Current reforms in medical education call for future physicians who are both scientifically competent and ethically aware. However, foundational chemistry courses often emphasize mechanistic content over the formation of professional values, creating a gap between chemical knowledge and clinical practice for medical students. To address this, we developed and evaluated a blended instructional model for teaching “amino acids, peptides, and proteins” in an organic chemistry course for first-year clinical medicine students. The model integrates an Outcome-Based Education (OBE) approach with the BOPPPS (Bridge-in, Objective, Preassessment, Participatory Learning, Postassessment, Summary) framework and was delivered via a digital learning platform. It incorporates clinical case analyses, molecular visualization, ethical debates, and project-based learning to simultaneously advance students’ conceptual understanding, practical competency, and ethical reasoning. Implementation data show high engagement: 95.2% of students completed online self-study modules and 91.0% actively participated in ethics-focused discussions. Learning gains were significant, with post-test accuracy on protein structure–function relationships improving from 62.4% to 88.7%. Qualitative analysis revealed that 56% of students achieved “Exemplary Integration”, demonstrating clear connections between molecular concepts and ethical considerations. The OBE-BOPPPS model thus offers a structured, replicable strategy for embedding humanistic and ethical dimensions into foundational chemistry instruction, effectively preparing students to become scientifically adept and ethically conscious practitioners.
