress, are pervasive problems for undergraduate mathematics students. Most of the research in this area has taken a broad view of the impact this stress has on students' learning across an entire course or, more broadly, the entire curriculum for their degree. To complement this existing body of research, this paper serves a dual purpose: First, to provide insight into undergraduate students' day-to-day classroom stress, and secondly, to explore fitness trackers as a tool for in situ detection of student anxiety or stress in the classroom. To accomplish the first objective, we conduct a phenomenographic analysis to explore the variation in 29 students' reported experiences of psychological stress within a session on roots of polynomial functions. We identified 7 categories of description. For the second objective, we recorded the students' heart rate during the same lesson. We clustered students heart rate variability plots according to our categories of description and employed a logistic regression model to estimate the probability that a student will report experiencing psychological stress given their heart rate variability. Our results show that fitness trackers can produce measures that serve as a predictor of self-reported emotional change. [ABSTRACT FROM AUTHOR]
