This tutorial presents recent advancements to the Extreme-scale Model Exploration with Swift (EMEWS) framework. EMEWS is a high-performance computing (HPC) model exploration (ME) framework, developed for large-scale analyses (e.g., calibration, optimization) of computational models. We focus on three new use-inspired EMEWS capabilities, improved accessibility through binary installation, a new decoupled architecture (EMEWS DB) and task API for distributing workflows on heterogeneous compute resources, and improved EMEWS project creation capabilities. We present a complete worked example where EMEWS DB is used to connect a Python Bayesian optimization algorithm to worker pools running both locally and on remote compute resources. The example, including an R version, and additional details on EMEWS are made available on a public website.</p>","PeriodicalId":74535,"journal":{"name":"Proceedings of the ...

With the goal of finding not only the input parameter settings but also the random seeds that are consistent with the ground truth, we propose a class of Gaussian process (GP) surrogates along with an optimization strategy based on Thompson sampling.

Repast4Py is a Python agent-based modeling framework that provides the ability to build large, MPI-distributed agent-based models (ABM) that span multiple processing cores. Simplifying the process of constructing large-scale ABMs, Repast4Py is designed to provide an easier on-ramp for researchers from diverse scientific communities to apply distributed ABM methods. We will present key Repast4Py components and how they are combined to create distributed simulations of different types, building on three example models that implement seven common distributed ABM use cases.

Sato","doi":"10.3998/tia.406","DOIUrl":"https://doi.org/10.3998/tia.406","url":null,"abstract":"The Association of American Colleges and Universities calls for improvements in teaching preparation in graduate programs as a transferable skill for future faculty. However, the amount of institutional and faculty support for these programs is limited. For the relatively few programs that exist, rarely do they have their outcomes assessed in a data-driven manner. This is disconcerting considering that participation in professional development can improve work-life balance, and graduate students often work long hours, suffer from mental health issues, and face increasing career competition. In this case study, we explore how two teaching development programs impacted pedagogical knowledge, perceived quality of life, and sense of community in graduate students at the University of California, Irvine. Using a mixed methods approach, we demonstrate that participants in our introductory quarter-long Developing Teaching Excellence course increased their pedagogical knowledge, and participants in both our introductory course and our advanced year-long Pedagogical Fellows Program reported having improved quality of life and sense of belonging. Most commonly, participants framed these pedagogical programs/courses as providing a safe and inclusive space to explore teaching in an interdisciplinary manner; a network of like-minded and supportive peers; and an opportunity to develop greater confidence in teaching, mentorship, and other aspects of graduate life such as conducting research and entering the academic job market. Taken together, our results indicate that providing a structured, nurturing environment for graduate students to develop their pedagogical knowledge and practice may lead to improved quality of life and sense of belonging.","PeriodicalId":74535,"journal":{"name":"Proceedings of the ...

Blankenship","doi":"10.3998/tia.137","DOIUrl":"https://doi.org/10.3998/tia.137","url":null,"abstract":"Institutions are redesigning gateway courses—lower-division courses known to create student success bottlenecks—to influence persistence and completion goals. These initiatives, student success course redesigns (SSCR), are specialized versions of course design institutes (CDIs). This investigation into SSCRs uses content analysis to examine the implementation plans created during a SSCR. Results demonstrated that the majority of the strategies planned focused on the Learning key performance indicator (KPI), and the minority of the planned-for strategies focused on the Monitoring Student Performance KPI. A more granular analysis of the Learning strategies revealed five themes: Content, Assessment, Pedagogy, Syllabus, and Student Success. Additional results indicated the majority of planned strategies would occur out of class, and disciplinary differences between science, technology, engineering, and mathematics (STEM) and non-STEM faculty for pedagogical and content design changes. Results also demonstrated a need for more faculty to utilize actionable language for course redesign strategies. Moreover, the implementation plans provided useful assessment feedback of the CDI itself.","PeriodicalId":74535,"journal":{"name":"Proceedings of the ... Winter Simulation Conference.

Leveraging Collaboration and Peer Support to Initiate and Sustain a Faculty Development Program 利用协作和同伴支持发起和维持教师发展计划

In this study, we illustrate how underfunded programs can leverage peer collaboration and support to initiate productive, formal systems of assistance for faculty by describing a number of such programs developed by and/or coordinated by our CTL. Moreover, we propose that sustainable programs, especially at small liberal arts institutions, must include a strong component of peer networking and in-house expertise rather than relying on outside consulting services. In a climate of shrinking dollars, CTLs can still perform some key roles effectively while continuing to advocate for more adequate funding.","PeriodicalId":74535,"journal":{"name":"Proceedings of the ...

In this article we discuss how our dual ED centers pivoted during the sudden switch to online learning, highlighting how we overcame challenges such as a small staff, tight timelines, and faculty anxieties. Particularly, we explore how we adapted to the university’s investment in technologically advanced Hybrid-Flexible (HyFlex) classroom spaces and utilized a multi-pronged team approach to provide effective and timely ED to faculty. By identifying key faculty leaders, identifying multiple sources of data, and using multiple modalities, we supported the faculty in their mission to effectively serve their students during this difficult and stressful time. In pivoting from a triage approach to more tactically focused development, the two ED centers discovered that they could more effectively serve faculty (and by extension students) by shattering the structural silos that had previously defined them and instead working as a unified entity.","PeriodicalId":74535,"journal":{"name":"Proceedings of the ...
