Introduction/Rationale: This study examines the educational value of traditional chalk-and-board teaching in immunology courses. Despite the increasing use of digital tools and multimedia platforms, the chalk-and-board approach remains effective, especially for immunology, which requires deep conceptual understanding and visual-spatial reasoning. Immunological processes—such as antigen presentation, cytokine signaling, and clonal selection—are inherently complex and benefit from real-time illustration and explanation. Drawing and writing on the board helps students engage cognitively, enabling them to follow the logical flow of ideas and retain information more effectively.
Methods: We at Chicago State University used appropriate surveillance methods, such as direct observation, digital monitoring, biometric sensors, and self-reporting tools. Ensured ethical practices by obtaining informed consent, protecting privacy, and maintaining transparency. Used tools such as LMS analytics, screen-monitoring software, and video analysis platforms to collect data. Analyzed the data using qualitative or quantitative methods.
Results: The results indicated that chalk-and-board teaching also enhances clarity and pacing, enabling instructors to modify explanations based on student feedback and comprehension. It reduces technological distractions and fosters active note-taking and participation. Furthermore, the visual reinforcement of cellular interactions and molecular pathways improves understanding of spatial relationships essential to immunological mechanisms. However, limitations include time constraints and decreased accessibility for students with specific needs.
Conclusion: This presentation advocates for reevaluating chalk-and-board teaching methods in science education, not as outdated, but as a complementary tool that enhances cognitive processing and visual learning. Future research should explore its effects on student performance, engagement, and long-term retention in immunology and other biomedical sciences.
