Abstract

Course-based undergraduate research experiences (CUREs) enhance student retention in STEM, particularly among students who belong to historically excluded communities. Yet the mechanisms by which CUREs contribute to student integration and persistence are poorly understood. Utilizing the Tripartite Integration Model of Social Influence (TIMSI), this longitudinal study examines how Tiny Earth, an antibiotic-discovery CURE, impacts students scientific self-efficacy, scientific identity, endorsement of scientific community values, and intentions to persist in science. The study also explores how gains in TIMSI factors vary as a function of student demographics and course characteristics. Results of pre-and post-course measurements show that scientific self-efficacy and identity increased among students in Tiny Earth, and some student demographics and course characteristics moderated these gains. Gains in scientific self-efficacy, identity, and values correlated with gains in persistence intentions, whereas student demographics and course characteristics did not. Results of this study show that the Tiny Earth CURE enhanced students integration into the scientific community, which was linked to intentions of students of both historically underrepresented and majority groups to persist in STEM. We discuss how courses that provide opportunity to learn science skills in the context of a CURE can contribute toward enlarging and diversifying the STEM workforce.

Evaluating Large Language Models as Tools to Navigate Researchers in Rapidly Evolving Research Landscapes: A Case Study in Cancer Drug Response Prediction

Large Language Models (LLMs) have emerged as promising tools for assisting researchers in automating and accelerating the synthesis of literature reviews. However, their reliability is a significant concern due to issues like factual inaccuracies and hallucinations. The key question is whether LLMs can reliably provide comprehensive, up-to-date overviews and analyses. This study evaluates the performance of three leading LLMs (OpenAI's ChatGPT, Google's Gemini, and DeepSeek) on the complex task of generating a comprehensive survey paper on deep learning for cancer Drug Response Prediction (DRP). By testing both standard and Deep Research (DR) / Deep Think (DT) modes of LLMs with prompts of varying detail, this paper assesses key academic dimensions, including reference management, content quality, and analytical depth. Key findings reveal that while DR modes of LLMs significantly improve reliability by eliminating hallucinations, performance variations exist across models and prompts. A trade-off between reference quantity and integration quality was observed, and even the best-performing models lacked the analytical depth of human experts, often requiring extensive human supervision. The study concludes that LLMs currently serve as powerful assistive tools but still cannot replace the critical validation and synthesis provided by human researchers. Choosing the best LLM to use depends on the task in hand, while several strategies can be implemented to improve the produced output.

Surviving Medical School During a Pandemic: Experiences of New York Medical Students During the Height of SARS-CoV-2

BackgroundThe COVID-19 pandemic dramatically altered the landscape of medical education. While patients overwhelmed hospital systems, lockdowns and social distancing recommendations took priority, and medical education was pushed online. Early in 2020, New York State (NYS) was hit especially hard by COVID-19. ObjectiveThis study sought to understand the effect of the COVID-19 pandemic on medical students well-being and education. MethodsNYS medical students responded to a six-question survey during April and May 2020. Questions assessed self-reported changes in stress levels, academic performance, and board preparation efforts. Open-ended data was analyzed using a modified grounded theory approach. Results488 responses across 11 medical schools were included (response rate of 5.8%). Major themes included: standardized test-related stressors (23%), study-related changes (19%), education and training concerns (17%), financial stressors (12%), and additional family obligations (12%). Second year students reported more stress/anxiety than students in other years (95.9%, p-value< 0.00001). Reported stress/anxiety, effects on exam preparation, and anticipated academic effect varied by geographics. ConclusionsWhile all NYS medical students reported being greatly affected, those closest to the NY City pandemic epi-center and closest to taking the Step 1 exam were the most distressed. Lack of flexibility of the medical education system during this public health emergency contributed to worsened student well-being. It is time to make plans for supporting the long-term mental health needs of these physicians-in-training and to examine ways the academic medical community can better adapt to the needs of students affected by a large public health emergency in the future.

Interdisciplinarity through internationality: results from a US-Mexico graduate course bridging computational and plant science

Interdisciplinarity is used to integrate and synthesize new research directions between scientific domains, but it is not the only means by which to generate novelty by bringing diverse perspectives together. Internationality draws upon cultural and linguistic diversity that can potentially impact interdisciplinarity as well. We created an interdisciplinary class originally intended to bridge computational and plant science that eventually became international in scope, including students from the US and Mexico. We administered a survey over four years designed to evaluate student expertise. The first year of the survey included only US students and demonstrated that biology and computational student groups have distinct expertise but can learn the skills of the other group over the course of a semester. Modeling of survey responses shows that biological and computational science expertise is equally distributed between US and Mexico student groups, but that nonetheless these groups can be predicted based on survey responses due to sub-specialization within each domain. Unlike interdisciplinarity, differences arising from internationality are mostly static and do not change with educational intervention and include unique skills such as working across languages. We end by discussing a distinct form of interdisciplinarity that arises through internationality and the implications of globalizing research and education efforts.
