Rethinking Basic Science Teaching in Medical Education: A Viewpoint on Its Past, Present, and Future

Basic sciences remain a cornerstone of medical education, but the terms of the debate about their importance have changed. The central risk is no longer their formal exclusion from medical curricula but their curricular invisibility: the gradual dilution of mechanistic reasoning within integrated, technology-mediated, and institutionally unequal training environments. In this Viewpoint, we revisit the past, present, and future of basic science teaching to argue that reform must protect conceptual progression, curricular visibility, and clinical transfer. Active learning, curricular integration, digital tools, and AI may strengthen scientific literacy, but only when they are anchored in faculty development, institutional support, and explicit commitments to rigor and equity.
