11028 Background: Cognitive integration (CI) connects foundational science (FS) to medical practice and improves clinical reasoning. While evidence supports CI in medical training, the clinical relevance of FS is often obscure to medical students, particularly in oncology, and few learning materials exist to support CI during clerkships. Providing effective and engaging tools to promote CI may enhance understanding of FS relevance to clinical medicine. We therefore aimed to create an online module to integrate FS into clerkships. Methods: Previous student feedback at our institution advocated for clinically relevant FS content. Applying Cognitive Theory of Multimedia Learning principles, we (an oncologist, a biochemist, and an instructional designer) created a cancer module grounded in the hallmarks of cancer (HoC), a key FS principle. To emphasize clinical relevance, we recorded patient interviews incorporating FS. The module, composed in Qualtrics, includes an introduction and four cases, each starting with a brief patient interview, followed by clinical text, images, questions, and explanations. Content co-created by the oncologist and biochemist combined clinical and FS perspectives and referenced the HoC throughout. We piloted a draft with a focus group of four students. The evaluation plan includes written learner feedback, a case-based pre/post-test, and review of clerkship assessments for evidence of CI. Results: We produced an FS oncology module with an estimated engagement time of two hours, which students may complete over multiple sittings. The development team met monthly over the course of one year. Filming and editing cost $100/hour. Overall, the project required approximately 60 faculty person-hours and 12 instructional designer person-hours. The patients interviewed for the module expressed gratitude for sharing their stories with students. The student focus group yielded unanimously positive feedback about the content, the multimedia format, the level of FS covered, and the use of authentic patient videos to enhance clinical relevance. Students strongly preferred this module compared to prior online learning activities. Conclusions: This novel interactive module can serve as a model for development of clerkship curricula promoting CI. Module creation based on real patients resulted in authentic story-telling and enhanced FS relevance. Content development involving a clinician and a basic scientist aligned with CI goals. Limitations include the need for funding and instructional design assistance. A randomized controlled trial comparing a series of novel FS modules to older recorded lectures may demonstrate improved outcomes. Involving learners in curriculum development may decrease faculty burden and increase student interest in FS.
