Problem-solving strategies learned by physics undergraduates should prepare them for real-world contexts as they transition from students to professionals. Yet, graduate students in physics-intensive research face problems that go beyond problem sets they experienced as undergraduates and are solved by different strategies than are typically learned in undergraduate coursework. This paper expands the notion of problem solving by characterizing the breadth of problems and problem-solving processes carried out by graduate students in physics-intensive research. We conducted semi-structured interviews with ten graduate students to determine the routine, difficult, and important problems they engage in and problem-solving strategies they found useful in their research. A qualitative typological analysis resulted in the creation of a three-dimensional framework: context, activity, and feature (that made the problem challenging). Problem contexts extended beyond theory and mathematics to include interactions with lab equipment, data, software, and people. Important and difficult contexts blended social and technical skills. Routine problem activities were typically well defined (e.g., troubleshooting), while difficult and important ones were more open ended and had multiple solution paths (e.g., evaluating options). In addition to broadening our understanding of problems faced by graduate students, our findings explore problem-solving strategies (e.g., breaking down problems, evaluating options, using test cases or approximations) and characteristics of successful problem solvers (e.g., initiative, persistence, and motivation). Our research provides evidence of the influence that problems students are exposed to have on the strategies they use and learn. Using this evidence, we have developed a preliminary framework for exploring problems from the solver's perspective. This framework will be examined and refined in future work. Understanding problems graduate students face and the strategies they use has implications for improving how we approach problem solving in undergraduate physics and physics education research.

STEM outreach experiences provide aspiring scientists and healthcare professionals with opportunities to grow into new roles, integrate knowledge, and acquire soft skills. While STEM outreach publications often describe the outreach performed, few focus on how to establish strong partnerships, which are essential for outreach endeavors to succeed. Information on this is more important than ever before-grant agencies commonly require education and outreach plans that will reach a broader audience. Consequently, principal investigators who are not trained in education or outreach need tools to set up strong partnerships. To help fill this gap, here we outline the recommended steps for developing robust interdisciplinary STEM outreach programs that leverage institutional resources and community partnerships. This process yields strategic and sustainable opportunities for undergraduate students to learn as they engage with the STEM outreach team (students, faculty, university staff, and community partners) and the lay public. The outlined ideas broadly apply to creating outreach programs for trainees at any stage, not just undergraduates.

In order to support physics students in their future careers, there is a need to understand the relationship between undergraduate education and professional practice in physics-related fields. This study investigated high-level goal driven mathematical problem-solving activities that are found within two disciplinary cultures: physical science research labs in academia and photonics workplaces in industry. We conducted semistructured interviews with 10 Ph.D. students and 22 engineers and technicians. Math use in professional workplaces was characterized through an adaptation of epistemic games framework, which revealed six common epistemic games in these workplaces: conceptual math modeling, analyticalnumerical math modeling, design-oriented math modeling, fabrication, improving processes, and making meaning out of data games. The workplace-specific epistemic games capture the goals, starting and ending conditions, constraints and contextual features, moves, tools, and representations. The games involve a broad spectrum of math that ranges from arithmetic to computational modeling. The games reveal how goals and particular contextual features impact approaches to mathematical problem solving. The findings extend prior work on mathematical problem solving in physics to a new population of professional researchers, engineers, and technicians in their workplaces. The research may guide new approaches for developing problems and explicitly teaching problem solving in diverse physics contexts, which may additionally benefit undergraduate students' preparation for their future careers.

This study explores how graduate students learn to participate in collaborative international science research. As part of an NSF-funded program, 21 graduate students participated in extended research visits to China, completing surveys before and after traveling, and participating in semistructured interviews upon returning to the U.S. These survey and interview data were qualitatively analyzed to determine how graduate student participants defined collaboration and how they positioned their own research experience in an international context. Data were coded using emergent thematic analysis via a first pass open-coding to generate a comprehensive list of descriptive codes for collaboration and then a synthesis of these codes through discussions guided by theories of situated learning in communities of practice. Findings suggest that all graduate students emphasized the importance of effective communication in collaboration. Graduate students also described collaboration as including at least one of the following elements: complementary expertise, shared goals, joint publications, and mutual learning. These findings provide insight into graduate students’ experiences with collaboration, and, in turn, how to support graduate students so that they have successful international research experiences and collaborations with international colleagues.
